I don't know about "inevitability" and all that. But I will repeat something I've said a while ago, and expect to repeat a few more times before I die (if the Lord tarries... hmmm, is that one of the doctrines we will have "outgrown in 500yrs?). Here it is:
The last people who will be defending Darwinism and every other form of evolutionary theory will be Christian theologians, long after the scientific community--whether dominated then by religious or atheist types--has shelved the whole notion as an antiquated and backward paradigm for interpreting reality, and replaced it with WHATEVER.
They will defend it, along with the rest of the "scientific dinosaurs" who haven't yet retired from their prestigious professorial chairs at leading universities. I think we're already seeing the beginnings of a kind of wagon-circling behavior, led by RDawkins and others, backed mainly by philosophers and media (i.e. Hollywood) promotion.
I-D proponents, even with the glaring flaws in their stance, are busy making a fatal case against the future of gradualism or punctuated-equilibrium as evolutionary modeling. Darwinism is done for, and its religious-like zealots will not be missed, even by those who "honor their memory" and ascend in their places in academia.
And a certain kind of Christian man-pleaser will still be writing books and articles accommodating his exegesis to the previous generation's "assured scientific results," become passe while he wasn't looking. Others will be standing on the trending street corners, striking the most provocative poses, pathetically trying to "hook up" their theology with the latest spirit-of-the-age. Because they want more than anything else to be
influential and
respected by the WORLD.
More's the pity...
