New evidence for natural selection

by C1ay / February 23, 2006 8:59 PM PST

Charles Darwin would undoubtedly be both pleased and chagrined.

The famous scientist would be pleased because a study published online this week provides the first clear evidence that natural selection, his favored mechanism of evolution, drives the process of species formation in a wide variety of plants and animals. But he would be chagrined because it has taken nearly 150 years to do so.

What Darwin did in his revolutionary treatise, "On the Origin of Species," was to explain how much of the extraordinary variety of biological traits possessed by plants and animals arises from a single process, natural selection. Since then a large number of studies and observations have supported and extended his original work. However, linking natural selection to the origin of the 30 to 100 million different species estimated to inhabit the earth, has proven considerably more elusive.

Note the discussion of scientific proof, Clay.

"The odds that the association is simply due to chance are only one in 250, substantially higher than the standard confidence level of one chance in 20 that scientists demand."

Contrast this to many lay people's misunderstanding that something shown to 98% confidence "is not proven" -- a key element of the global warming debate.

Care to translate that to P-values Dave?

Remember your previous claims of P-values of 0.001. Still waiting for the links on that.

Lay people do NOT misunderstand. Often, rather, they are duped by numbers that sound more certain than they are.

I'm talking about your introduction of global warming into this here, not Clay's article.

if natural selection was at work we wouldn't have as many idiots in this world as we do Devil
