please provide sound, scientific evidence for design
But that logic only shows the plausibility of the assertion humans evolved. While I appreciate your efforts in explanation, I don’t think that actually answers my question: Does the theory of evolution necessarily have to assert that humans evolved? Or put another way, if a creationist said “I only object to the idea humans evolved” would that statement violate some law of evolution? I understand the evolutionist would argue that such a position is not reasonable to believe, but I guess I don’t see why an evolutionists should necessarily object to the statement since the creationist would not necessarily be challenging evolution altogether.Homo sapiens fits into the tree…
…In short the extremely high level of matching between the phenotype tree and the genotype tree and the fact the H. sapiens fits comfortably into that tree shows that the tree is real and that H. sapiens is physically descended from the same origin as all other life on earth.
Of course all species are unique, having attirbute that make it well suited in its existence. But the difference between humans and even apes is more than a varying degree of intelligence. There is not some small difference between man and apes, like between apes and other animals.All species are unique, not just man. Each species has the attributes it needs for its survival… We are specialised for intelligence, so we see intelligence as important… Intelligence is only one possible strategy among many.
Intelligence is not unique to humans…If something exists in an ancestor then it can be increased by evolution…The most intelligent land animals after us are the apes, which are closest to us in the Tree of Life. Intelligence is just another characteristic moulded by evolution to allow us to survive in our environment.
Evolution is a huge subject. For the Twin Nested Hierarchy in particular see this webpage. For evolution in general try Evo-Wiki or Talk Origins. If you want to try your local Library then I would suggest Ernst Meyer’s What Evolution Is which is an excellent summary. Of course there is always On the Origin of Species, though that does not cover areas such as DNA and genetics which were incorporated into evolution after Darwin.Your post is very interesting and I’d like to learn more about the subject.
Science does not prove its theories. Any scientific theory can only ever the best explanation we currently have of the available data. It is always possible that new data will require modification of the theory or replacement by a new theory that better explains the data.But is it really proof? Does it prove that humans evolved? Or could we not say just as easliy that it indicates a common creator rather than a common anscestor.
The American Revolution was a “singular complex event that cannot be repeated and tested”. How do we know that the American Revolution happened? We have documents from the time, just as we have fossils of early Hominids. The American Revolution had effects which extend into the present day, effects which we can observe. The evolutionary history of man had effects that extend to the present day and which we can observe. We have all the characteristics of apes, primates, placental mammals, tetrapods etc. We can tell that we are not descended from birds because we have none of the specific characteristics of birds.Aren’t we all limited to theories because the evolution of man, if it occured, was a singular complex event that cannot be repeated and tested?
Evolution is both a fact and a theory. The fact of evolution is “the genetic makeup of populations change over time”. This is a fact and has been observed many times. Every time a bacterium becomes resistant to an antibiotic or an insect becomes resistant to an insecticide we can see the genetic makeup of that population changing over time.That being the case shouldn’t we stop saying that evolution is settled fact?
I am Buddhist so “we Christians” does not include me. My scriptures are not your scriptures and my “higher truth” differs from yours. How are we going to decide which version of “higher truth” we are going to defer to? Are we going to split science into “Christian science” and “Buddhist science”? The power of science comes from limiting itself to areas where all can agree; scientific results do not depend on the beliefs of the individual scientist. The supernatural is an area where there is no agreement, and not even an accepted method of reaching agreement. It would be unreasonable to introduce such unresolvable disagreements into science.And, as ChrisW has said, shouldn’t we Christians defer to divine revelation as the higher truth?
As a balance, you may also want to consider a couple of other books, both of them excellent:I just started reading a new book called “Uncommon Dissent: Intellectuals Who Find Darwinism Unconvincing” edited by William Dembski… The book explains the thinking and patterns of the case in its first few pages.
As I’ve mentioned several times herein, the uniqueness of man is not limited to intelligence. However, I’ve had a difficult time communicating my thoughts on the matter, perhaps because man’s uniqueness is less than tangible.Intelligence is just another characteristic moulded by evolution to allow us to survive in our environment.
An interesting question; not one of the usual questions that come up in these sorts of discussions. It is certainly possible that there could be organisms that did not fit into the Tree of Life; I mentioned a pegasus. Any such organisms would be noted and recognised as exceptions. However if those organisms had descent with modification and competition for resources then those organisms would still evolve, so they would be evolving but on a completely different tree. We might expect life on extrasolar planets to be like that - evolving, but not part of our tree.But that logic only shows the plausibility of the assertion humans evolved. While I appreciate your efforts in explanation, I don’t think that actually answers my question: Does the theory of evolution necessarily have to assert that humans evolved? Or put another way, if a creationist said “I only object to the idea humans evolved” would that statement violate some law of evolution?

There is no compulsion, except the compulsion of the evidence. There is evidence that all known species did evolve, and no evidence that any known species did not evolve.Perhaps its an inrrelevent question, I don’t know. I’m just curious why an evolutionist, because he accepts the theory of evolution, neessarily has to assert that ALL living things evolved.
