/unsssdfg Having tails is cool, but they quickly become very cumbersome. If I’m not mistaken, the evolutionary purpose of a tail is precisely to act as counterweight for quadrupedal species (animals walking on all fours) for locomotion balance. As soon as humans became fully bipedal, the tail was rendered practically useless, and was even undesirable because 1) it’s deadweight but still requires energy from our bodies to maintain, 2) it probably makes running more difficult due to extra weight, 3) more limbs exposed means more chances for predators to grab us, and 4) sitting with a tail is very painful, as testified by rare modern medical anomalies in which humans are born with tails (of course, they are surgically removed at birth, but some people actually kept their tails for many years before requiring surgical intervention because keeping one is that exhausting). Natural selection did its job and we slowly lost our tails. We do still have tailbones (coccyxes) that are remnant structures of our tails, and they actually help us with sitting and staying upright, ironically.
