The lemur branched off the primate tree about 40 million years ago. He can be quite peaceful before discovering that humans kill and maime. He is undersexed because he is so physically powerful. He seeks to look in the eyes of the human to see what manner of creature he is. Incidentally, chimps seem hairy because their hair is coarse.
Humans have as many hair follicles as chimps.
The bononobo is also called the pigmy chimp. It looks surprisingly different when placed side by side with the common chimp. These chimps practice indiscriminate sexual contact. Our more human primate family tree. Go back to primates.
