There's more to it than that. Aside from happening, the microchanges would have to happen in combinations which are simply prohibited by the laws of probability, and they would also have to spread through large populations of animals.
At that point, you get into the Haldane dilemma and other problems of population genetics. Even assuming macroevolution were possible which it isn't, the kinds of time spans which you would need to have our present biosphere from such a process would be, minimally in the quadrillions of years, and not millions or billions.
Yes, but the bottom line is you do believe in evolution, and do agree with Darwin on the topic.
It might help you comminicate if you realized that.
You're a Darwinist.
