How One Migration Split Italian Genetics in Two #history #genetics

[00:00:00]Then, about 8,000 years ago, everything changed. A revolution swept from the Near East. It wasn't an army, it was an idea.

[00:00:09]It was farming. People from Anatolia, or modern-day Turkey, had figured out agriculture, and they expanded west, bringing their crops, their animals, and their DNA with them.

[00:00:20]They traveled by sea, and their genetic impact was huge in southern Italy, which became a gateway for farming to spread into Europe. Even today, southern Italian DNA shows a strong connection to the genomes of these Anatolian farmers.

[00:00:36]The north, though, was a different story.

[00:00:38]Farming arrived there, too, but the genetic influence from Anatolia was way less direct.

[00:00:44]Northern populations kept a much stronger link to the older, pre-farming hunter-gatherer groups. This created a clear genetic gradient across the peninsula, a north-south divide that was set in stone thousands of years before the Roman Empire, and is still the defining feature of Italian genetics.
