so you believe that mutation and natural selection actually happen and it's
just the word "random" that offends you?

actually it has, just not directly in "realtime"

yep. Why not? What stops the mutations (whether random or not) from
continuing to accumulate over millions of years? Species boundaries? the
evolution of new species has already been observed. I'd love to point that
fact out to some creationist and have him not begin to back up the
taxonomic tree. Are you going to surprise me?

actually my understanding of "neo" Darwinism is that, drift and sexual
selection have been added to natural selection as mechanisms. Also, Darwin
(probably because of the influence of Lyell) believed that evolution was
always gradual. "neo" Darwinism includes the idea that it is only
*sometimes* gradual.

that's a straw man and not what I said. You just restate your opinion with
no supporting evidence. That's what makes it a mindless assertion. Even
Henry Morris tries to produce some evidence for his claims even if they are
all flim-flam.
