Yup, cells are complicated. Perhaps for point of discussion of evolution, you could remind all what the central dogma of biology is which is the core starting point of evolutionary theory.

From Wikipedia:

Quote
Use of the term "dogma"

In his autobiography, What Mad Pursuit, Crick wrote about his choice of the word dogma and some of the problems it caused him:

    I called this idea the central dogma, for two reasons, I suspect. I had already used the obvious word hypothesis in the sequence hypothesis, and in addition I wanted to suggest that this new assumption was more central and more powerful. ... As it turned out, the use of the word dogma caused almost more trouble than it was worth.... Many years later Jacques Monod pointed out to me that I did not appear to understand the correct use of the word dogma, which is a belief that cannot be doubted. I did apprehend this in a vague sort of way but since I thought that all religious beliefs were without foundation, I used the word the way I myself thought about it, not as most of the world does, and simply applied it to a grand hypothesis that, however plausible, had little direct experimental support.

Similarly, Horace Freeland Judson records in The Eighth Day of Creation:[6]

    "My mind was, that a dogma was an idea for which there was no reasonable evidence. You see?!" And Crick gave a roar of delight. "I just didn't know what dogma meant. And I could just as well have called it the 'Central Hypothesis,' or — you know. Which is what I meant to say. Dogma was just a catch phrase."

But, I have a problem with stating that this is the starting point of evolutionary theory. For more about the core theory of evolution, the Wikipedia entry is a good starting point.

http://en.wikipedia.org/wiki/Evolutionary_theory

And in reference to going back from the eukaryotic cell, Peter you posted this:
Quote
Great start for building our cell, but we need to have complete eukaryotic cell to begin our discussion on evolution as defined as a change in gene frequencies over time.

So, we need someone to build some mitochondria, ribosomes, nucleosomes, our lipid cell membrane, our Golgi apparatus and the rest of the essentials of a single celled eukaryote that will be able to evolve.  So, let's get the entire cell together to make sure it has all of the correct parts to survive.

Any volunteers to start building our cell?

True, the video links you posted are not from the creationist viewpoint, but I maintain that you are throwing up a smoke screen for these reasons:

1. Cells ARE complex. You intimate that there is much not known about how they developed. Possibly true, but there is also much known.
2. Even those things that may still be unknown are in no way a proof that they could not have evolved.
3. The discussion of evolution is completely different than the discussion of the origins of life. Saying that "someone" had to build the cells that are under discussion has nothing to do with evolution and everything to do with creationism.

Please pardon my ignorance but are there still people in America who doubt any theory of evolution?  I understand the debate on theories (no, I don't understand them but rather I understand why do you them) but not, in this day and age, whether?  Can someone recommend a primer for me?  I hate conversations that I can't understand.

Thanks for the links, Monrien.

# 20 is already done. Will follow up on the others.

BTW, my husband was already reading the Coyne book that you posted the review on. He says it is a good one!

And Peter, I wish you wouldn't assume that I have not watched the videos you linked to.

Eucaryotic Cells Contain Several Distinctive Organelle

Eucaryotic cells, by definition and in contrast to procaryotic cells, have a nucleus (caryon in Greek), which contains most of the cell's DNA, enclosed by a double layer of membrane (Figure 1-18). The DNA is thereby kept in a compartment separate from the rest of the contents of the cell, the cytoplasm, where most of the cell's metabolic reactions occur. In the cytoplasm, moreover, many distinctive organelles can be recognized. Prominent among these are two types of small bodies, the chloroplasts and mitochondria (Figures 1-19 and 1-20). Each of these is enclosed in its own double layer of membrane, which is chemically different from the membranes surrounding the nucleus. Mitochondria are an almost universal feature of eucaryotic cells, whereas chloroplasts are found only in those eucaryotic cells that are capable of photosynthesis - that is, in plants but not in animals or fungi. Both organelles almost certainly have a symbiotic origin.

Perhaps the most important micro motor of life is ATP synthase.  It is one of the smallest machines known with near 100% efficiency.  Cyanide works against this machine and causes death within 30 seconds.

