This is really possible, because pigs and people have too many uses, such as skin color, internal organs are basically the same, and chromosomes are similar! And there are fewer points close to the ape-man, but it can't be said that it has nothing to do with it! This should be the habit of people being sensitive to temperature and storing fat when they evolved from water to land. Together with using fire, they will build houses. My hair hasn't evolved! Of course, elephants, hippos, rhinos and other animals have not evolved hair! But their skins are thicker than humans! This kind of animal, mostly in the tropics, migrated to the north only after human beings had the wisdom to dress, so they didn't evolve the thick fur unique to northern animals! ! ! Because pigs are kept in captivity, their characteristics are the same and their internal organs are similar. It is possible to come down in one continuous line, but different habits have evolved into different directions! Led to the ending now! ! !
