Forget dinosaurs. And no-one is moving any goalposts. We’ve just gor some chickens on an island. They make their nest on the ground, on dead braches on the ground and on low level branches. It makes no difference because there are no predators to worry about.
When the dogs arrive, the chooks that can reach the low level branches last longer than those that can"t. So there is a genetic tendency for the ability to reach low level brancbes to increase. Because those that can’t are taken out of the gene pool.
And then we have the arms race.
Reasonable? I have to say that there is nothing I have said that amounts to any kind of evolution, yet alone macro evolution, and nothing that denies the existence of God. This is all quite straight forward and happens in nature constantly.
