Roughly 200 pages into America Before. Went to Graham's talk at Logan Hall in London a week ago, got my copy signed! This is a very well-written book, but one thing struck me looking at the map with the Denisovan DNA "blobs" in the Andamans, New Guinea, Australia and South America - if you place Africa in the middle, you will see that it stands sort of halfway between the Americas and Australasia. Could the Denisovan signals in the Amazon be explained by direct migrations from Africa?
Looking at one of the "distance between two points" tools online, Sierra Leone in West Africa is only 3,000 kilometres from the Brazilian coast, much shorter than (say) New Guinea to Peru.
