Sounds to me like it's exactly what Darwin said. The best traits of surviving (i.e. Not being delicious or full of meats) are the traits being passed on.

Well, that's the catch 22 for the fish. The exact things we see as helpful to the fish, we also see as delicious to the human. Fish (like salmon or trout) are almost all meat, with a very un-intrusive skeletal structure, VERY small amount of connective tissue and fat and they never work hard enough to make their meat gristly, unlike cows. Therefore, the best of their natural species are the best for humans to eat.

In cows, we have to raise them a certain way and treat and feed them correctly to ensure their tasty-ness. If I served you some wild longhorn cattle, you would not like it as well as farm-raised steak. But if I served you some wild salmon, you would like it as much, if not more than salmon from a hatchery.

So in fish, the best traits for the animal, are what we desire, and in cows, the best traits for the animal are not what we desire.

Check and mate.
