Take a look at this little video of a baby monkey. It's just three days old. Isn't it just adorable?
Oh, there's also this little bit about how the monkeys imitating humans is similar to earlier research on human babies, suggesting that it's a social adaptation that is common not to just humans, but also other primates. You can read all about it here, or in summaries on BrainEthics or John Hawkes.
But aren't the little monkeys cute?
