I noticed you are not answering my questions.
I noticed that your questions were of the form of "more instances" of variation within a species -- I simply point to longstanding examples of "variation within a species" to point out that "more of the same" is not helping your argument AND to show that the concept of "variation within a species" even to the point of "manipulating and BREEDING for those variations" was being done long before Darwin.
Another "inconvenient detail" you choose to ignore.
And the crux of the matter is what is the mechanism that brings about that variation within species and what are the long-term implications of continued variation. Claiming that variation occurred before Darwin ventured an explanation of the mechanism for that variation and its consequences in the theory of evolution is meant to show what exactly? That you don't understand the concept of descent with modification by natural selection?
[quote:2g2xvl83]I ask again, if some earlier understanding of descent with modification through natural selection was realized
descent with modification in the form of dog breeding had been done for centuries "obviously".[/quote:2g2xvl83]
Why have you quoted only part of my paragraph - and indeed even ignored the rest of this opening sentence? To avoid the question I asked you? I ask again that, if you believe that dogs bred through artificial selection in some way demonstrate that the concept of descent with modification by natural selection was understood and expressed before Darwin, who so understood it and expressed it?
You keep wanting to ignore that point. But remember it was YOU who first claimed that ANY variation within a species is "neodarwinism" AS IF Darwin discovered dog breeding and all other examples of variation within a species.
I do not recall ever mentioning neodarwinism. You again make stuff up about what I have said. In the church I was brought up in, this constitutes a lie and is a sin. Variation within species is indicative of a mechanism at work causing that variation. Ring species - which you have still not addressed - are evidence of this mechanism in operation, as are several of the other examples I gave you. Darwin identfied such a mechanism and gave expression to its long-term consequences in the theory of evolution. If you have a different theoy with supporting references for what causes descent with modification, I for one am anxious to hear what it is. I am interested that you have previously admitted to accepting microevolution, yet have no explanation for the mechanism that brings it about and have not yet elaborated what constitutes the watershed that blocks the transitioin from micro- to macroevolution.
I never made such a sweeping claim about Darwinism -- you did!
You make stuff up again. I made no claim that 'Darwin discovered dog breeding and all other examples of variation within a species.' Your argument is unfounded, fallacious, trivial and appears directed towards libelling Darwin's contribution to knowledge and understanding
[quote:2g2xvl83] Your repeated example of dogbreeding is trivial and naive in any discussion concerning microevolution and the interface between it and macroevolution,
I admit that it is "an inconvenient details" for your argument -- that you choose to ignore due to the glaringly obvious point that it makes.[/quote:2g2xvl83]
Perhaps if you expressed the 'glaringly obvious point' more cogently and carefully, it would be more easy to recognize and understand what you mean. it seems to me that the only 'inconvenient details' are the ones you wish to gloss over that tend to support the theory of evolution.
Not sure why you think the objective unbiased reader - or I - would want to join you in ignoring this prime example of variation within a species - in fact descent with modification seen at it's best!!
Observing something - in this case something artificial - in action is not the same as understanding and describing the mechanism that brings it about in nature and its consequences for the evolution of species.
[quote:2g2xvl83]Your point about the simple number of chromosomes amongst chimps/tobacco and humans/hares is a red herring,
As are the same kinds of speculative arguments darwinists made on that point. I simply point to the existence of the number of chromosomes. HINT even your own darwinist friends tried genetic linking of the banana to the dog in that video we all watched![/quote:2g2xvl83]
If you are responding to a point I am making, please consider responding to the whole of that point. Your arguments do not address that point in any sensible or intelligent manner. '[P]oint[ing] to the existence of the number of chromosomes' is supposed to establish what exactly? That different species have different numbers of chromosomes?
[quote:2g2xvl83]the ABO polymorphism in both species is highly suggestive of shared ancestry.
How so?
