<p><b>The new Bible of population genetics: the science transforming our understanding of the past<br></b><br>We are living through a revolution in knowledge. Over the last twenty years, genetics has shed new light on the history of humanity. It allows us to analyze an individual''s genome, compare it with populations all over the world, then show its place in migrations across continents.<br><br>Here one of the scientists at the forefront of this research, biologist Llu¿Quintana-Murci, reveals how population genetics is transforming our understanding of who we are. Thanks to its many discoveries, we now know that Homo Sapiens freely mixed with other human species, including Neanderthals, which allowed them to adapt to new environments and survive disease. Studies also show that we have multiple genetic ancestors: our maternal ancestors lived in East Africa while our paternal ancestors came from South Africa. These cutting-edge findings will shape our future too, offering the key to me
