Our patchwork origins – my new feature in New Scientist

The sequencing of the complete Neanderthals genome was one of the highlights of last year, not just because of the technical achievement involved, but because it confirmed something extraordinary about our own ancestry. It showed that everyone outside of Africa can trace around 1-4% of their genes to Neanderthals. Our ancestors must have bred with Neanderthals on their way out of Africa.

Then, later in the year, the same team revealed another ancient genome. This one belonged to a group of people called Denisovans, known only from a single finger bone and a tooth.
