You do not think survival and reproduction have anything to do with biological diveristy?
Do you believe the earth is roughly 4.5 billion years old?
Do you believe there have been mass extinctions of life on the planet?
Do you believe many forms of life present in the past are now extinct?
Do you believe that DNA holds the "information" necessary for various life forms?
[SIZE="3"]I can say yes to all your questions, plus throw in that I am certain evolution happened, but your list doesn't add up to E-theory. In the many debates I've had, it's virtually the only sort of response I ever get to the objections I
actually make to E-theory, which I will boil down to four points for you:
1. It is in the realm of possibility that random mutation and the various influences behind natural section can make minor adjustments to an extant organism (I refer to those minor changes as "simple adaption").
BUT, how do we know simple adaption developed the organism in the first place? (That is, it is equally possible that simple adaption is merely a superficial means to help an organism adapt to environmental changes, and was not the evolving force that brought the first single cell life all the way up to an organism.)
2. For an organism to pass on a trait to its offspring, genetic change must take place. So there is no doubt that genetic change is the "heart" of evolution (and in that analogy, according to E-theorists, NS would be the "brain").
BUT, how do we know what caused those genetic changes which resulted in organism-building? E-theorists say change is random (in the sense of not being consciously directed), but they can't demonstrate it really was random. (I don't mean to put words in Richrf's mouth, but this idea may be what he was referring to when he said "that which genes manifest from.")
3. Dawkins says it is a "travesty" that E-theory doubters claim the mesmerizing creativity that one finds in evolution is "random" (which, if you notice, I did
not say), and goes on to state that the creative aspect is contributed by natural selection (i.e., not by mutation).
BUT, no one has bothered to confirm that selection for fitness/breeding advantages alone would result in creative bio-structuring. (I mean, for example, if fitness were the only standard, why shouldn't tank-like things have evolved?)
4. And finally, if evidence is still needed to establish E-theory's evolving mechanisms (RMut + NS) as certain (at least as certain the fact that we've established life did gradually evolve), then
why are prominent scientists, like Dawkins, telling the public that evolution theory is "a fact the way the Earth orbiting the Sun is a fact"? It is misleading and a disservice to the objective practice of science, to claim an
entire theory is certain, when only gradual development, common descent, and simple adaption are effectively proven.
For a little more on my arguments, the last part of my answer to Aedes (#61) sums up my objections:

And my answer to ACB here (#82) reinforces my point that for thinkers like me it isn't whether evolution has occurred, but rather what caused evolution to occur:

As in most other debates I've had with E-theory believers, this one has gone the same way. No one takes on my objections directly, but instead E-theory believers accuse me of lacking a proper science education, provide grand theories E-theorists have for mechanisms that
might solve the problems (i.e., no actual evidence), ignore my objections and answer with what
is known (fossil, genetic evidence etc.), and if all that fails to shut me up, then nasty ad hominem barbs are sure to be headed my way.
But if anyone does manage to finally attempt an answer, it is something like what odenskrigare offered to my question "How do you know organism-building mutation was random," when he answered, "cuz what else would it be?"
Now there is an a priori assumption if there ever was one. Why is randomness allowed to be assumed in a debate where the vast majority of humans believe at least "something more" is behind life's development? If we infer from odenskrigare's tone in this thread, the assumption is justified because members of the "something-more" crowd are stupid (and so need not be taken seriously). Well, I say it's assumed for a different reason, and that is because the randomness/NS aspects of E-theory eliminate any need for a creator, and E-theorists are primarily physicalist/atheists. It is a mechanistic assumption, something, if true, a Godless physical universe could pull off.
In other words, that assumption suits a mechanistic/atheistic/physicalistic/scientism belief system . . . not the actual facts. I will add that as a science lover, I find it especially upsetting to see a group's belief system cause some of its members to not only violate the primary rule of empirical epistemology (objectivity) for personal reasons, but also violates the public trust, a public who wants to believe what is labeled "scientific" has actually been verified according to the rules of science. That life gradually evolved is a fact, but what caused that evolution is far from settled . . .
that would be the truthful statement to get from scientists.[/SIZE]
