I recall hearing a scientific theory that there is a kind of meta universe with physics of its own, and that our universe came into existence when two other universes collided, perhaps like the formation of bubbles from soapy water. This is a model that describes a phenomenon resulting in the existence of our universe, without that phenomenon being intelligent. I'm not asserting that this theory is actually correct, but just showing that such models do exist. (I do recall that this model fit the maths quite well, actually, however it's not really testable, so I doubt we'll ever know anything beyond theory.)

"Humanity" refers to an abstract concept: that which defines what it means to be a human. We were in fact close enough in definition that I was correct to be confused as to how "humanity" and "science" are two parts of a whole. That is like saying humanity and hammers are linked, but humans are the dominant of the two. Science is a tool, not a symbiotic organism... To express the relationship between humans and science in that way is nonsensical.

This kind of relationship makes absolutely no sense for science and humanity, for the same reasons as described above. Humanity is the controller. Science is the tool. It is a tool that is used by humans to achieve the very same goals they would have without it, just more effectively. Quote:
Science never has "told the truth". The only thing you get from science are guesses as to how observations all fit together. These guesses are tested against further observation to make sure they are consistent, but that is all you can show for them. Science has never claimed to be more than that, and if you are criticizing it for being more, it is your own fault, and perhaps the moronic "scientists" who convinced you it was. Quote:

First of all, I have logically deduced that God is inherently incapable of being proven by science, unless he manifests directly in the visible world, and so I am confident that the rumors you heard are incorrect or that you misheard. I do not care where you heard them. I am not asking where you heard them. Now for your situation, you presented the fact that you were confused about an aspect of the theory of evolution. I told you that science has addressed it, that I had read an article about it a while back, and that, unfortunately, I don't recall which article it was. This of course is not meant to be any sort of evidence to support the theory of evolution. It was only meant as a notification that you can find such evidence online. It was never my intention to prove anything to you. However, today I'm feeling generous. I will look up an article for you. http://www.madsci.org/posts/archives...1026.Ev.r.html Finding that was as easy as googling for the keywords: chromosome number evolution. This is of course merely a description of the process as reportedly observed by others. If you would like scientific journals covering particular experiments, you'll have to find them yourself, as I have nother bothered with them since they're too technical for my knowledge of the field. If you would like further confirmation, you can find more documents, and perhaps even ask experts who may have observed these processes themselves. |

First, thank you for the informative link which specifically addressed the question. I apparantly had trouble finding the right search parameters. The ultimate answer it gave (inbreeding), however, is something I had already considered and ruled too unlikely, because it would be required in every case, and many animals don't have big litters of offspring. Every new level of unlikelihood pushes the evolutionary timescale back immensely as you know, and if gets pushed too far back then we don't have enough time since the Earth has been around.
This article demonstrates my point about assuming "Givens" though. You said: Quote:

Consequentially, "they" did not assume evolution in the sense of believing it arbitrarily, but rather as a temporary hypothetical situation. Furthermore, they did not do so to prove evolution, but rather to explore the logical implications of the model of evolution. If the model of evolution is accurate, then it means X, Y, and Z are true. That isn't what gives the theory its credence. The consistency that the theory has with observations gives those who understand this the confidence that they have the best possible information available when making decisions to which the theory is relevant. In no way does science ever guarantee that your expectations are correct. Now, to say "science and humanity are inseparable" is a strange way of putting it, but now that I understand what you mean, I agree. Of course, that is the case. Science is a construct built atop empiricism, a policy for deeming descriptions of observations as true, and logic, a policy for deriving truths from other statements already deemed true. Both of these are policies for defining truth, which would not be necessary if we were omniscient. In other words, science exists because we're nothing more than human. What is your point? Also, when I said that science is based on assumptions, I meant only these: the policies of empiricism and logic. Science requires no further assumption (except for hypothetical assumption, which is fine to do when exploring implications). If you consider observations and logic good sources of truth, but have something against the use of science, all that means is you misunderstand science, which you have shown several times to be the case. Could you please demonstrate your current understanding of what science is, so that we can at least come to agree on this? |

Also, about the whole "humanity" thing, sorry about the confusion. I used to say "mankind", but a PC English professor told me mankind was "sexist"(actually took points off for it!) and got me using that word instead. I need to stop doing that.

All the author of that article is saying is: Let there be a species A and a species B which are closely related descendents of a species P. Let B have one more chromosome than A. The question is, how do we determine which of the two, A or B, is the mutation, i.e. which differs from P in the number of chromosomes? Before I explain the method of deduction that the author presents, I will give a brief explanation of a concept in logic. In logical deduction, it is okay to assume something as long as you take that assumption into account when formulating your conclusion. Here's an example argument: Let's assume X is true. Given this assumption, we now know that Y is definitely true. The conclusion of the argument is not that Y is true, but that X implies Y. i.e. the assumption was taken into account by saying it implies the conclusion. Now, the answer proposed by the author is to take a collection of species, S, which are likely decendents of P and assume for the sake of argument that they actually are decendents of P. If this is the case, then you can look at the most common number of chromosomes in S and deduce that this is the most likely number of chromosomes that P has (since mutation in the number of chromosomes will be less frequent than retention). This means that you can determine whether A or B is the likely mutant, assuming you are correct enough about the descendency of the members of S. Now, it is not necessary that you be absolutely correct about every member for this method to be useful. Science lacks absolute precision, but certainty is not necessarily absolute 0% or 100%. In the above deduction about chromosomes, they made assumptions that everything in S was a decendent of P and then came to the conclusion of how many chromosomes are in P. If their assumption was false, this argument would be meaningless. However, evidence (not presented in the article, since this was beyond the scope of the article) shows that their assumption is probably correct, and thus the conclusion is probably correct as well. Confidence in the premise can be thought of as a scaling factor in the confidence of the conclusion. (This is expressed more precisely with math, but I'd rather adhere to common language here.) Quote:
Furthermore, it is useless in an argument to merely say that the basis of the other's argument is flawed. In order to actually argue, you must show exactly where the flaw lies, because if you do not see any particular flaws, then your claim that they exist is unfounded. Quote:
