In our unique genomes, every one of us carries the story of our species--births, deaths, disease, war, famine, migration, and a lot of sex. But those stories have always been locked away--until now. Who are our ancestors? Where did they come from? Geneticists have suddenly become historians, and the hard evidence in our DNA has blown the lid off what we thought we knew. Acclaimed science writer Adam Rutherford explains exactly how genomics is completely rewriting the human story--from 100,000 years ago to the present. A Brief History of Everyone Who Ever Lived will upend your thinking on Neanderthals, evolution, royalty, race, and even redheads. (For example, we now know that at least four human species once roamed the earth.) Plus, here is the remarkable, controversial story of how our genes made their way to the Americas--one that's still being written, as ever more of us have our DNA sequenced. Rutherford closes with "A Short Introduction to the Future of Humankind," filled with provocative questions that we're on the cusp of answering: Are we still in the grasp of natural selection? Are we evolving for better or worse? And... where do we go from here?

TL;DR; White people are genetically smarter than black people.
(To be transparent: I'm a white father to a black daughter... the book is bull shit IMHO)
That said: If you enjoy genetics, I'd recommend "A Brief History of Everyone Who Ever Lived", which uses actual science and is much more recent:

The author's style is entertaining and insightful, although a bit flowery. As a reviewer on Good Reads mentioned "That was very... British."
There are some phenotypes (characteristics) which clearly can be associated with a small number of genes (e.g. autosomal recessive disorders) , however for many phenotypes such as intelligence, it takes a lot more effort to correlate them with underlying genotypes. The fact that intelligence is approximately normally distributed is an indicator that there are many individual effects at play.
