Ana Mateos and Jesús Rodríguez, scientists at the Centro Nacional de Investigación sobre la Evolución Humana (CENIEH), have published an experimental energy study in the American Journal of Biological Anthropology, which shows that children and adolescents can walk at a speed close to the optimal pace for adults, with hardly any locomotion energy costs or departing from their own optimal speed. These results suggest that individuals at these ages do not represent a burden for the mobility of hunter-gatherer groups.
