Genomic insights into the origin of pre-historic populations in East Asia

Credit: © Kairi Aun | 123RF.com Diverse East Asians derive ancestry from a coastal expansion tens of thousands of years ago Researchers have long debated whether the peopling of East Asia by modern humans occurred mainly via a coastal or interior route. The answer is probably both. Indigenous Andaman islanders of the Bay of Bengal, Indigenous Tibetans, ancient Taiwanese, and ancient and modern Japanese all derive ancestry from a deep shared lineage that split from other East Asian lineages more than 40,000 years ago, says David Reich, co-senior author of the study, who is a Professor of Genetics and Human Evolutionary Biology at Harvard University and an Investigator of the Howard Hughes Medical Institute. The simplest way to explain this is if some of the earliest modern humans in East Asia spread along a coastal route linking southeast Asia, coastal China, and the Japanese Archipelago. In contrast, the 40,000 year old Tianyuan individual along with present-day and early Holo

Ancient DNA shines light on Caribbean prehistory

Stone Interchanges in the Bahama Archipelago: “Long Journey’s End” (© Merald Clark for SIBA) An international team of scientists reveals the genetic makeup of the people who lived in the Caribbean between about 400 and 3,100 years ago-at once settling several archaeologic and anthropologic debates, illuminating present-day ancestries and reaching startling conclusions about Indigenous population sizes when Caribbean cultures were devastated by European colonialism beginning in the 1490s. About 6,000 years ago, at the start of the Archaic Age, humans first settled in the islands of the Caribbean. These individuals lived in what is now the Bahamas, Cuba, the Dominican Republic, Haiti, Puerto Rico, Guadeloupe, St. Lucia, Curaçao and Venezuela. Three to four thousand years later, stone tools gave way to clay pottery and the Ceramic Age began. Another two millennia passed before Europeans sailed across the Atlantic and made first contact.

Credit: Kristen Grace/Florida Museum The history of the Caribbean s original islanders comes into sharper focus in a new Nature study that combines decades of archaeological work with advancements in genetic technology. An international team led by Harvard Medical School s David Reich analyzed the genomes of 263 individuals in the largest study of ancient human DNA in the Americas to date. The genetics trace two major migratory waves in the Caribbean by two distinct groups, thousands of years apart, revealing an archipelago settled by highly mobile people, with distant relatives often living on different islands.

Ancient DNA shines light on Caribbean history, prehistory

About 6,000 years ago, at the start of the Archaic Age, humans first settled in the islands of the Caribbean. Three thousand to four thousand years later, stone tools gave way to clay pottery and the Ceramic Age began. Another two millennia passed before Europeans sailed across the Atlantic and made first contact. Those who study and those who live in the region have long wondered: Where did these stone tool-using and clay-crafting populations come from? Were they related to each other? How many people lived in the Caribbean when the Spanish first arrived? How much, if any, ancestry can today’s Caribbean populations trace back to these precontact Indigenous groups?
