Erm, that's
Scopes monkey trial, but no matter.

Microevolution is not evidence of natural selection as the cause of humanity. To prove the process of natural selection, you need to perform an experiment of natural selection, which would take lifetimes.
Not true. You can easily do it in the laboratory with viruses of RNA and DNA. Natural Selection has resulted in the "breeding" of a virus that was resistant to an amazingly high concentration of acid.

Natural selection occurs over countless years, not anything we could have possibly observed in our lifetime.
Natural selection occurs over a very large number of
generations. In order to see it in action you just need something that can turn over generations very quickly. Evolution requires natural selection but it also needs mutation. Mutation is easily demonstrated in the laboratory. Then you only need Natural Selection. But Natural Selection scarcely even needs any proof. That's why it has the word "Natural" in it. It is impossible to even conceive of a circumstance under which Natural Selection would
not occur, since all it consists of is "stuff that is fit to survive, survives" - which is a truism. If a mutation occurs that is harmful, the organism won't survive and the mutation won't be passed on. If it does, it will. The complexity that has arisen after trillions of generations is due to the fact that mutations don't water each other down or intermingle, they are
cumulative.

If you believe in natural selection based on observed "specization", you are making an assumption based upon the evidence that there were no external influences of the process over the eons.
Since there is no evidence for external influences (presumably you mean an Intelligent Designer), there is no reason not to make the assumption that there weren't any.

Given how long it takes for nature to produce a sentient being, it is absurd to call that assumption, fact. That might be okay to do when we are talking about insects becoming resitant to chemicals, but an issue such as this is too important to take on an assumption.
On the contrary, it is absurd to consider any other theory as fact, given the mountain of evidence and the fact that no new development in biology has thrown the smallest doubt on it. When Darwin proposed Evolution by Natural Selection, nobody knew about genes, nobody knew the mechanism of how characteristics were inherited, nobody realised that the way populations are distributed for a particular species was not necessarily random, nobody had the tiniest clue about DNA. That's just a small sample of the wide variety of developments in biology over the past 146 years, every one of which has bolstered the concept that all living things are related, and not one of which has put any doubt on the matter.

Life adapts to the environment, genetic mutations occur. Where is the observed cases from which we can see where the frog grew fur? Bad example, but I'm talking about the major changes from species to species. I'm not talking about a mouse with horns. Where are the trillions and more, of missing links? Can we construct a complete tree of life that distinctly shows each microevolutionary change? One that we can, without a doubt, put each species in its place, without guessing just because the fossils look similar?
Not for everything, but for some things, I'm sure that it can be done. In any case, evolution does not rest alone on fossil evidence. On the other hand fossil evidence does not
contradict evolutionary theory.
jayleew said:
Pure sciece makes no philosopical assumptions. Humans deduce reality from perception of evidence, philosophically.
Bottom line: We are here debating the absolute truth of evolution, when absolute truth requires that only science prove the theory. The problem is that natural selection requires science and philosophy to prove that it is the truth.
As I've hoped to show, this is not the case. Natural Selection does not require philosophy, but is in fact underpinned by a lot of hard mathematics. Life and death are absolutes, and NS cannot be avoided.
jayleew said:
Wherever philosophy is involved, there is going to be controversy and debate, and we can Google both sides of the controversy of this issue. Can anyone prove the process of evolution without using philosophical assumptions and deductions?
The fact that evolutionary theory is not simply "believed" but actually used in real life situations, from development of antivirals to the discovery of oil and coal fields, shows how ludicrous it is to pretend that, just because we are arguing about it here at the behest of the religious, makes evolution a "philosophy." It is not. It is a hard science with real-life consequences. It is not debated in philosophy seminars, it is
utilised in the real world. As the failed attempt to wipe out the Australian rabbit plague with myxomatosis proved, NS cannot be ignored or disbelieved in - it is a fact of life.
jayleew said:
We can use philosophy to make decisions to live by, deduce the truth, and argue with, but it cannot empirically prove a scientific theory. Logic and rhetoric can deduce the truth, but cannot itself prove the truth. Gravity is explained by philosophy and science, science alone cannot explain gravity. There is controversy wherever philosophy exists.
There is, in fact, plenty of empirical evidence which proves evolution by analogue. Scientific theory does not, in fact, require empirical proof to be regarded as "fact" or as near to fact as makes no difference. The theory of evolution is far closer to being considered fact than Relativity or the Quantum theory. There is no doubt that under certain circumstances those theories fall, since they are mutually incompatible. Those theories are known to be incorrect, and yet they are as near to fact as we can currently measure - for the large, with General Relativity and for the small with Quantum Theory. But there isn't
anything in the theory of evolution which conflicts with any known physical law, which again and again succeeds in explaining and predicting the facts of Life.
jayleew said:
Am I asking that you be unreasonable and not piece the puzzle together? No, I'm just asking that you not call the process of natural selection as empirical truth.
Something I have just done, frequently, and justified it every time. Now I'm asking you to stop lying about the theory of evolution. Even if that means that you stop lying to yourself.
jayleew said:
And that is the reason why we cannot teach evolution as undisputed fact. It must be balanced somehow, either at home or in school.
It is the best theory and the only theory that successfully explains every aspect of life, and does so without regard to the supernatural - which after all should not be taught in science class in any case. Please give an example of any
other field of knowledge in which it is required that, in the absence of empirical, repeatable experiments, there must always be two competing theories taught, no matter if one of them holds water and has supporting evidence and the other does not? Are you advocating that every Shakespeare class be balanced by a class which
only teaches that Shakespeare did not write his works? Are the schools to be split between Oxonian schools and Baconian ones? Or do they need every candidate for Shakespeare's authorship to be taught? Are we to teach in our schools that Neil Armstrong walked on the moon, showing all the film, artefacts, blueprints and actual testimony and then say, "There is a theory that all this stuff we just saw was faked and the astronauts are lying. You decide."

Since, not many professing Christians even read the Bible, how can we expect that the child is getting properly educated enough to make a decision about the origins of life when he or she becomes an adult? All we are doing right now in schools is training blind atheists or agnostics, since they are not perpared to discuss anything else.
Since they are not going to get a "proper" education as to the origins of life from reading the Bible, I think we expect that the child
is getting a "proper" education as to the origins of life by learning about everything for which we have actual evidence for. Not gradually, piecemeal, (first the fish, then the insects, then the larger animals) over a period of six days, a mere six thousand years ago. But a single life organism from which everything eventually descended, probably formed in a single instant, three billion years ago.
jayleew said:
And when they find out that there is controversy to what they thought was fact, they will second guess the theories of natural selection, just like what happened to me.
For people who actually use the theory of evolution to do their day to day work, from doctors to agronomists to petroleum geologists, there
is no controversy. Evolution is a fact, and we teach facts in school in science class.
The only controversy comes from people who can't let the Bible go. Having failed to learn from history they believe that faith in God derives solely from believing every word in the Bible to be the unvarnished truth, even though it can be proved wrong, ill informed and inconsistent on practically every page. There is a lot of good stuff in the Bible, don't get me wrong, and it provides what it is supposed to - a moral guide. Not a scientific treatise.
