[QUOTE="Eagle Eye, post: 2707016, member: 34489"] depends on what species concept you accept. There are a few species concepts, here are two examples, biological species and phylogenetic species. Evolution does not happen to individuals, but populations. If we have a barn full of donkeys and horses (two species living in one area), and after one mating season, there are now donkeys, horses, and mules, we would conclude that micro evolution had occurred, and some people would say macro evolution occurred. however, some would not say its macro evolution! Since donkeys and horses can breed and produce offspring, therefore horses and donkeys are not different species. Now, most mules are sterile, which would strengthen the argument that horses and donkeys ARE different species. BUT, some mules are not sterile (according to the interwebs). Thus, the answer in regard to macroevolution.... depends on how you define species. [/QUOTE]
