Is your concept that we should submit to ALL opinions of those who are more expertly educated? Do you, in your life, treat opinions of experts on theoretical controversial areas the same as observed phenomena? So, for example, a Ph.D in economics who advocates socialism is someone you automatically bow to? I think not (based on reading what you've written in other threads).

This issue of what/who is the creator is hugely important to humanity. Nobody is going to lie down for "experts'" views on theoretical areas on the other side of a highly controversial debate. Get real! :detective:

Check out the logic fallacy of "appeal to authority" if you need more reason to hesitate with your idea.

Don't submit to me or anyone else. I'm not an evolutionary biologist, I'm an academic physician and it happens that I have some degree of expertise in the field through research I've done over many years (as in actual research, not armchair reading); but research by its nature is microscopic and evolutionary biology is not my primary professional endeavor.

My postdoctoral research in malaria was chiefly about pathogenesis, but it turns out that in so doing I identified a gene deletion in the majority of field isolates from our collection site. So clearly there was a selective advantage to this novel phenotype. Some colleagues in the same lab were actually looking at global haplotype mapping, and I'd been looking at the same for human red cell polymorphisms (as malaria receptors) -- so it's impossible to escape evolution as one does research in the life sciences, that organisms have evolved is inseparable from what they are today.

Expert opinion is often useful, though, if it turns out that your assumptions about a field are erroneous or incomplete. That turns out to be the case for you -- but it's your life, it's your intellectual appetite, and if you are content with how you've come to understand evolution, then god bless.

It's not paranoia Paul. I have been around the block more than once and I know how the world works. Natural selection is a very simple idea to inject into science so that science can say that they know what caused creation. Dawkins is just being very overt about it. It is a nice, simple story that can be taught at the 7th grade level. After all, science class has to teach something, doesn't it?

Science teaches science. That doesn't make it anti-religion, just because it so happens that religious stories have been contradicted by science. So put things in their place. Teach kids biology at a level appropriate for their education, leave out polemics about atheism and such, and if they choose to pursue a higher education in it they can learn about the areas of controversy too.

Science?? It's a sonnet about science, a wistful poem about the sublime world as revealed by science. But science it's not. It's him seeing a beautiful, elegant, fascinating world into which he cannot fit a god concept. But that's not science.

This is science -- all basic evolutionary biology research, and you'll have to point out where they talk about god.

OK. I believe what Dawkins is saying is much closer to what is being taught in public schools than what you are saying. Natural selection is a very easy concept to teach in primary and secondary curriculum. It doesn't require much from the student or the teacher. We are all natural selected as the fittest. Simple. Easy to teach. Easy to assimilate. A nice response to religion which teaches God created all. When it comes to teaching, simple is better - whether or not it has anything to do with the world around us. Heck, I was still being taught the Rutherford model of the atom when I went to school. Much easier than teaching the Bohr atom.

So when Johnny asks: Did God create the Universe, the Teacher responds, no Johnny, it was natural selection that created all. So the teacher looks smart. The teacher always needs to have an answer.

3) there is no evidence for supernatural forces

We don't know enough about nature to know what is 'super' to it.


What I mean by this, is that there is a presumption in all of this about what actually constitutes 'nature'. If it could be shown that 'mind' or 'consciousness' were a fundamental reality in its own right, then it would not be hard to show that this is implicated in the entire process of evolution. It doesn't need to be concieved as a 'great architect', it can be understood as an inherent organising principle that is seeking to realise itself through the process of evolution. But scientists are generally doggedly resistant to the idea or to any evidence for it, whether it be in the form of Sheldrake's morphic fields or the reality of telepathic communication (which shows that mind exists on a completely different level to matter). Basically, they are always saying 'give me something I can understand and measure', this being a material object or element and the transactions between them. So it is axiomatic in all of this that consciousness is only the by product of a material brain which has somehow spontaneously evolved over the last billion years or so. This is the way science defines reality, as the editor of Nature said about Sheldrake, 'that is magic, not science'.

Well maybe there is a little bit of magic involved in all of it.

Uh no. I define it as change in allele frequencies as a function of time. Leave all interpretation, like whether it's adaptive or not, out of the conversation.

I didn't say he was my hero -- I just said I liked his books and I thought he was a better representative of evolutionary science than Dawkins.

