The researchers don’t know which ancient human species made the structure and the tools, but it’s unlikely to have been Homo sapiens. The earliest fossils of Homo sapiens found so far date from around 300,000 years ago and were found in Israel, Dull told CNN. He believes the people who made the structure were cognitively sophisticated and it would be very exciting to figure out who constructed this.
There’s some theories out there that Neanderthals were smarter than Homo Sapiens, but they didn’t form larger social structures. That’s part of our evolutionary advantage.
