David Reich’s Who we Are & How we Got Here. Important book on ancient DNA.

I will write a longer review, but this is a monument, not just a book. And the beginning of a new cultural program.

On a scale of 0 to 100, paternity tests count as 99.99 and written/oral history should count for .01. Apply that to populations. That’s plain statistics/probability. We are seeing science in action: information theory displaces BS, the handwaving just so stories we got from historians.
(A longer review to come).
