Ancient Human DNA Indicates Ghosts
The article focused on scientists discovering new evidence of two previously unknown lineages of ancient human ancestors, identified through the analysis of modern human genomes. The modern lineage interbred with Homo sapiens over 50,000 years ago in Africa, and about 0.5-1% of current human DNA derives from it. The older lineage dates back more than 1.8 million years and interbred with Denisovans over 200,000 years ago. The use of a new technique called "TRACE" helped reconstruct parts of the human family tree and uncover these unknown ancestors, opening new horizons for understanding our evolutionary past. It confirms that some human genes carry traces of mysterious ancestors who lived hundreds of thousands to over a million years ago, even though direct examples from their DNA have not yet been recovered.
