Butterflies fast forward evolution to evade death [ MSNBC ]
A population of butterflies has evolved in a flash on a South Pacific island to fend off a deadly parasite.
The proportion of male Blue Moon butterflies dropped to a precarious 1 percent as the parasite targeted males. Then, within the span of a mere 10 generations, the males evolved an immunity that allowed their population share to soar to nearly 40 percent — all in less than a year.
“We usually think of natural selection as acting slowly, over hundreds or thousands of years," said study team member Gregory Hurst, an evolutionary geneticist at the University College London. "But the example in this study happened in a blink of the eye, in terms of evolutionary time."
The scientists think the males developed genes that hold a male-killing microbial parasite, called Wolbachia, at bay.

Or it could be that God loved them and did a miracle. Right?

The lack of a rational explanation is not evidence for an irrational explanation. |

If the males with the gene existed before at 1% that means the gene was there. Natural selection is not evolution.

What a man believes upon grossly insufficient evidence is an index into his desires -- desires of which he himself is often unconscious. If a man is offered a fact which goes against his instincts, he will scrutinize it closely, and unless the evidence is overwhelming, he will refuse to believe it. If, on the other hand, he is offered something which affords a reason for acting in accordance to his instincts, he will accept it even on the slightest evidence. The origin of myths is explained in this way. - Bertrand Russell |

From the article:
| Other lab experiments indicated the males had evolved suppressor genes to shield against the parasite. |

It's not the main mechanism of evolution?
Elaborate. What is evolution? |

In response to Jerome's comment, that doesn't even matter pleco, although it does sweeten the pot a bit.
Part of evolution is a change in the distribution of a population for a specific trait. Evolution isn't solely about new mutations.

I think Jerome's worried about "new information" being generated. Sucks being him. |

No peer reviewed information. Anything a reporter writes must be correct. I will remember when we have other talks that this is your standard.

Evolution is defined to encompasses so many natural occurrences that many things are described as evidence of evolution. The problem comes when one needs to show the entire process. This can not be done, only inferred through faith.

No, it's not. Evolution is defined as a change in the frequency of alleles in a population over time. That's it. The definition is simple. What the consequences are of that simple definition are very complex.
But why shouldn't "many natural occurrences" be described as evidence of evolution? Evolution is natural, and it occurs all the time. There is no "unnatural" evidence for evolution, nor should there be.| The problem comes when one needs to show the entire process. |
What "entire process" does one need to show? Be specific.| This can not be done, only inferred through faith. |
Of course it can't be done if the "entire process" is just some nebulous thought in your head. |

Sigh. Knowledge can't get into your brain by magic, Jerome. You need to at least make an attempt at understanding things. You're going to remain ignorant so long as you continue to swat information away like a goalie defending a hockey net.

This reminds me of the ancient astronomers that would use their knowledge of a coming eclipse to control the masses.
