Darwin and DNA
Dec. 30th, 2009 11:41 amWhile I was honking gooselike into tissues and nursing great steaming mugs of tea last night, I caught the NOVA program called What Darwin Never Knew. In a nutshell, what Darwin didn't know about was DNA: what it is, what it does and how it plays a role in the evolutionary diversity of life on earth. Well worth a look the next time you're cruising PBS.
