Now, there's no way a three-inch-long freshwater cavefish can swim across the Indian Ocean, so what we found when we compared the DNA of these species is that they've been separated for more than 100 million years, or about the time that the southern continents were last together.
Det er ikke mulig at en 7 cm lang ferskvanns-hulefisk kan svømme tvers over Det indiske hav, så det vi fant når vi sammenlignet disse artenes DNA, er at de har vært separert i over 100 millioner år, eller rundt den tiden de sørlige kontinentene sist hang sammen.
