Not trying to recreate a closed thread, but... (Evolution)

I found this rather interesting: http://www.chicagotribune.com/news/nationworld/chi-0603070187mar07,1,6967465.story?coll=chi-newsnationworld-hed&ctrack=1&cset=true

So we are still evolving after all.

Here's the full article if anyone is so inclined (and has the biology Ph.D. it would take to understand it): http://biology.plosjournals.org/perlserv/?request=get-document&doi=10.1371/journal.pbio.0040072 (WARNING: It's long and contains a lot of crazy scientific stuff)

EDIT: If for some reason you can't read the first link (works fine for me, but whatever), here's the text:

Quote:
Genes show humans are still evolving

New York Times News Service
Published March 7, 2006

Providing the strongest evidence yet that human beings are still evolving, researchers have detected some 700 regions of the human genome where genes appear to have been reshaped by natural selection, a principal force of evolution, within the last 5,000 to 15,000 years.

The genes that show this evolutionary change include some responsible for the senses of taste and smell, digestion, bone structure, skin color and brain function.

Under natural selection, beneficial genes become more common in a population as their owners have more progeny.

Three populations were studied: Africans, East Asians and Europeans. The selected genes affect skin color, hair texture and bone structure.

The study of selected genes may help physical anthropologists explain why people over the world have a such a variety of distinctive appearances, said Spencer Wells, director of the Genographic project of the National Geographic Society.

"There is ample evidence that selection has been a major driving point in our evolution during the last 10,000 years, and there is no reason to suppose that it has stopped," said Jonathan Pritchard, a population geneticist at the University of Chicago who headed the study.

The findings are in Tuesday's issue of PLoS-Biology, published by the Public Library of Science, a non-profit organization.

I don't like it when people claim that humans in the future will be hairless because hair is a inefficient. That's not how evolution works! Unless hairlessness becomes incredibly sexy (or having hair became dangerous) for hundreds of years, we will continue our hairiness.

Human Brain size has increased considerably since the Dark Ages. Cant remember the exact value, but modern skulls are much larger, and the brain area is much bigger.

Mm. We've slowly been losing hair ever since we started wearing clothing, i.e. animal skins.

Eventually, as technology advances, the human race will be reduced to a bunch of pasty little fetuses inside mechanical exoskeletons.

Well, I know I'm not going to be popular in this thread since I do believe in creationism.
I'll just preface this by saying that I'm not an expert and I've not done any kind of extensive research into this topic.
This is just the opinion I've developed from the info I've gathered over the years from both secular and religious sources.

So anyway,
I don't see how this supports the theory of evolution [over simplistic explanation](that all life came from a single cell and evolved into the many species of birds, reptiles, mammals etc.)[/over simplistic explanation]
What is descriped there I've always heard refered to as "micro" evolution.
which evolution with a single species.
"Macro" evolution is the evolution from one species into another, like an anphibian becoming a human.

But just like others have said, this is hardly new information.
Changes within a single species such as hair length, height, dexterity, skin color etc. have been well documented and clearly seen for a long time.

Microevolution and macroevolution are different things, but they involve mostly the same processes. Microevolution is defined as the change of allele frequencies (that is, genetic variation due to processes such as selection, mutation, genetic drift, or even migration) within a population. There is no argument that microevolution happens (although some creationists, such as Wallace, deny that mutations happen). Macroevolution is defined as evolutionary change at the species level or higher, that is, the formation of new species, new genera, and so forth. Speciation has also been observed.

Creationists have created another category for which they use the word "macroevolution." They have no technical definition of it, but in practice they use it to mean evolution to an extent great enough that it has not been observed yet. (Some creationists talk about macroevolution being the emergence of new features, but it is not clear what they mean by this. Taking it literally, gradually changing a feature from fish fin to tetrapod limb to bird wing would not be macroevolution, but a mole on your skin which neither of your parents have would be.) I will call this category supermacroevolution to avoid confusing it with real macroevolution.

Speciation is distinct from microevolution in that speciation usually requires an isolating factor to keep the new species distinct. The isolating factor need not be biological; a new mountain range or the changed course of a river can qualify. Other than that, speciation requires no processes other than microevolution. Some processes such as disruptive selection (natural selection that drives two states of the same feature further apart) and polyploidy (a mutation that creates copies of the entire genome), may be involved more often in speciation, but they are not substantively different from microevolution.

