PositiveThe Wall Street JournalMr. Zimmer, a New York Times science columnist and author, is careful and well-informed. So when he says that research is overturning things you were taught in biology classes, he’s worth heeding. Acquired traits can be inherited. Biological time can turn backward. And monsters are real ... You may also think that you’re just one person. But are you? ... We’re just another pervert. A smart one, but a copycat. We study viruses to learn how to hack cells. We study bacteria to learn how to edit chromosomes. We study gene drives to understand how to rig organisms to pass down the traits we want. Maybe we’ll learn to do these things more powerfully than our predecessors did. But nature has seen such tricks before.
