The nonegenarian and I squeeze in one walk in a brief almost not-raining spell, and then indoor exercises to work out further restlessness. Fantastic "Nature" show on our human ancestors continued this evening; it's called "On Becoming Human", and it fascinates me. Not sure why, since I am pretty much convinced evolution has stopped and many humans are slipping backwards, but there is marvelous information coming out in this program. One show-stopper: They used a "molecular clock" to determine when human ancestors' pubic lice differentiated from gorilla lice. Researchers were trying to figure out when pre-humans became relatively hairless, so figuring out when they developed two kinds of lice, hair and body varieties, was a key time period. You gotta watch it to believe it...
