According to evolutionists are there many species that devolved rather than evolved?

I love a thinker. Lots of thought has gone into this one. It is my thought that the human race consisted of many branches. Neanderthal and Crow Magnum. The Pygmy and the Merci. American Indians and the Europeans and so on. Many have gone extinct due to war and/or inbreeding. I believe that every branch of the human race was "created after its own kind" but still human, whether physically deformed or normal. I could go on. Thanks for the thought.
