Dogs are closer genetically to each other than humans. Do we agree?

Yet no-one in their right mind would expect a boxer to able to perform like a collie.

In fact, collies do so well in standard tests of mental skill and athletics that it was necessary to create a competition that collies were specifically excluded from.

Because you see...er ummm well ...its because well er ...the collies are rayciss and stuff and the bulldogs suffer from discrimanashum and stuff

You really are a fool. Go away child.

Not 100% correct. Small genetic differences make a huge impact on phenotype. To dismiss them as irrelevant is nonsensical. The fundamental building blocks of DNA are so common in various life forms, that we share over 50% of our DNA with bananas. So please, lets drop the pretense that small variations are not important.

There is more genetic variation between members of SOME populations than between populations. BUT this in no way detracts from the fact that races can always be definitively identified from genome wide analyses of DNA. Patterns of variation conclusively identify a race (or even component races for mixed people).

Biologically determinant behaviors such as intelligence and social adaptability are a function of complex gene interactions of literally thousands of alleles (nucleotides) working together.

A number of studies on a genome wide basis have shown that the genes which factor in intelligence are DIFFERENT between the various geographic races. That alone is sufficient basis for racial division. And it makes sense, why would the races in each separate geographic region evolved identical brain structures? Why on earth would evolutionary pressures have stopped at the shoulders?

Conclusion: It has always made logical sense to divide humans into geographic races - both from a historical and modern scientific basis. The achievement of Europeans is unmatched.
A pedantic doctrine of arguing that races exist only in clines is pure political expediency.

A quote from the above trying to explain why the polygenic prediction of European genes didnt work for Africans.

"To provide context for this degree of attenuation, we identified three existing papers
that examined the predictive power in an African-ancestry sample of a polygenic score
constructed using weights from a European-ancestry GWAS."
