Default How did these species only end up 7000 miles apart at the poles?

They call this "new" science.

"A marine census released Monday documented 7,500 species in the Antarctic and 5,500 in the Arctic, including several hundred that researchers believe could be new to science.

In one of the biggest surprises, researchers said they discovered dozens of species common to both polar seas — separated by nearly 7,000 miles (11,000 kilometers). Now they have to figure out how they separated."

"So finding species at both ends of the Earth — some of which don't have a known connection in between — raises a whole bunch of evolutionary questions," he said."

Big surprise? ?

And they're going to call it "evolutionary"? ?
