Walking on two legs, or bipedalism, immediately sets us apart form other apes. It frees our arms for using tools and weapons and is a key part of our evolutionary success. Scientists have put forward a few theories to explain how our upright gait evolved, but the 'savannah theory' is by far the…

It is often assumed that Alister Hardy’s and Elaine Morgan’s aquatic ape theory (AAT) suggests that more than 5 Ma (million years ago) there was a semi-aquatic…
At a vertebrate palaeontology workshop held in Maastricht in 1998, some colleagues and I sat in a bar, lamenting the fact that nobody cared about anatomy any more, and that funding bodies and academia in general were only interested in genetics. Given the poor to non-existent coverage that anatomy…
Thorpe and colleagues, publishing in the journal Science, have performed a study of orangutan movement that is turning the traditional view of the evolution of walking on its head.
The traditional view is that walking upright on the ground -- terrestrial bipedalism -- was preceded by a phase of…
I've just done some experimentation on this subject, and have come to the conclusion that pussy-cat teeth are a coadaptation that evolved in tandem with bipedal posture for the express purpose of ensuring that said bipedal mammals never have to clip their toenails again...
