How Prevalent Is Infanticide Among Great Apes?

Infanticide, the intentional killing of infants or young offspring, is a behavior that has been observed in numerous animal species including primates. Infanticide among great apes has received much attention due to its potential evolutionary significance and impact on social dynamics within ape communities.

Despite extensive research on this topic, it remains unclear how prevalent infanticide is across different species of great apes.

Several theories have been proposed to explain why some male great apes engage in infanticidal behaviors. One hypothesis suggests that males kill unrelated infants as a way to increase their own reproductive success by eliminating competition for resources and mating opportunities.

Another theory proposes that males may kill infants when they take over a new group in order to reduce the chances of being attacked by rival males who may seek revenge against them for past harm inflicted upon their offspring.

In this article, we will delve into the current understanding of infanticide among great apes and explore what factors contribute to this controversial behavior.

Definition And History Of Infanticide

Infanticide is the act of killing an infant, which can have devastating consequences for a species’ survival. This behavior has been observed in various animals, including some great apes such as chimpanzees and gorillas. Infanticide prevention strategies are crucial to protect the young of these endangered species.

Infanticide’s historical background reveals that this practice was not limited to just humans or animals; it also occurred among early societies worldwide. The ancient Greeks practiced infanticide by abandoning unwanted infants on hillsides, while Romans allowed fathers to kill their newborns if they deemed them unfit for life. In modern times, infanticide continues with alarming rates reported in countries like India and China where girls were killed due to gender discrimination.

Cultural influences play a significant role in determining whether infanticide will occur within animal populations. Chimpanzee groups from different locations exhibit varying levels of infanticidal behaviors resulting from cultural differences passed down through generations.

For example, researchers found higher incidences of infanticide amongst males in Gombe National Park than those at Mahale Mountains because male chimps hunted more frequently outside of their troop range than females who primarily focused on feeding within the group territory.

Understanding the prevalence and causes of infanticide across different species provides insight into how we can prevent its occurrence effectively. Great apes serve as an excellent case study as they share many characteristics with humans such as complex social structures, tool use, and communication skills. Therefore studying infanticidal behaviors among great apes could help identify effective prevention methods that could be applied across multiple species without risking harm to individuals involved.

Great Apes As A Case Study

Great apes have been the subject of numerous case studies investigating their behavioral adaptations in different environments. These primates are known for their complex social structures, which vary depending on species and geographical location. One commonality among great apes is that they exhibit a wide range of behaviors related to infant care, including infanticide. However, it is important to note that not all great ape populations engage in this behavior at the same rate.

Case studies have shown that factors such as food availability, group size, and male dominance hierarchy can influence infanticide rates among great apes. For example, chimpanzee communities with larger groups and more dominant males tend to experience higher levels of infanticide compared to those with smaller groups and less competitive males. In contrast, gorillas generally have lower rates of infanticide due to their herbivorous diet and cohesive family groups led by one dominant silverback male.

Despite these differences in infanticide rates among great apes, there are still patterns that emerge across species. For instance, researchers have observed that most cases of infanticide involving female perpetrators occur during periods of resource scarcity or high stress levels within the community. Male perpetrators, on the other hand, may engage in infanticide as a means of eliminating potential rivals for mating opportunities.

Overall, studying great apes provides valuable insights into the diversity of primate social systems and how they adapt to changing environmental conditions. Understanding the underlying factors influencing infanticide rates can help shed light on broader questions about human evolution and why certain behaviors evolved in some societies but not others.

Transition: With this understanding about various factors affecting infanticide rates among great apes, we can now focus specifically on chimpanzees – a species notorious for its high incidence of this behavior – and examine their unique patterns of infanticide in greater detail.

Chimpanzees: Infanticide Rates And Patterns

Infanticide among chimpanzees has been documented in many studies, with some estimates of its prevalence ranging from 8-33%.

Evidence suggests that infanticide among chimpanzees is more common when a new male takes over a group and is more likely to occur if the victim is a female.

Studies also suggest that infanticide may be used as a way to increase access to females and that the victims are often unrelated to the perpetrator.

Additionally, infanticide has been observed to be used as an act of aggression between males and as a form of competition for resources.

Chimpanzee Infanticide Rates

Infanticide is a common phenomenon observed in chimpanzee societies. While it is difficult to determine the exact rate of infanticide among chimpanzees due to variations in study methods and populations, research has shown that up to 20% of infant deaths are attributed to infanticide.

