Beagle writes "The science of evolution is often misunderstood by the public and a session at the recent AAAS meeting in Boston covered three frequently misapprehended topics in evolutionary history, the Cambrian explosion, origin of tetrapods, and evolution of human ancestors, as well as the origin of life. The final speaker, Martin Storksdieck of the Institute for Learning Innovation, covered how to communicate the data to a public that 'has such a hard time accepting what science is discovering.' His view: 'while most of the attention has focused on childhood education, we really should be going after the parents. Everyone is a lifelong learner, Storksdieck said, but once people leave school, that learning becomes a voluntary matter that's largely driven by individual taste.'"

Ma Nature is a wasteful parent? (Score:5, Interesting)
Ma Nature just doesn't care about the waste. Of course the anthropomorphism just obscures things more, but the basic thing about natural evolution is that anything goes--but almost all of the changes lead directly to death. Ma Nature's approach results in vast numbers of tiny variations of the same basic forms that are all scrabbling for survival in a tiny niche. She isn't betting on the existence of a benevolent mutation. She just doesn't care.
Lately I was thinking that one of the weirdest aspects is that things worked out so that every one of us humans is a unique permutation. It would be 2^46 possibilities if you just started with one set of distinct genes from the chromosomes of a single mother and father, but there are so many variations for each of the genes that the actual number of potential human beings is vastly larger than that. Insofar as our genes contribute anything to the situation, each of us could be uniquely suited for some niche on earth. Talk about over-engineering?
Of course the likelihood that we'd ever find such perfect niches is pretty much negligible--but again Ma Nature doesn't care. If we wipe ourselves out in our frustration, she'll just start over again with the surviving cockroaches. So have a nice day.

Take by analogy a genetic algorithm to find some solution to a problem. Combining only the best solutions will make you fall into a local minimum and stay there. You have to keep some of the worse solutions in your set of candidates to break out of it. Similarly in real life, creatures with undesirable traits still survive and breed -- and I'm sure that that, even if simply by sheer coincidence and only in a small number of cases, leads to ultimately desirable traits in some circumstances.
How About Focus on Evolution? (Score:5, Insightful)
The speakers spent most of their time discussing why Intelligent Design is wrong, and getting into semi-religion-bashing. I heard nothing about any of the things that the summary to this article mentions, for instance, which was actually something I wanted to know more about. I'm not very familiar with all of the specific evidence myself (I'm not a biologist).
Now look -- as a scientist, I can completely respect and agree with the fact that ID is not science, for a multitude of reasons. But look at it from the point of view of someone "new" to science that was curious -- they showed up to an event, hoping to learn more about what evolution is and understand the "debate", and all they heard was how Creationism is wrong and how we need to fight religious groups and educate the people about the truth. "Educate with what?", that person will ask. "They haven't given any proof yet, and just seem to talk about how much they hate religion when they get together.". THAT is what the average person sees, and it doesn't really make scientists look good, and gives ammunition to the people that spread misinformation about evolution. Will that person ever go back to an evolution talk in order for us to clear up misconceptions? Probably not; forever, that person will now think "Wow, Evolutionists are crazy, I'm not going to that again.".
There's other issues of course, but the public image of an evolution scientist right now needs to be cleaned up before many will even bother to listen.

This has some big consequences.. that recursion would mean that whatever was a common ancestor would need a common ancestor,, all the way down. and perhaps plants and animals are fundamentally different arising from different organisms, and a few trunks might appear for bugs, fungus, and bacteria..
By choosing traits carefully, a phylogeny was developed, which related animals to each-other.. strangely this worked really well.
Anyway, evolution predicts that there is a tree structure, and that endpoints dont cross over.. so mammals dont get 4 chambered lungs like birds, but might still have some egg laying abilities like reptiles. Not should we see the octopus eye structure in humans. or bug armor on birds. Armadillos will have armor from keratin like a rhino horn, or fingernails.
Anyway, once molecular biology and sequencing came out, it solidly backed the theory.. Phylogeny people have been re-mapping the tree, bacteria took some serious adjustment, larger organism less so.
Now there is a push to generate "ancestral genomes" so that we have an idea of what the predecessor organisms were capable of... and where some of the novel enzymes popped into being. So enzymes which appear to be adaptation from our last ice age might be related in some way to survival of the cold, or eating rodents without GI distress. But with some timing, and some idea of the climate, the flora, and fauna some good guesses can be made as to why a subtle change might have happened.
So evolution theory may help in figuring out why humans stopped making vitamin C, and rats never need a vitamin C pill or fruit in their lifetime.
Or it can confirm things that we might already have guessed.. that humans make less stomach acid during pregnancy might be an evolutionary adaption to morning sickness.. because most pregnant women don't seem to have chronic bulimia problems, ie rotten teeth, esophagus ulcers, which would occur at higher acid concentrations. anyway, once they find the control mechanism I'm betting that it'll point to roughly the time when we started bipedalism.
Yes evolution is science, it does matter, knowing the history of automobiles lets us understand why tempered glass isnt appropriate for a windshield. Knowing the path that our ancestors evolved with lets us know what we should watch out for when we start tinkering.

