If the bones did come from the sandy layer, they might indeed have been eroded by the surrounding sediment, as animals walked overhead. When bones are trampled, they show two types of obvious marks: McPherron puts it like this. The age of those sediments helped him to work out how old the bones are, giving him an interval of 3. In the end, this is a matter of interpreting uncertain evidence and all the quirks that go into that. The specimens were all found on the surface, which makes it hard to know about where exactly they came from. They argue that similar cuts can be produced when bones are gnawed by animals, trampled into rough ground, or even eroded by plants and fungi.

In the end, this is a matter of interpreting uncertain evidence and all the quirks that go into that. McPherron puts it like this. Last year, Dominguez-Rodrigo showed that marks produced by genuine cutting tools can be easily distinguished from those produced by trampling. The debate revolves around when and how the marks were made. He argues that the Dikika marks — flat-bottomed and curvy — are much more likely to be the result of trampling. Gloves come off in bone mark debate By Ed Yong November 15, 3: Based on where the bones were found, and the fact that they had very little dirt sticking to them, McPherron thinks that they came from a nearby sand bed. They argue that similar cuts can be produced when bones are gnawed by animals, trampled into rough ground, or even eroded by plants and fungi. But these marks, recovered from Dikika, Ethiopia , have launched a controversial debate about nothing less than when human ancestors started using tools. The specimens were all found on the surface, which makes it hard to know about where exactly they came from. The timing also pushed back the earliest estimates of tool use in our family tree by , years. Furthermore, no one has ever tested unflaked stone tools in butchery experiments so no one really knows what type of marks they would produce. If the bones did come from the sandy layer, they might indeed have been eroded by the surrounding sediment, as animals walked overhead. The age of those sediments helped him to work out how old the bones are, giving him an interval of 3. Other researchers share his scepticism, including Sileshi Semaw, who discovered the Gona tools. His experiments revealed that the former have a V-shape in cross-section, with steep walls that meet at a pointed base. However, McPherron says that the marks were probably made by naturally occurring stones with broader and blunter edges. In this PNAS paper, three analysts who regularly work together two of which are holding their prior analysis up as the earliest stone took marks, and thus have a clear bias , reach a conclusion as a group. His criticism is based solely on the photos in the Nature paper. To them, the best evidence for butchery by human ancestors comes from stone tools recovered in Gona, Ethiopia, which are just 2. Dominguez-Rodrigo asserts that the Dikika team should have looked for other fossils from the same location to confirm the age of the bones. When bones are trampled, they show two types of obvious marks:
