SciShow: How Ancient Human Clues Ended Up in Rock

Teacher or professor: SciShow
Subject: Science
Content of the Lesson: A lot of what we know about ancient human civilizations comes from the things they leave behind. But sometimes, humans don’t live in places long enough to leave these clues. So, some researchers have turned to techniques outside traditional archaeology to find evidence of ancient humans. Hosted by: Michael Aranda SciShow has a spinoff podcast!
