Скачать или смотреть How One Gene Mutation Created Blonde Hair in Sweden

Why are Swedes so blonde? The answer lies hidden in a single gene mutation that changed human history forever.

In this documentary, we uncover the fascinating story of the KITLG gene mutation—the genetic switch that created blonde hair in Scandinavian populations. Through cutting-edge ancient DNA analysis and archaeological discoveries, we trace this remarkable evolutionary adaptation from the Ice Age to modern times.

🧬 What You'll Discover:
• The KITLG gene mutation and how it controls hair pigmentation
• Why Ice Age survival pressures favored lighter hair in Northern Europe
• Founder effects and genetic isolation in ancient Scandinavia
• Ancient DNA evidence from prehistoric Swedish populations
• Convergent evolution: Why Melanesian islanders also evolved blonde hair independently
• Viking expansion and how blonde genetics spread across Europe
• Medieval genetic continuity in Scandinavian populations
• Modern genomic research revealing the full story

This video explores the intersection of human evolution, population genetics, and cultural identity. We examine how environmental pressures during the last glacial period created selective advantages for depigmentation mutations, leading to the distinctive blonde phenotype associated with Scandinavian ancestry today.

From Neanderthal admixture to Denisovan DNA contributions, from ancient migrations to modern 23andMe results, this is the complete scientific story of blonde hair evolution—backed by peer-reviewed research and archaeological evidence.
