yeah, it's called selective breeding. we've been doing it for hundreds of years. It's not hard.

And when nature does the ‘selective breeding’, it is called “Natural Selection”.

So you admit that natural selection can change a population with favored traits becoming more predominant within the population due to differential reproductive success?

The difference being that there is no artificial intervention in the actual selection process, by means of those tanks. That is, to show there is no external “intelligent” designer behind the adaptations.

With dogs, the breeder specifically chooses the mating partners.
