Jamie and I have been Tivo-ing the PBS series, Becoming Human. It is awesome. It also awes and inspires me to see how smart people are; not just evolutionarily-speaking with all the fire- and tool-making, but the scientists who can piece together a life story that is millions of years old.
They can tell how many days old the homo erectus was when he died by looking at its teeth (apparently enamel on a tooth grows another layer according to the circadian rhythm), or that how many millions of years ago it was that humans became hairless (using what they know about the difference between head lice and pubic lice), and that homo erectus had developed enough socially to care for each other because they found a skull that had no teeth and had not had teeth for two years before it died showing that its "community members" had cared enough to feed him and even go so far as chew his food for him.
Oh, and we found water on the moon today.
Science -- just incredible.
