Genetic memory
Genetic memory was the ability of one's DNA to carry memories of things an individual hadn't experienced. Some species relied solely on on genetic sequencing to to pass on their culture. Humans appeared to have a similar capacity to this. ()

The "Sky Spirits" inserted a genetic memory of their first encounter in 43,000 BC with a small group of nomadic Human hunters, which was meant to be one of their gifts to the hunters and their far distant descendants in the future.  They were able to do this through touch alone.  This strongly suggests that they themselves also have genetic memory. ()

In 2373, in an attempt to convince him that he was actually Taresian in origin, Lyris attributed Harry Kim's ability to know details about a planet he had never seen to dormant genetic memories which were re-awakened as he made his way there. ()
