It is clear that certain traits in early primate evolution played a key role in leading to the survival and further development of members of the order. Explain how traits such as manual dexterity, upright posture, acute vision, larger brain, extended infant care, and modified teeth laid the groundwork for the evolution of humans
What will be an ideal response?
The development of an opposable thumb provided better gripping for climbing, grasping, and tool use. A more upright posture allowed use of the opposable thumb as the primates became bipedal. Stereoscopic vision provided depth perception essential for hunting and escaping. The larger brain capacity allowed for better communication and also for the early primate to obtain food more efficiently. Extended infant care meant that infants could be taught more and have more time to develop before having to fend for themselves. This allowed for increased knowledge transfer from adult to offspring. Modified teeth allowed for increased variety in diet.
