That's fascinating, or, well, it would be if I put stock in the validity of the various dating systems used.
You have to always keep in mind the ebb and flow of the ice sheets and glaciers in Europe and Western Asia at the time.
Modern Europeans made it to Europe 35000 years back, then by 20,000 years ago there was a glacial maximum. Everyone was driven into unglaciated areas called "refugia". They lived there or further South until 14,000 years ago when it all melted.
The next 8,000 years were just one thing after another until about 6,000 years ago when someone figured out how to use "pictures" to show relationships. By 5,000 years go that'd advanced to where "pictures" were reflecting spoken language ~ a great advance.
It's been all downhill since then let me tell you.