Chimpanzee infanticide occurs when an adult male kills an unrelated infant or takes over another male’s group and subsequently kills all infants within the group. The causes behind chimpanzee infanticide are multifaceted. It is believed that males engage in infanticidal behavior as a means of eliminating potential competition for resources, including food and mating opportunities.

Additionally, females may also participate in infanticidal behavior as a way to increase their own reproductive success by reducing competition from other mothers’ offspring. The consequences of this behavior can have significant impacts on chimpanzee social dynamics and population genetics.

When compared with other great apes such as orangutans and gorillas, chimpanzees exhibit higher rates of infanticide. This could be due to differences in social structures between these species, with chimpanzees living in larger communities where there is greater potential for resource competition and conflict. Alternatively, it could be related to differences in ecological pressures faced by each species.

In conclusion, while not unique among great apes, chimpanzee infanticide rates are notably high and have complex causes with significant consequences for both individuals and populations. Further research into the underlying factors behind this behavior will help shed light on the evolution of primate societies and aid conservation efforts for endangered species like chimpanzees.

Chimpanzee Infanticide Patterns

Chimpanzee infanticide is a well-known phenomenon among primatologists due to the notable frequency of occurrence. The causes and consequences of this behavior have been studied extensively, but there are still gaps in our understanding. One area that requires further exploration is the patterns of infanticide observed within chimpanzee communities. By examining these patterns, we can gain insights into the effectiveness and limitations of maternal strategies for protecting offspring.

Studies have shown that certain factors influence the likelihood of infant mortality due to infanticide in chimpanzees. For example, infants born to lower ranking mothers or those whose mothers do not receive support from other group members are more vulnerable to being killed by males who seek to eliminate potential competition. Additionally, when male takeover occurs, it often results in all unrelated infants being killed regardless of their age or sex.

The ability of females to protect their offspring from infanticidal attacks varies depending on several factors such as social status, experience, and knowledge of safe locations within the habitat. In some cases, protective behaviors like staying close to dominant males or seeking refuge high up in trees may be effective at preventing attacks. However, there are limitations to these strategies since they rely heavily on external circumstances beyond an individual’s control.

Overall, while chimpanzee infanticide rates remain high compared to other great apes, it is important to recognize that these events occur under specific conditions and are not representative of all primate species’ behavior towards infants. Understanding the different aspects influencing this behavior will help us develop better conservation strategies aimed at mitigating its negative effects on populations and ensure future generations’ survival.

Gorillas: Infanticide Rates And Patterns

Gorillas are one of the four great ape species that exist today, alongside chimpanzees, bonobos, and orangutans. These primates are notorious for their physical strength and impressive size, with males weighing up to 400 pounds.

Gorilla behavior is also fascinating – they live in cohesive social groups led by a dominant silverback male who protects his females and offspring from external threats. Maternal care among gorillas is crucial for the survival of their young. Female gorillas invest a lot of time and energy into raising their infants during the first few years of life. This includes carrying them around on their backs, nursing them regularly, and teaching them how to find food.

Despite this investment in maternal care, however, infanticide rates among gorillas have been documented in some populations. Infanticide in gorillas occurs when a new dominant male takes over a group from another male. In order to establish his dominance and ensure reproductive success, he will often kill any infants that were fathered by the previous male. Infants may also be killed if they pose a threat to the safety or well-being of other individuals within the group.

While infanticide is not common among gorillas overall, it can have significant effects on population dynamics in areas where it does occur. The reasons behind these behaviors are complex and require further investigation into factors such as genetic relatedness, resource availability, and social dynamics within groups. Understanding these patterns can provide insight into primate evolution and shed light on our own human origins as well.

Orangutans: Infanticide Rates And Patterns

Gorillas are one of the great ape species that have been observed exhibiting infanticide. Infanticide rates among gorillas vary depending on several factors such as age, sex, and social status. Males in particular tend to be more likely to commit infanticide, especially during times when they are trying to establish dominance over a group.

Orangutans are another great ape species that have been known to engage in infanticide. Unlike gorillas, however, female orangutans have also been observed committing this behavior. The rate of infanticide among orangutans is relatively low compared to other great apes, but it still occurs. Some researchers have suggested that habitat destruction may play a role in increasing the likelihood of infanticide among orangutans.

