It seems like something out of a movie (and hey, it is), but there's some scientific evidence that we actually carry the memories of our ancestors with us in our genetic code. Apologies in advance to my hypothetical descendants.
The theory was especially popular in the 1960s and '70s, when scientists were just beginning to unravel the mysteries of the double helix. Our DNA determines our physical appearance, the reasoning goes, and our predispositions to various illnesses, and plays a role in our general disposition and skill set. All of that has been passed down to us through countless generations. So why not memories?
It sounds far-fetched, but there are still vast swaths of genetic code whose purpose is unknown. And the evolutionary advantages of having memories passed down - even one as simple as "FIRE BAD" - are overwhelmingly clear. Will we be able to tap into those memories any time soon? Probably not. But one day some generation might. And when they do, they'll see exactly how that great-great-great-grandpa Brian spent all his spare time on cheese snacks and '90s sitcom reruns. [American Chronicle]
