More support for Evolution from other Disciplines

Interesting article on how Tectonics, the movements of the Earth's crust, may have played a role in human evolution! For the past 25 years or so it's been believed that changes in the environment in Africa may have been what caused our distant ancestors to evolve walking upright on two feet. This article discusses a possible hypothesis on how that could have happened.

I've said it many times, and I'll repeat it here. The evolution of life, as described in the Modern Synthesis is Evolution Theory, has found support across a wide variety of scientific disciplines and here is another example. Walking upright may have become a necessity to forage for food as climate change caused by tectonic earth shifts, turned lush jungle into dryer steppes and plains. There would have been an obvious survival advantage to be able to travel and forage in open areas. Fun stuff to read!
