At the end of 2018 this article provides recap of major insights produced or suggested from labwork on samples of ancient human remains.
One author, David Reich, has compared the powers of this new technology to the breakthroughs offered by Carbon 14 dating of organic materials excavated. Instead of induction and deduction from the layering of deposited materials to estimate dates, now some precision was possible. In the same way, DNA offers a sharper view of relatedness of peoples ancient and modern; it allows previous conclusions about (paleo) archaeological locations to be revisited, too.
Reich's 2018 book, Who We Are and How We Got Here, offers chapter by chapter visions of the past in various corners of the world.