Infanticide prevention strategies have been implemented for many great ape species including gorillas and orangutans. These strategies often involve monitoring groups closely and intervening if necessary to prevent harm from being inflicted upon infants or juveniles within the group. However, with continued habitat destruction and loss of resources for these animals, preventing infanticide may become increasingly difficult.

While gorillas and orangutans have both shown instances of infanticide, there is another great ape species worth examining – bonobos. How do bonobo communities handle incidents of infanticide? Are their rates comparable to those seen in gorilla and orangutan populations?

Bonobos: Infanticide Rates And Patterns

Bonobos are one of the four great ape species and possess a unique social structure characterized by female dominance, promiscuous sexual behavior, and strong mother-infant bonds. Despite their peaceful reputation, infanticide has been observed among bonobos in the wild. Infanticide rates vary across populations with some communities experiencing higher frequencies than others.

Bonobo maternal behavior plays a crucial role in preventing infanticide. Mothers protect their infants from male aggression and form alliances with other females to increase their chances of survival. In addition, mothers use vocalizations to communicate distress signals when threatened, which alerts nearby adults that can intervene on behalf of the infant. These strategies have proven effective as most infanticidal attacks occur during times when mothers are not present or distracted.

In some cases, males may still attempt to kill an infant despite these preventive measures. However, research suggests that certain factors such as relatedness between attacker and victim or limited access to resources may influence infanticide rates in bonobos. For instance, unrelated males are more likely to target offspring compared to those they share kinship with while high food availability reduces competition for resources thus decreasing instances of infanticide.

Understanding how bonobos prevent infanticide is critical for conservation efforts aimed at protecting this endangered species. Researchers hope that continued study of maternal behaviors will provide insight into new prevention strategies and help mitigate risks posed by human activity such as deforestation and hunting pressures.

Factors That Influence Infanticide Rates

Bonobos are one of the few species within the great apes that exhibit low rates of infanticide. However, this is not the case for all great ape species. Infanticide has been observed in other great ape species such as chimpanzees and gorillas, but its prevalence varies depending on several factors.

Factors play a significant role in determining the likelihood of infanticide among great apes. For instance, male dominance has been identified as a potential cause of increased rates of infanticide. In some cases, alpha males may kill infants sired by subordinate males to eliminate competition for resources or mating opportunities.

Additionally, food scarcity can also drive up instances of infanticide, particularly when mothers struggle to provide adequate nutrition for their offspring. Another factor that may influence infanticide rates is social organization. Chimpanzee communities tend to be more aggressive and territorial than bonobo societies, which could explain why they have higher levels of infanticide.

Conversely, orangutans live relatively solitary lives with minimal interactions between individuals; therefore, infanticide incidents are rare in these primates. In conclusion, there are various causes contributing to differences in infant mortality across different primate species. Factors like male dominance and resource availability appear to be important determinants impacting infanticide rates among great apes. Next, we will explore how sexual selection plays a role in understanding patterns of infanticide among primates.

Sexual Selection And Infanticide

Infanticide is a phenomenon observed in many animal species. This practice involves the killing of infants by conspecifics, often males, who have no genetic ties to them. Theoretically, infanticide can enhance male reproductive success because it eliminates potential rivals for mating opportunities with females.

Sexual selection theory posits that sexual competition between members of one sex (usually males) for access to the other sex (usually females) selects for traits that increase their chances of reproductive success. Evolutionary hypotheses suggest that infanticidal behaviors may be linked to certain reproductive strategies employed by great apes.

For instance, some researchers contend that gorilla males engage in infanticide as part of a strategy to reduce female inter-birth intervals and increase offspring survival rates. This hypothesis suggests that male gorillas kill infants from newly-arrived females so they can mate with these females more quickly than if they were caring for an infant. In contrast, chimpanzees are known to form alliances among males and cooperate in order to obtain exclusive mating rights with particular females. According to this view, chimpanzee males commit infanticide on rival groups’ offspring as a way to weaken their competitors’ social bonds.

Three key items emerge from current research on great ape infanticide:

  1. Infanticide appears most common among primates living in large multi-male/multi-female societies.
  2. Males typically perpetrate such acts; however, females may also play a role.
  3. Great ape species differ markedly in frequency and context-specific forms of infanticidal behavior.

