'"Most of the marks have features that indicate without doubt that they were inflicted by stone tools," explains Dr. Curtis Marean from the Institute of Human Origins at Arizona State University, who performed the mark identifications. "And the range of actions includes cutting and scraping for the removal of flesh,

This evidence that a precursor species, Australopithecus afarensis, to the first member of the human genus—Homo habilis—was eating bone marrow, is a game changer for understanding the development of this ancestral species.

Why? Because of the intense health benefits of consuming bone marrow.
