I would say “race” is a social construct. Different cultures have different definitions of race at different times. “White” at this point in time is in flux. At one point in America all Caucasians were “white”. This is no longer true.
When I was a kid anyone even with minuscule “black” ancestry was black. Not true anymore either.
The British used to categorized southern Europeans, north Africans and Jews as non-white. It's why “Othello” is played by blacks now.

Most people categorize all sub-Saharan Africans as the same race. Genetics says there is more genetic diversity in Africa than in all the other regions of the world combined.

Also yes, it's a long standing critique (by geneticists) on Murray's work that he's been sloppy and confusing correlations with causations.

Murray would agree with every word you have written here. You need to read his book.
