The original article has nothing to do with this. how do we know? because the scientist only studied a single generation. new traits and genetic change comes from consecutive generations.
That’s not true Evo, there was at least one new generation born during the experiment and possibly two. I’m waiting for a ICR scientists to get back to me in relation to this experiment. So there was a consecutive generation. Changes must be observable sometime Evo.
Are you suggesting that nothing happened to show any evolutionary change in the new born lizards?
Because if you are, then you are actually legitimizing the ICR observations.
I can assure you there wasn't two successive generations. That would mean that the newborns would have to have hit sexual maturity, breed and produce offspring all within the same first day they arrived. their may have been one addition generation but because the biologists weren't focusing on that aspect of evolution, it really has no relevance ever.
On to the actual issue though. The biologists working in this study had no intentions of gathering information on the changes in successive generations. That is why no information (in the original article) make any conclusions on that matter. I, nor the biologists in the original study, have any comment what so ever on the changes in the next generation.
That is not what they were attempting to observe.
Bronzesnake said:
Evolution would have us believe that environmental conditions are the driving force behind the theory.
So this experiment was set up to observe and to look for any changes.
No real physical changes were discovered except for perhaps size and strength, which no one is arguing against. This is exactly what we expect it’s called micro evolution.
All except that last sentence made perfect sense!
It isn't micro evolution because that would infer that the conclusions the biologists have accumulated were that of changes in the next generation, which they weren't, the changes we see in size and strength are that of the original population. This is not a case of Micro evolution. This is, however, a case of environmental factors having an impact of a population. Evolution only occurs when successive generations are born. You know this, I know you know this. However, all the information that was gathered, was that of the original population, not of the successive generation. If the original study was meant to focus on that then they would have added another month or so so that the eggs were able to hatch. But in the case of 4 months, we would have very few, if any, hatch.
Bronzesnake said:
My question to you is how long do we have to wait, how many generations from these original lizards do we have to wait for before we begin to see any changes? Three? Five? Seven? Eleven? Six Hundred thousand? If these environmental conditions are actually responsible for evolutionary change, then why didn’t it work during this experiment?
It only takes one additional generation to have new changes genetically. Physical changes, however, all depend on the genetic change. The environmental conditions are influential to evolutionary change, but not 100% responsible. They didn't work in this experiment because this experiment wasn't supposed to be judging evolutionary change.
Bronzesnake said:
The offspring were virtually identical to their parent which is exactly what we always observe in nature Evo. ICR is simply reinforcing this fact by pointing out that there was no discernable evolutionary addition to the genetic information. In fact, the lizard population actually decreased during some of the experiments and that is not good for Darwinian evolution!
Would you please be able to show me this information in the original article please? A decrease in population has nothing to do with evolution, it only has to do with natural selection. If a population decreases, that would actually confirm natural selection. If an organism is out of place in it's environment, then it most likely will die off. However, the experiment doesn't say that the population decreases in all 3 circumstances, only the two. So it is rather misleading to say, in a general sense, that the population decreased. Because, in all 3 circumstances, the population only decreased in two. This, however, is irrelevant anyways because of the mention of genetic changes, which wasn't documented in the first place because that was not the intent of the study.
Bronzesnake said:
Why haven’t these lizards developed a poisonous film over their bodies for example, which would force their predators select other meals?
Because there was no evidence of a second generation in the original article. That, and such a drastic mutation wouldn't suddenly occur in a single generation, but rather many generations gradually.

Now I can predict your reply, you’ll say that this experiment was too short for any of these conclusions to be reached, however Gould and Eldridge for instance, have abandoned Darwinian evolution because it cannot, and has not been observed in the fossils.
Bronze, there will be, in every single theory, law, and hypothesis of science, another scientist will disagree with it in some sense and to some degree. Gould even wrote a book about Evolution as a fact and a theory. Not only that but, in Gould's words, he states:
Transitional forms are generally lacking at the species level, but they are abundant between larger groups.
I've already addressed this in another topic (I believe it was of your same statement as well, although it may have been someone else). Regardless, this has nothing to do with the original article and it's studies.
