Scientists just found a single amino acid difference in a DNA-making protein between us and Neanderthals—and it might explain why we’re still here and they’re not. Mice with the human version of this gene acted differently, especially the females. The catch? It’s way too soon to say this is the magic answer, but it’s wild to think one tiny tweak could’ve given us an edge. Evolution is full of surprises! #History #Neanderthal #Genetics