Overall, the evolutionary basis behind infanticidal tendencies remains complex and multifaceted across primate taxa. While seemingly contradictory behaviors exist within each species—such as long-term protection versus short-term aggression—the evidence suggests that adaptive responses depend heavily upon ecological context and variable selective pressures.

The next section will explore how resource competition and infanticide are interconnected in great ape societies. Understanding the motivations behind this behavior is crucial to appreciating how such practices may have evolutionary consequences for primate life histories and reproductive strategies.

Resource Competition And Infanticide

Resource competition plays a significant role in shaping the reproductive strategies of great apes. In many cases, access to food and other resources can determine an individual’s ability to reproduce successfully. This is particularly true for males, who often engage in aggressive behaviors towards one another as they compete for access to fertile females.

One of the consequences of resource competition is infanticide, which has been observed in several species of great apes. When new males enter a community or take over a group, they may kill any infants that are not their own. This behavior serves two purposes: eliminating potential rivals and bringing females back into estrus more quickly.

Female great apes have also been known to commit infanticide under certain circumstances, such as when resources are scarce or when they perceive their offspring as being weak or sickly.

Infanticide is just one aspect of the complex social dynamics that exist among great apes. While it may seem counterintuitive from a human perspective, this behavior can actually increase an animal’s chances of passing on its genes by removing competitors and increasing mating opportunities.

However, it also highlights the importance of understanding how resource competition affects reproductive success and population dynamics within these species.

Moving forward, further research on the social dynamics and infanticide in great ape populations could shed light on how these animals adapt to changes in their environments and interact with each other within different contexts.

By gaining a better understanding of these factors, we may be able to develop conservation strategies that help protect endangered species while promoting healthy ecological relationships between humans and our closest primate relatives.

Social Dynamics And Infanticide

Resource competition and infanticide are closely related phenomena in the animal kingdom. In many species, males compete fiercely for resources like food, territory or mates. This competition can lead to infanticide when a male kills an infant that is not his own as a way of eliminating genetic competitors and increasing his chances of passing on his genes.

Social dynamics also play a significant role in infanticide among great apes. Dominant males often have greater access to mating opportunities and may kill infants sired by lower-ranking males to reduce their reproductive success. However, females are not immune from this behavior either; some studies suggest that female chimpanzees may commit infanticide against unrelated infants they perceive as a threat to their offspring’s survival.

Infanticide can also be learned socially within groups of primates. For instance, young male baboons who witness adult males killing infants are more likely to engage in the same behavior themselves later in life. Similarly, captive orangutans have been observed copying each other’s violent behaviors towards infants even though such acts do not occur naturally in the wild.

In summary, dominance hierarchies and social learning appear to contribute significantly to infanticide among great apes.

While these factors make it challenging for mothers to protect their offspring successfully, various maternal strategies exist that help increase their chances of doing so effectively. The following section will explore some examples of these protective measures taken by primate mothers throughout different stages of infancy and beyond.

Maternal Strategies To Protect Offspring

Maternal behavior is crucial to the survival of offspring in great apes. Mothers have developed various strategies to ensure the safety and well-being of their young, including protecting them from predators, providing food and shelter, and socializing with other members of the group. These behaviors not only increase the chances of offspring survival but also contribute to a healthy population.

One strategy employed by mothers is carrying their infants on their back or chest for extended periods. This physical contact provides warmth and protection against potential threats while allowing mothers to move freely around their environment.

For example, in orangutans, mothers carry their young until they are six years old, which allows for more extensive exploration without leaving offspring vulnerable.

Another maternal behavior that promotes offspring survival is nursing. The milk produced by mothers contains vital nutrients that help build immunity against disease and promote growth. Breastfeeding also fosters bonding between mother and child as it releases hormones associated with feelings of affection and trust.

Finally, another critical aspect of maternal behavior among great apes is teaching skills necessary for independence. As youngsters grow older, mothers gradually allow them greater freedom while still keeping a watchful eye on them. They teach valuable skills such as foraging techniques or how to avoid danger so that when the time comes, offspring can survive independently without relying solely on their mother’s care.

