Early primates

Question

Early primates

Quizplus · Accepted Answer

Many early primates, such as adapids and omomyids, had large eyes indicating that they were adapted to living in low light conditions, which suggests they were likely nocturnal. Primates did not become fully diurnal until much later in their evolution.

Answer: B
 Many early primates had claws, which were likely used for grasping onto branches and other objects in their arboreal habitats. However, over time, primates developed flatter nails that were better suited for grooming and manipulating objects.

Answer: D
 All extant primates are descended from early primates, so while some lineages did not survive, they did leave descendants. Therefore, this answer is not accurate.

C is not a good option because there is no evidence to suggest that early primates were bipedal. In fact, most early primates were quadrupedal, meaning they moved on all four limbs, and it took many millions of years of primate evolution before bipedalism emerged.
