Primates, including humans, share physical traits that distinguish them from many other mammals. Their behavior also varies with their environment, and studying that variation helps anthropologists understand both human evolution and the possibility of culture in other primates.
Primates share a collection of anatomical and life-history traits. No single feature on this list is necessarily unique to primates; together, however, they form a recognizable pattern.

What is binocular vision?
It is the ability to use both eyes to see one image, supporting depth perception.
What is the arboreal theory?
It proposes that primate traits such as grasping hands and feet evolved as adaptations to living and moving in trees.
What does the visual predation hypothesis propose?
It proposes that forward-facing eyes, grasping extremities, and nails helped early primates hunt insects and other small prey in forest habitats.
What resources are emphasized by the angiosperm theory?
Flowering plants provide resources such as nectar, seeds, and fruits; visual and tactile abilities may have helped primates find and handle these foods.
What is termite-fishing, and why is it relevant to culture?
Termite-fishing is the use of a stick to extract termites from a mound. When older chimpanzees teach the technique to younger ones and it is passed on, it provides evidence of learned knowledge shared within a group.
Quiz questions
Which kind of vision allows both eyes to contribute to viewing the same image?Answer: Binocular vision
How do sensitive fingertip pads and opposable digits mainly benefit primates?Answer: They improve grasping and object handling.
Which pairing correctly describes the chimpanzee hunting examples at Gombe and Fongoli?Answer: Fongoli: stick-speared galagos; Gombe: hand-caught red colobus.
Which behavior would provide evidence of cultural transmission among chimpanzees?Answer: Older chimps teach younger chimps a stick technique, which spreads within the group.
Which hypothesis proposes that some primate traits helped ancestors catch insects and other small prey?Answer: The visual predation hypothesis
