Microevolution is merely evolution, the change in allele frequency over time in a population of organisms, and all animals do this all the time.
Natural selection is always summing up the variation among a population of organisms and selecting those that show survivability and reproductive advantages, even is the selection does no more that stabilize the organisms phenotypes.
Look to the evolutionary history of horses or whales to see clear examples of evolution and selection through time.
none, it's called adaption; Dogs turn to Dogs,and Birds change to Birds. You can't get new gene's to change a bunny into a dinosaur. Evolution isn't possible. Unless A dog and a cat mate.
All animals are subject to natural selection.
According to modern evolution theory, all extant species exist now due to the rules of natural selection.
All species can, and did, evolve primarily through natural selection.

No, all life evolves. Bacteria evolve, viruses evolve, protists evolve, plants evolve, fungi evolve and animals evolve. Evolution is driven by Natural Selection. So, no. The evolution of all life on Earth is driven by Natural Selection: all bacteria, plants, animals, mammals, fish, insects, biochemical pathways, behaviours et cetera evolve by Natural Selection.
Yes, And also about the different species and how they evolve to adapt to their environment. (:
Natural selection is the primary way for organisms to evolve.æ However, it is not the only variable involved in evolution. Artificial selection,æwhereby specific traits are chosen to evolve by humans, is now commonplace and because we can genetically engineer organisms we will continue to do so.

Natural Selection
They evolve and adapt so they have traits hat are useful to them, by Natural selection. This means that members of a species that are isolated, well, natural selection makes those with the best chances for survival mate with each other and produce offspring with that trait.

Evolution is a gradual process that occurs through natural selection. Natural mutation results in some offspring.
They can, and we believe that they do. That's how all the animals (including the human animal) got to be the way they are.
