Imaginary time you say? What do you base that on? It's pretty common knowledge that the earth is 4.6 billions years old. So what is it that makes you reject the 2 billion years?
I find it incredibly funny that he'd mention "
imaginary time", seeing as it's one of the few concepts even more outlandish than dad-cosmology. Nope, those several billion years are
definitely not imaginary time
This isn't evidence for Darwinism.
If you didn't have a long history of demonstrating zero understanding of that term, you might have a point...

Just a few picks:

Apparently the researchers aren’t even sure about the genetic basis for the change, another suggestion that the “evolution” did not involve any new genetic information in the lizards.
Or it might suggest that they hadn't managed to investigate the genetics in sufficient depth yet. AiG seems unaware that scientific research takes time, expertise and resources.

McGill University biologist Andrew Hendry noted, “All of this might be evolution. The logical next step would be to confirm the genetic basis for these changes” (emphasis added). Hendry wonders, as Menton suggests, if the change was simply the lizards’ “plastic response to the environment.”
Hendry is completely justified in his caution. In fact, evidence since came to light that the changes in gut morphology are at least partially plastic. In
this study, the researchers compared wild-caught "herbivorous" (H) lizards to "herbivorous" lizards that were fed arthropod diets for months (HA), and HA lizards to wild-caught members of the insectivorous (I) parent population. The results?
- the prevalence of caecal valves is much higher in H than in HA (12/16 vs 0/20)
- gut proportions are different between H and HA - but also between HA and I
That is, lizards from the "herbivorous" population do lose some of their herbivorous features if they eat only arthropods for a while, but don't completely regress to the ancestral condition. Precisely how much of that is genetic is still up in the air, as far as I can tell. Also, note what the study did NOT investigate. They didn't take any lizards from the original population and try to feed them a vegetarian diet. So while the herbivorous "adaptations" undoubtedly have a lot to do with phenotypic plasticity, we don't really know if the plastic
response itself has
undergone a genetic change.
Another thing they didn't do is take lizard
eggs from each population, and raise the hatchlings on different diets. If the population differences are wholly epigenetic, then the gut morphology of these lizards would depend only on their diet, not their island of origin.
AiG said:
Thus, once again, this so-called “evolution” is possibly just natural selection acting on pre-existing genetic information, helping a population adapt to its surroundings. However, without knowing the exact genetic or epigenetic mechanism(s) underlying the change, we can’t determine exactly what is going on, biologically speaking.
AiG writer demonstrating her non-understanding of evolution? Natural selection can't act on
non-existing genetic information, can it?

Also, phenotypic plasticity is not adaptation. And natural selection acts on genetic variation. Of course, an individual can have a higher reproductive success for non-genetic reasons, but unless the trait causing the difference in reproductive success
is genetic, selecting it ain't gonna cause much adaptation.
Oh well. Considering that science news articles
outside creationist sources often garble basic stuff, I guess this isn't that bad...
AiG said:
More important (as Irschick said) is the speed of the changes, which reminds us of how quickly the original created kinds could have varied into the biodiversity we see today (interrupted by the Noachian Flood event).
Um, no, no,
no. You've just argued that the whole lizard incident is phenotypic plasticity. You can't have it both ways. If adaptation (which involves genetic changes) is limited, then mere phenotypic plasticity (which has to rely on the same old) is going to be even
more limited. It can lead to very rapid change (phenotypic plasticity, after all, can play out within an individual's lifetime), but no organism has reaction norms broad enough to include the phenotypes of distant relatives (what environmental conditions make a house cat grow lion-sized?). More importantly, such plasticity does not accumulate much over the generations. So, barring genetic changes, what you get in a single or a few generations is pretty much what you're stuck with for eternity.
Not to mention that if you think rapid "adaptation" (whatever you mean by that) can account for the current diversity of life from a small number of "kinds" (whatever you mean by that) in a few thousand years, you really have no grounds for arguing that evolution can't produce the same diversity in billions of years...
And where is the molecular data?
You know what? Go and collect it. Get a grant, get a lab, do some mapping, sequencing, functional genetics, or whatever you're interested in.
