Published by AnneH under genetics 101, news

About 10,000 years ago, the prehistoric hunter-gatherers of Europe began meeting some new neighbors.
These farmers spread gradually at first, expanding from the Near East through Anatolia and the Balkans. Then agriculture exploded, reaching present-day Britain within a few thousand years. The farmers settled into houses, which soon evolved into villages, towns and eventually cities.
The archaeological [...]

Recalibrating the Genetic Clock: Scientists Develop New and Improved Method for Timing Prehistoric Human Migrations Using Mitochondrial DNA

Published by AnneH under news

Just over 20 years ago, the first study using mitochondrial DNA (mtDNA) to trace prehistoric human migrations was published. In this seminal study, scientists managed to determine that all humans alive today can trace their maternal ancestry back to one woman who lived about 200,000 years ago in Africa. The findings were revolutionary, and [...]
