🦋 fabulous things i know about nature. 19/? #amazingNatur 🦋
Palmaris longus is a muscle in the forearm. it is vestigial, we don't need it. but there is no evolutionary pressure either way, so some have it some don't.
i have it in the left arm and not in the right. i'm basically an atavistic bipedal ape with morton's toe and a monkey tendon.