Here we will have to disagree. I can see no difference that could not have evolved. We are not as special as we sometimes like to think we are.But the difference between humans and even apes is more than a varying degree of intelligence. There is not some small difference between man and apes, like between apes and other animals.
This is simply not the case, though in the absence of a cogent counter-argument, it may certainly seem plausible. This is an old anti-evolutionary argument (Darwin discussed it in The Origin), and it’s been rebutted countless times in popular scientific literature. Of course, as long as one carefully avoids an in-depth study of these sources, one is able to confidently hold to such oft-refuted arguments as that from the eye’s evolution.How does evolution account for the evolution of the eye? The benefit is now obvious, but the purpose, clear up until the eye could see, cannot account for its development. For until the eye could actually see, it had no purpose.
The chances of me being aware of every argument made by anti-evolutionists and subsequently refuted by evolutioninsts, thereby ensuring I avoid reiterating them, is about zero, Don. If I thought I knew everything about the subject, I wouldn’t be in this discussion.This is simply not the case, though in the absence of a cogent counter-argument, it may certainly seem plausible.

I may look those up someday, Don, but do you realize how many books are recommended in these forums? If I read those books, someone else would pose yet more books to help me avoid my aparrently stupid questions. I come to these forums to explore, learn and test my knowlege. If I wanted to dive into some books on evolution I would do so and I wouldn’t be here discussing that very thing.Please—please—carefully read the books recommended in Post #145, which deal more than adequately with this point and others. Also, I’d get a copy of Michael Ruse’s Darwin & Design: Does Evolution Have a Purpose? (Harvard, 2003), as well as Robert Pennock’s Intelligent Design Creationism & It’s Critics (MIT Press, 2002).
Thanks. Contrary to popular opinion, I’m not just reading through a list of anti-evolutionist arguments…else I might make better argumentsAn interesting question; not one of the usual questions that come up in these sorts of discussions.
I see your point, and for you that may well be true (I don’t know enough about Buddhism to make conclusions). But technically, your statement should read “the evolutionist does not see any ‘scientific’ evidence” to the contrary, or something like that. I make that distinction because a theistic evolutionist, or in particular a Catholic evolutionist, by definition considers evidences beyond science or they likely wouldn’t be theistic. And there may well be non-scientific reasons for such a statement…I certainly think so anyway.There is no compulsion, except the compulsion of the evidence. There is evidence that all known species did evolve, and no evidence that any known species did not evolve.
I can only surmise from your post that you have perhaps simply skimmed this thread (at best) before posting. When you say that most people do not understand you seem to be putting yourself four-square amongst them. I recommend you go through an number of the earlier posts on this thread and several of the other recent evolution threads. When people make certain points regarding the scientific understanding of evolution, and if they provide a link to a resource, I recommend that you follow that link and read up on many of the useful resource links that have already been posted. You seem to have some misconceptions that I expect are already addressed elsewhere.Evolution is only a theory! That’s right, it is a theory because it is unproven. …
Most people don’t understand this thing about new species emerging or know that it’s never happened so I have no idea why they put their faith in evolution.
I really must have missed something then because I can’t agree with quotes like this. A species is something very tangible and not a manufactured scheme.And I’d add that it’s important to remember that the concept and inventory of “species” is not something handed down from on high, but is a manufactured scheme by humans, often before a true understanding of species’ relationships. We tend to classify how things look before we understand how they came to look that way. Some future, naive zoologist may well classify mastiffs and chiuauas as separate species, especially with only partial skeletons; but we, being witness to the evolution, recognize the gradual branches of the tree. I’d predict, though I don’t really know, that there are some extinct organisms classified as separate species that were later combined into the same species based upon more complete fossil or genetic information. So “one species changing into another” is really a meaningless phrase, since we are the ones deciding what makes a species. Even in today’s animal and plant kingdoms, it is very difficult to decide where in the tree a particular specimen belongs.
According to Nilsson and Pelger the evolution of a camera eye takes 364,000 generations. For a simple fish or worm a generation can be a year or even less. Half a million years is very short in geological time.But then consider the purpose of the eye. It has only one purpose…vision. It is an astoundingly complex thing, the eye. How long must it have taken to evolve (assuming for this discussion that it did). 100’s, 1,000’s perhaps even tens of 1,000’s of years or generations?
The purpose of the developing eye was to give the animal that carried it some sort of visual sense. Remember that to an eagle what we see it a useless fuzzy blur. Our eye is useless to an eagle, but it is sufficient for us. Just so, very simple precursors to our eyes would be useless to us but are still useful to those animals that have them. In Chapter Five of Climbing Mount Improbable Richard Dawkins gives an extended description of the evolution of different types of eyes, shows how those eyes developed and gives examples of animals which have those primitive eyes now. There are examples ranging from a simple patch of light sensitive cells, through cup eyes which add some sense of direction, to pinhole eyes which have some focusing ability, to camera eyes with lenses like ours.Well, until it fully evolved into a part of the body that can see, what was that orb growing in all those years of evolving beings? What purpose did the unseeing eye have during that lengthy process?
