They may be polar opposites, but something is attracting two species of minke whales, producing at least one hybrid offspring, a new study says.
A cross between an Antarctic minke whale and a northern minke whale was recently discovered during a DNA analysis of whales caught by Norwegian hunters.
Geneticist Kevin Glover was recently analyzing whale DNA when he came across a surprise—a whale hunted in the northeastern Atlantic in 2007 had the genetic blueprint of a hybrid, with an Antarctic minke mother.
The two species of whale from two different equatorial hemispheres (Northern and Antartic Whale) having created a hybrid seems to cause much more concern to me though.

There is also a hybrid bear as well.

I think it is a survival instinct based on the caps melting.
Some scientists believe that global warming could cause the hybridization of many arctic animals, particularly marine mammals. The thinking goes that as Arctic sea ice melts, closely related species in the North Pacific and North Atlantic will come into contact and interbreed. In the case of polar bears, loss of habitat could drive them to land, where they may come into contact with grizzlies. Other scientists, however, aren't convinced that climate change is the trigger for the hybrid bears. Changes in sea ice have been less drastic in the Beaufort Sea than in other parts of the arctic, and it seems quite possible that the pizzlies resulted from breeding pairs that met on ice, rather than on land.

I have to ask, what does this mean? And what are some of your concerns?
Climate flip-flop? That would be something...

Are these hybrids able to reproduce? I always thought they were born sterile.
