It is common scenically obvious that human races are real, & I don't just mean by skin color either. There's differences in body fate distribution,type of head hair(blacks have tight curly,hair,for example),height, and yes how much facial hair 1 man happens to have(Amerinds, for example either have very little or none at all.) with all those differences taken into account;how can 1 honestly believe human group differences just don't exist?
