    Humans settled the Caribbean ~6,000 years ago, with ceramic use and intensified agriculture marking a shift from the Archaic to the Ceramic Age ~2,500 years ago. We report genome-wide data from 174 individuals from The Bahamas, Hispaniola, Puerto Rico, Curaçao, and Venezuela co-analyzed with published data. Archaic Age Caribbean people derive from a deeply divergent population closest to Central and northern South Americans; contrary to previous work, we find no support for ancestry contributed by a population related to North Americans. Archaic lineages were >98% replaced by a genetically homogeneous ceramic-using population related to Arawak-speakers from northeast South America who moved through the Lesser Antilles and into the Greater Antilles at least 1,700 years ago, introducing ancestry that is still present. Ancient Caribbean people avoided close kin unions despite limited mate pools reflecting small effective population sizes which we estimate to be a minimum of Ne=500-1500 and a maximum of Ne=1530-8150 on the combined islands of Puerto Rico and Hispaniola in the dozens of generations before the analyzed individuals lived. Census sizes are unlikely to be more than ten-fold larger than effective population sizes, so previous estimates of hundreds of thousands of people are too large. Confirming a small, interconnected Ceramic Age population, we detect 19 pairs of cross-island cousins, close relatives ~75 kilometers apart in Hispaniola, and low genetic differentiation across islands. Genetic continuity across transitions in pottery styles reveals that cultural changes during the Ceramic Age were not driven by migration of genetically-differentiated groups from the mainland but instead reflected interactions within an interconnected Caribbean world.

    Present-day people from England and Wales harbour more ancestry derived from Early European Farmers (EEF) than people of the Early Bronze Age1. To understand this, we generated genome-wide data from 793 individuals, increasing data from the Middle to Late Bronze and Iron Age in Britain by 12-fold, and Western and Central Europe by 3.5-fold. Between 1000-875 BCE, EEF ancestry increased in southern Britain (England and Wales) but not northern Britain (Scotland) due to incorporation of migrants who arrived at this time and over previous centuries, and who were genetically most similar to ancient individuals from France. These migrants contributed about half the ancestry of Iron Age people of England and Wales, thereby creating a plausible vector for the spread of early Celtic languages into Britain. These patterns are part of a broader trend of EEF ancestry becoming more similar across Central and Western Europe in the Middle to Late Bronze Age, coincident with archaeological evidence of intensified cultural exchange2-6. There was comparatively less gene flow from continental Europe during the Iron Age, and Britain’s independent genetic trajectory is also reflected in the rise of the allele conferring lactase persistence to ~50% by this time compared to ~7% in Central Europe where it rose rapidly in frequency only a millennium later. This suggests that dairy products were used in qualitatively different ways in Britain and in Central Europe over this period.
