yeah i thought that was really interesting, i love looking at human behaviour from a really simplistic, primal, survival point of view. largely i beliveve as a result of having watched david attenborough's life on earth series - it really change the way i think about things, reinforcing the fact that i believe there is a reason for everything -and that that statement doesn't necessarily have to carry spiritual connotations. when you think about it, in the grand scale of evolution, language, emotions and intelligence are relatively new things and we were built and designed for much simpler purposes.
