Neanderthal DNA is 99.7% identical to our own, and researchers claim that some humans might be carrying as much as 2% of the Neanderthal genome. Making things even weirder is that scientists recently recovered a nearly complete DNA sequence from a 50,000-year-old Neanderthal skeleton. So in theory, Neanderthals could make a comeback. But how would they adapt? And how long would they survive?

But without it, we go nowhere." — Carl Sagan Produced by Underknown in Toronto, What If is a mini-documentary web series that takes you on an epic journey through hypothetical worlds and possibilities. Join us on an imaginary adventure — grounded in scientific theory — through time, space and chance, as we ask what if some of the most fundamental aspects of our existence were different.
