I'll do this once. If you actually address the points with some scientific counter point then we can continue, though I suspect that babel, name calling, and thread leaving will ensue.
Camlax..... firstly you aint dealt with me before, secondly i read all your posts and their old, the info i will proved you better read it like i read your nonsense. Its all been refuted. but because you threw a lot of red herrings at once, i will do me best to address each one.
Maybe you saw that being read differently in your mind? You might want to copy+paste where these red herrings are and maybe some refutations for them. Because you have yet to post any, which leads me to the conclusion you didn't read a single thing.
As a minor side note, I made that post at 10:24 AM, you addressed it at 11:00 AM. Judging by your posts, I am going to go out on a limb and assume your reading skills/speed is somewhat on par with what you type, also providing (at least to me) evidence you did not read those links. I mean I could be totally wrong though....
The rest has all been refuted, yo obviously did not read the posts sent, instead other poeples comments, which have been going around incircles coz they dont read the posts too. maybe too complex, if only they brains had evolved.
What is this? A bad attempt at an insult? Where has this stuff been refuted? Please make use of quotes and replying directly to them. It goes like this

Sickle cell, one benefit out wieghts the numerous disadvantagesmand you call it evolutionary and beneficial. LOL
Obviously, you have failed somewhere to understand evolution and mutations. Ok Ozi, it goes like this. (This is extremely simplified for you more biologically-minded people, but I think we need to start off here around a freshman high school level).
Lets say for a disease like sickle cell (SCA), you have 2 alleles. "Big A" (A) and "Big S" (S). Being that were diploid (we carry 2 alleles for each gene), We can have a combination of individuals. AA, AS, SS. Lets go through each of them.
AA: would be "normal" red blood cells. They are basically bags of hemoglobins (Hb) and work just fine. However, they (AA individuals) have an extremely high susceptibility to the malaria parasite, Plasmodium
AS: These individuals, have seemingly normal looking red blood cells. Under certain conditions though (like high altitudes) "sickle cells" can be induced. This genotype has increased resistance to the malaria parasite, thus imparting the individual a great benefit (in areas of the world where malaria is endemic).
SS: These individuals have the typical "sickle" cells, which cause all sorts of problems to the individuals, such as capillary bed blockage and decreased Hb capacity.
Ok, So what can we predict about this based on evolutionary theory? Well we could predict that the genotype AS (providing a clear benefit) would be experiencing positive selection, that is to say becoming "fixed" in the population. We could also predict that increase in heterozygous individuals would correlate to an increase in homozygous recessive individuals. So are our predictions correct?
Well first, lets talk quickly on stabilizing selection. We can think of stabilizing selection as being selection against extremes. We can easily visualize this with a graph.
So if we imagine on our graphs, we have our 3 genotypes; AA, AS, SS. Where AA would be on the left end, AS in the center and SS on the right end. This is exactly what is happening in Africa today. Individuals being AA are being selected against for lack of resistance to malaria, individuals being SS are being selected against for lack of blood cell functionality and individuals being selected for (AS) due to "normal" blood cell functionality and resistance to malaria.
So what about this other prediction that we made? "The genotype for SCA should be more frequent in areas of the world where malaria is endemic, due to selection for heterozygotes". Well, one only needs to look at an overlay map to see this is correct as well.


Green is malaria, Blue is population-density for sickle cell anemia
We can also see it in the overlay of heterozygous individuals.

Information theory etc, will be all dealt with coming soon to a thread near you. and well thermodynamics and protiens and dna and rna.
Ill be pinching my ass off in angst for this "information theory argument". Also, if you could find time in your undoubtedly busy schedule to address the links on information theory and thermodynamics I would be grateful. As a physicist, I would love to see your thought provoking arguments on thermodynamics (I am sure the engineers like Harte would love to as well).
well then according to above, when the pressure come, which in this case would be when the sh** hits the fan, and yeh we are all going to die, thats when the mechanisms of variations, mutations , speciation, etc kick in. This is nonsense, then why are those animals struggling to survive, evolving, even at small levels, so show us that evolution is taking place, why not even small differences, or even an attempt by evolution to help them before they die out.
Most of what you typed here makes no sense (at least to someone who reads and writes in english). I think the problem is though, at least what it sounds like to me, is you make an assumption that evolution is guided/end product oriented/knowingly usable by animals. Let me correct you on that, its not you are wrong.
You say"Individuals that have thicker body hair or a thicker layer of fat aren't going to prosper any more than those who do not."
They will in those conditions of the eskimos. So you aknowledge that all mechanisms ar supposed to inmprove the specie and give it an advantage then why and how does the advantage of having sickle cell out weigh the many disadvantages of having it.

Raptor gave you an explanation, you either were not reading it or chose not to read it or didn't understand it. One of these is correctable. Evolution is not guided, if it were the "design" and layout of organisms would be much great, in deed Eskimos would probably have fur. However, in nature (as with life) there is often numerous solutions to a problem. Some may seem less sensical than others, but nature does its work without common sense in mind. Man lost its hair a long time ago. Back in Africa. In fact there have been some really interesting studies done with molecular clocks and divergence of human hair parasites (lice), which actually correspond very accordingly.
Anyway, by time people crossed the Bearing Bridge, people had long since made use of animal skins for warmth. Our expansion out of Africa was rather quick and supplemented with complex tool use and social development (like "clothes"), which really negated having humans with blubber or fur ever evolve.
You say"For this to be a fact you would have to be able to unequivocally prove which proteins were formed and in what conditions. I won't hold my breath waiting."
Well, i this figure has been posted before and i will psot you the whole thing soon with a full explanation on it, and the conditions it was done in. and all the erly earth conditions will be considered along with lab conditions too and guess what we will bring in millers experiment too. hows that sound

Yes you would welcome to statistics 101. One can not pretend to know the odds of an undefinable set. Such pseudomath is moot.
I understand the processes involved in evolution so dont patronise me. The point i made is, then why have'nt any evolutionary mechanism taken place on a micro and macro level thus far with eskimos for example or any other humans in relative isolation bring in to play geographical variations etc.?
I am gonna break for a small disclaimer, As always I recommend formal education on the matter if you are indeed interested. Pop-up community colleges in the US have made higher education (at least some basics) cheap and accessible to everyone. Some of these subjects you are attempting to address are not learned till the 3-4th year in a BS program. I have no doubt you are capable of learning them, but one cannot build a pyramid from the top down (though you will likely find someone around here that believes otherwise).
Secondly, why are there no intermediates or transitional forms or the evolution from on cell to complex organisms, instead you get the cambrian explosion, when all of sudden lots of complex organism are around. how do evolutionist explain that. where are macro changes or the micro, why are they not visible in fossil evidence etc.
Anyway since you dont actually read what i post, i rather not debate with you. we go in circles.

Firstly, this is a lie. It is a lie and misconception that we have no fossils between the Cambrian explosion and the oldest fossilized cells. The problem is, the soft bodies are not conducive to fossilization, Chitin evolved in the Cambrian, which is why we have a plethora of Cambrian fossils. There are plenty of Pre-Cambrian fossils see some; Pre-Cambrain fossils.
The fact that there are many species under pressure for survival, yet we see no evidence of micro or macro evolution. yet you claim this happening, then why are species going extinct and new one s not replacing them.
Repeating lies does not make them true. Had you read the links you would have also read about the apple maggot fly or Culex pipiens and molestus both of which are new species. Species are also going extinct now for non-natural reasons. But, I have no doubt, that these niches will be filled as well (those being ones created by man made extinctions). The past is also rife with niche filling after species extinction, one only needs a little study on the history of life to learn this....
