Jesús Rodríguez, Ana Mateos and Guillermo Zorrilla, scientists at the Centro Nacional de Investigación sobre la Evolución Humana (CENIEH), have just published a study in the Journal of Human Evolution in which they analyze the cannibalistic behavior of populations at Atapuerca 1 million years ago. The results make it clear that anthropophagy was a profitable strategy for Homo antecessor.
