TL;DR: It is shown that Steppe ancestry then integrated further south in the first half of the second millennium BCE, contributing up to 30% of the ancestry of modern groups in South Asia, supporting the idea that the archaeologically documented dispersal of domesticates was accompanied by the spread of people from multiple centers of domestication.

TL;DR: In this paper, the authors report genome-wide data from 166 East Asian individuals dating to between 6000 and 1000 BC and 46 present-day groups, showing that hunter-gatherers from Japan, the Amur River Basin, and people of Neolithic and Iron Age Taiwan and the Tibetan Plateau are linked by a deeply splitting lineage that probably reflects a coastal migration during the Late Pleistocene epoch.

TL;DR: Ancient DNA has the potential to untangle patterns of movement and interaction underlying this economic and cultural transition, and complex spreads of herding and farming in eastern Africa involving multiple movements of ancestrally distinct peoples as well as gene flow among these groups are suggested.

TL;DR: In this article, the authors report genome-wide data from 174 individuals from The Bahamas, Haiti and the Dominican Republic (collectively, Hispaniola), Puerto Rico, Curacao and Venezuela, which they co-analysed with 89 previously published ancient individuals.

TL;DR: High mobility and inter-island connectivity throughout the Ceramic Age as reflected in relatives buried ~75 kilometers apart in Hispaniola and low genetic differentiation across many Caribbean islands, albeit with subtle population structure distinguishing the Bahamian islands from the rest of the Caribbean and from each other, and long-term population continuity in southeastern coastal Hispaniola differentiating this region from the remainder of the island.
