Not surprisingly, getting immature responses from atheists. :)

I was trying hard not to derail the thread. But it's quite impossible when someone comes along saying don't read anything, it's all a trick, chuck in a coupla quotes of the bible, trick of the devil yada yada.

Man, do yourself a favour and at least read a wiki article or something. Godidit doesn't hold up outside the playground and it won't work in here either.

Use it, don't use it.

now can we IP trace that person and ban them for obvious trolling?

i thought it may have been a troll but i genuinely have met people that believed that kind of thing

No, Swa, that is not true.

There are more examples but you can Google them yourself.

Now, if you're expecting us human beings to observing changes amounting to the difference between, say, cats and dogs, within one lifetime you're being unrealistic, as that level of change simply does not happen within 70 odd years. Hell, some species remain in relative stable equilibrium for millions of years with very little changes to their anatomical structures.


Please provide reference for this claim. I know some biologists and this is simply not an issue.

Really good post.

Most of us are on dynamic IPs strikes me as a bad idea. I can't stand it when I visit Wikipedia and it tells me it is very angry with me for performing troll edits on it's articles. Has happened a few times.

First set of posts in this thread and the idiocy was extreme and insulting. I'm guessing the sockpuppet of some childish member wanting to fsck with everyone.

They can go believe it somewhere other than the science section.
Well said. I hope this doesn't become a habit. I certainly don't want a post and member duration limit imposed on this section too.

Starting to see a terrible pattern of combative creationist threads in this section. I hope it doesn't continue as I always enjoy coming to read the articles presented in this section even if many of them are over my head :p

Actually, in this section, it would make more sense to me. Very few posters actually want to post science here. I'm all for herding the down-with-evolution folks to PD.

So in other words, make it even more of a dumping ground for this kind of silliness? :p

+1.

Creationism belongs in PD, not here. It isn't science.

So the central question of A CONFERENCE is micro- vs macro-evolution. Funny to have a conference for something non-existent, can explain why scientists never get things done. The second sentence is even more profound.


[Reznick, David N., Robert E. Ricklefs. 12 February 2009. Darwin's bridge between microevolution and macroevolution. Nature, Vol. 457, pp. 837-842]
Darwin found something that doens't exist as a problem for his theory? :wtf: But let's just carry on...


[Steven M. Stanley, Macroevolution and the Fossil Record, Vol. 36, No. 3, 1986, p. 460. (emphasis added)]

[Steven M. Stanley, Macroevolution: Pattern and Process. San Francisco: W. M. Freeman & Co., 1979, p. 39.]

Anybody noticed the bolded parts? Strange that macro-evolution is not only a creationists invention but it's also used to name science articles and books. Can we now finally get an admission from these zealots that there is a real and scientific difference between micro- and macro-evolution?
It is pure arrogance to simply assert the issue of micro vs macro evolution is not a complex issue. Of course it is.

Typically, micro-evolution deals with intra-species changes or variations while macro-evolution deals more with speciation events, irrespective of time scales. Some speciation events or macro-evolutionary changes may occur fast, others slowly. But therein lies the rub. You can't really make sense of the concept of speciation and/or macro-evolutionary change without a proper and coherent definition of "species". This has been pointed out before. There are at least 24 different concepts of species and depending which view you take, some evolutionary changes would qualify as macro-evolution while others as micro-evolution.

It is clearly a complex issue, any person that claims otherwise should at least familiarize themselves with the literature before making such arrogant statements.

Oh Odin here we go again with the definitions. :rolleyes:

I'm not ignoring religious crap in the Natural Sciences section. Stop discussing religion in the Science section or I am reporting it. This is not the place for religious stuff.

End. Of. Discussion.
Well there you go then. Take a big look in the mirror to see who brought what you call "religious crap" into this discussion. If you want to report stuff report your own freakin' posts and that of your fellow religious nutters. What's so bloody hard about that to understand? The atheists are fueling religious discussion so if you don't want it just STFU yourselves. Or as I said ignore it like a sane rational person would do but stop treating your "science" like a damn holy cow. :rolleyes:

Don't think I ever did so that isn't a problem for me. Go logic go!!!
Fine then, we are in agreement it's unproven. Hence possibly and even probably untrue.

Not when you understand what a scientific theory is. Go logic go!
Never had a problem with that. Theories are just theories, not necessarily truth. Nothing hard about that to understand at all. :)

You are teaching children that scientific theories are about proof? Please stop teaching children about things you don't understand then. You are ruining young minds with garbage.
Luckily they're not being indoctrinated that unproven **** must be the truth. Go logic go! :p

I wonder what proof you would like? What would be acceptable to you? Obviously words are not enough because there are many examples but it seems like anyone who says the fossil record is proof enough seems to have some other agenda to you and your agenda loving people. For example in The Greatest Show on Earth, Prof Dawkins repeatedly states evolution is fact and backed it up with examples.

Why is he not to be believed?

Well I know, and I'm sorry to mention it Porchrat because this is fundamental to the debate. but it's his lack of faith that discounts him immediately.
The fossil record IS NOT proof. Read what your own bloody experts say. The fossil record is just compatible with evolution like it is with special creation. So if THAT is your big proof for evolution it's just as much proof for creation. And if Dawkins claims evolution is fact and I presume he's not just talking about mutation but also the ToE then he's making unscientific claims. Rather than some religious dogma read what the real visionaries of science have to say. Just in case you are confused they are ALL firm believers in evolution but they don't claim that it's fact or proven because they know it's not and that any such claims are unscientific.

You probably avoid him like the plague. And if you don't, I'd love to know why you disagree with his statement that evolution is fact. Again, is it not easier to read a book than spend your life quote mining to 'prove' your own jaundiced theories?
Here you discredit yourself completely. There's no such thing as a "quote mine." It doesn't exist. Get it? Good. Now with that out of the way you're probably confusing it with quoting out of context. Learn what that means and you'll see your allegations are all imaginary.

You mean it's not true or you don't believe it's true? It's not clear if you think those two examples are good ones as you put them at the bottom. You should read up on the species problem. Also the "nylon" eating bacteria is not universally regarded as a good example of macro- or even micro-evolution. You are welcome to discuss these in another thread though as I don't want this one drifting too far please.

Now, if you're expecting us human beings to observing changes amounting to the difference between, say, cats and dogs, within one lifetime you're being unrealistic, as that level of change simply does not happen within 70 odd years. Hell, some species remain in relative stable equilibrium for millions of years with very little changes to their anatomical structures.
Not what I am expecting. The fact of the matter is that even the slow changes observed is more and more regarded as not being enough to account for the diversity of life. And yes even in 4 billion years that's why some biologists like Gould postulated punctuated equilibrium.

Please provide reference for this claim. I know some biologists and this is simply not an issue.
No references needed. I've proven the point that there is a difference not whether there's an issue or not.

Yes, you go believe whatever you want. It's a free country. Just don't try and force your beliefs on me.
Geriatrix, the way these religious idiot are acting you can't blame people for being so hostile. More than anything else it's these acts of ridicule against people with other beliefs than them instead of providing evidence for the claim that convinced me it's a lie. Nobody is trying to force their beliefs on you so that's an unfair criticism to make. Indeed atheists are the ones forcing their beliefs on us and our children so I would expect some hostility as not only natural but warranted.

Um, Techne is arguing that Swa should reconsider his position, no?
My position is that there's a difference between the two. Seems to agree with that and even that it's not a simple issue but a complex one. It's discussed at length between scientists.
