The human body has not evolved perfectly, so why do you say that? See below:
1, the human neck can not be like many animals (such as red-crowned cranes, giraffes) like the rotation, so that humans can not see their backs, can not find the danger in time.
2, people lose their tails, but also lose the possibility of becoming aquatic animals, if human technology can not support human survival in outer space, in case the global land is submerged, people can only go extinct.
3, the human arm bone is not 4 knots, some movements can not be completed, resulting in dancing is not good-looking, the human arm is not long enough, can not scratch the entire back.
4, the human body will produce diseases that kill themselves.
This is really a puzzling question, if the human body is going to kill itself, why does the body have to evolve? If you want to evolve, why produce diseases that kill you? Why not strengthen immunity, so that their own body can not produce diseases, so that foreign viruses, bacteria, fungi can not infect the human body, threatening human life.
5, the human body can not be like earthworms, planarians or even salamanders, lizards can be broken and can grow back into the body.
6, people sleep for too long, people should only sleep 1-3 hours a night is enough.
7, people's ears, noses, people can not stop growing, if human beings can live forever, think about it is terrible!
