Remember that weird skull found in a Greek cave back in the '60s? Scientists have been arguing for decades about what it actually is. Turns out, new research says it’s a super rare human species called Homo heidelbergensis—NOT a modern human or Neanderthal. And get this: it’s at least 277,000 years old! This could totally change what we know about human evolution. Wild, right? #Science #Archaeology #HumanEvolution
