Lucy used tools, ate meat

Cut marks on hoofed animals rib, 3.2 - 3.4 million years agoResearchers studying fossilized animal bones from the Dikika region of Ethiopia have found evidence that Lucy’s species, Australopithecus afarensis, used tools to butcher meat. The bones had marks from cuts, scrapes and scratches made when the bones were fresh. Forensic analysis found stone fragments in one of the cuts.

Before this study, paleontologists thought hominids of the Homo species first used tools 2.5 million years ago, but the A. afarensis bones date to 3.2 million and 3.4 million years ago. Lucy and her kin were also previously thought to have eaten a vegetarian diet, but if they were butchering animals to the bone, they were eating the proceeds.

Study co-author Zeresenay Alemseged, the palaeoanthropologist from the California Academy of Sciences in San Francisco who leads a large research effort in the region, said that the find overturns much of what was thought about A. afarensis.

“For 30 years, no-one has been able to put stone tools in their hands, and we’ve done that for the first time,” he told BBC News.

“We are showing for the first time that stone tool use is not unique to Homo or Homo-related species – we have A. afarensis now behaving like Homo in a way both by using tools and eating meat. It’s another attribute that could enable us to link A. afarensis to the genus Homo.”

There are still some holes that need filling in, though. The sample of bones was small and no tools were found on the site. We don’t know if A. afarensis picked up convenient stones to use as tools, or if they were advanced to the point of actually crafting cutting tools out of larger stones.

We don’t even really have direct evidence that it was Lucy’s species doing the butchering. The bones were dated by dating the volcanic rock in the area where they were found, and it’s the date that points to A. afarensis because as far as we know there were no other hominid species in the Dikika region 3.2 – 3.4 million years ago.

If this pans out, that’s huge!

It really is. Tools used almost a million years before we thought. :eek:

I speak for everyone fortunate enough to be one
of the lucky people who subscribe to this blog
and who are privy to one helluva writer and the myriad topics he chooses to write about.

Not only does he ‘write’ but he exposes us, the reader, to a view of his expansive knowledge and worldliness and takes us along for quite the ride! If I can read his stories I can travel along with him, see some of the magnificent sights that this man has seen and for a time, I can soar through the ages of times gone by.

Times I so want to know about and learn about and see.

Thank you from the top and bottom of all our collective souls, Edward, thank you! :notworthy:

Thank you for your kind words, but I’m not actually Edward Goldberg, although I surely would love to inject his brain into my skull even just for a day or two.
