Therefore, if the species survives, it is fittest, and it is fittest if it survives.

The definition of "the fittest" as pertains to Evolutionary theory is the the species that is most likely to reproduce.
quote:The fittest memebrs of a population are by definition the ones that reproduce the best. If certain variants don't reproduce any better than others, than we don't call them the fittest.
I suppose it could be rendered false if it were determined that the fittest creatures are not necessarily the ones most likely to survive and reproduce, bot a lot of good that would do Evolutionary theory.
quote:Sure it does. Your proposed tautological statement of natural selection says nothing about the transmission of genes. When you include enough information to fully describe the theory, it becomes much harder to formulate a tautological statement of the theory. It's not impossible though, because you can describe any theory as a tautology if you include the observations and inferences of the theory in the statement.
That's not adding anything to the equation, Matt.

[Edit} I didn't really answer your question. Ok, if an individual within a species is more fit than the others within the species, then its genes will have greater representation within the species. Now we're getting somewhere. [/qb]
quote:Natural selection explains the progression of the allele pools of populations. Individuals which are more successful will have a larger influence on the allele pool than individuals which are less successful. Over time, alleles that grant the best chance of reproduction will become more common in the allele pool of the population.
Natural selection is the process by which favorable traits that are heritable become more common in successive generations of a population of reproducing organisms, and unfavorable traits that are heritable become less common.
quote:Natural selection is the fitness function. Without natural selection there would be no way for a species to adapt to its environment. The random mutations introduced in one generation would have no influence on the next. The genetic makeup of the population would stay virtually identical. Natural selection is function that permits the adaptation of species. The random mutations in one generation may have a decidedly non-random impact on the reproductive capabilities of an individual. This non-randomness allows beneficial mutations to spread throughout the population over time because the individuals with those mutations will reproduce more often than those without them. Without this fitness function, species could not adapt at all. Darwin's finches would never exist.

If certain phenotype(s) are advantageous in your hypothetical constant environment, then they will tend to sweep to fixation (that is, they will eventually dominate the population until they are the only alleles present).

Yes, contrary to your preconceived notions, there are events that can very rapidly lead to speciation. Of course, when I say "very rapidly," I'm still talking in the order of thousands of years. But it's quicker than millions.

Otherwise, there would be no variation in the population at all- everyone would be a clone. And if that's true, then it doesn't matter what you get from Mom or Dad, because the end product (your genotype) will always be the same.

There are some loci in the human genome with more than a hundred alleles.
How do you propose that two, or even eight people carried all those alleles?

quote:There is nowhere near enough variation within the genotypes of two individual humans to account for the vast array of phenotypes we see in humans today. Even if Adam and Eve were each heterozygous at every single locus for different alleles (i.e. 4 alleles per locus), that wouldn't be anywhere near enough. Without mutation, your model implies that for any given gene, there are can be at MOST four different alleles. We know of individual loci with hundreds of alleles all by themselves. It is physically impossible for all of that variation to have come into being without some sort of mutation occurring.

Even so, I'm just going to say that I don't think mutations don't happen. This is the argument that is put out by Creationists: that the original two human DNA pairs were perfect, without any flaws. Therefore their children were born with perfect DNA, and so they could interbreed without worry about deformities. However, after the Flood the firmament which blocked so much of the harmful rays of the sun fell, and mutations began occurring with some frequency. One consequence that the Bible describes and might have been predicted by a theory based upon Creation-science is that within a few generations life spans would have been severely reduced, from thousands of years to no more than 120 or so.

Those gene sequence databases which you so casually dismissed in the previous thread have been critical to the development of modern biotechnology. Molecular phylogenies allow us to target genes that are evolutionarily conserved between humans and mice, so that we can test new therapies in the mice before moving into human subjects. If evolutionary theory wasn't true, then this approach would be fundamentally flawed, and we should be seeing the majority of human tests fail miserably as drugs that did the trick in mice either do nothing in humans or are actively deleterious. This does not happen.
Not only that, but you can show me what rockets can do, but you can't show me what Evolution can do (beyond varying beak sizes and moth colorings.)

A bird can carry genes needed for big beaks but not necessarily have a big beak. Lets pick a simply example.

Or would mutations that only take away data from the DNA do all that was required to explain the variations?

Tresopax, I know what the definition of a tautology is.

The reason they taught it to us was because the science teachers wisely realized that 12-year-olds would not understand the concept of electrons if they tried to explain actual quantum mechanics in middle school. We needed to be able to think of electrons in a more concrete way, even though electrons weren't really the way we were taught to think of them.
My point here is that science class is not sacred. There is no rule that we must strictly limit what is taught in a science classroom in any way. What really matters is that the students end up understanding what they need to.
Now.... whether Intelligent Design is something students need to understand is debateable. But, if your argument is that it shouldn't be in classrooms, one should not assert the reason is because "only correct science belongs in science class". That premise just isn't true. At least some nonscience belongs in science class - and possibly even some false science too.

Newtonian physics may be "wrong," insofar as we have since figured out that reality is more complex than his three laws, and that at certain scales those laws no longer provide sufficient accuracy. However, Newtonian physics as a model (i.e. as a theory) is still commonly used for everyday applications like architecture and industrial design, because the theory sufficiently approximates reality at that level.
