The largest human family tree ever created relives the history of our species

A new and formidable family tree for all of humanity attempts to summarize how all humans alive today relate to each other and to our ancient ancestors.

To build a family tree, or genealogy, researchers sifted through thousands of genome Sequences collected from both modern and ancient humans, as well as ancient relatives of humans, according to a new study published Thursday (February 24) in the journal. to know. These genomes came from 215 groups scattered around the world. Using a computer algorithm, the team revealed distinct patterns of hereditary Difference within these sequences, highlighting where they coincided and where they differed. Based on these patterns, the researchers drew theoretical lines of descent between the genomes and came up with an idea of ​​which genetic variants, or alleles, were likely carried by these people’s common ancestors.
