From an evolutionary perspective, how did our species evolve to have derp sleep for long hours? I understand that sleeping conserves energy, but it would also make humans vulnerable to predators and not getting killed should take priority over saving energy
In: Biology
Have you gotten killed during your sleep?
Had your ancestors?
Sleep has numerous restorative benefits and it does not make one as vulnerable as you’d think (otherwise, all our ancestors would have been killed).
Especially not if you congregate and sleep near others, as humans tend to do.
