Family That Walks on All Fours


Episode Info

When scientist Uter Tan first discovered a rural Turkish family who walked on all fours back in 2005, the intense scientific debate that followed would erupt into a media sensation. Intrigued by Tan's theory that the family may in fact be "genetic throwbacks" who could provide a glimpse into our ancient human ancestry, German geneticist Stephen Mundlos embarked on a quest to uncover the genetic mutation that could have prompted early humans to stand upright. Yet despite this research, a number of prominent anthropologists and biologists have argued that the theories presented by Tan and Mundlos weren't just scientifically incorrect, but insulting as well. With this release the filmmakers at NOVA attempt to discern whether Tan's curious discovery is the anthropological revelation of the millennia or a mere medical anomaly.
