Yes, it does. The most interesting aspect it brings are numbers. It allows to measure how much of our DNA comes from which group of humans (Neanderthals, Denisovarians, etc). It also shows that the migratory currents had a lot of details that we barely got to understand. To understand Dr. Paabo's (and others) work, I suggested above "Who We Are and How We Got Here" by David Reich. Read it. It is easy reading. If you liked Sapiens I guarantee you will like that book too.
