| Standing on the rim of the Grand
Canyon, gazing across this giant wound in the Earth’s surface, a visitor might

Many millions of years ago the Colorado Plateau in the Grand Canyon area contained 10, 000 more feet of rock than it does today and was relatively level. The additional material consisted of some 14-layered formations of rock. In the Grand Canyon region these layers were largely worn away over the course of millions of years.

According to the two scientists, humans possess a number of anatomical features that make them surprisingly good runners. ’We are very confident that strong selection for running-which came at the expense of the historical ability to live in trees-was instrumental in the origin of the modern human body form,’ says Bramble, a biology professor at the University of Utah.
Traditional thinking up to now has been that the distinctive, upright body form of modern humans has come about as a result of the ability to walk, and that running is simply a by-product of walking. Furthermore, humans have usually been regarded as poor runners compared to s
