Describe how the characteristics of primates make them well adapted for an arboreal lifestyle

Arboreal lifestyle is characterized by increased stay in trees and forested areas. Primates which have got this kind of life tend to spend   most of their time in trees   while sleeping, eating, or playing.  These primates have got well developed   feet and hands to enable them crawl along branches and also reach for food which in most cases tend to be fruits. These animals also have got impressive sense of sight which enable them to develop depth perception which is highly important for them as they move from one tree branch to another.

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