Evolution is an undirected process. It has no long term goals, all it deals with is the short term - how do I successfully reproduce myself? There is no “purpose” beyond that. Random mutation and natural selection are not directed processes, they do not aim at some long term target. Evolution has not been directed to creating anything in particular; there is no reason to single out any one particular species as the “purpose” of evolution. Since humanity is still evolving we could not have reached any such goal anyway. If there was an externally determined goal then evolution would stop when that goal was reached; it has not stopped yet.This is the way I view the uniqueness of man. The benefits are obvious, but the purpose of its development (outside of a belief in God) is not at all clear from my unerstanding of the evolutionistic standpoint.
Evolution is both a fact and a theory. See my post #143 in this thread or this webpage.Evolution is only a theory!
This is precisely the wrong way round. It is unproven because it is a theory. All scientific theories are unproven. Mathematical theorems can be proved, but not scientific theories. The theory of gravity is just as unproven as the theory of evolution.That’s right, it is a theory because it is unproven.
There are many examples of observed speciation. You can see the evidence here and here. Your source was in error on this question. You will not do well in your arguments if you use untrustworthy sources like this one. Even Answers in Genesis agrees that speciation has occurred, see here.But the second is that new species will arise from an established species and that has never been observed. Never!
If horses and donkeys are different species then how do we get mules in the first place? There are even very rare examples of mules that are fertile. Horses and donkeys have not quite separated completely, though they are very close to it. Similarly for lions and tigers which can still produce ligers and tigons. Both are good examples of the process of speciation as it is happening now. It is also instructive to have a look at the different examples of ring species. Species are convenient labels but they do not do complete justice to the variation present in the real world.Mules and ligers (lion-tigers) are sterile. It’s almost a contradiction, that an established species could create a new one. By definition, species are seperated by who and what they can breed with.
Again your source is in error. See the examples of speciation I referenced above, there are examples of new Drosophilia species given there. Please do double check what your sources say before posting it here. It does get rather tiresome refuting the same old creationist arguments again and again. The talk origins website has An Index to Creationist Claims. If I see an argument that I cannot refute off the top of my head, then I refer to the Index. If you want to be prepared for probable counter-arguments then you should look at it before you post - forewarned is forearmed. You would also do well to find a more reliable source, the one you are currently using has let you down twice.Scientists have dedicated huge resources to trying to create a new species. They’ve used drosphilia which has a generation of just a few days. Although they have created quite a lot of horrible mutations, no new species.
Your source was wrong; speciation has occurred and has been observed. Hence your argument fails. I see a mountain of evidence for evolution and I see nothing for YEC-style creationism.Most people don’t understand this thing about new species emerging or know that it’s never happened so I have no idea why they put their faith in evolution.
I may be the first on this thread, but I am far from the first to do so, see this webpage.You have come closer than any other evolutionist on this thread to acknowledging the above by stating that evolution is “theory and fact.”
There is enough evidence to show, beyond reasonable doubt, that man evolved from an ape-like ancestor. There is not enough evidence to show it beyond unreasonable doubt.I’d like to ask you to be more specific to see if we agree on this point: that the idea that man gradually evolved from apes is one aspect of evolution that is theory and not fact?
It turns out that the guy who developed statistical thermodymics, Boltzmann, was a Darwinist. Granted, evolution and the origin of life are two entirely different things, but it is pretty good evidence that thermodynamics doesn’t rule out increasingly complex structures in nature.What your link did not mention however, is that the second law of thermodynamics is a stumbling block to the answer that enough time makes anything possible and that Wald himself conceded this was evolution’s biggest hurdle.
Unlike evolution, abiogenesis remains to be definitively demonstrated. What do you know of the current evidence for abiogenesis?A hurdle that still has not been cleared.
Thanks for your answers, rossum. I thought I was being innovative in my question…Richard Dawkins gives an extended description of the evolution of different types of eyes, shows how those eyes developed and gives examples of animals which have those primitive eyes now. There are examples ranging from a simple patch of light sensitive cells, through cup eyes which add some sense of direction, to pinhole eyes which have some focusing ability, to camera eyes with lenses like ours.
I can understand your position, but I’d have to think even other evolutionists, if they are theistic evolutionists, may disagree with that. Scientists might observe what** seems** like random changes, but is there something that says they necessarily must be random? Who’s to say there isn’t a guiding force behind it (if the method is even understood properly)? That is not the same thing as saying there is scientific evidence which demonstrates that guiding force, but neither is there evidence that there necessarily isn’t.Evolution is an undirected process. It has no long term goals, all it deals with is the short term - how do I successfully reproduce myself? There is no “purpose” beyond that. Random mutation and natural selection are not directed processes, they do not aim at some long term target.
