here are two great papers explaining why evolution cannot occur because the mutation rates are too high. they both come to the same conclusion.
The high deleterious mutation rate in humans presents a paradox. If mutations interact multiplicatively, the genetic load associated with such a high U [detrimental mutation rate] would be intolerable in species with a low rate of reproduction [like humans and apes etc.] . . . The reduction in fitness (i.e., the genetic load) due to deleterious mutations with multiplicative effects is given by 1 - e -U (Kimura and Moruyama 1966). For U = 3, the average fitness is reduced to 0.05, or put differently, each female would need to produce 40 offspring for 2 to survive and maintain the population at constant size.
www.detectingdesign.com...
Widely recognized geneticist James Crow in an article in the same Nature issue agrees that the deleterious rate is more likely twice the rate cited by Eyre-Walker and Keightley8. So if we use Crow's revised rate of U=3, we get: B = 2e^3 = 40 births before we get one offspring that escapes a new defect!
evolutionfairytale.com...
it's over for evolution. human females do not produce 40 children (and 39 would have to die off). there is no way around that.
Evidence continues to mount contradicting the evolutionist's claim that man and ape share a common ancestry.
Over the last 20 years, studies have shown that the human mutation rate is inexplicably too high1,2. A recent study published in Nature has solidified this3.
These rates are simply too high for man to have evolved from anything, and if true would show that man must in fact be regressing (a position very consistent with a recent creation of man). Most evolutionists ignore this problem, and those who do attempt to address it leave us with just-so stories void of any supporting evidence.
Let's first consider the recent Eyre-Walker & Keightley article in Nature magazine3. By comparing human and chimp differences in protein-coding DNA, they arrived at a deleterious (harmful) mutation rate for humans of U=1.6 per individual per generation. They acknowledge that this seems too high, but quickly invoke something called "synergistic epistasis" as a just-so explanation (I'll address this later).
What is not adequately conveyed to the reader is just how bad this problem is for evolution. It is related to the renowned geneticist J.B.S. Haldane's reproductive cost problem that Walter Remine so eloquently elucidated in "The Biotic Message"4.
What we will determine is how many offspring are needed to produce one that does not receive a new harmful mutation during the reproduction process. This is important since evolution requires "beneficial" mutations to build up such that new features and organs can arise (I say "beneficial" loosely, since there are no known examples where a mutation added information to the genome, though there are some that under certain circumstances can provide a temporary or superficial advantage to a species5). If over time harmful mutations outpace "beneficial" ones to fixation, evolution from molecules-to-man surely cannot occur. This would be like expecting to get rich despite consistently spending more money than you make
So, to determine the reproductive impact, let
p = probability an individual's genome does not receive a new defect this generation
A female is required to produce two offspring, one to replace herself and her mate. So, she needs to produce at least 2/p to pay this cost and maintain the population. Let B represent the birth threshold:
B = 2/p
The probability p of an offspring escaping error-free is given by e^-U6. Therefore, making the substitution,
B = 2e^U. For U=1.6, B = 9.9 births per female!
Source #3 is a dead link. Alright I've read the abstracts of the 2 cited experiments, and yes it APPEARS to be higher than EXPECTED.
Now when you look at this statement, it has absolutely nothing to do with the previous one. How are the rates too high to "have evolved from anything?"
Again, the source is a dead link. Is there another source where I can find that U=1.6 assessment? If it's accurate and indeed a 1.6% chance per individual, then where does the 1/40 come from? A 1.6% chance of harmful mutation in a individual is low.
This is "invoked"? Can you show me conclusive data that shows synergistic epistasis is wrong?
Source #4: A christian philosophy book written by Walter Remine, a guy who's got a masters degree in electric engineering (not physics, genetics, chemistry, or anything that has to do with evolution).
If p = the probability of a individual not receiving a defect, then p should equal 98.4%, since U = 1.6 according to the unsourced claim above.
For B: This doesn't make a whole lot of sense. Women produce various amounts of offspring. The number isn't always 2, and our population is growing, so saying that 2 is average to even out the population doesn't necessarily reflect what is actually happening in the real world.
The math does not add up, and isn't accurate by a longshot.

