There are many similarities between non human primates and humans. Every trait reflects an evolutionary decision at some point in history. The fact that were homeotherms allows us to maintain a central body heat and can pretty much adapt or live anywhere, where as non homeotherms like snakes body will freeze up in environments that aren’t hot all the time. Primates such as monkeys have many similarities like our body, behavior because of our similarities we can really observe primates and understand how they use traits and gives us some insight on why we evolved the way we did and why we have the traits we do. For example like stated in the first video, most non human primates like monkeys/apes have prehensile digits (toes and fingers) just like we do. They use this specific trait to maneuver in trees, where as we use it to grab or hold things. We have it because our ancestors had it, which infers that our ancestors once depended on trees or lived in that environment. Another example is stereoscopic vision which is something we still use and have today, that primates such as monkeys/apes use to see at night. Non of the information exactly surprised me about non human primates and our connection, but more so just made me want to look into outer things that we cold have alike that could of been a result of evolution. I believe we already have so much knowledge on and understanding on biology, behavior and culture by studying non- human primates, although theres always so much more to learn that could be beneficial to us and them. Some things I would personally like to learn more about is the behavior aspect.
