KIAMan - Mutation is one of many tools leading to genetic change on which selection and heredity can work. It is not the only one. Others include recombination, transfiguration, migration, system of mating, and random genetic drift.
Also isnt there some proof that all the different types of dogs come from one set of parent dog.
All dogs are the same species. They can all interbreed. That is why your phenotype (appearance) is not the classification used to define a species. For example, two bats can be visually indistinguishable but be different species b/c they won't interbreed.
xirtam - First you say and I learned the "accepted definition" of a species. and then you say Scientists can't even clearly agree on what a species is . If there is an accepted definition, which there is, then clearly scientists can agree on what a species is. Its defined by interbreeding without a high rate of sterility. Yes there are exceptions, but this is the widely accepted definition. To say its not is micharacterization. The following statement, btw, is not a point that I will refute, since it is a vague, unsupported appeal to authority:
My biology teacher told me that it was just what the book said and it was actually quite worthless because nobody really understands what makes something a completely new species
Also:
so-called "empirical data" is all fine and good, but since the scientists performing the research are also interpreting it under whatever light they want, it does me little "empirical" good. Seems like most of the scientific "evidence" I see proclaimed in the magazines has to be retracted later... see National Geographic articles on Archaeoraptor
Its not "So-called" data, it is data that has been published and reviewed in some cases for over 40 years in leading journals (Nature, Harvard University Press). Just b/c you are not willing to take anytime to look at it (and I posted specific references) does not mean it is irrelevant. The data is there for all to see, thats how peer review and repeatability works. Additionally, it is a good thing for science that things *can* been retracted. You point out one article. Hmm... lets see, there have been thousands of articles a year for over a hundred years on evolutionary theory. I'm sure cell theory and the theory of gravity had to have adjustments or retractions too. Thats the whole point of peer review. I would not dismiss Creationism *solely* based on the deliberate hoax known as the Pauluxy Man Tracks in Waco.
There isn't a mechanism preveventing accumulation of microevolutions from leading to speciations. I just don't see it when I look at the evidence, and I don't see the mechanism that causes microevolutions to amount to macroevolution on such a wide scale to explain the entire range of organisms. That's a jump that I don't think is supported scientifically.
Thankyou. Exactly. There isn't a mechanism. Bottom line. Likewise, there is no mechanism that causes microevolution to amount to macroevolution. There doesn't need to be since they don't differ in type, only in degree. There also are not "jumps." The evolutionary pathways are largely straight forward.
I just don't see much that indicates that I came from a tree shrew.
If I could show you evidence of this, that would be evidence against evolutionary theory. You need to understand, we had a common anscestor. We did not come from a tree shrew, and tree shrews aren't evolving to become human.
I've tried to get all my biology teachers to show me evidence that things can evolve from one species to another and that life can come from nonliving matter and that somehow a quantum fluctuation of energy can produce the universe
See, this to me is redirecting. Evolutionary theory is a process. It is not an origin, it is not an ethics system, it is not a philosophy. You're trying to lump the Big Bang, Evolutionary theory, metaphysics, epistemology, and all sorts of stuff all into one. No wonder you're having a problem with it.
it's the byproduct of random and chaotic chance, caused by an unguided and intelligent process.
Evolutionary theory is not a random or chaotic process. It is guided by relativefitness and natural selection.
Off the topic of hard science, you're using one of Aquinas' 5 proofs for God:
A being cannot bring about a cause without itself being in act. Thus you must have an uncaused cause.
I just want to point out that, not everything has to have a cause. You have not proved that the universe must have a cause.
Madrat - Yea, use the correct terms and then you would make more sense. 2 Phyla of the same species? What?
