Snide remarks lacking substance are unwelcome. You very clearly implied that evolution was random in the post which I complained about. Prevaricating now does not alter the evidence.I am unaware of any evolutionary scientists who believes evolution to be a random process. It is a process wherein random variations are selected.
Interesting, since I never said or implied that evolution (as a whole) is a random process (nice twist though), but also think about what you have said here...So again, how did the referenced instructions within the code arise? Selection among RANDOM variations? Okay then how did these RANDOM variations arise, and do we KNOW of any alternatives that actually existed that were not selected? Or must we assume they must have existed?
Consider genetic drift as one characteristic mechanism of evolution. Understanding Evolution says "Genetic drift affects the genetic makeup of the population but, unlike natural selection, through an entirely random process." How about mutations? Random or not random? Most are clearly random so natural selection then genetically works on that which is originally random.
Then you could read Evolutionary Biologist, John Tyler Bonner's book, Randomness in Evolution. Obviously natural selection makes sense (that the best suited or healthiest would pass on their genes as opposed to the least suited and unhealthy) but it must select from among these random variations produced by the appearance and effect of random mutations that had arisen.
Epigenetic factors do not offer any long-term, significant mechanism for the inheritance of acquired characteristics.
I did not mention “acquired characteristics” (nice twist #2 though), just heritable changes in functions within the genome that effect phenotypical characteristics (these do not necessarily make changes in the DNA itself, mostly just how it functions in different organisms of the same species). They are however evidence of environmental influence which may affect transmission of certain propensities and talents. This is a really new but intriguing subject (I am keeping watch).
Those who could not swim would have died in their own generation, as would their offspring (if they even could have survived to reproduce), and we have no examples that such fish (or fishy creatures) even existed let alone became swimming fish.
But if you are saying swimming fish also existed with these non-swimming fishy types, and thus were selected, we have two issues to consider. One is that this would mean they already had the “referenced instructions” in their genetic code (which was my point and again where did these come from, how did they arise), or that there were others without these instructions or with alternate instructions, but to know this, we would have to have examples (unless we are to assume it), and there are none (I have looked for them).
As a matter of principle I will disccus issues only with people whose posts are honest and well intentioned. Your persistent equivocation loses you that privilege.
