Mindless evolution?

Not all evolution is mindless may I point out. Evolution simply means, change in a population. Humans have changed many things...dogs, cats, birds, etc. directly and quite conciously. We have changed many things unconciously...roaches, bacteria, virus populations....through our medicines and poisons. We killed the ones or prevented their breeding but a few always remain that reproduce, making stronger and stronger lines. The evidence is still not visible and immediately reproducible to say the law of evolution (such as the law of gravity which is theory of gravity when talking about what makes it so) but pretty clear.
Mindless does not mean lacking greatness. The mindless flow of rivers and glaciers have made the Grand Canyon and Great Lakes respectivley.
With regard to macroevolution and evidence for it, there is such evidence.
Ring species are called such because they are species that can interbreed in one area but not in another. Example: salamanders or gulls.
There are gulls that exist in north America and Europe. These gulls are black billed in NA and white in Europe and cannot interbreed together. But go half way around the world and they can interbreed with each other and carry characteristics of each other. In other words, one species spread itself around the world, gradually changing. As members of the species either stayed or continued around the globe, they all had families in the place they stopped, occasionally moving as their ancestors did There is not enough traffic however to cause them to prevent speciiation (like humans who can interbreed with any other human). That is evidence of macroevolution.
