True. It seems that orcas evolved to live in family groups, and swim hundreds of miles hunting for food. Not an environment we can replicate in captivity.
I think the film said that most orcas in sea parks are now born in captivity. So if we keep this up for another 25,000 years or so, we may breed the wild instincts out of them. Just like we've domesticated dogs, chickens, cattle, etc.
The wild instincts have never been totally bred out of me!
