George Church is a molecular geneticist who teaches at both Harvard and MIT. He recently made headlines when he told the German magazine Der Spiegel that it's possible that he could see the birth of a Neanderthal baby within his lifetime. What's on display here, folks, is scientism, which posits that science alone can "yield true knowledge about man and society." If Neanderthals make a comeback - Church understates the difficulty of such an endeavor - it will happen because we can, not because we should.