I don't really acknowledge "adaptive process" as a mechanism of evolution, so enough of this repetitive crap already. All, 100% of animals (or at least chordates), begin embryogenesis in highly similar ways. They all form similar early embryos with similar early germ layers. All gut-derived organs including the lungs are produced by modification of endoderm. The central nervous system is a modification of ectoderm. So at least at the level of early embryogenesis, the same organ systems exist in animals -- they're all just highly modified once development is complete. And thus the way an apparently new organ system comes into being is by modification of early developmental gene regulation -- and this can be studied fairly easily with gene knockouts, with transgenic embryos, and in humans who have a developmental defect.

But you told me already that you already knew all this.
Comparative Embryology - Medpedia

You're right, I'm guilty of elevating my case in response. Can you make the same admission?

The way you phrase this inherently evinces assumptions, such as the prospect that something did the creating, or that a whole organism somehow just came into being (as opposed to developing out of constituents). There are a LOT of incomplete organisms in this world -- mycoplasma, ureaplasma, and the entirety of viruses, for instance.

If you extend your complaint beyond one author, and if you systematically look at "representations to the public", and if you learn the meaning of the word "theory", and if you develop a credible knowledge base such that you KNOW the areas of controversy, then your argument may have a bit more meat on its bones.

It's not proven -- but it's parsimony. Indulge the following reasonable assumptions:

1) life didn't always exist
2) at some point or after some interval it did exist
3) there is no evidence for supernatural forces
4) living things have the same chemical constituents as nonliving things
5) living things are fully susceptible to natural phenomena

Based on the above, it would be a work of fantasy to say that life came into being in any way other than by natural processes. So why should I even care about your "I'll never buy that"?


Have it your way.

No, the (wise) teacher says that this is a matter of personal belief that not all other students in the class would share, that explanations about the universe and its origins come not only from science but from many traditions, and the subject of the class is the scientific understanding.

Nature may not be understood, but it is observable and predictable. The hand of god is not. By definition something supernatural would be something that openly violates nature. And I restate that there is no evidence for such a phenomenon. When you raise the dead or part the waters by raising your staff, I might reevaluate my position.

I live in the midwest, and I know that many of the schools around here, through high school, will never even mention evolution or the name of Darwin. I took biology in high school around a decade ago, and there was no mention of it.

I would only imagine that it is like this, if not much worse, the farther south you get, considering many of their anti-evolution education laws that have existed even until recent times.

Quote:
"The National Center for Science Education, in Oakland, CA, where I work, has tracked hundreds of attacks on evolution education in 48 states in the last five years. In the last two years alone, 18 bills in 10 states have targeted the teaching of evolution. These bills, like the flawed science standards approved by the Texas Board of Education in March, don't ban evolution outright. But they do authorize teachers to omit evolution or include creationism at their whim."

It's the case for me???

Wow, even after all the arrogant BS I've run into in my debating career, I am still shocked at your tactic. It's an unbelievable abuse of the trust you have been given here to pretend you have the "truth" on a such highly controversial subject. What kind of victory is it to win a debate by using your position to malign my views and education?

As I said, have it your way.

@richrf,
You clearly did not read my post. I did not say I was an expert, in fact I clearly state the contrary. My point is that I have experience and expertise at an academic level in this field and that some of your positions are contrary to an evidence-based understanding of this science. And this subject is a lot less controversial than you think.

I don't malign your views or your education. I don't malign anything. The errors in your understanding are yours to recognize and supplement if you so choose. That point is not a matter of debate, because it's true for all of us.

Further, I do not claim as you do to have had a "debating career". But if I were to characterize any tactic as "arrogant BS", I might start with the feigned offense, the feigned indignation, and the twisted misrepresentations that constituted your last post.

Finally, as for the "unbelievable abuse of the trust you have been given here", you can compare and contrast our respective willingness to admit our lack of knowledge, our willingness to bridge gaps, and our willingness to take one another's posts at face value rather than distorting them into some rhetorical bludgeon. I think I've done a pretty good job in this thread modeling the way a forum staff member should behave when participating in a heated debate. But if you don't agree, I'd be happy to ask the rest of the team to join in and point out the error of my ways.

