Those are not identical looking at all and the DNA changes are significant
>Only two taxa (CELT and TRIGO) have minimum COI divergences (3.4% and 5.4%) from all other members of the complex that exceed the sequence threshold (3%) typically encountered between congeneric species pairs recognized by morphological approaches (14). Divergences among the remaining taxa are lower, but all exceed 1.1%, which is well above usual intraspecific values, except among members of the triad FABOV, HIHAMP, and INGCUP, which show <0.5% divergence.

By your argument humans and chimps are the same species.

Dogs don't occupy an ecological niche, only the one given to them by humans. Once that is gone the breed dog will either be forced into another or cease to exist, like the turnspit dog
>>12507674
Chimps and pre-industrial humans occupy different ecological niches.

chimps and humans have different numbers of chromosomes.

they don't have one (a niche), except for the one they have?
is this an argument that what humans do/have done is not natural?

No, you don't understand, niches are always referred to in a natural sense other wise a job would be classified as an ecological niche.

so it does hinge on the meaning of 'natural'
give me a link to a textbook or something that can clear this up for me.

they are an aberration w/in a speices
chimp 48 vs human 46 isn't aberrant
if you think downies are the next step, good for you, advance that theory, you might become famous!
