If we're not talking about Darwin's theory of evolution, then who's theory are we talking about?
We’re talking about a scientific theory to which many have contributed (and many more are still contributing), certainly and preeminently Darwin, but whose particular contribution was not the very ideas of evolution and natural selection, each of which had been around for a while, but the proposition that natural selection was evolution’s principal mechanism. Even so, Darwin did not come close to fully explaining the dynamics of natural selection, including speciation, and of course had little inkling of the molecular/genetic aspects, especially regarding the actual beginnings of life. (In private correspondence, he did speculate that life probably started in a “warm little pond”, but could offer nothing more ) In sum, if you want to try to use Darwin’s own words against him, you may be able to trip
him up, but not his theory. (Similarly, Newton was clearly wrong in some of his assertions concerning space and time and gravity, but by no stretch of the imagination is his work therefore “disregarded” today.)
Moreover, I sense a naivete here about science in general. In the same way critics enjoy arguing that evolution, to be true, must ultimately rely on the quite unlikely chance of certain structures, like genes or cells, suddenly springing into being whole and complete, you seem to be suggesting that a scientific theory, to be taken seriously, must likewise be whole and complete when first proposed, and in addition stay that way. But that’s not how science works; that’s not even what science is. In the normal course, for the vast majority of the time, science is not about the creation but the subsequent “working out” or “fleshing out” of theories. (To put it another way, science subsumes the theory of evolution but the process of evolution subsumes science.)
I was merely stating that there is clear evidence that what Darwin claimed would cause his theory to totally break down has been found in a number of ways.
And I was merely stating that you’re wrong. To be sure, the claims of “irreducible complexity” you point to must come to be addressed by the theory, but that work is on-going, and no one, especially evolution’s critics, are in any position to assert that “irreducible complexity” in those cases has been proven. As I noted before, there’s still so much to learn about biochemistry, and not just as it concerns evolution. (Also, regardless of the science, your contention amounts to proving a negative, which while practical for trivial or simple realities and concepts, is exceptionally difficult for complex ones.) Indeed, your contention is no different from someone’s being handed a Rubik’s cube for the first time, already twisted about, who then opines, without further examination, that it “certainly” could never be “reworked” into a simpler configuration where each side consists of only one color. Of course, it can, but for most people, some quality time (not to mention a load of frustration) is required to confirm (or disparage) the fact.
Consider the following explanation from evolutionist biologist Frank B. Salisbury from American Biology Teacher, Sept. 1971, pg. 338:
". . . think of the system that would have to come into being to produce a living cell! It's nice to talk about replicating DNA molecules arising in a soupy sea, but in modern cells this replication requires the presence of suitable enzymes. . . .How, in the absence of the final enzyme, could selection act upon DNA and all the mechanisms for replicating it? It's as though everything must happen at once: the entire system must come into being as one unit, or it is worthless. There may well be ways out of this dilemma, but I don't see them at the moment."
The last quoted statement clearly shows Salisbury doesn’t believe “irreducible complexity” has been proven; he’s merely raising the issue, which is all well and good.
But I am reminded of a well-known cartoon titled “The Origin of Life”. (I don’t know the cartoonist.) There are three frames, each showing the same natural landscape. The first highlights a small area and reads–“3,562,027 years ago: Two amino acids drift together.” The next notes–“6 seconds later: They drift apart.” And the last reads–“482,674,115 years later: Two amino acids drift together.”
It evinces the same pessimism Salisbury has, but is double-edged, for it belies a telling pessimism about chemistry as well. There’s a lot of work being done at present to discover the much simpler precursors to RNA, DNA, enzymes, proteins, etc. that evolution counters must have existed, but I guess the fact of that work will fail to impress skeptics as long as they continue to underestimate/underappreciate the power, range, and diversity of chemistry.
Here’s but one example that helps to undercut such pessimism. Query: Is there a discrete and “roaming” collection of molecules in the world that totally depend for their replication and “survival” on their chance encounters with other molecules? You bet there is. We call them viruses. And their “iffy” propagations have caused and continue to cause us human beings no end of distress. (Ditto for the quite different if no less “worrisome” prions.)
Whatever we think we know about chemistry, we still don’t know enough to fail to stand in awe. And we certainly don’t know enough to toss out (all too cute) improbabilities about the origin of life and then hail them as some kind of damning, incontrovertible proof against evolution.
I do think the idea that such complex systems instantly appeared out of primordial soup and just happened to be functional is extremely ignorant.
Evolution proposes no such thing. Part of what evolution does propose, in further answer to the concerns Salisbury raises about DNA, is that there is no reason to believe that replication and “purpose” (or “information") had to go hand-in-hand. Instead, evolution posits that before there were self-replicating molecules with “codes” (as in DNA), there had to be much shorter, simpler, self-replicating molecules with no “codes”; function and purpose (beyond replication) came later.