The importance of maternal strategies for great ape conservation cannot be understated. When habitat loss or hunting pressures populations, strong maternal bonds may become even more critical factors influencing individual success rates within groups. Understanding these behaviors can inform conservation efforts aimed at promoting species recovery during times where environmental stressors threaten existence itself – offering renewed hope both now and into future generations yet unknown!

Implications For Conservation

Maternal Strategies to Protect Offspring are crucial for the survival of any species, including great apes. However, these strategies can be undermined by several factors such as limited resources and predation threats from other animals in their habitat.

Infanticide is one of the most significant challenges faced by great ape mothers, especially when dominant males kill offspring sired by rivals or newly acquired females. Studies on infanticide among great apes reveal that it occurs sporadically across different species.

In chimpanzees, infanticide usually happens during times of social instability, where male aggression rises due to reduced food availability or territorial conflicts. On the other hand, gorillas have a lower incidence of infanticide because they live in stable groups led by silverback males whose primary role is to protect infants from external threats. Orangutans also experience infanticide but at much lower rates than chimpanzees since they are solitary creatures with minimal risk of intergroup violence.

Conservation strategies aimed at protecting great apes must consider all potential ecological impacts resulting from infanticide. The loss of an infant affects not only the mother but also has cascading effects on group dynamics and genetic diversity within populations. For instance, if there’s a decline in reproductive success due to high rates of infanticide, then this could affect population stability and ultimately lead to extinction.

Ethical considerations surrounding conservation efforts for great apes are complex and multifaceted. One area of concern relates to how humans interact with these primates in captivity or while conducting research studies on them. There is a need for greater awareness about ethical practices related to handling these animals while ensuring their welfare is protected throughout the process. Additionally, we should strive towards developing sustainable conservation models that prioritize animal rights alongside human needs and interests without compromising either party’s well-being.

Ethical Considerations

The topic of infanticide among great apes raises ethical implications that need to be addressed. It is important to note that the behavior of these animals should not be judged based on human morality alone, but rather through a lens that considers their natural instincts and behavior in the wild. However, it is also essential to recognize the potential harm or impact such actions may have on individual members of the population and its overall survival.

Philosophical debates arise regarding how we approach this issue as researchers and conservationists. Some argue that non-intervention and observing nature unfold without interference are necessary for understanding animal behavior truly. Others believe intervention is needed when an action threatens the well-being of individuals or the species’ chances for survival. Such debates highlight the complexity involved in studying animal behavior ethically.

Furthermore, there is a risk of applying human values onto animals when analyzing their behaviors. Infanticide has been noted in multiple primate species, including chimpanzees and gorillas, leading some to question whether they possess moral agency similar to humans.

It is crucial to avoid anthropomorphizing animal behaviors while still considering ethical implications surrounding them. In conclusion, exploring infanticide among great apes reveals complex philosophical debates about how researchers should approach these issues ethically.

While recognizing non-human primates’ unique behaviors and avoiding anthropomorphic interpretations, it remains critical to consider potential harm caused by interfering with natural behaviors or neglecting those that could affect populations’ long-term survival rates. Moving forward, future research directions should continue investigating both evolutionary pressures driving infanticidal behaviors across different primate species and assessing interventions aimed at mitigating negative consequences associated with infant killing events within populations where possible.

Future Research Directions

  1. Investigating factors associated with infanticide among great apes could include studying the role of dominance and competition in their social dynamics.

  2. Examining how environmental context such as food availability and habitat quality may influence infanticide frequency could also be conducted.

  3. Further research could also analyze how the presence of multiple males or female transfer affects the likelihood of infanticide among great apes.

  4. Investigating the effects of infanticide on the reproductive success of the perpetrator and the survival of the offspring could also provide further insight into the prevalence of infanticide among great apes.

Investigating Factors Associated With Infanticide

The prevalence of infanticide among great apes has been well documented, and this phenomenon is influenced by various factors. Understanding the underlying causes can help develop strategies to prevent it. Consequently, future research directions must investigate these factors to mitigate or minimize its occurrence.

One factor affecting infanticide rates is the availability of food resources in their habitat. Great apes that live in areas with limited resources are more likely to engage in infanticidal behavior because they cannot afford to care for additional offspring.

Additionally, the age and social status of male individuals also play a significant role as dominant males may kill infants sired by other males to increase their reproductive success.

Another crucial factor associated with infanticide is maternal-infant relationships. Primates depend on close bonds between mothers and offspring for survival. When such bonds break down due to stressors like competition over resources or aggression from other individuals within their group, infanticide becomes more prevalent.

