Darwinism is a Victorian age theory, facing 21st C science and understanding of information systems Darwin could never imagine.
That is the march of scientific progress.
You seem to think that the theory is threatened or in crisis because of these more modern discoveries. Modern genetics has given Darwin's theory additional empirical support.
The theory is doing very well. In fact, so well, that the only thing that could replace it given the evidence we have is a deceptive intelligent designer hypothesis, one that went to great pains to seed the geological strata with fossils arranged in way suggesting evolution and constructed with radioisotope ratios misleadingly suggesting deeper fossils are older, and to insert assorted taxonomical, anatomical, physiological, biochemical, embryological, and genetic nested hierarchies into the tree of life.
What most creationists fail to realize is that even if you could falsify Darwin's theory with a precambrian rabbit, for example, the existing evidence wouldn't disappear. It would need to be reinterpreted in the light of the new finding, which still wouldn't support the Christian belief in a god that wants to be known, loved, believed, and worshiped, and to be viewed as man's divine creator.
Such a god would not have designed our planet this way.
Furthermore, it still wouldn't allow us to conclude that a god exists. High tech extraterrestrials could fill that role.
it's not impossible of course, neither is a single cell morphing into a human by accidental mutations- but which is less improbable is our question.
Probability arguments work against god hypotheses. If one looks at some aspect of observable reality and says that it is unlikely to exist undesigned and uncreated, and therefore requires a god to account for it, he has made a special pleading argument. He is positing something orders of magnitude less likely to exist undesigned and uncreated than a cell or the genetic code, and assuming that the existence of such a thing needs no analogous creator.
I understand that the creationist doesn't normally have a problem making that claim, but the rationalist does. If probability is your guide, it argues most strongly against the existence of what would have to be the least likely thing imaginable to exist without help - an omniscient, omnipotent god
Once again not to say that your naturalist theory cannot also create one... but we'd need some evidence for that assertion, extraordinary claims.. as they say
The claim is (or ought to be) that life may have arisen and evolved naturalistically. That remains a possibility until somebody can demonstrate that it it is impossible. And as long as that remains a possibility, it should be explored, which is what many life scientists are doing. Abiogenesis research is making progress every year.
Likewise, the intelligent design hypothesis remains possible until it can be shown to be impossible. Mainstream science has determined that that avenue of research is sterile and chooses not to commit scarce resources to it, but islands of scientists who are also creationists are investigating that possibility. If they find supporting evidence, then we will have to take it into consideration. We're still waiting for the first observation the explanation for which requires an intelligent designer older than the intelligent life on earth capable of designing and creating.
