Octopuses Descend from Antarctic Ancestor

Here is an interesting article about many octopuses have a common ancestor that lived near Antarctica 30 million years ago. It also talks a little about a modern octopus that still lives in the Antarctic as being the closest relative of the ancestor. It is believed that octopuses started around Antarctica and then dispersed around the world and evolved to what they are today when Antarctica started to become the ice continent it is today.
