‘They are equating Adaptation with Evolution.’
Exactly. Adaptation is not evolution. If the guppies turned into Great Danes, then we’d see an example of evolution. Back to the drawing board...
ping for ya...put another pin in their bubble...
No you would be seeing magic dust!!
Steve Jones, on page 170 of “Darwin’s Ghoxt,” writes;
“Within a species, in different places selection may call for (or be offered) different mixtures of mutations to do its job and may come up with subtly different products. Quite often, one local blend does not combine well with others. Sometimes - as in the two inherited errors that jointly cause the smoky gray fur of the Persian cat - the nature of interaction is known, but more often it is not. If the failure of adapted mixtures to work together becomes complete, the populations find it impossible to exchange genes when they meet, and each becomes, in effect, a new species.”
