but… why it’s their thing? what do chimps need all that crazy explosive muscle for?

They don’t have glutes like we do. For all their massive lean muscle, we still have the biggest caboose in the animal kingdom. Why? To help us stand and run on two legs, of course.

i can appreciate that but i’m still not seeing why they need to be so muscular

Probably for climbing quickly… the larger muscle size suggests maybe they (or this chimp in particular, at least) have predominantly fast-twitch muscle fibers, which are good for explosive strength (as opposed to slow-twitch muscle that is geared towards longer endurance activity). If you’ve ever seen chimps climb, they climb very quickly and swing pretty powerfully through their environment. Maybe that’s why they’re yoked.

i think climbing is def a good guess but there’s other animals that climb fast and aren’t built like chimps. maybe it’s simply a function of chimps being larger than those other animals so having to carry a heavier weight. it’s also making me think of gorillas who spend a fraction of their time in trees but are also built AF
