Well, everybody’s looking for what propelled us from our common ancestor with chimps to the wonderful species we are today. If it’s not genes, it’s culture. Today’s NYT discusses Richard Wrangham’s new theory (previously mentioned on this website) about how the taming of fire and its use to cook food were crucial events in making our species what it is today. I am skeptical (I’ve seen many of these theories come and go), but still looking forward to reading Wrangham’s. new book, Catching Fire: How Cooking Made us Human.
