List and describe the development of anatomical features that occurred during primate evolution.
What will be an ideal response?
Mobile forelimbs and hindlimbs: primates have opposable thumbs and big toes (except for humans), which results in a grip that is powerful and precise.
Binocular vision: the snout is shortened, allowing the eyes to be on the front of the head. This produces an overlapping field of vision, giving primates a three-dimensional view.
Large, complex brain: the cerebral cortex is expanded. This portion of the brain is devoted to sight, as well as controlling and processing information received from the hands and thumbs. This results in good hand-eye coordination.
Reduced reproductive rate: primates tend to have one birth at a time, which allows for an increase in parental care of the offspring. An extended juvenile period allows for an emphasis on learned behavior and complex social interactions.
