The Southern Levant has been a region of cultural importance throughout
ancient history. To learn about the genetic history and heritage of the
inhabitants of the region during the Bronze Age, we sequenced whole
genomes of 73 individuals, the majority of which are from 1800-1300 BCE
(middle-to-late Bronze Age). We combined these genomes with previously
published Bronze Age individuals to form a dataset covering eight
archaeological sites in Israel, Jordan, and Lebanon.
We used a combination of existing and new statistical methods to study
the ancestry of the ancient genomes and their relations to modern
groups, including an adaptation of ChromoPainter to pseudo-haploid data
that can take advantage of information in linked SNPs.
The Bronze Age Levant individuals showed close genetic affinities, and
were consistent with being a mixture of earlier local populations and
migrants from the north-east. Evidence suggested that migration was
still ongoing until the middle Bronze Age. We quantified the
contribution of the Bronze Age Levant groups to present-day
Middle-Eastern and Jewish populations, and found that it was over 50%
for most populations.