Supermacroevolution is harder to observe directly. However, there is not the slightest bit of evidence that it requires anything but microevolution. Sudden large changes probably do occur rarely, but they are not the only source of large change. There is no reason to think that small changes over time cannot add up to large changes, and every reason to believe they can. Creationists claim that microevolution and supermacroevolution are distinct, but they have never provided an iota of evidence to support their claim.

Something I've never been ENTIRELY clear about:

What part of evolution (let's say, what overlying principle) is it that contradicts creationism in a way that causes creationists to argue against it? It seems like in general, the argument has just been "evolution is impossible, and this is why," and the specific parts of evolution that contradict creationism have not been emphasized.

I've always thought it was the "God created all things as they are" vs. speciation + old earth vs new earth, but many arguments seem to go far beyond just those two, and now I'm finally wondering if I'm missing something

So what you're saying is that there is a gene for wearing clothes. And that our hairy ancestors didn't get the ladies.

Ehh, no. The gradual loss of hair is an adaptation. Hair was originally meant for keeping the body warm. We started wearing garments. the body sensed the additional heat, and stopped growing as much hair, thinking it had too much.

Result = modern humans have less hair than, say, neanderthals.
Hey, if we wore skins over our heads for a million years, the norm today would be bald people.

Notice how mammals (who, I might add, usually don't wear clothes) are covered in hair or fur? Okay, except for whales and dolphins. But they have blubber. :)

As for the article on the Chinese guy, I've heard of that condition before. Yes, I'm referring to it as an abnormality because it is an abnormality, and could've killed him. Read the part about the infected ears?

the arguments always go far beyond that simply because the bible is decently silent regarding this.
It's generaly accepted that the purpose of the creation story is not to show how it was done but that is was done by God.
A friend of mine, who is a christian, is a science major has been dealing with this.
I don't know his specific scriptural resaons for this, though if you wanted to know I'd be happy to ask him. but he says that because God created everything that all proven science will perfectly line up with scripture because both are under the control and were created by God.

Many secular scientists say that, because of the theorys of evolution and the like, that the bible is proven to be just plain wrong despite these theorys often have just as many holes and unexplained aspects as the bible does.
This obviously doesn't make christians happy.
And you add to that how many christians don't know their bible as well as they should (I'm certainly at fault here) and rely on regurgitating what their pastor or some evangilist said but don't have an acctual understanding of the concept themselves.
And sadly, it's these christians who are often the most vocal or visible and even beyond the stereotypes that are formed, some other who hear them begin regurgitating what has been regurgitated by others who didn't fully understand in the first place.

So you can see that with this regurgitation continuing that very soon you have a large number of very loud people who have no idea what they're talking about but they think they do.
and if you try to point out their mistake, they will accuse you of not have faith.
And thus you have the rather sad condition of a large portion of the christian church today.

All that to say that alot of people who so fervently oppose scientific theorys and will argue to the death over it are doing more harm than good and don't accuratly portay what a "Biblical" christian should be.

Does that clarify anything at all?
I think I just got off on a rant here but the overwhelming principle in evolution that contradicts creationism is God's involvment.
Saying that it all happened randomly, on it's own for no acctual purpose contradicts the biblical teaching that it was all created by God for the very specific purpose that God would recieve the glory due his name through creation.

Anyway, Every response that I think of always leads to other things that seem like they need to be clarified which I guess is the reason that the arguments always go so far off topic.
Christianity has been discribed as water which is "shallow enough for a child to play in but deep enough for an elephant to drown in."
which is why these discussions are never simple.

Does that make sense?

It's possible God engineered the biological system and evolution is one process in that system and that he/she/it/they set it in motion long ago.

Most certainly yes. However, that would be along the lines of the idea that we are evolving now but doesn't settle the argument of origins.
Since the bible does say that God made man and the different type of creatures seperately (bird, fish, reptiles etc.) so the idea that man evolved from a lower form of life would contradict that.
I think it would be safe to say the evolution is occuring now and has been ever since God created life and it wouldn't contradict anything in the bible, that i know of atleast.
It's just the evolutionary origin that causes a problem.

Whoever wrote Genesis didn't have the scientific knowledge about biology we have now so he flubbed up -- there's nothing wrong with that as long as you don't take genesis literally. It's very understandable how people in the past came up with inaccurate explanations to describe things they didn't know about -- it happened all the time and the bible is not exempt.
