today's science:

> humans have no subspecies
> humans have no race
> humans have no varieties

also science:

> human is animal

So why the hell do these taxonomic classifications not apply to us like animals? There are animals without a subspecies like the hyacinth macaw, but this one, unlike us, does not have a genetic or morphological variety, this is not our case, nor does the term breed used in domestic animals belonging to the same subspecies apply to us.

So if we have no variety, no race, no subspecies, how does science explain our genetic and morphological differences?
