A new study analyzing ancient DNA has revealed that Bronze Age Britain underwent a dramatic population shift, with a large-scale migration from continental Europe fundamentally altering the genetic makeup of the island. Researchers found that around 90% of the ancestry of people living in Britain during the Bronze Age came from migrants who arrived from the continent, bringing with them new technologies, practices, and potentially even languages.
Geneticist David Reich explains how analyses made possible by technological advances show human history to be one of mixing, movement, and displacement.
A study combining archaeology and genetics, published in Science, reveals that the spread of Neolithic practices from Anatolia wasn't solely due to migration. Researchers found evidence of significant genetic continuity in West Anatolia over 7,000 years, despite cultural shifts like the adoption of agriculture and settled lifestyles. This suggests ideas and technologies spread without large-scale population movement in many areas. Some regions did experience migration and genetic mixing around 7,000 BCE, and later in the Aegean, but the overall picture is one of cultural diffusion occurring alongside, and often independently of, population shifts. The study highlights the importance of supporting research in the regions directly related to the questions being investigated and demonstrates a new methodology for integrating genomic and archaeological data.
