"Punk Eek" is often used erroneously by creationists
to claim that "scientist
s don't agree that evolution
is a valid theory
". This is of course, bullshit
. It's not saying that a) evolution is disprove
n, or b) Darwin
was wrong. The hypothesis
suggests an additional, alternate mode of evolution, which occurs at a faster rate than the standard "neo-Darwinian
" model of evolution by successive small degrees.
The novel adaptation mentioned in the first writeup is often referred to as a "hopeful monster". Imagine a fish born with a skeletal deformity which gave it bony plates around certain vital organs. It could survive predation to produce more offspring than softer fish. Eventually, most of the fish would be hard-bodied. You would not find a complete range of intermediate forms between the original soft fish body and the "armoured" body, would you? Just a sudden appearance of "armoured fish"! It's a just-so story, but it illustrates the point.
