The Greenland shark can live up to 500 years. The kind of longevity that probably has something to do with its home: cold, dark depths of the North Atlantic Ocean and Arctic Ocean.

Researchers from the University of Guelph in Canada have reported an astonishing discovery: that the number of chromosome sets in their bodies’ cells seems to be linked to the rate at which the species’ mitochondrial genome evolves. This is unusual because mitochondrial DNA sits in a separate genome from the chromosomes in the nucleus and…
