Dredge writes: Please note that phenomena such as common descent, natural selection, sexual selection, mutations, genetic variations, inheritance of beneficial mutuations, gene flow, genetic drift, genetic recombinations, speciation, changes in gene frequenies within a populations are not "evolutionary theory" - they are observable facts and principles of biology. There has to be enough acidic irony in that quote to start a food chain. Tell me Dredge, is God anything like a theoretical UCA? I mean without any of the supporting evidence.

The problem is, there are different definitions of the "theory of evolution" and some of them don't include anything about macroevolution or UCA; they merely mention principles of biology that no one disputes.
For example, livescience.com offers this defintion:"The theory of evolution by natural selection, first formulated in Darwin's book "On the Origin of Species" in 1859, is the process by which organisms change over time as a result of changes in heritable physical or behavioral traits.". In this sense, "the theory of evolution" and "evolution" and "principles of evolution" (and "microevolution") all refer to the same thing. So on second thoughts, I'm probably barking up the wrong tree and should go back to my original "UCA" argument expressed in the OP. As far as I know, googling "practical uses for the theory of evolution" comes up with nothing. But googling "practical uses for evolution/priciples of evolution" produces many such uses. I find that interesting. Edited by Dredge, : No reason given. Edited by Dredge, : No reason given. Edited by Dredge, : No reason given. Edited by Dredge, : No reason given.

Dredge writes: The problem is, there are different definitions of the "theory of evolution" The 'problem' is that the ToE can be explained in several ways, which is actually not a problem, but a benefit.
and some of them don't include anything about macroevolution or UCA; they merely mention principles of biology that no one disputes. You'll find that religionists like you dispute all manner of things about evolutionary theory from nothing evolved at all (YEC biblical literalists) to evolution happened the way science says it happened but at some magical moment god interfered and stuck a pre-frontal cortex and a soul into an ape (Catholics) You might be surprised to hear that I completed two terms of degree level study of evolutionary theory without hearing the term "macroevolution'. It seems to be a distinction that religionists feel may provide them with a loophole while scientists simply say that “Macroevolution and microevolution describe fundamentally identical processes on different time scales”.
For example, livescience.com offers this defintion:"The theory of evolution by natural selection, first formulated in Darwin's book "On the Origin of Species" in 1859, is the process by which organisms change over time as a result of changes in heritable physical or behavioral traits.". In this sense, "the theory of evolution" and "evolution" and "principles of evolution" (and "microevolution") all refer to the same thing. Yeh, well who would have thought that the principles of evolutary theory come from the theory of evolution?
So on second thoughts, I'm probably barking up the wrong tree and should go back to my original "UCA" argument expressed in the OP. By the number of edits necessary in such a short post I can see you struggled with that, but still, congratulations, your ideas *can* be influenced by facts. That happens rarely with religionists here. As for UCA, that's been answered - the UCA is a prediction/conclusion of a simple interpretaion of the ToE. If you think of an 'imaginary tree of life, you would place the UCA at bottom of the trunk. But equally you could have a root system under it that works in the opposite direction - from many to one - which then forms many again. Other complexities arise with the probability of horizontal gene transfer between micro-organisms.
That's why it is usually referred to by scientists as LUCA (Last UCA). And to repeat, it doesn't need a practical use to be true. Knowledge is valuable. And interesting. Period.
As far as I know, googling "practical uses for the theory of evolution" comes up with nothing. But googling "practical uses for evolution/priciples of evolution" produces many such uses. I find that interesting. Having accepted above that the principles of evolution are derived from the theory of evolution, that's a retrograde step. However

As far as I know, googling "practical uses for the theory of evolution" comes up with nothing. But googling "practical uses for evolution/priciples of evolution" produces many such uses. I find that interesting. Understanding the internet and google, how they work, from where their data flows, this is not at all surprising. There are a lot of useless uninformed treatments in such a list of results. The key is swamping through the chaff to find the legitimately knowledgeable works, then, the hard part for religionist creationists, is reading, studying, comprehending that body of knowledge. I get the impression you don't even look at the results. You scan the titles, scan a few words looking for a bone to pick, but eschew the scholastic rigor of understanding the data and the concepts the various sources, in concert, seek to convey. That is being intellectually lazy. As a result you have no actual knowledge of the subject. You don't know what the hell you're talking about. Edited by AZPaul3, : No reason given.

