A ridge of teeth discovered in a cave in Israel are between 177,000-194,000 years old, according to a paper published today in Science. The teeth appear to be human, and if they are, would be the oldest anatomically modern human fossil found outside of Africa and the oldest fossil with modern human traits found to date.
What it means: Fossils like these, and new gene sequencing tools, are starting to answer questions about when modern humans left Africa, and when, exactly, they became human. The find in Israel suggests modern humans may have left Africa earlier than previously thought. And, they didn’t just find a jaw — they unearthed sophisticated stone tools, too.
