Oldest Human Genomes Reveal How a Small Group Burst Out of Africa
Briefly

Researchers revealed the genomes of seven individuals from the LRJ culture, the oldest genetic specimens of modern humans found, highlighting their pivotal role in early human expansion from Africa.
The LRJ people, living around 45,000 years ago, were shown to have long stretches of Neanderthal DNA, suggesting a complex ancestry interwoven with that of earlier human populations.
This new understanding implies that older sites occupied by modern human remains may have been inhabited by earlier waves of humans that didn't contribute genetically to today's populations.
The data indicates that the common ancestors of today's non-Africans lived approximately 47,000 years ago, raising questions about previous models of human migration.