Here is an excellent presentation on this remarkable machine in eukaryotic cells.

The mitochondria are the energy unit in eukaryotic cells.  This is where ATP synthase works nonstop at a rapid rate of 10,000 rpm.

However, ATP synthase is only part of the energy producing chain and how oxygen is used in the cell.  If this electron chain is disrupted, life in the cell will cease.  All elements of this system is specified in the genetic information contained in the cell's nucleus.

Here's # 20

Dear Monrein,

I went through the video a couple of times.  He talks about his research making vesicles that self assemble.  He speaks of soap bubbles that self assemble which is all about surface tension.  It would be interesting to get ahold of some of his papers on his specific research, but the example that he used for our understanding is accomplished by simple surface tension factors.  It does not involve information, it is a physical property of the soap solution.  Without reading his papers, I assume that his direct experimentation follows all of the tenants of the experimental method.

http://www.sciencebuddies.org/mentoring/project_scientific_method.shtml

He then goes to the ATP synthase molecule and doesn't give an real sense of the amazing complexity of this molecule.  It is actually not one molecule as he kept stating but at least 31 separate proteins all working together to make a rotary engine operating at 10,000 rpm and so essential to life that it will cease immediately if these machines shut down.

He then went and implied that other people in the field of molecular biology are performing experiments on ATP synthase and showing how it evolved from less complex to more complex.  Here is where the bait and switch occurred in his statement.   They have actually performed no experiments at all according to the scientific method.  They have instead constructed complex family trees of ATP synthase called that we refer to as phyolgeny.  Quite interesting, but the difficulty is that they are constructing phyologenetic family trees based on many components of the cell such as histones, cytochrome c, ATP synthase and many other components.  It all sounds good doesn't it.

The problem is, the individual component family trees to not show the same patterns of alleged similarities when matched together.  He takes his experimentation on the physical properties of different compounds completely devoid of intelligent information and then implies in my opinion falsely that we have the same level of data for the evolution of ATP synthase.  Not true at all.

Take a look at the write up in Wikipedia on the alleged evolution of ATP synthase:

Evolution of ATP synthase

The evolution of ATP synthase is thought to be an example of modular evolution, where two subunits with their own functions have become associated and gained new functionality.[5][6] This coupling must have occurred early in the evolution of life as evidenced by essentially the same structure and processes of ATP synthase enzymes conserved in all kingdoms of life.[5] The F-ATP synthase shows large amounts of similarity both functionally and mechanically to the V-ATPase.[7] However whilst the F-ATP synthase generates ATP by utilising a proton gradient the V-ATPase is responsible for generating a proton gradient at the expense of ATP, generating pH values as low as 1. The F1 particle also shows significant similarity to hexameric DNA helicases and the FO particle shows some similarity to H+ powered flagellar motor complexes.[7] The α3β3 hexamer of the F1 particle shows significant structural similarity to hexameric DNA helicases; both form a ring with 3 fold rotational symmetry with a central pore. Both also have roles dependent on the relative rotation of a macromolecule within the pore; the DNA helicases use the helical shape of DNA to drive their motion along the DNA molecule and to detect supercoiling whilst the α3β3 hexamer uses the conformational changes due rotation of the γ subunit to drive an enzymatic reaction.[8]

The H+ motor of the FO particle shows great functional similarity to the H+ motors seen in flagellar motors.[7] Both feature a ring of many small alpha helical proteins which rotate relative to nearby stationary proteins using a H+ potential gradient as an energy source. This is, however, a fairly tenuous link - the overall structure of flagellar motors is far more complex than the FO particle and the ring of rotating proteins is far larger, with around 30 compared to the 10, 11 or 14 known in the FO complex.

