The whole point of intelligence is the ability to learn. This might just be a case of an animal that already evolved to have intelligence learning and adapting.

The whole point of intelligence is the ability to learn. This might just be a case of an animal that already evolved to have intelligence learning and adapting. Orcas are social animals that communicate and and interact. So, they might show collective behavior and the ability to adapt as a group. And obviously we've been hunting them to extinction and generally harassing them in their own natural habitat; even imprisoning them. They'd be well excused to hold a few grudges. The good news is that they could adapt again if we respect them.
