And Slartibartfast's signature in the Fjord? I think that it's best to think of our pre-history as waaay more complex than the silhouette of evolution picture leads us to. We almost certainly shared land with other apes as different dogs share parks today, but beyond that it does not fit it in my head. I feel this is an area of science that is fascinating but ultimately, like study of butterflies - yes it's science, yes we fund it, but the value to billions of humans will likely come from other branches of science.

The lessons I need for today's living I can take more usefully from today, than hoping to extrapolate from a million year old bones.
