DNA From Two Octopus Species Just Revealed a Serious Warning About Global Climate Change

The Weddell Sea and the Ross Sea are separated by the West Antarctic Ice Sheet, one of the biggest in the world, covering some 530,000 cubic miles. That means that creatures on one side of the ice sheet should be as different as they would be from those in another ocean. However a recent DNA analysis of octopuses from each side has surprised scientists, as they appear to share a relatively recent common ancestor.
