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.
Can you explain why that would be concerning though? I would celebrate that richness of history.
Mostly because we’ve been studying H. Sapiens for a long time so being so wrong would suggest a big gap in a dating methodology and the way we’ve tracked human migration of their history.
