Have you ever wondered why you feel a pull to go for that grueling trail run or long bike ride or demanding backcountry ski? We have an innate need for adventure, but why? According to paleoanthropologist and evolutionary biologist Ella Al-Shamahi, it’s in our DNA. Ella’s years of Paleolithic study focuses on the first humans and how they behaved—everything from community building to tool evolution to the world’s first sea crossing, which populated Australia. Her research has helped uncover a bonkers “Lord Of The Rings” era, when our foremothers and fathers existed alongside other human species that she calls things like “Hobbits” and “Dragon Men”…seriously. Ella believes that we have a genetic predisposition for adventure, which explains why homosapiens populated the earth and the Hobbits and Dragon Men did not. More importantly for our purposes, it helps explain why we still love to sleep in the dirt, climb mountains, and seek out the next big adventure.
