IBefore the industrial revolution there were only peppered moths. Black moths couldn't live long enough to reproduce because they stood out on the peppered tree trunk. Once the pollution started turning the tree trunks black, black moths appeared and peppered moths were gone. This is an example of chance mutation in the color pigment of this moth and this new mutation being favored.
So basically we got something different that wasn't there before. Nature didn't select the black moths over the peppered moths, it selected for the chance mutation in the species that created a more fit individual.
So you don't think evolution is a fact because we haven't observed an animal acquire feathers in the few thousand years we keep written records. Fine. I'm in the scientific community and evolution is an open and shut case that is accepted throughout.
We know there weren't always birds, humans, insects on this planet. We know there used to be only less complex organisms a long time ago. So where did all these new organisms come from at different times?
louiedog, I think there are theories that the universe has just always been there. That's what I think.
