Here is a very bright, very good academic from Stanford, Robert Sapolsky, giving a 'class day' lecture (skip the first 5 minutes of introduction):
This is an excellent lecture on how humans aren't really unique. Genetically we are very similar to other animals. Butwe are sufficiently different in our behaviours to make us 'unique'.
I love the moral that comes at the very end of this lecture. It is simply beautiful.
