I don't like the word 'proven' applied to science, but evolution is as strongly supported by the evidence as any major scientific theory, and IMO the only serious deficiency in it lies at the very beginning of life, since we're only beginning to discover how the simplest one celled organisms evolved. It would be nice, also, to have more pre-Cambrian fossils, but that gap is covered quite well by molecular evidence.
Of course, there are always new things to learn. For example, we still need to learn the precise molecular mechanisms behind major morphological changes - development of feathers, limbs, etc., but that research are is progressing rapidly.
And I hope I'll live to see some extinct species recreated from DNA fossil relics, with perhaps some deductions from molecular phylogeny. Dinosaurs are too much to hope for, but we might be able to do a mammoth or even a saber-tooth. How cool would that be? :-)
Very!
Back in the mid '70s I was working on a survey of all the museums in the USA. One of the questions was something like "are you engaging in breeding programs to try to recreate extinct species?"
That's the truth. And, as long as scientists are willing to examine their assumptions in light of the evidence and reason, Christianity has nothing to fear.
