Why don't people get to keep their tails from when we were monkeys and stuff???

Answer 1

Well, first, we weren't monkeys. Humans evolved from an ancestor common to primates, similar to the modern ape. Also, PEOPLE weren't monkeys (or apes). There was no point at which an ape just turned into a person or even a point at which an ape gave birth to a human. It took millions of years of imperceptible changes for humans to evolve.

Evolution tends to weed out traits that organisms don't need, and reinforces traits that they do. At some point, the ancestors of humans may have had tails. As pre-humans started spending more time on the ground (and not in trees), the tails would have been less useful. Since having a tail would give no real benefit, those born with a shorter tail wouldn't be at any disadvantage from those with longer tails. Over thousands of generations, tails just became shorter and shorter until they were no longer visible.

Humans actually still have tails, but they are vestigial. The bone structure is called the coccyx, and continues a tiny bit beyond the base of the spinal column (the sacrum). It is completely internal and we have no control over it, but is still useful, as it serves as an anchor for several muscles.

Answer 2

Answer 3

Tail -> monkey.

No tail -> ape.

Humans have NO TAIL, so humans are... ?

I will let you answer the question.

Answer 4

evolution. we didn't have a use for it, so it became obsolete. this is evident when you notice that everyone has a tail bone. it is a vestigial feature

Answer 5

Look on the bright side, we got opposable thumbs!

Answer 6

because we no longer need them i guess.
