Church would modify a modern human genome so that its DNA matches the Neanderthal version. [...] this Neanderthal genome would not be inserted into a human cell but instead into a chimpanzee cell. This chimp cell would be reprogrammed to an embryonic state, and then introduced into a chimpanzee's womb where it would develop into a Neanderthal infant.
