Scientists just cracked open 2-million-year-old tooth enamel from Paranthropus robustus (think: ancient, heavy-chewing human cousin) and found some wild surprises. Using protein analysis instead of DNA (which doesn’t survive well in Africa), they discovered both male and female fossils—and genetic quirks that hint at more diversity than anyone expected. Some individuals even had unique enamel genes, suggesting we might be looking at a whole mix of ancient relatives, not just one species. The human family tree just got way messier—and way more interesting! #Science #HumanEvolution #AncientDNA
