Could Neanderthal man walk among us again?

Harvard biologist George Church believes that enough of the DNA that comprised the Neanderthal genome has been recovered from fossils to make a stab at cloning a living specimen. He told a German newspaper that the process would mainly require "an extremely adventurous female human" to be a surrogate mother.

USA Today reported that Church said he was answering a hypothetical question and that he's "certainly not advocating" cloning Neanderthals in a subsequent interview with the Boston Herald.

Perhaps more daunting that the technical issues that would accompany the creation of Neanderthal clones are a long list of ethical and moral considerations.
