Biology: Why do Dogs smile and Chimps Cry

Show on the Discovery channel.

In the 60’s and 70’s they did an experiement to teach a few chimps sign language. In the 80s one of them had a baby, and the baby learned sign language from its mother. How cool is that!

DNA wise, Chimps are closer to humans than Gorillas.

Wow, FEMA disaster search dogs. In the aftermath of the Oklahoma City bombing the search dogs would get bummed out at the end of the day of searching and only finding dead people. It would get to the point where the dogs didn’t want to work anymore. It got to the point where they would stage a successful find of someone so that the dogs could end the day on a good note.
