Research Study to Understand Why Man Learned to Walk
Michael Sockol of the University of California, Davis and David Raichlen of the University of Arizona trained five chimpanzees to walk on treadmills in a study they say shows that early humans began walking upright (i.e. bipedalism) because it saves energy.
The issue of how, when, and why early man began to walk upright has intrigued scientists since the age of Darwin. By pinpointing when man’s ancestors became bipedal, scientists will be closer to determining the human lineage.
