Unless the thing you unearthed from the 15 thousands year old underground piece of ice from the north pole is a microscopic parasite that take months to show any symptoms and turn you into a zombie to spread. Then your just patient zero and we're fucked as a specie.
nah biology discoveries are always like "we thought this lesser spotted derpy pig didn't have big enough spots. turns out it's a new species" or "this protein turns out to be less curly and more squiggly when the fruit flies are having a lot of sex"
