Refutes most of the claims made by Harari in Sapiens, and shows everything you though you knew about prehistory is plain wrong. It's a great book, very well written and well informed.
Made me think that humanity's history isn't an arrow pointing in the direction of progress; we make experiments. Our current way of life is not the "best so far", it's but one arrangement among many other possible configurations. The alternative between this and going back to living in caves is a false choice.
