Evolution Just Full of Hot Air

In Regards to NATURE, v. 428, 15 April '04, pp. 736-738,

"A lower limit for atmospheric carbon dioxide levels 3.2 billion years ago." Not too much here for us as far as I can tell, but any attempt to characterize the atmosphere during this imaginary time when, according to the myth, life was still in its infancy, is something we should keep an eye on.

And it does hint that there's still a problem with evolutionary excuses for ignoring the young, faint sun problem. From the abstract: "Climate models have focused on carbon dioxide as the greenhouse gas responsible for maintaining above-freezing surface temperatures during a time of low solar luminosity.

However, the analysis of 2.75-billion-year (Gyr)-old paleosols...have recently provided an upper constraint on atmoshperic carbon dioxide levels well below that required..." So they were still stuck with a freezing earth. The proposed solution was that other gasses made up the difference. These researchers found "iron-rich carbonate" in even "older" rocks indicating carbon dioxide levels were "several times higher than present-day values," but even so, "Unless actual carbon dioxide levels were considerably greater than this, climate models predict that additional greenhouse gases would still need to have a role in maintaining above-freezing surface temperatures."

Near the end of the report, the researchers say their results indicate that, if the current models are correct, "our modelling defines an unusual geologic environment" in which several minears "were highly unstable. On the other hand, if the Earth's near-surface and weathering environment...was buffered by near-equilibrium between [iron]-rich carbonate and common clay minerals, there is approximately two orders of magnitude discrpancy..."

That is, their data could accomodate carbon dioxide levels 100 times too low for the carbon-dioxide-greenhouse model, which would leave an awful lot of insulation to be done by other gases.

Evolutionists Admit Evolution is Impossible Part 6

OH! I almost forgot -- the report (and News and Views article) also notes that the same key gene also affects mice. This is interesting, as the supposed common ancestor would, as I recall, be placed back before the evolution of fish with fins, since both the ray-finned and flesh-finned supposed ancestral fossils appear in the same geologic levels. "Earlier" forms of fish fossils have nothing but spines (and thus were not as able to escape from Flood effects). In evolutionary terms, this is yet another example of incredible "conservation" of a gene.

More and more such cases are being discovered, and it will be interesting to see how many of these "living fossil" genes are in all of us. It actually seems to fit best with the "modular design" concept.

Evolutionists Admit Evolution is Impossible Part 5

The closing paragraph starts with: "One of the central mysteries of evolutionary biology has been the relationship between microevolution and macroevolution." Ain't that a gem?

Ready for a good hearty belly laugh? Keep in mind what I've noted above, then compare that to the conclusion here:

"Can an understanding of population-level processes explain major evolutionary events such as the Cambrian explosion -- the period around 550 million years ago when complex animal life took off? Perhaps so. Shapiro _et al._ might have discovered a smoking gun -- a real example of a type of macroevolutionary change that is produced by genetic differences between populations."

Okay, now that you've stopped rolling on the floor, there's actually a bit more I wish to share. The report itself, "Genetic and developmental basis of evolutionary pelvic reduction in threespine sticklebacks" (pp. 717-723) reveals that the primary hybridization -- were you thinking, as I was, that they probably came from neighboring lakes or something like that? -- was between "A wild-caught marine female stickleback from Onnechikappu stream (east coast of Hokiiado Island, Japan)" and "a wild-caught benthic male from Paxton Lake (British Columbia)."

Incredible! They've just proved that there's NO significant (evolutionary) difference between fish on opposite sides of the Pacific, even though one lives in the ocean and another in a lake, and they take this as evidence for evolution?!?!?

Oh, and in case anyone thinks it was some kind of fluke (uh, no pun intended), to check their results, they also crossed the Canadian lake fish with "Wild-caught Gjogur marine (Iceland)" fish and also obtained viable progeny for study. They also had success with fish from a lake in Iceland and also marine fish caught from a river in British Columbia (I take it marine sticklebacks spawn in fresh water as salmon do).

That these fish from different environments around the northern hemisphere can still be interfertile indicates that they have not been been evolving for over ten million years, but have suffered from a few mutations in under 10,000 years.
