Largest Human Family Tree Identifies Nearly 27 Million Ancestors

Researchers create massive genealogical network dating back 100,000 years.

Researchers using modern and ancient genomes have created the largest human family tree ever made, reports Jack Guy of CNN.

An international team of scientists combined genetic reports of 3,609 individual genome sequences from 215 populations around the globe to produce a massive family tree that identifies nearly 27 million ancestors and where they lived, per U.S. News and World Report.

“We have a single genealogy that traces the ancestry of all of humanity and shows how we’re all related to each other today,” Anthony Wilder Wohns, leader of a new study published in the journal Science, tells CNN.

Wohns, a postdoctoral researcher at the Broad Institute of MIT and Harvard University in Cambridge, Mass., states the study uses ancient genomes from samples dating from more than 100,000 years ago.

“We can then estimate when and where these ancestors lived,” he says in a statement. “The power of our approach is that it makes very few assumptions about the underlying data and can also include both modern and ancient DNA samples.”