Alas, to further explain that point, Gould says:
Since we proposed punctuated equilibria to explain trends, it is infuriating to be quoted again and again by creationists—whether through design or stupidity, I do not know—as admitting that the fossil record includes no transitional forms.
Bronzesnake said:
So, they came up with an alternative explanation and they stated that changes did happen abruptly, and very quickly, and so in light of this concept, it is perfectly credible for scientists to come to these conclusions using a short term experiment such as this one where offspring were born and observed Evo.
It would have been acceptable for the ICR to make such claims if the original article had data in which the ICR is referring to. The fact is, the original article has no data and never once says that "successive generations had no change at all".
Bronzesnake said:
As you know we have studied long term life forms in many varied environmental conditions and we have not observed any macro changes (other than those inferred examples which are illustrated), and so now we are responding to P.E. and are discovering that there are no macro changes involved here either.
Very legitimate conclusions Evo.
The only apparent issue you truly have is that, again, you just can’t come to understand there are alternate explanations other than your own.
If there
was a macro evolutionary change in just one successive generation, that alone would completely falsify evolution. However, the original study has no information on whether or not the second generation had any change or didn't. There for, it is irresponsible for anyone to claim that they did.
Bronzesnake said:
reproduction with variation. The study the biologists did was about the variation between a single generation with different environmental factors. the only variation they are talking about is between size and strength due to the more food they acquire and the longer they live without having to consistently hide. These aren't new traits!
I agree, no new traits, as is exclusive in every instance.
There were no new traits because the biologists weren't looking for new traits in the next generation. Why is this difficult to comprehend exactly? Not only that, but there is not evidence in the original article that shows another generation even was there! For there to be new traits there has to be a second generation. Even if there was one the biologists weren't going to pay attention to if they had new traits or not because that's not what their study is about.
Bronzesnake said:
What the ICR, and you, don't seem to understand is that the scientists are not focusing on Natural selection as a whole, but an individual section of Natural selection on those islands only.
What you don’t see understand is this experiment was used to hypothesis of evolutionary biology in general!
The actual scientists who did the experiment say this experiment is “
central to evolution†so perhaps you need to withdraw that idea Evo.
Yes, because natural selection is part of evolution! of course it's going to be central to evolution then. but the study isn't about mutations through generations, it is about which environmental factor has more of an effect on a certain population. By effect I dont mean additive trait or a subtraction of one, I only mean of the specimens in that population.

Here’s a quote from the actual scientists who ran the experiment...
It is not clear that this result says anything about natural selection in species other than anoles, Calsbeek explains. But for him, that isn't the point — his work pushes forward the project of experimentally testing the hypotheses of evolutionary biology, a field that isn't well known for working with real organisms. "This represents one of the first large-scale experimental manipulations of a process that is central to evolution," he says. "This really is a hard experimental science. You can manipulate agents of selection and test hypotheses about how the process works."
Yes, and I realize, except the experiment has nothing to do with successive generations or what mutations or traits occurred or didn't through those generations! It only has to do with the changes in the population. that is it.
Bronzesnake said:
That pretty much puts the kybosh on your assertions that the scientists are not focusing on Natural selection as a whole
no, actually it doesn't. that same quote shows that their intention was to see how natural selection plays a part.
It is not clear that this result says anything about natural selection in species other than anoles.
It is not natural selection as a whole, but only directed towards the anoles.
Bronzesnake said:
ICR wrote: Natural selection by predation did not produce new anole lizard traits, let alone a new organ or whole creature.
Of course it didn't, because there was no succeeding generation!!!! That was not the intent of the study! does this honestly not make any sense to you and the ICR?
They did produce at least one new generation and possibly two by your own admission, so why do you keep making these incorrect statements?
I said their may possible be at least one new generation, but the original article never speaks of this at all. Not only that, but the gestation periods and incubation periods are both conservative numbers, for the sake of argument. meaning that even if there were hatchlings, very few would have actually hatched and even if the biologists were trying to study new traits, which they weren't, they wouldn't have used only a small percentage of the entire populations hatchlings, they would have used all of them to get accurate data. But we dont find this data because the study isn't based on finding new traits or mutations!
The sole purpose for this study is to see which effects the
current population of the Anoles. snakes, birds, or competition.
