Document Summary
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 dna from other organisms. Using barcodes to identify dna from other mammals. Can have even distribution of food or clumped food. Reduced feeding opportunity when it is clumped. Can defend food resources or share food with other individuals. 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. 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 and females. Transmission of disease and pathogens play a factor in group size. Distribution of food matters, relates to sexual reproduction.
