Infanticide in Primates

Conclusions based on Reasoning

Acknowledgment of the role of evolutionary pressures in shaping primate behavior

Recognition of infanticide as a complex and debated topic

Primate Species and Social Structures

Emphasis on harem structures (one male, many females)

Infanticide Rates in Harem Structures

Impact on Females in Harem Structures

Evolutionary adaptations and counter-strategies by females

Strategies employed by females, e.g., mating with multiple males to confuse paternity

Limited options for females to protect their offspring

Evolutionary instinct: increasing chances of passing on male's DNA.

Shortening inter-birth period for females in estrus

The majority of infanticides occur in one-male groups.

Examples of primate species: apes, chimps, humans, baboons, langurs

Reasons for Infanticide in Primates

Ethical Considerations

The impact of human intervention on natural events in primate groups

Challenges in balancing research objectives with ethical concerns

Evolutionary Perspectives

Ongoing debate: Is infanticide a sign of dysfunction or a normal part of primate groups?

Changes in hierarchy within primate groups

Social pathology and exploitation within primate societies

Males' desire to reproduce with females who have already given birth

Resource competition among males

Prevalance of infanticide in the primate species as a whole, leads us to believe that this is part of our natural selection.

Comparison with Other Primate Societies

Evolutionary adaptations to cope with forced procreation in certain species

Examples from other animal species (e.g., ducks) practicing forced procreation

Cooperation in raising offspring observed in some primate groups

Observations in fission-fusion societies (e.g., chimps)

Definition: The act observed in certain cultures of intentionally causing the death of newborns shortly after their birth due to various reasons, including societal norms or considerations, often driven by circumstances perceived as rendering the infants undesirable.