Your use of "highly suggestive" appears to be a paraphrase of "stories easy enough to make up" I suppose you already noticed that.[/quote:2g2xvl83]
ABO polymorphism exists in species that are closely related in taxonomic groups organized in a nested hiearchy that owes nothing to blood-group analysis. Equally, molecular genetic analysis suggests that closely related taxonomic groups are equally closely related through their DNA, each metric for determining this relationship being independent of the other. Thus we have three lines of evidence that suggest relationships amongst groups - and species within those groups. That DNA testing can be used reliably to determine relationships between individuals and amongst groups within a species is also indicative of the fact that, when similar relationships can be determined amongst different species (another point you have not yet addressed), that determination is also reliable.
[quote:2g2xvl83]how much you dislike the work of Darwin and his successors that points unequivocally twards this shared ancestry.
"unequivocally points toward shared ancestory" is simply "making stuff up" unless you can show with actually SCIENCE that species B comes from species A -- in real life.[/quote:2g2xvl83]
No. See the arguments above.
[quote:2g2xvl83]Why do you not think it in any way significant that the gene that controls the development of a mammalian eye in a mouse will bring about the development of an insect eye in a fly? What do you think would be a reasonable conclusion to draw from such an observation?
That you are a bush-native dealing with two very different computers and when you slap a MUX board from one on to the other you notice that it "works". (A "hint" to everyone else that the designers were using standardized interfaces to some extent)[/quote:2g2xvl83]
Argument by analogy is not evidential and yet even this analogy is faulty. Your analogy seems to be implying that God created flies out of one box of bits and then mice out of pretty much the same box of bits but with a few different pieces thrown in for good measure (or vice versa, I'm not sure which). Are you implying that God made humanity, chimps, gorillas and the other primates out of the same box of bits, with a tweak here and a tweak there? Sounds a bit like evolution to me.
You also seem to be suggesting that putting a component into a computer that works is in some way the same as causing that component to grow within (or on) the computer as a result of placing a tiny piece of the component on the computer, even if that tiny piece is from an entirely different computer.
Such efforts at "toying" with the technology that someone else created and which you have no clue how to make yourself -- does not prove that machine A evolved from Machine B.
Assuming your conclusion, I'm afraid. You must also be aware that science is rarely a quest for proof (which admits of no doubt), but rather for evidence with which to support or falsify a particular hypothesis. You will have long since noted that evolution is widely understood by the scientific community to be so evidentially well-supported that it is considered to enjoy the status of a scientific theory.
Again - I am just stating the glaringly obvious here.
So am I.
[quote:2g2xvl83]Do you consider that the evolution of, for example, the AIDS virus has anything to contribute to our understanding of microevolution and/or macroevolution?
No more than breeding dogs. Why do you run away so devotedly from that easy example?[/quote:2g2xvl83]
I am glad that you realize that the artificial selection of desirable traits by dog-breeders is compelling evidence for the mechanism of descent with modification by natural selection. As far as HIV is concerned, you must surely be aware that the rapid evolution of viruses such as HIV is compelling evidence for descent with modification by natural selection from a common ancestor? Dogs are bred by artificial selection; HIV is not.
Recall that you are the one that wanted to equivocate beween variation within a species (breeding dogs) vs darwinian macro-evolution (reptiles producing birds).
I recall asking you where you think the watershed between microevolution and macroevolution lies. I do not recall you answering this question.
[quote:2g2xvl83]Does the selective host viability of lice tell us anything about microevolution and/or macroevolution?
No more than breeding dogs. Why do you run from that example of variation?[/quote:2g2xvl83]
See my comments above.
[quote:2g2xvl83]Do you think that the ability reliably to determine relationships amongst individual humans and populations by molecular genetics has any meaning for the ability to determine relationships between species?
Because as we both saw in the video below - the same argument goes all the way back to trying to argue that "bananas are related to dogs" - in that entertaining rabbit trail of "stories easy enough to make up".[/quote:2g2xvl83]
I see you did endeavour to answer this question after all; my apologies. Sadly you wholly miss (or deliberately avoid?) the point of the question. See my previous comments in this respect.
