Unraveling Human History Through Lice: Insights from DNA and Migration

A genetic analysis of lice suggests that they arrived in the Americas twice - once during the initial human migration across the Bering Strait and again during European colonization. The study reveals two distinct clusters of lice, with a unique group in the Americas resulting from a mixture of lice descended from the First People and European lice. The research also supports the idea that people from East Asia migrated to North America and became the first Native Americans. The study highlights the coevolutionary history between humans and lice and provides insights into human migration patterns.
