Today on the program, we look into a project called Apps for Apes that uses iPads to provide mental stimulation for bored orangutans, and which is teaching researchers about the brains of our ape cousins. Plus, we'll find out how early humans cracked the craniums of hunted and scavenged animals for some real brain food; we'll learn how dogs and humans evolved together; and we'll hear how longhorn beetles can survive an Arctic winter. But first, ancient water runs deep.
