@blloydb,
When you "responded" to my remark about creating doubt, you were engaged in quote mining--which is to say, you took a part of what i had said, and made a snide retort, while ignoring the entire statement, while ignoring that my reference to creating doubt had a larger context. The larger context was creating doubt about science, while not actually engaging in a discussion of the science to which you object, in scientific terms. That is rhetorically dishonest.
You have three "points" which you want discussed. You begin with "Incremental steps cannot explain biological systems." Oh? And you know this because? That is an
ex cathedra statement, a statement from authority, that is
ipse dixit--a statement with no proof, no antecedents, upon which you intend to base your subsequent statements. Another way of looking at is as a "have you stopped beating your wife" question. If someone attempts to answer such a question by a yes or a no, one has implicitly accepted the premise that one beats one's wife, or has done in the past. The only plausible responses are either: "I have no wife.", or "I have never beaten my wife." Anyone attempting to answer the questions which succeed this statement from authority on your part will have implicitly accepted that statement from authority. It is sufficient to challenge the statement itself, it is sufficient to challenge an assertion that incremental steps cannot explain biological system, without being obliged to answer any questions which proceed from that statement.
Next, you state: "We've never been able to morph one species into another." Yeah . . . so? Who here has claimed that a theory of evolution predicts that one can "morph" one species into another? The basis upon which Darwin based his exposition of a theory of evolution was morphology. It was sufficiently robust that Wallace had also come to the same conclusion, and that both Darwin and Wallace were able to extrapolate the theory. That does not mean, however, that morphology is the only basis upon which a theory of evolution is founded, nor does it mean that falsifying statements which you make about morphology constitute a scientific falsification of a theory of evolution. There are at least two bases for declaring that speciation has occurred. That is the ability to reproduce reproductively viable offspring,
and sexual isolation. So it is entirely possible that two plants or animals which are justifiably considered to be separate species could possibly reproduce a reproductively viable offspring, but they are still separate species because they are sexually isolated from one another--they are geographically separated.
Since Darwin's time, a theory of evolution has been supported by and refined by genetic studies. A theory of evolution does not rely solely on morphology, and in fact, morphology can be a false path. In another thread, Roswell introduced the subject of teosinte. Teosinte is the Mexican grass plant from which maize, or if you prefer, corn derives. Below is a picture of teosinte (on the left) beside an ear of maize in an early primitive form (the early primitive form of maize was reconstructed by crossing teosinte with an ear of Argentine popcorn, and then selecting the smallest ear):
You can read about the domestication of maize by clicking here, which will take you to an article by Eve Emshwiller, Ph.D., an Abbott Laboratories Adjunct Curator of Economic Botany, in the Department of Botany, at The Field Museum of Natural History. A point upon which you might be prepared to heap derision is that teosinte was crossed with Argentine popcorn to produce the ear of corn which resembles early maize. But it raises a significant point about morphology. It was by studying teosinte genetically, and by successfully crossing it with modern forms of maize that scientists came to the realization that teosinte and maize are members of a single species. The morphology alone would decree that although they may be related, they are different species, but genetics and successful cross breeding demonstrates that they are the same species. So, your statement from authority about "morphing" from one species to another is meaningless.
This is your third "point"--"Life is very robust in maintaining its genetic integrity. Mutations often end in disability, illness, death or inability to reproduce - never it seems is the mutation beneficial. Oops - I'm setting myself up here (I'm learning about you A2K lot) Before you find an example of a viral mutation that helps the virus in its mad reproduction ... I mean mutations in large multi-celled organisms - I'm talking cat, dog, cow, human, big stuff." Is there question in there somewhere?
