He is also known as carl linnaeus or carl von linne. Systema nature = system of nature: had originally put humans and orangutans in the same genus. Infant dependency usually lasts from 1 to 16.

Problem #2 = squirles: not all arboreal animals have grasping hands. In conclusion arboreality is insufficient to account for the evolution of primates: the comparative method is used for this hypothesis testing. Reason for these animals to have forward facing eyes is for depth perception. Earliest fossil primates found were small nocturnal predators. Forward facing eyes needed because they were nocturnal.
