PART OF OUR DNA MAY COME FROM A HUMAN LINEAGE WE’VE NEVER FOUND. 🧬👀 On Particles of Thought, Dr. Hannah Critchlow discusses research into ancient human genetics and the evidence scientists use to infer so-called “ghost lineages” — archaic populations whose genetic traces may survive even though we don’t have a matching fossil or reference genome. Researchers can use computational models to identify unusually divergent stretches of DNA and reconstruct ancient admixture events between human populations. Even more intriguing: some archaic genetic variants retained through evolution have been associated with functions involving the brain, immunity, and adaptation. So somewhere in humanity’s genetic history, there may be populations we know primarily through the DNA they left behind. What do you think we’ll discover first — their fossils or more of their genetic fingerprints? 🧬👇Scientists studying human evolution can detect evidence of ancient populations hidden within modern genomes — sometimes referred to as ghost populations or ghost lineages. Rather than identifying an unknown species from a fossil, researchers can infer previously unidentified ancestral populations through statistical analysis of genetic variation and ancient admixture. The research adds another layer to an increasingly complex picture of human evolution: our ancestry wasn’t necessarily a simple evolutionary tree, but a network of populations that separated, encountered one another, and sometimes interbred. 🎙️ Particles of Thought 🧬 Human Genetics • Evolution • Ancient DNA • Ghost Lineages • Neuroscience Save this one — human history may literally be written inside our DNA.#GhostDNA #HumanEvolution #HumanGenetics #AncientDNA #Genetics
