Killer Whales Are Evolving Into Two Different Species
Scientists have found that Killer Whales in the North Atlantic Ocean differ in both diet and genetic makeup. In fact, they’re in the process of splitting into two different species all together.
Researchers examined the teeth of 62 whale skeletons, some that were hundreds of years old. They found that “type 1″ whales had longer teeth with significant wear in comparison to “type 2.” Type 2 whales fed on a combination of seals and fish. But type 1 whales stuck to dolphins and smaller whales, like that of Antarctic orcas.
