We have already established they eat based on what is available but what hasn't been established is why they have specific choices when there are more choices that don't appear to be personal choice.
My points all still stand. What you have said proves absolutely nothing and you are just regurgitating the same exact thing you already said. You didn't respond to anything I said, and you are making things up again. I'm not wasting my time. This has already been discussed to death. Personal choice? They don't choose to be hungry. They get hungry and then eat what they can eat at the time. I can't believe you having so much difficulty with one of the most basic concepts in the history of planet earth.
If you were right there would be evidence of it in the listings of diets about animals. They would say they just eat what ever, but they don't, they eat specific food and your ignorant to the truth. If you were right, cows would eat dogs, and lions would eat trees and bears would eat rocks, but your not, because they don't. They have an order, and order that has direction, and that direction is strong enough to remove personal differences when they are available. This order is only possible through the idea of intelligence, something intelligent has programmed them, before they were born, with knowing what their food is suppose to be.
If I'm wrong then you are basically making the claim that while humans need labratorys and test equipment to identify what food is needed for a species, animals just have it built in. Ya right.