The modular evolution theory for the origin of ATP synthase suggests that two subunits with independent function, a DNA helicase with ATPase activity and a H+ motor, were able to bind, and the rotation of the motor drive the ATPase activity of the helicase in reverse.[5][8] This would then evolve to become more efficient, and eventually develop into the complex ATP synthases seen today. Alternatively the DNA helicase/H+ motor complex may have had H+ pump activity, the ATPase activity of the helicase driving the H+ motor in reverse.[5] This could later evolve to carry out the reverse reaction and act as an ATP synthase.[6]

This is not science, it is simply hypothesis and speculation that is not subject to any experiment.  The video you gave is a prime example of bait and switch that we see throughout the evolution/creation debate.  Experiments with soap bubbles based on surface tension and naturally occurring surfactants is not at all analogous to self assembling a micro machine giving all life the energy of life that is based on complex information that is preserved essentially unchanged between all cellular life forms.  On the contrary, ATP synthase remains one of the most amazing evidences of a Creator as do all of the micro machines with in the cell.

So, great example of bait and switch but absolutely no evidence of evolution of this critical element of life.

Dear Peter
I wish you all the best in your quest to disprove the rather considerable body of knowledge that has accumulated to support the theory of evolution.  In the interest of fair disclosure, let me be the first to point out that I am not a biologist, nor am I a chemist, a physicist, a geologist or an astronomist.  What I do think I know is that the preponderance of those folks who have spent their lives pursuing scientific discoveries , including a fair number of christians, accept that this body of knowledge is important although as yet incomplete.  I also find it curious that while science sets out to continuously overthrow old ideas in favour of new ones, this is after all how young scientists make a name for themselves, the theory of evolution has gained more traction, not less, in the past 150 years.  This growth in knowledge and acceptance is not based on faith nor is it founded on dogma although I think I understand that in your view it is.
I wish you all the best Peter and I would respectfully suggest that you direct your energy and passion about the errors and fallacies of evolutionary science to those men and women, the practicing scientists, who would be in better positions to debate the details with you.  Could you for example refute the points that you refute here and present them to scientific journals for publication.   I confess that I'm gobsmacked by the young earth creationist view of the world and will continue to take my chances with the scientific method as it seems to me more likely to result in a fuller understanding of our physical selves and of our environment.

Can we get back to the discussion of evolution instead of how a cell works?

I thought we'd agreed on a starting point of a single eukaryotic cell. How this cell arrived should be irrelevant to the discussion.

My view is that it evolved from simpler life forms; I indicated the major changes that would have to evolve to result in the cell — more changes than needed to progress from a single cell to man. Moreover the time for evolution to the eukaryote is over four times as long as from the first eukaryote to man.

On the other hand, Hemodoc would have it that the eukaryote was created, because it is so complex.

Can we keep the arguments to the development from the first eukaryote to man? There's enough there to give Hemodoc a bit of a headache to explain. The most significant difference between evolution and creation is that evolution does not have an objective whereas creation implies that the creator does. Moreover, the Bible makes man the epitome of creation, so we would expect all living things between eukaryotes and man to support the creation of man.

Viruses need explanation. Viruses have no reproduction mechanism of their own; they hijack that of other cells. Other life forms have mechanisms to kill off viruses once they have been infected (although they do not always work). So why did the creator create viruses only to have to create mechanisms to kill them off in other life forms?

Hemodoc maintains that complexity is indicative of a creator. I take the opposite view: complexity is indicative of evolution. Look at the skeleton of birds and mammals. All are nearly the same but pulled and stretched to some extent. They have the same set of bones. Bird or beast, they are basically the same but the complexity allows the differences. A designer on the other hand creates a design that is optimized to do what's intended. A designer doesn't take a railway engine and modify it to make it into an airplane. No, he designs an airplane from the start to fly.

Well, there's two issues that need explanation; I'm sure others can think of more.

