Lee Spetner believes that environmental changes can quickly drive speciation.

Of course, NDT does not allow the environment to be the driving fact, only a filter, but this news back his ideas.

The color of the critter was made to vary with temperature during its development.

I'm sorry, but I had to laugh as I read this. Because if color is evolution, is science going back to it roots of racism? Because it will be brought up that different color humans evolved differently. And when this happens, it will be asked on what level did each human evolve by color? And which color evolved to be more human. Did not science learn not to do this? I guess they can't keep out of their roots of what evolution has been used for, since day one.

I agree, it is joke that this gets referred to as evidence of evolution.

What's sad is that some poor soul will read that and think that they have really produced evolution in the lab, when all they have done is trigger something that relates to the color an organism.

I think perhaps Fox new has misunderstood, i.e. that animals can change outwardly due to temperature is nothing new:

e.g. Artic foxes, and rabbits change to white fur in the winter. It is even more extreme in the Crocodile and Melee fowl where the s@x is determined by the incubation temperature.

From the article

The color of the critter was made to vary with temperature during its development. The experiment reveals the basic hormonal mechanism underlying the evolution of such dual traits, the researchers report in the Feb. 3 issue of the journal


Seems as if they have uncovered an additional example of a temperature dependant trait.

Which leads to this avenue of research

Because the variations are based on temperatures, and thus in the wild would be dependent on seasons, the two types would tend to occur at different times of the year and may never meet in nature, he said.


So what they are really saying is that they have possibly found a cause of ‘population isolation’, and if you isolate populations, they don’t interbreed, and if they don’t interbreed, there is opportunity for speciation. Thus:

The next step, the researchers said, is to see if the variations do indeed occur in the wild.

Colour is an aspect of evolution, e.g. camouflage, or in our case, protection from the sun, in both these cases colour can certainly make you more ‘evolutionary fit’.

Racism is an extreme ‘social expression’ of tribalistic behaviour.

Tribalistic behavior? Was the evolutionists doing this as they killed aborigines?

And then took some and stuck them in zoos as animals?

There was even a book written about what happened.

And after being tormented, some even commited suicide.

You don’t have to accept evolution to see examples and consequences of tribal, or follow the leader, or illusions of grandeur, behaviour! Our history is riddled with such examples. E.g. wars, slavery, genocide. The excuses are many, and varied, but their root cause are usually greed, fear, and ‘protect the kin’ (the last example is what one considers kin, it could be as small a unit as ones immediate family, to something bigger, i.e. football team, nation, religion, race).

IMO... The posts are straying from the topic.

Maybe that straying diverts from the weak content (color change on an individual) of the latest evolutionist media splash.

Say, I lost my tan this winter. Could I be evolving. I'd better check my children. YIKES!! It IS inheritable. They are losing their tans too! More proof of evolution no doubt to the media crowd and their true evo-believers.

And this also diverts from the obvious fact that green-to-blank caterpillars have to do with descriptive biology and environmental impacts on individuals.

I sure would not want to defend this specific study as an example revealing anything about the powerful mechanisms that supposedly cause organisms to change so strikingly and permanently and that enables all variations of life to be descended from a common ancestor - - - if we mean real mud to man evolution.

The caterpillars are just another "headline evolution proof" that is neither a proof nor a headline - just a media looking for a story.

It's on a par with Darwin's use of dog breeding analogy (intelligently directed to favor unsustainable characteristics) to illustrate the power of his natural selection (undirected except towards reproductive sustainability in a wild/natural state).

While the study illustrates little about the mechanism nature supposedly uses, it does reveal a lot about the how easily those who want to believe are convinced about man-to-mud evolution without even challenging the weakness and irrelevancy of the content.

Sorry - I forgot to say thanks for posting this.

I was looking for just this kind of media item myself... because they are so predictable and newsworthy.
