Note I said **definition,** not explanation. I agree that very many explanations of selection as nonrandom exist.

Very famous and well-known passage you have produced. A close read reveals that Dawkins says, concerning living things "....too improbable....to have come into existence by chance." THEN he conveys "Darwin's answer." Note the fact that Dawkins is invoking Darwin the founder of natural selection. Darwin died in 1883 and Dawkins published his book in 1986. So where did anyone obtain the idea that Darwin had become irrelevant? Dawkins, of course, is writing as a Darwinist. That said, Dawkins then conveys Darwin's answer as "gradual, step-by-step transformations," followed by these statements "....to have come into existence by chance," and "to have arisen by chance." Both statements say it could have happened by chance; if you don't believe me then just read them in context. Then the very next thing Dawkins says, "But the whole sequence of cumulative steps constitutes anything but a chance process...."
Let's stop right there.
In summary: Dawkins tells us he is relating Darwin's answer as to how species (units of organized complexity) come to exist. He then says the object of explanation comes about via a gradual step-by-step process, which he then affirms TWICE is by chance. THEN he says, not quoting Darwin or speaking for him, the entire cumulative process "constitutes anything but a chance process." So here we have a very clear admission that Dawkins, not Darwin, is adding on the nonrandom claim. Hold on. Dawkins is saying: the FACT that each step is gradual AND slight the same gives him the right to describe the cumulative process, after the fact, as nonrandom or nonrandom survival.
Fact: The Dawkins quotation is an explanation of natural selection. He says, early on in his book, just that.
Fact: He is careful to convey "Darwin's answer" is step-wise chance. Two times he says each step is by chance.
Fact: He is careful to describe the cumulative theory as nonrandom----**which is conveyed as his descriptive conclusion.**
Fact: We have a clear admission, by implication, that Darwin did NOT convey a nonrandom selection process; rather, the same is a conclusion reached by Dawkins. If Darwin had said nonrandom or any synonym then Dawkins would have surely quoted Darwin or said Darwin said.

Note the fact that Dawkins accounts for the concept of sieve, but says the same could NOT have produced organized complexity----the degree found in living things.

"Sieving of this order of simplicity is not, on its own, enough to
account for the massive amounts of nonrandom order that we see in
living things. Nowhere near enough. Remember the analogy of the
combination lock. The kind of non-randomness that can be generated
by simple sieving is roughly equivalent to opening a combination lock
with only one dial: it is easy to open it by sheer luck. The kind of nonrandomness that we see in living systems, on the other hand, is
equivalent to a gigantic combination lock with an almost uncountable
number of dials. To generate a biological molecule like haemoglobin,
the red pigment in blood, by simple sieving would be equivalent to
taking all the amino-acid building blocks of haemoglobin, jumbling
them up at random, and hoping that the haemoglobin molecule would
reconstitute itself by sheer luck. The amount of luck that would be
required for this feat is unthinkable, and has been used as a telling
mind-boggier by Isaac Asimov and others....Simple sieving, on its own, is obviously nowhere near capable of generating the amount of order in a living thing. Sieving is an essential ingredient in the generation of living order, but it is very far from being the whole story" (Dawkins pgs 44, 45).