Dear Peter
I wish you all the best in your quest to disprove the rather considerable body of knowledge that has accumulated to support the theory of evolution.  In the interest of fair disclosure, let me be the first to point out that I am not a biologist, nor am I a chemist, a physicist, a geologist or an astronomist.  What I do think I know is that the preponderance of those folks who have spent their lives pursuing scientific discoveries , including a fair number of christians, accept that this body of knowledge is important although as yet incomplete.  I also find it curious that while science sets out to continuously overthrow old ideas in favour of new ones, this is after all how young scientists make a name for themselves, the theory of evolution has gained more traction, not less, in the past 150 years.  This growth in knowledge and acceptance is not based on faith nor is it founded on dogma although I think I understand that in your view it is.
I wish you all the best Peter and I would respectfully suggest that you direct your energy and passion about the errors and fallacies of evolutionary science to those men and women, the practicing scientists, who would be in better positions to debate the details with you.  Could you for example refute the points that you refute here and present them to scientific journals for publication.   I confess that I'm gobsmacked by the young earth creationist view of the world and will continue to take my chances with the scientific method as it seems to me more likely to result in a fuller understanding of our physical selves and of our environment.

Dear Monrein,

Thank you for a cordial disagreement.  That is a breath of fresh air.  I am not trying to disprove evolution, only to show it for what it really is and the limitations of the conclusions that can be drawn from the evidence available.  I as well place a fair amount of trust in the scientific method which is the best that we have ,but it is not infallible.  The point that I made in my post above is that the evolution studies do not follow the scientific method which is a hypothesis followed by experimentation.  What the video described was experimentation on the physical properties of different organic and non organic chemical associations leading to "bubble" formation which is dependent not on coded information, but on physical properties of the chemicals involved.  He then used that as an analogy to imply that we have the same type of studies with evolution "looking back into the past" to establish family trees through the study of the ATP synthase molecule, which is not actually one molecule but dozens of molecules that form a functional rotary engine operating at 10,000 rpm.

In such, it is observational with correlation based on the philosophy of evolution.  I can look at the same data and draw my own conclusions based on my philosophy of creation.  There is no experimentation that can lead to a cause and effect, yet the evolutionary scientists do draw cause and effect.  In such, these studies do not follow the scientific method since it is not subjected to a scientific trial.  I agree, the scientific method is a good, but not perfect manner in which to draw cause and effect, but I am hard placed to look at any studies where complex coded information occurs naturalistically from chemicals leading to self assembly of a near 100% efficient, rotary engine operating at 10,000 rmp.  Science has never shown anything of this sort.  Science has never shown life to come from non life, this was settled over a 150 years ago.

So, I am not setting out to disprove evolution, simply to show what the limits of the conclusions of the data show or don't show.  You don't need to publish to be able to analyze something in that manner.

Lastly, it is interesting to look at your comment in one more manner.  You are in essence stating that you place your trust in the scientific method, or simply put have faith in the evidence of evolution from all of the science.  I hope you can look at what the scientific method is and isn't.  Looking back into the past does not allow experimentation in the present.  It is two different methods of gathering data and evidence.   One is experimental, one is observational with out the ability to establish cause and effect.  That is my only goal.  In reality, I have faith in the God of the Bible for various data and evidence, and you have faith in the data of evolution which is not actually subject to experimentation.  Belief in evolution becomes a matter of faith just as is my belief in God.

Dear Stoday, this site is for debating our points of view on this issue. I postulate that these mechanisms of cell function are the central issue of the creation/evolution debate, so you may not agree with my view, it is still my right to speak my view and the evidence for that view.  That is what a debate is after all.  So, my educational posts on the basic function and components of a eukaryotic cell is absolutely relevant to the discussion at hand.  It is in fact the basic essence of this entire debate, if in fact you folks really want to look at the real issues at hand. 

 It is a quite simple fact that most do not have a science background and understanding of what a eukaryotic cell involves. You are quite mistaken that I have talked about how these elements were formed, since no one at all has any clue to how they were formed by naturalistic processes.  All we have is speculative propositions, or hypotheses on how it COULD have occurred, but not experimental trials of those hypotheses that I am aware. Observational data is hypothesis creating, it is not able to show cause and effect.   If you know of any, I would be quite interested to reading about them.  Remember observations are not the same as experiments.   If we do not have a basic  understanding of what is inside of eukaryotic cells and what constitutes life in a single celled eukaryotic organism, there is absolutely no room for understanding the basic principles of evolution which are based on the central dogma of biology which you have yet to explain although I did invite you and others to do that.  To understand the central dogma of biology, you need to understand the support system of a "simple" cell.  The elements of the central dogma of biology are all carried out by complex molecular machines.  It is essential to understanding the coming elements of evolution to grasp this most amazing concept.  Take a look at another animation of this central fact.  You will see all steps of DNA copying and functional use.

