english: So even if I have a cell culture that I pass to my PhD students, who pass it to their PhD students, and so on, we'd have to do that for thousands of years in order to mimic the exact conditions of the deep subsurface, all without growing any contaminants.
non_english: Čak i da imam ćelijsku kulturu koju prenosim na svoje studente, koji prenose na svoje studente, itd, morali bismo to da radimo hiljadama godina kako bismo oponašali iste uslove duboko ispod površine, sve bez uzgajanja kontaminanata.
