I don't accept evolution for a few reasons, but a big one is that it doesn't make sense from a continual, ongoing process. If, as evolutionists claim, fruit flies always come from fruit flies, then what was the predecessor to the first fruit fly? They weren't around forever.
(This is the point where select evolutionists will tell me I don't know what I'm talking about, impugn my education, and otherwise ignore the question.)
We name organisms, they don't name themselves. Yes a fruit fly will produce a fruit fly, but the new fruit fly is not a genetic copy of its parents (just as you aren't a genetic copy of your parents) there is a combination of dna from both parents and mutation, thus a new instantiation of the thing in question. If we take two populations of identical fruit flies and separate them and give them very different environments--different food, different pressures, etc--we will get after many generations different populations of fruit flies. It may even result in one of those populations over enough time becoming a new species (that is, generally unable to produce viable offspring with the parent or sister population(s)). We can still call them all "fruit flies" and they never did anything but "reproduce after their own kind", but their "kind" through natural selection has changed over time.
Polar bears are, in some sense, just brown bears who adapted to the arctic environment. They are a distinct species to the brown bear now, but both polar bears and brown bears evolved from a common ancestor. And yes, both are "bears" so you could describe this merely as "micro-evolution" the problem is that there is nothing in nature to stop "micro-evolution" from being "macro-evolution". If we were to get into a time machine and go back far enough we'd find the ancestor to both canines and bears, and it is precisely the same sort of divergence that produced the difference between polar bears and brown bears--there is no different mechanisms in place, just time and genetic mutation, natural selection. The exact same mechanisms at work, though at an artificial level rather than natural level, which have produced the many different dog breeds which all descend from the common wolf. We can say that, yes, they are all still dogs, or all still canines, but then we bring in the bears and we still can talk about that dogs and bears are still both
caniforms. And that's how it works.
Kind after its own kind results, with natural selection, in the vast diversity of life on earth. So, yes, all known living things on this planet are ultimately descended from the earliest forms of life which evolved on this planet--how the earliest life arose is still a mystery to science, and it is important to understand that evolution is not abiogenesis; abiogenesis is a proposed idea that life arose from non-life but the theory of evolution very specifically deals with
living things not with how living things came to be in the first place.