Yes "tons of evidence", "mountains of evidence". Yeah I liked when Firepac said this....
"As I have said before, natural selection has already been demonstrated countless times in other experiments thus does not need to be demonstrated in this experiment."
So as others have posted this is NOT natural selection.
This is ARTIFICIAL selection or breeding.
Ok.
So the OP should read:
"Yeast Clumps Which Appear to be Multicellular, Bred From Single Cell Organism"
Was that so hard?
I have a new theory.
The pyramids were not created by the Egyptians.
They formed naturally.
Yes, I know that according to some of the stories and hieroglyphics the "ancient Egyptians" created the pyramids.
This of course is nonsense.
As proof I am going to conduct an experiment in which we create a pyramid (by replicating early conditions using tools and laborers in a quarry) in order to demonstrate that it formed naturally and was not "created" by any supposed intelligent Egyptians.
Yes, using manual labor is a perfectly acceptable way to demonstrate how these pyramids formed on their own, without any labor.
Naturally.
With no Egyptians..............
So are you trying to say that artificial selection isn't a mechanism for evolution?
Natural selection does not have any foresight.
When selection is spoken of as a force, it often seems that it is has a mind of its own; or as if it was nature personified. This most often occurs when biologists are waxing poetic about selection. This has no place in scientific discussions of evolution. Selection is not a guided or cognizant entity; it is simply an effect.
biologists often anthropomorphize. This is unfortunate because it often makes evolutionary arguments sound silly.
Also, the word fit is often confused with physically fit. Fitness, in an evolutionary sense, is the average reproductive output of a class of genetic variants in a gene pool. Fit does not necessarily mean biggest, fastest or strongest.
Do you seriously want to get embarassed again? And about the Pyramid thing....there's actually physical PROOF that the Egyptian Pyramids were created. There's ZERO PROOF that life was created. Can you spot the difference?

it didn't happen spontaneously, or by accident.
this doesn't confirm evolution, it confirms that a power greater than that of the creature is required for it's creation.
i call that power God.

The science department at Berkeley says it.
Mechanisms the Process of Evolution
These common vegetables were cultivated from forms of wild mustard. This is evolution through artificial selection.
Artificial selection is an artificial mechanism by which evolution can occur.

Under the heading, "Common Misconceptions about Selection" it states

Note that it does not talk Natural Selection but Selection in general.
According to Evolutionary Theory, Selection is not a guided or cognizant entity.
It further stated that

So how can the experiment in this thread have a leg to stand on in regards to "fitness" of the yeast cells when it is breeding them?

There is zero evidence that life came from non life via abiogenesis. But you and I both know that "EVOLUTIONARY THEORY HAS NOTHING TO DO WITH THE ORIGIN OF LIFE"

Barc's has completely demolished your creationist propaganda source. And again, NO, in MY thread, I will NOT tolerate to nonsense such as "my evidence is a site whose url includes "fairy + tale + evolution" I will not go down to your level debate wise. And, again, I will say that "Barc" has completely demolished your propaganda.

Wow. You had to resort to personal insults in an pitiful attempt to justify your position. I explained to you I couldn't find the source of the U claim, and yet you insult my intelligence based on not knowing exactly what the U value meant. I read "probability" as based on that website you sourced. Sorry, I might respond later, but I'm feeling a little insulted right now, even though almost everything you said was wrong.
The high deleterious mutation rate in humans presents a paradox. If mutations interact multiplicatively, the genetic load associated with such a high U would be intolerable in species with a low rate of reproduction
While extreme truncation selection seems unrealistic, the results presented here indicate that some form of positive epistasis among deleterious mutations is likely.
It's still artificial and controlled by an intelligence, humans. Or would you say that plastics are a natural occurrence, because it happens with natural chemicals but under artificial heat and pressure? It was consciously made to do that, whether you like it or not.

"Artificial pressure" just means pressure either higher or lower than the average pressure at current atmospheric conditions. A lot of you are getting thrown off by semantics.
In nature, there are ALL KINDS of bizarre environments where the temperature is wildly different, pressure is wildly diferent, exposure to light is different, etc. What if in nature, these yeast cells were under 1000 feet of water? That's totally natural pressure, but far greater than you'd find in a laboratory - to simulate that, you would need to create "artificial" pressure. The "artificial" environment is found ALL over nature - but to study it under laboratory conditions they have to use methods like this.
Actually the science department at Berkeley says that artifical selection IS a mechanism for evolution.
Natural selection is the driving force of evolution. The environment selects the winners and losers. In artificial selection we are the shapers of other living things.
Natural selection is the mechanism of evolution, the process in nature by which only the organisms that are best adapted to their environment tend to survive and transmit their genetic characteristics to the next generation. Individuals less well adapted to their environment tend to be eliminated, where environment represents the combined biological and physical influences.
It contrasts to natural selection in that it is both intentional and guided
So are you suggesting that god used selective breeding to create all the diversity of life?

Now answer me this, what kind of lab experiment would you accept as evidence for evolution since all lab experiments are artifical?

It doesn't really matter. The formula is still bunk and everything I brought up about the BS website was true, other than the fact that I misinterpreted an unsourced claim of U. Now that you've provided that I'll go back and show you exactly where else the formula is faulty. I never claimed I was educated in genetic mutations or that I was a scientist who studied it. Chances are you aren't either, so don't insult my intelligence when your best claim is a website called evolutionfairytale.com that sources experiments and draws ridiculous conclusions from them that aren't cited in the original experiments and don't even come close to explaining how we "couldn't have possibly evolved". 1/40 mutation rate suggests we couldn't have possibly been created by anything intelligent. It's got nothing to do with evolution.

The estimated genomic deleterious mutation rate, U, is thus ∼3 (U = 175 x 0.017), with a minimum value of 1.5 (U = 91 x 0.017) and a maximum value of 4 (U = 238 x 0.017), based on differences in divergence time, generation length, and ancestral effective population size.
