lvbuckeye;903596; said:talk about the Lord working in mysterious ways! i just stumbled upon a verse that seems strangely appropriate to the conversation:
II Timothy 4:3-4 For the time will come when they will not endure sound doctrine; but after their own lusts shall they heap to themselves teachers, having itching ears;
And they shall turn away [their] ears from the truth, and shall be turned unto fables.
Moths.lvbuckeye;903619; said:reality around them? really?
perhaps you could point out an example of evolution occurring around us right now? don't give me that 'it happens too slow to observe it' crap, either. you said it's reality around us, so back it up. i want a hard example of direct observation.
BTW, why are there "endangered species?" if they're so unfit as to be endangered, then shouldn't they start evolving into new, more fit creatures? alas, that doesn't happen. what's gone is gone, never to be replaced.
give me a break.

lvbuckeye;903660; said:they're still viruses and bacteria. they haven't become anything else. give me an example of a mutated bacteria that wasn't a bacteria anymore, but was something else.
Wish you hadn't used the language "deceitful" that interjects a value judgement into what should be an intellectual debate.lvbuckeye;903659; said:two problems with that example.
1) the moths did not live on the tree trunks, but rather the underside of the leaves. in light of that, the integrity of the example is called into question due to the fact that it has been presented in a deceitful manner.
So, not resting underside leaves, resting on wood of one type or another. Camouflage mechanism for predatory selection still applies.From their original data, Howlett and Majerus (1987) concluded that peppered moths generally rest in unexposed positions, using three main types of site. Firstly, a few inches below a branch-trunk joint on a tree trunk where the moth is in shadow; secondly, on the underside of branches and thirdly on foliate twigs. The above data would appear to support this.
Natural selection at work though lv, and that, along with new genetic coding OR expression are two of the most obvious engines for evolutionary development.lvbuckeye;903659; said:2) the condition for lighter or darker coloring was already present in the gene pool. the shift from more lightly colored moths to more darkly colored ones is most certainly an example of selective breeding, or more likely a culling of the lightly colored members from the gene pool through predation, but it is not an example of new traits arising; something which MUST occur for evolution to progress.
Well, the population has indeed evolved. At worst you might claim it to be micro-evolution, but you likely know that the response to that is that such a qualification means one is debating merely the time and scale of response.lvbuckeye;903659; said:oh yeah, since no one seems to recognize the fact, it must be pointed out that they are still moths. they haven't evolved into anything... i want to see an example of the peppered moth becoming something other than a peppered moth.
Now we come back to what is really a classic side-stepping of the issue.lvbuckeye;903659; said:it's reality according to BKB, so there must be at least one instance where it's been observed, right? surely there's been observation of a creature becoming something else...
how about those fruit flies? they've been mutating them for 50 years. have any of those countless generations ever become something other than a mutated fruit fly? surely they've evolved into something else by now...
Micro and Macro evolution are very distinct as (sigh!) we do not see macro-evolution occuring, this concept is based on pure inference.Okay, let's accept this blatant falsehood for the sake of argument. Tell me what is stopping "micro" evolution, which you acknowledge to occur, from becoming "macro" evolution with sufficient time. Inferences aren't automatically wrong because you say so, especially when they make sense. Explain why "macro" evolution still doesn't work when given millions of years. And don't feign impatience with me, you pedantic mouth-breather. I'm the one that has to lead you through basic concepts by your malformed flipper-hand.
you are still missing the point that a new species of fruit fly is STILL A FRUIT FLY. i'm not talking about speciation. i am well aware of how that works, and have made no effort to deny it. my argument is against citing examples of microevolution as scientific support for macroevolution. macroevolution only occurs in theory. it has never been observed.sandgk;903729; said:Wish you hadn't used the language "deceitful" that interjects a value judgement into what should be an intellectual debate.
Let me address the substantive claim you make - that peppered moths rest on the underside of leaves.
It is true that the female will lay her eggs on the underside of leaves. It is not true that the dominant locale of daytime rest for the adults is demonstrated to be on the underside of leaves.

Natural selection at work though lv, and that, along with new genetic coding OR expression are two of the most obvious engines for evolutionary development.
The presence in a gene pool of both characteristics does not mean that this example is invalid viz-a-viz evolution. It provides a simple example of one of those engines in action.
(The precise cause of which you likely realize has been the subject of debate. But, the impact of environmental change and resulting predatory pressures still appears to be the most plausible explanation. Wells' objections - which have essentially been refuted - notwithstanding).
Well, the population has indeed evolved. At worst you might claim it to be micro-evolution, but you likely know that the response to that is that such a qualification means one is debating merely the time and scale of response.
Now we come back to what is really a classic side-stepping of the issue.
You set up a predicate - show me a new organism that has arisen before our eyes. A man with three buttocks if you will. On it's face this casually ignores the likelihood, supported by very substantial fossil and scientific evidence, that such successful development of an entirely new competitive species can take much time to occur.
You support that predicate by stating that with all the work done to breed fruit-flies we surely must have created a new species from the same. Which is odd, as speciation has been demonstrated repeatedly with D. melanogaster.
Do you thus seek to preemptively dismiss the work of Rice and Salt, or that of Diane Dodd [ibid], or did you simply not know of the same? Speciation arose respectively within 35 and 8 generations.
