Good grief Les, surely you have looked at http://www.talkorigins.org/" . How could anyone who seriously studied the evidences exposed there say that the evidence for macro evolution isn't there?
I’ll tell you exactly why. Because the very best actual observed evidence is speciation, and speciation doesn't require organ development, as you must know. I am open to being shown the error of my ways. I’m lookin’ but I don’t see anything in evolution, proof-wise, except simple adaptation and speciation, and then tons and tons of speculation about how organisms develop by way of evolution.

The idea that only "superficial" differences are the result of evolution - what creationists call microevolution - has been well and truly exploded, and the evidence is out there for anybody to see. Consider the essay on http://www.talkorigins.org/faqs/faq-speciation.html" , for example.
Exploded? I can’t find the evidence at your links which proves organ development. Perhaps I’ve missed something, so if you see it please direct me to it. All I find is the same thing I’ve always found, proof of simple adaptation and no PROOF of organ development via natural selection and genetic variation. Lots of theories though about how it might happen.

And your comment that evolutionists will fall back on "What better theory have you?" is just a straw man.
How many times do you think I’ve heard it here? It’s one of the favorite arguments of scientism devotees. It’s no strawman. In fact, if you insist I will reproduce comments of PF members saying exactly that.
You know, I would love to see the evidence, because if I do I will revert to my former faith in evolution so fast you will have to admit I am not biased one way or another, but I am simply skeptical of claims that the evidence we have allows us to conclude natural selection and
accidental genetic variation has created organs and organisms.
If you look at the evidence, what you see is something like 3.5 billion of years of bacteria and algae, and nothing but. Then quite coincidentally (?) when the atmosphere had reached the proper proportion of oxygen, a huge burst of forms develop 550 MY ago. There is no logical explanation, and certainly no evidence, to explain why that would happen since we have all those conditions today and it doesn't happen.
Here’s the problem. We don’t see genetic variation
today in existing species that would allow us to believe in the sort of variation needed to produce the burst of organ development during the Cambrian era. And we don’t see a huge range of variation in environmental conditions either that would help nature “select” the array of modifications needed for an organ/organism to develop.
Eldredge documents the “punctuated” development and then acts as if that is just how evolution works. To me, that is so revealing. Why would one automatically assume a huge anomaly in the starkly uncreative march of natural selection/genetic variation we actually can observe today is “normal” unless one is already committed to explaining everything Darwinistically?
No, based strictly on the evidence of what we have observed happening in nature, and I mean strictly (you don’t get privileges with evidence because you are a scientist), the natural selection-genetic variation team is only known to result in superficial changes. That alone doesn’t account for either the speed of changes that occurred during the Cambrian era, or the quality of changes which resulted in organs and organisms where nothing like it before had ever existed. And it also doesn’t explain why it isn’t happening now.
One might cite the genetic record, and it does show most all of life seems related. But what it doesn’t show is what caused the genetic changes. You, as a devoted physicalist, don’t get to claim natural selection and accidental genetic variation is responsible for that until you can prove it since there might be another influence involved, and since you can't demonstrate it today.
So I restate my objection that scientism devotees are making claims which aren’t yet supported by the evidence in order to push their beliefs on children in the education system and the rest of us. As much as you hate the idea, God or whatever you might want to call universal consciousness, just might have played a key role in the origin and development of our universe.
