Many writers claim that human kinds are significantly different from biological and natural kinds. Some suggest that humans kinds are unique because social structures are essential for the etiology of human kinds. Others argue that human cultural evolution is decidedly different from other forms of evolution. In this paper I suggest that the gulf between humans and our biological relatives is not as wide as some argue. There is a taxonomic difference between human and nonhuman organisms, but such factors as social structure and cultural evolution do not distinguish us from many other organisms.
