ELI5: Why are animals with slightly different genetic traits considered separate species but humans with slightly different genetic traits are not?

Definitely not implying that any group of people are more human than any other.

The general test is do they normally interbreed in the wild in a way that results in offspring that are health enough to breed in turn.  If they do, species, if not 2 species.

Human can all interbreed, so all the same species.  And our genetic diversity is shockingly small compared to most species dues or a fairly recent evolutionary bottleneck.  ONe of the reasons racism is stupid.

An average family group of chimps had more generic diversity than all of the human race.
