Ancient DNA evidence reveals two unknown migrations from North to South America

An international research team has used genome-wide ancient DNA data to revise Central and South American history. Their analysis of DNA from 49 individuals spanning about 10,000 years in Belize, Brazil, the Central Andes, and southern South America has concluded that the majority of Central and South American ancestry arrived from at least three different streams of people entering from North America, all arising from one ancestral lineage of migrants who crossed the Bering Strait some time before 15,000 years ago.

Climate change likely caused migration, demise of ancient Indus Valley civilization

More than 4,000 years ago, the Harappa culture thrived in the Indus River Valley of what is now modern Pakistan and northwestern India, where they built sophisticated cities, invented sewage systems that predated ancient Rome’s, and engaged in long-distance trade with settlements in Mesopotamia. Yet by 1800 BCE, this advanced culture had abandoned their cities, moving instead to smaller villages in the Himalayan foothills. A new study from the Woods Hole Oceanographic Institution (WHOI) found evidence that climate change likely drove the Harappans to resettle far away from the floodplains of the Indus.