Okay, I was merely unpleasantly surprised, I didn't think you'd resort to that. But I have had a debating career, which is why I see that you are in a position here to continue to abuse all who disagree too intelligently, so I'll leave you to your fun.

It was certainly very much part of my curriculum in New York and apparently natural selection is very much alive in Dallas, TX though creationists are trying to modify the curriculum.

In every state curriculum that I have googled so far, natural selection has been part of the standard curriculum. (I posted this previously).

It may technically be in the curriculum of many states, but that doesn't mean they're teaching it in all the schools. Much of it depends on the community.

The first time I had any real formal instruction on evolution was when I got to my college "intro to evolution" class. Right away, we got into a discussion about everyone's background on evolution, and nearly all of these students, who came from similar high schools as mine, scattered around the rural midwest, had never been exposed to it in the classroom.

I am sure that different teachers choose to teach what they want to teach, but it is part of the College Board SAT tests for biology, so if it not taught then the schools are putting their students in an awkward position:

@richrf,
I wasn't going to comment at all in this thread but not because I don't have anything to say on the topic. I have plenty to say but it just seems like the argument will never be settled ever. So I have some interesting ways to look at the subject matter.

Why couldn't a god create the universe in such a way that the known laws of the universe were set in place so things would work themselves out naturally? Why couldn't this being create the underline rules of biology thus enforcing the notion that evolution was the intended process? This seems perfectly logical to me yet I find it incredibly hilarious that a majority of religious people neglect this concept. The worse part about it, is I am defending something which I do not believe in.

There is plenty of evidence that evolution is happening.
There is plenty of evidence that natural selection is at work.

Anyone who argues against the evidence is being intellectually dishonest. I could say it a nicer way. Why not give your god some credit that he intended things to work in a natural way? But like I said, I don't believe in gods.

I am always amazed that the same people who cannot figure out simple things in life, for example, is it going to rain today?, are so quick to give pat answers on what happened millions of years ago. Talk about intellectual honesty. Let's just call it a Hail Mary.

But Sheldrake's morphic field is not evidence, it's an idea.

In order for Sheldrake to turn his hypothesis into something that can be described as the sort of evidence required by science he is going to have to propose some ways of examining the idea of morphic fields, and design some tests or logical exercises that demonstrate that it might not work, or apply in all circustances.

One of my favourite authors, Alan Moore, is very fond of Shedrake's idea, and posits that it might explain why numerous people came up with things like lightbulbs, or stream trains, or telephones. He reckons (tentatively) that Sheldrake's idea might make it sensical to think of the early 19th century as "steam train time" - that trains would have come about without the ingenuity of any particular person.

However, I have to question the logic of this - obviously a candidate for an opposing PoV is that the ingrediants for steam trains existed and it was just up to someone to bake the cake. Also, after all, other inventions do seem to have come out of nowhere - why would this be so if the notion of Morphic Fields applied?

As an example - in 2002 or so some friends and I noticed that a number of unsigned bands were struggling to market themselves in london. We had interests in multimedia, and discussed setting up a service by which these bands could - through us - generate their own simple websites and music videos.

The project failed due to a lack of enthusiasm and expertise on our part - but a little later when YouTube and MySpace appeared I couldn't help thinking "oi!"

Now, I reckon the niche was just there to be exploited - the net was there already, so were videos, so were bands wanting extra promotion - I don't give the "it was MySpace time" idea much credit - though I do remain generally impressed by Moore.

A rough analogy could be drawn between ecological niches becoming available that suit certain adaptations (bearing in mind the problems with that word) that arise via natural selection leading to similar morphologies in different types of organism.

So rather than it not being "wing time" until insects developed them - which therefore allowed birds and reptiles and mammals to take the same route - it could just be that wings are great adaptations for things which live in niches involving lots of space to (potentially) fly about in.

The idea that organisms have the potential to exploit fresh niches through morphological change is confirmed (to my satisfaction) through experiment.

The idea that once a particular organism develops a particular adaptation (bearing the problem with the word in mind) other organisms somehow access it through a shared field has yet to be (indeed, some experiements seem to point to this not being a case at all).

So whilst the editor of Nature was being a bit rude and hubristic, he wasn't wrong to stress that Morphic Fields aren't science (at time of writing).
