The research, a collaboration between the University of Roehampton, the University of Cambridge and several other institutions, combined archeological data with palaeoclimatic reconstructions to show for the first time that climate dramatically impacted the migration of people across Europe, causing a dramatic slowdown between 6,100 BCE and 4,500 BCE.
The research team, including Dr. Lia Betti, Senior Lecturer of the University of Roehampton, assembled a large database of the first arrival dates of Neolithic farmers across the continent and studied the speed of their migration in relation to climatic reconstructions of the time. They also re-analysed ancient DNA data to understand the interaction between early farmers and local hunter-gatherers.
They discovered migration started quickly out of south-eastern Europe, with Neolithic farmers pushing out the existing hunter-gatherer population. This was demonstrated by how little the DNA of the two groups mixed. As they moved north, the climate became less suitable for the crops they had bought with them. Their pace of movement slowed, changing how they interacted with local hunter-gatherers, which can be seen through increased genetic admixture of the two groups...
Comparing ancient DNA data from local hunter-gatherers and early farmers, the authors also demonstrated that the challenging climatic conditions for farming in Northern Europe led to closer relationships between the two groups and higher admixture. Exchanges of goods and local hunting knowledge may have allowed the first farmers to persist in these regions despite poor crop yields.
This research shows how climate has significantly impacted the migration of people since the beginning of our history. The climatic suitability of places to live and settle played a key role in determining where different human groups could thrive, in turn changing the genetics of entire continents.

Huh? Climate has changed before? I’ve been told it’s a recent phenomenon due to using fossil fuels. What a fool I’ve been. Does this mean the Polar Bears are going to survive?
The keyword listing gets its source viewed, highlighted, copied into a file, and processed by some painstakingly boring BASIC programs, then part of the output gets run through a low-rent database for chrono sorting, then *that* gets plastered back into the original file, followed by the other output files. Most of the work, IOW, goes on while I continue to surf. :^) Takes just a few minutes.
I wonder how much money it cost these clowns to discover that farming cultures would migrate to more suitable climates for better yield?

Yeah, lame, sounds like it was really easy research as well.
Thanks, not that it made any sense to me.
My pleasure. And thanks 31R1O! It's nice when someone says so, particularly in a rather benign topic where so many have been, are, and no doubt will continue to be gratuitously negative. :^)
That reminds me, please pass the polar bear stew.
Well, Duh.
Polar bear Stu is off my menu, I won’t eat anything I know by name...
My late father's description of the drought in the 1930s, right here in Michigan, made me realize that the drought I witnessed in the 1980s was merely an inconvenience where some curbside trees died along streets in Grand Rapids. :^) That was the year I started my long streak of swimming in Lake Michigan -- the water stayed above 80° for months.
It's 100° (not the Lake, the air) today, and while I love the hot weather, I won't be going through another summer without a pool in the backyard.
I called it.
This isn't too related, but at the cannibal restaurant (it's in another country) they serve Spaghetti and Pete's Balls. And for dessert, lady fingers.
When something changes around here I sometimes need to go back and figure out what I'd been doing with the program, and then it also makes little sense to me. :^)
One young patron was heard to say “I hate my sister’s guts!”
His mother admonished him to be quite and eat what was put before him...
They should never have been driving SUVs, I’m telling ya.
Just proves we aren’t the first “modern” humans to inhabit the planet. Those guys had evil fossil burning vehicles too. And, just like we’re doing now they destroyed the planet way back then. We now have the proof.
Here's a "reality TV" idea -- a families-change-places show where the families are the Flintstones and the Jetsons.
That's not the same things as saying that this was the first time that climate change affected human migration. There were people ("anatomically modern humans" as well as Neanderthals) living in parts of Europe before the Last Glacial Maximum, in places which were later under ice caps, so all the people left until the glaciers melted.
I simply read “BCE” as : Before Christian Era, and move right along.
