Recent research has uncovered the existence of a previously unknown human lineage that thrived in the Sahara Desert when it was a lush, green environment approximately 7,000 years ago. This discovery, made possible through the analysis of ancient DNA from mummified remains, suggests that this isolated group contributed to the diverse genetic landscape of early humans in North Africa. The findings indicate that the Sahara, often depicted as a barren desert, once supported a vibrant ecosystem that was home to a surprisingly unique population of humans. These insights have the potential to significantly reshape our understanding of human evolution and migration patterns in this region.
