Summary:
Eight percent of your genome derives from retroviruses that inserted themselves into human sex cells millions of years ago. In a recent study, scientists discovered that 39 different koala retroviruses in a koala's genome were all endogenous, which means passed down to the koala from one parent or the other; one of the koala retroviruses was found in both parents.
