That didn't happen. Darwin observed many things, but finch beaks changing from year to year wasn't one of them. (That was the Grants, if it matters.) Darwin's finches are native to the Galapagos, and he only spent a month there. The importance of the finches was their similarity to one another and to birds on the mainland, i.e. it was the biogeography that was the interesting feature, not observed change. Darwin later inferred that nearby species tend to resemble one another because they are closely related and have descended from a common ancestor (the same conclusion reached by Wallace from independent observations).
In the terms we're using here, common ancestry is the cause of the similarities between the species, and evolution is the cause of their differences.
Well, of course the name for the phenomenon doesn't say anything about the cause of the phenomenon. "Erosion" and "combustion" are phenomena (and processes) just like evolution, and when we say that the shape of the Appalachians was created by erosion of higher mountains, we don't say what caused the erosion. So what? Erosion is still a cause, and so is evolution.
Which writers are you talking about? You seem to be trying to hold my feet to the fire here, and I find your argument completely unpersuasive. Like any physical process, evolution has causes and produces effects. Nothing you've written challenges that view in the least.
You seem to have a decidedly strange notion that phenomena cannot be both causes and effects.
Yes, that's natural selection. That process in turn causes other phenomena, like a rapid increase in the population frequency of certain alleles.
It also doesn't tell us anything about the meaning of the word "epideictic" or the origin of the infield fly rule in baseball. The list of things that natural selection doesn't tell us about is very long indeed. In what way is this supposed to be an argument against natural selection being viewed as a cause?
I'll ask again: how many evolutionary biologists have you actually talked about these issues with?
Also, what is your prediction for the number of genes in the ancient wolf genome?
So, change occurs over time—everyone agrees with that. However, assigning one cause for all change is fallacious and it leads to incorrect beliefs.
Let’s use an analogy: automobiles have changed over time. This has been called “the evolution of the automobile”. Yet, to suggest that “evolution” is the cause of this is ludicrous. Observations of change are only observations—they have no power to change or create anything.
In actuality, two very different kinds or categories of changes have occurred in automobiles over time. Go to any junk yard and you can see the kinds of changes which occur to individual automobiles. One of the causes for this category of change is ultraviolet radiation, for example. That’s a “natural” thing. Shall we then assume that all changes to automobiles have been caused by “natural” processes? No. That would be ridiculous. Human intelligence is the cause of the origins of each new model of automobile over time.
It would be helpful to see that one category of “change-over-time” (aka
evolution) can be called “uphill” as opposed to the other category which can be called “downhill”. Each category has different causes.
Most evolutionists and also creationists agree that if you selectively breed wolves you can eventually get a poodle. But you cannot do the reverse. Why not? The answer resides in the genomes. It is well-known that all dogs have less “genetic diversity” than wolves. What does this mean? It means that the genome of the wolf contains more diversity of alleles (aka gene forms) and perhaps even higher numbers of genes as well as higher orders of complexity in epigenetic DNA regions. So, the change from wolf to dog has been a “downhill” slide, genetically speaking. Such a slide should never be conflated with the presumed “uphill” genetic changes which would be required to produce the gray wolf genome in the first place.
Darwin’s proposed “tree of life” would necessarily require many many uphill genetic events, i.e. from prokaryote to eukaryote. How did that happen? It is ludicrous to offer “evolution” as an answer to that. It would be ridiculous to appeal to the downhill changes in many groups of life-forms, such as the wolf-dog continuum.
The term “
genetic erosion” describes the “downhill” processes which have undoubtedly occurred over time in many different “kinds” or continuums of life. Yet, where did all of these “kinds” originate from? Appealing to gene/allele-destroying processes such as selection and bottlenecking etc. in order to explain a requisite gene-building (and epigenetic-building) process is fallacious.
Hence, I reiterate that “evolution” represents only an
observation of change over time, having nothing to say about causation. And “evolution” (downhill) should always be clearly distinguished from the notion of “evolutionary origins” (uphill). The mechanisms for wolf > poodle “evolution” should not be confused with or conflated to be the same mechanisms that would have been required to produced the wolf from a population of ancestors which were genetically less-diverse than the wolf.
