      I don't think so. From what I've read, human muscles and chimp muscles are mostly the same just with different compositions.

        Except the old jaws. We gave up jaw muscles for more brainspace.

        Yeah ok you're right. They have 67% fast-twitch fibres according to https://www.pnas.org/doi/10.1073/pnas.1619071114
