Harvard Professor George Church thinks that he will see a Neanderthal baby in his lifetime born of "an extremely adventurous female human", as he explained in an interview with Der Spiegel. He considers that this would be a good thing, as these ancient people might have genes which would strengthen genetic diversity. He overlooks the fact that modern humans already have Neanderthal genetic material.
The "extremely adventurous female human" is mentioned on pages 11 and 148 of Church's recent book, Regenesis: How Synthetic Biology Will Reinvent Nature and Ourselves.
