Okay I have a question. In micro-evolution, traits change among the same species, enough of these changes leads to macro-evolution. What is macro-evolution other than a different name and a series of small changes? A change big enough so that the new organism is no longer of the same species, and cannot mate with the original species anymore. This makes me question something... Mutations would only affect one organism, correct? It would be too coincidental for a group of organisms to all evolve into the same new species. So how does the new species reproduce if it's not asexual? If it's the only one of it's kind? If it could reproduce with the parent species, then it would BE that species itself, so how does a new organism representing a new species reproduce?