Future research should focus on investigating prevention strategies aimed at reducing the incidence of infanticide among great apes. One possible approach could be providing supplementary feeding programs for primates living in resource-limited habitats, which can reduce intra-group competition and thereby decrease infant mortality rates caused by cannibalistic behaviors.

Another strategy could involve reintroducing captive-bred primates into natural habitats but under managed conditions where aggressive individuals are separated from others.

In conclusion, examining factors influencing infanticide rates provides insights into developing effective intervention measures against this behavior among great apes populations. Future studies should prioritize understanding how environmental influences impact primate communities while also testing innovative solutions towards mitigating the effects of this complex issue on endangered species worldwide.

Examining The Influence Of Environmental Context On Infanticide Frequency

The frequency of infanticide in great apes appears to be influenced by various environmental factors. Therefore, understanding these influences is critical for developing effective intervention measures against this behavior among primate populations.

One aspect worth examining is the impact of environmental context on infanticide frequency. Research has shown that primates living in areas with limited resources are more likely to engage in cannibalistic behaviors due to competition over food and space. Moreover, behavioral adaptations may also play a role in infanticidal tendencies within specific environments.

For instance, certain social structures may increase the risk of infant mortality rates as dominant males seek to eliminate offspring sired by other males to increase their reproductive success. On the other hand, some habitats may provide opportunities for maternal-infant bonding, thereby reducing stressors associated with intra-group competition and aggression from others.

By investigating how environmental factors shape primate communities’ behavior patterns regarding infant survival, we can develop innovative solutions towards mitigating the effects of this complex issue on endangered species worldwide. One possible approach could involve designing conservation strategies aimed at enhancing habitat quality or promoting sustainable land-use practices that support healthy ecosystems where primates can thrive without compromising their ability to reproduce successfully.

In conclusion, exploring the influence of environmental factors on infanticide frequencies provides valuable insights into developing practical interventions against this phenomenon among great ape populations. Future research should prioritize studying the adaptive mechanisms utilized by primates under different ecological conditions while testing out potential management approaches aimed at minimizing negative impacts on threatened species worldwide.

Conclusion: Understanding Infanticide In Great Apes

Infanticide is a complex behavior that has been observed in several great ape species. Although it is not universally present, its prevalence varies across different populations and contexts.

The occurrence of infanticide highlights the importance of studying social behaviors among primates to better understand their evolutionary history.

Evolutionary implications of infanticide have long been debated, with some researchers suggesting that it serves as an adaptive strategy for males to eliminate offspring that are unlikely to be their own. Others argue that it is an incidental byproduct of other behavioral traits such as territoriality or aggression.

Regardless of its function, the fact remains that infanticide can have significant impacts on population dynamics, genetic diversity, and even social structure.

Cultural variations also play a role in shaping the frequency and context of infanticidal behavior. For example, chimpanzees living in areas where food resources are scarce may engage in more frequent instances of infanticide than those inhabiting regions with abundant food sources. Similarly, differences in male-female ratios within groups can influence whether or not infanticide occurs at all.

Overall, understanding infanticidal behavior among great apes requires consideration of both biological and cultural factors. While the prevalence of this behavior varies across different species and populations, its existence underscores the complexity and richness of primate social systems.

As we continue to study these fascinating creatures, we gain deeper insight into our shared evolutionary past and the diverse ways in which life on Earth has adapted over time.

Frequently Asked Questions

What Are The Similarities And Differences Between Infanticide In Great Apes And Infanticide In Other Animal Species?

Infanticide is a common phenomenon among various animal species, including great apes. While there are similarities in the behavior across different animals, it is important to note that infanticide can vary depending on evolutionary implications and psychological effects.

In terms of the former, it has been suggested that male primates may engage in infanticidal behavior as a means of increasing their own reproductive success by eliminating offspring sired by rival males. Additionally, while the immediate impact of infanticide may be death for the infant, there can also be long-term psychological effects on surviving members of the group, such as increased stress levels or altered social dynamics.

Further research into these topics can provide insight not only into animal behavior but also human psychology and evolution.

How Do Great Ape Mothers Typically React To The Threat Of Infanticide, And What Strategies Do They Use To Protect Their Offspring?
