Michael Altarriba requested Windchy for information. Bold, trusting, but Not a good idea.
The Science article Windchy cites as his refutation of "macro evolution" opens as follows, "Overheard at breakfast on the final day of a recent scientific meeting: "Do you believe in macroevolution?" Came the reply: "Well, it depends how you define it."
And how to define "it" is the whole game Windchy and other creationists play. The conference at the Natural History Museum in Chicago was where Steve Gould and Neils Eldredge carried the day by convincing population geneticists that punctuated stasis was valid from a paleontological perspective. For the geneticists, this led to the realization that in natural communities selection could just as easily restrict variation as it could encourage it. The "Nature" in natural selection got much bigger.
The pace of evolutionary change was also reconsidered such that new species didn't require millions and millions of years to emerge, but to quote Gould from the meeting, "I'd be happy to see speciation taking place over, say, 50,000 years," said Gould, "but that is an instant compared with the 5 or 10 million years that most species exist." He followed up by mentioning "The point is one of the relative frequency of one process as against the other."
Creationists have, as always, lied about what "micro" and "macro" evolutionary changes are. In their usage, a microevolutionary change is any biological fact they cannot deny. They then insist that "macroevolution" is horses that fly, or vorpal clawed saber-toothed bunnies.
