double helix 43 millennia before we did. Of course, this image
doesn't actually depict DNA - archaeologists currently believe
these are meant to be the seals that the locals ate for food,
which you can see more clearly in the image below - but its
resemblance to the double helix means it should serve as the
perfect grist for either your next sci-fi short story or

Sanchidrián of Spain's University of Cordoba, charcoal found
right next to the paintings date to between 43,500 and 42,300

paintings themselves confirms that timeframe, then not only will