http://www.youtube.com/watch?v=GkdRdik73kU

How shall we gain an understanding of what the theory of evolution claims for complex higher order organisms if there is no foundation of the "simple" unicellular organism.  In fact, go and take a course on evolution and you will study all of these issues that I have laid out with these incredible animations that we have available today.  I didn't have the benefit of these animations when I took my studies on these issues and simply looking at a two to 5 minute animation gives the information that I had to accrue through many days and hours of studying.

On the other hand, yes of course, I do not believe that these things occurred by chance alone, but I have chosen instead of postulating that, I will simply put forth for all to see the complexity for themselves.  If you choose to believe that these things self assembled after seeing how simply incredible that they are, go for it.  But to state that I shouldn't describe and educate on what is the basic components of a cell is simply foolish since it is the central aspect of the biology of evolution.  What else are we going to talk about but cell systems, organelles, functions and the aquisician of more complex cellular and organismal systems and features.  I will not assume that all have the same understanding of these systems that I do after literally decades of study.  The availability of incredible animations makes it quite possible for a complete lay person with no science background to easily understand the complex issues involved in this discussion on evolution without any undo time and study.

In fact, I have put forth all of the basic structures that I had planned to do for the purposes of common understanding for all to be able to participate in this discussion on evolution.  In fact, it will not be necessary for me to mention special creation at for me to put across my point of view of the incredible evidence of an intelligent creator in any of my discussions.  The evidence of the biology and increasing complexity of the systems and functions will be my only voice in this discussion that I will center completely on the topic of evolution.  So, let the games begin, Stoday, go evolve all you want, but please tell us facts, not conjecture and speculation if you can on where we go from here.   The only caveat is that the videos that I selected should give anyone interested in this study a basic understanding and I would recommend all to look at each of them.

If anyone has any questions on the technical aspects of the eukaryotic cell, please do not hesitate to ask and I will do my best to find easy to understand sources that will help direct your learning of this.  So, please, go evolve Stoday and please do it through facts and data and not philosophical speculation on how it "may" have occurred.  Just scientific facts that we have had subjected to the complete scientific method as Monrein has asked.

Oh, I see. I think.

You didn't want to start with the Eukaryote after all. You want to start with the RNA world from which prokaryotes, mitochondria, chloroplasts etc evolved eventually to form the first eukaryotes. That is, the eukaryote is the end of the discussion about evolution, not the start. Am I right this time?

I take it you don't want to explain the existance of viruses eh?

I have already put down the basics of a eukaryotic cell to give the other people on this thread that read but do not post a background to the discussion.  Please, give us your best evidence of evolution from the unicellular, eukaryotic state to the next stage in the Precambrian era.

Here is a creation overview of the issue of evolution up to the point of a eukaryotic cell.  It has an excellent overview of what the eukaryotic cell entails, and problems with some of the theories of evolution of the eukaryotic cell based on known observations.  It also has a short comment on viruses as well.

In addition to the structure of eukaryotic cells, you will need to understand the concept of the geologic column.  Eukaryotes are believed to have developed in the precambrian era.

Here is a peer reviewed science paper showing that the proposed transition from prokaryote to eukaryote is more problematic than thought before:

Eukaryotic evolution, changes and challenges

T. Martin Embley1 & William Martin2

Top of pageAbstract
The idea that some eukaryotes primitively lacked mitochondria and were true intermediates in the prokaryote-to-eukaryote transition was an exciting prospect. It spawned major advances in understanding anaerobic and parasitic eukaryotes and those with previously overlooked mitochondria. But the evolutionary gap between prokaryotes and eukaryotes is now deeper, and the nature of the host that acquired the mitochondrion more obscure, than ever before.
