EARTH: Butchery or Trampling? Controversy Marks Ancient Animal Bones
FOR IMMEDIATE RELEASE

Alexandria, VA - As Americans feast for Thanksgiving, scientists are engaged in a debate over what human ancestors feasted on, and when it occurred. EARTH Magazine brings readers this active debate centered around fossilized animal bones and the marks that are on them.
Several years ago, scientists discovered 3.4-million-year-old animal bones near Dikika, Ethiopia, that had strange markings on them. Scientists initially reported that the markings were tool marks made by human ancestors who were butchering and eating the protein- and fat-rich animals. If true, the find would push back the active hunting and butchering of animals by 800,000 years in human evolutionary history. Other researchers, however, say that the markings formed when animal carcasses were trampled. Since then, debate has raged, with each study contradicting the previous one. Now, in yet a new study, researchers are using different methods to interpret the marks on bones and their findings indicate the animals were slaughtered by human ancestors for the original paleo diet.
