<!--QuoteBegin-->QUOTE<!--QuoteEBegin--><b>Rat genetics enlighten human migrations as far back as the Neolithic</b>
Iâm clearly digressing. Back to Aplinâs results,<b> he and his team identified six lineages that all originated in Asia â in India and the Himalayan region, Thailand, the Mekong Delta of Vietnam, Indonesiaâ¦.</b> These six lineages can be traced to four major episodes of global rat expansion, all associated with human migration or trade. <b>See, about 20,000 years ago, one lineage moved from western India to the Middle East and from there to Europe. </b>Apin hypothesizes that this expansion was probably associated with the growth of trade networks during the Neolithic and Bronze Ages . But I think Apin has his dates all mixed up, the Neolithic is thought to have sprung up about 11-8,000 years ago and Bronze Age around 5-4,000 years ago. His work then shows how the European established rat lineage then spread to Africa and the Americas with European explorers. The East Asian lineage, meanwhile, arrived in Micronesia, from Taiwan via Japan, the Philippines and Indonesia, about 3,500 years ago.<!--QuoteEnd--><!--QuoteEEnd-->