This post of yours completely destroys any credibility you may have had.
Dredge writes: I doubt if ToE reflects reality as, for starters, it does a very poor job of explaining the many gaps, Good grief. What gaps are you talking about? Be specific. So, you are criticizing the Theory of Evolution because it doesn't explain everything? Really?
Dredge writes: distinct lack of transitiionals There is no "distinct lack of transitionals." Museums are packed with transitional fossils hundreds and hundreds of them. Thousands of papers and books are written describing new ones every year. That you would say this shows you have a distinct lack of knowledge on this subject.
Dredge writes: and sudden appearances of fully-formed organisms that are evident in the fossil record. Do you even think about what you write? In what reality would you expect partly formed organisms to be running around? Are you daft?
Dredge writes: Therefore a mere theory is not knowledge, as scientific theories come and go, as you well know. Right there you demonstrate that you don't know jack shit about any science. There are several different, unrelated ways that "theory" is used today. 1. A theory is a wild-assed guess, used by uninformed people like you, who don't know anything about science. 2. In science, a theory includes all the evidence, all the observations, all the facts about that field of science. As new things about that subject are learned they are added to the theory. If evidence is discovered that contradicts the theory or part of it, then the theory must be abandoned or corrected. Scientific theories can be used to make predictions. 3. In physics, hypotheses are often called theories even though they have not been experimentally confirmed. People who have studied science and understand how it works should know about these different usages of the word theory. The Theory of Evolution has stood for 150 years. There have been numerous modifications and corrections, but anyone who refers to it as a mere theory has no chance of refuting it.
Dredge writes: The fossil record is knowledge, but the theory of evolution that attempts to explain the fossil record is not knowledge. No, the fossil record is evidence that life has evolved over the course of history on this planet.
Dredge writes: And a belief, no matter how strongly held, is not necessarily knowledge. This is true. That is why science relies on evidence rather than strongly held beliefs.
Dredge writes: You may be 110% convinced that all life on earth evolved from UCA, but that doesn't qualify it as knowledge, as no one can demonstrate that it is the truth. You have been repeatedly told that no one is convinced that all life on earth evolved from UCA, because there is not enough evidence to make that conclusion. Why do you keep claiming that's what we think, even after we repeatedly say we don't? I know this is your favorite delusion, but to keep repeating it is just plain stupid. You have no credibility. Edited by Tanypteryx, : No reason given.What if Eleanor Roosevelt had wings? -- Monty Python One important characteristic of a theory is that is has survived repeated attempts to falsify it. Contrary to your understanding, all available evidence confirms it. --Subbie If evolution is shown to be false, it will be at the hands of things that are true, not made up. --percy The reason that we have the scientific method is because common sense isn't reliable. -- Taq

edge writes:
The "principles of evolution" are the (useful) mechanisms of evolution - mutations and natural selection, for example. Mutations and natural selection are observable, demonstrable facts - ie, they exist regardless of any scientific theory based on them, such as ToE. The (useful) facts came first, then the (useless) theory. So, let me get this straight. You don't think that the theory of evolution was useful in developing various 'principles of evolution', which ARE useful. Is that correct? Human beings have been making practical use of the "principles of evolution" in animal and plant breeding for thousands of years. They didn't need any "theory of evolution" to do so.

Every pamphlet with antibiotics warns you to finish the whole series. That is evolutionary theory in action.
Which "evolutionary theory" might that be? I thought antibiotics worked according to facts, not a theory.
