Hunting: -pursue other living things for food.
- In apes/primates , OWP, hunts other primates, birds
- In chimps and bonobos as well, high cooperative
Looking at DNA and deces to see if gorillas, bonobos and chimps eat meat . there will
be DNAfrom other organisms. Using barcodes to identify dna from other mammals
- Can also due to contamination.
- Communities don’t think gorillas eat meat
- Food sharing is crucial.
- Can have even distribution of food or clumped food. Lead to aggression,
- Reduced feeding opportunity when it is clumped
- Can defend food resources or share food with other individuals
Chimps and bonobos have different social hierarchy. Bonobos eat evenly shared food,
terrestrial l herbal vegetation. Chimps have clumped food sources and more hierarchy.
Other than group size , there is also predation. Need to worry about predators. More
individuals in a group is better to detect predators. Large group size becomes
resources , lead to sexual selection. If there are more females in one area, can trigger
male-male competition, leads to different morphological differences between males
Transmission of disease and pathogens – play a factor in group size
Distribution of food matters, relates to sexual reproduction.
Is cooperation is needed for hunting? Defend food resources?
[all these affect evolution]
