It's one of the biggest controversies in archaeology.
"we have shifted the timeline of the beginnings of cognitive humanness forward in time by hundreds of thousands, if not even one million years."The researchers brought 28 participants into the lab. Each one was given the raw materials they needed to accomplish a simple task: cutting a string to access a reward. Working by themselves, the participants had to figure out how to use the materials to make a tool capable of cutting the string.
The results of the experiment were stunning. During the four hours they had to work, all 28 of the research participants independently discovered toolmaking techniques that were used by the earliest toolmakers.e toolmaking techniques these individuals used were very much the same as the ones that would have been used over 2 million years ago. For now, we see this as strong proof of principle that one can re-innovate the techniques without having seen them," Snyder says.
"If I look at these results, I see a set of technologies that have been replicated by these individuals that do not match with what we find [in the archaeological record from] 2.6 million years ago," he says.
As the number of artifacts in the archaeological record has grown, archaeologists are increasingly turning to the number of various types of tools to understand ancient technology."The archaeological record is about numbers and frequencies. It's not about rare events," says. That's important here because the study participants didn't develop techniques in ratios that match what's found in the period of interest for the study authors.
"I think a lot of people would be quite happy to argue that, yeah, there's probably a lot of individual experimentation going on over 3 million years ago with hominins who are evenThe study authors disagree, writing"[a]bsent new lines of evidence, the earliest unequivocal evidence for technique transmission, and with it, cumulative culture of know-how, should be pushed forward to a later time.