In my studies, I read the Bible in Hebrew and Aramaic and Greek (with help of course) and learned that many things that are said in English are either out of context or blatantly wrong due to translation and just plain *HUMAN* error. Yes. The original Christian church showed me all of this in theology classes. The Church didn't seem to have a problem telling me that "P" and "J" and other sources wrote down the Old Testament and that Moses was looooooong dead by then. Or that the English "7 days" in Hebrew really meant "a long time." Among other things.
The Roman Catholic Church does not say that Evolution contradicts religion. In fact, the Church even explicitly said it had no argument against Evolution and that science is just fine.
It appears to me that it's the Fundies/Literalists with their King James translated Bible and absolutely no theological training whatsoever that are coming up with this Religion vs. Science debate. There isn't one. The writers of the Bible "the Jews" don't even have a problem with it.
Oh, and I hate to break it to you, but Jesus isn't coming again. His second coming was his Transfiguration (after he rose from the dead). It's just that the Fundies/Literalists don't even bother looking up "Revelation" in a dictionary. Revelations is basically another story about Christ *in the past* but written with a lot of religious symbolism. No prophecies.

They discuss that, and agree with you. The reason is that in the eyes of the public, the two are regularly conflated, especially by religious hacks trying to dispute evolution. So, they discuss the relationship and lack thereof (they're not completely unrelated, actually), and also discuss why they're talking about both.
The short answer is that they were trying to summarize the current state of scientific knowledge as relates to a particular political and religious debate, and both evolution and the origin of life are part of that debate.

"'Evolution is a theory about the origin of life' is presented as false. It is not. I know many people like to recite the mantra that "abiogenesis is not evolution," but it's a cop-out. Evolution is about a plurality of natural mechanisms that generate diversity. It includes molecular biases towards certain solutions and chance events that set up potential change as well as selection that refines existing variation. Abiogenesis research proposes similar principles that led to early chemical evolution. Tossing that work into a special-case ghetto that exempts you from explaining it is cheating, and ignores the fact that life is chemistry. That creationists don't understand that either is not a reason for us to avoid it."

Essentially, in

and with
b. the right soup of lots of different common and chemically combinable elements trapped together in a gravity well,
you get the preconditions for randomly occurring structural and process experiments.
Some of these randomly occurring but probable-due-to-the-regime-and-the-ingredients experiments
end up making structural and process fragments that alter/interact with/use their environment in such a way as to
incrementally, or in some cases dramatically, increase the probability of a similar structure or process
fragment recurring nearby in time and space to the first one. This is already a positive feedback loop.
Eventually, by chance, some cluster of these self-probability-improving structure+processes, a cluster
most likely made of smaller self-made-more-probable structure-process fragments, reaches a threshold
at which its robustness leads to a probability of 1 of structure and process like that existing in the general

Pattern self-preserving functionality transcends pattern occurrence improbability.
Call it stochastic evolution transforming into classical evolution.

Huh? Explain, please.
Most people today think that there is only one type of matter and that the complexity of life is just due to this matter acting like a very complicated machine. They would hold that if there is a soul it is separate from this world. A philosophical zombie would not work in this second view not because the matter has not taken the 'magic' form, but because no soul in the parallel world has attached itself to normal matter in this world. This is a view made popular by René Descartes.

Why would we need to push "earth orbits the sun" on everyone outside the context of science? Science touches upon every area of our lives, and we are generally screwed if we don't have a population with a reasonable basic general education. A basic overview of biology needs to be covered in highschool just as much as a basic overview of chemistry does. Biology without evolution makes as much sense as chemistry without the periodic table of elements.
Going on to college to get an education as a doctor, or countless other professions, pretty well first requires a foundation learning elements and evolution and more.
There is something seriously wrong if a medical school has to teach fractions and other remedial math. There is something seriously wrong if a medical school has to teach atoms and other remedial chemistry. There is something seriously wrong if a medical school has to teach the evolutionary tree and other remedial biology.
And even then, they don't need to discount other accountings
What do you mean "discount other accountings"?
Do you mean like "discounting" the sun going around a motionless earth accounting of the solar system? And "discounting" the four element earth-air-fire-water chemistry accounting of chemistry?
If that is what you mean, then yeah, the general public rather should have enough general education to be aware that such "accountings" have been completely discounted.

