Simulations of hominin Lucy help show how long distance running evolved in modern humans
A team of natural scientists, musculoskeletal specialists, and evolutionary biologists affiliated with several institutions in the U.K., working with a colleague from the Netherlands, has found via simulations, that the famous ...
Extended chart of life shows ancient species may have evolved slower and lasted longer
If all the world's a stage and all the species merely players, then their exits and entrances can be found in the rock record. Fossilized skeletons and shells clearly show how evolution and extinction unfolded over the past ...
