Okay, this is wild: Scientists just found 300,000-year-old teeth in China that show ancient humans were mixing and mingling way earlier than we thought. These teeth have a mashup of features from both Homo sapiens and Homo erectus—like a real-life evolutionary remix! Turns out, our family tree is way messier (and juicier) than those neat diagrams in textbooks. Human evolution? Total experiment zone. Mind blown! #Science #HumanEvolution #Archaeology