As soon as we learn a model for the world, we want to actively support that model. We emotionally invest. Few of us have the capacity to re-examine that model constantly. Sometimes, overwhelming evidence will cause a sea change in certain groups' world view, but generally we like to stick to our own.
Some people have a world view that includes a just and active Christian God with a book that explains the way the world works; any evidence to the contrary is dismissed out of hand and any evidence to support it is grabbed on to no matter how irrational. Some (a few) people are just the opposite: they would dismiss any evidence of a deity and hold fast to any seeming contradiction in dogma, no matter how badly translated. I'm in the later group, and I dismiss out of hand anything anyone says about the existence of any god. I'm prejudiced that way, for better or worse.
But simply trying to explain things to the parents will probably not make any great inroads in society. Perhaps, but probably not. More likely, you'll get a group of 10 people pissed off and they'll have nothing better to do than to repeatedly call your boss/underwriter until you are forced to go sell hot dogs on the street for simply suggesting that we should all get along and that no one should be nailed to anything for it.

While this link more or less covers these points I'll summarize as it's a lot to slog through. The fossil record is sorted based on time. Radiological dating coupled with clear evolutionary progress as you look at progressively higher layers proves this. If much of the life on Earth died in a flood then you'd expect to see sorting based on density, size and swimming ability with the metal and stone tools of the time at the bottom and a spectrum of animals ranging from big slow creatures that couldn't make it to higher ground and live longer or swim very well on top of the tools and birds, bats and things that can swim for a long time at the top. Considering that the remains of tools are all well above the likes of T-Rex skeletons this is clearly not the case.
The Grand Canyon is pretty much a poster-child for modern geological theories. It's layering is not consistent with a rapid flood and the canyon its self is best explained by the long slow process of erosion by river. I could probably find some detailed studies if you'd like.

What about comets causes problems for you. Tell me and I'll do my best to clear up any misunderstandings you may have.
Also, I've noticed you seem to have a problem common to many Creationists, you conflate geological evolution, astronomy, abiogenisis and biological evolution. Geological evolution is, as the name suggests about the changing of our planet over time and includes stuff like erosion, desertification and plate tectonics. Astronomy is the study of the stars and can include stuff like the big bang and the formation of our solar system.Abiogenisis is the idea that life originated from non-life due to the chemical conditions present on Earth at the time. Biological evolution is what you seem to want to debate and it's all about the adaptation of animals over subsequent generations due to natural selection. Even if one is disproved it doesn't necessarily invalidate the others because they're all separate theories with their own evidence and implications. The fact that they all tend to support each other where they overlap just adds credence to them all.

Second, it is obvious that you have chosen a belief system and grasp at any evidence to support it, blatantly disregarding all other evidence. A google of those papers make them look to be two "classics" that creationists refer to again and again. The youngest is over 10 years old. Where are the more recent Science/Nature papers that confirm the conclusions of these papers? They don't exist.
Here is an acid test for good research: Does it stand the test of time? Is the field explosive in the scientific field 10 years later? Some examples of paradigm shifting fields are stem cells, apoptosis, and RNA catalysis. The papers you cite do not measure up to these standards and so are highly suspect. Good science gets confirmed by other scientists and not by conjecture or preachers who thumpin bibles. Where are the papers confirming the 6500 year old mitochondrial clock or have recent advances shown problems with the previous model? Do the research yourself if you are objective like you think you are--or you can remain blinded by your belief system. But if you wish to remain blinded by your belief system, don't burden others with your belief system like you are doing here.
When uninformed people have opinions on science that smell of belief and bias, my suggestion to them is to go spend five to seven years to get a PhD in a field of natural science. Don't cop-out and pick some religious school where you end up with a thesis full of bible quotes. Find a real state-run university without any allegiance to any religion. Do actual research out in the field (dig bones, sequence DNA, dissect plants, count the strata of geological formations, etc.), synthesize the data and write your thesis on what you have discovered. Don't lie and make up data to support your belief system! Even [insert your favorite religious prophet or diety here] wouldn't do that, right? Integrate the comments of your committee and defend your thesis in front of them. Once you have your PhD from the accredited state-run university without any religious affiliation, come back and examine your belief system from the perspective of a trained scientist. Until then, you are simply fooling yourself, discrediting the members of your faith, and annoying the knowledgeable.
