That's not a very helpful answer. Instead of using labels, could you describe what has to happen?
Deterministic selection would be the alternative to chance or random selection,as chance and random is commonly understood. Supernatural causation is out of the question,as far as science is concerned. I keep reading that natural selection is not random,but scientists do not say the alternative.
If natural selection is non-random,how should it be characterized?
I edited my reply in post 36: Organisms would have to be much more genetically changeable than they are. Mutations would have to affect many more things than just pigmentation,bodily growth,resistance to disease,or cause disease and deformation.
In something that occurs randomly, there is a fairly even statistical distribution of probability--as in a fair coin toss or distribution of cards in a game. Your chance of getting heads on any one toss is 0.5; your chance of getting a card of a particular suit on any one deal is 0.25 and mathematicians can work out the probabilities of much more complex situations. But in any case the probability is the same for every occurrence of the pattern in question.
In something that occurs non-randomly, the probability is not the same for every occurrence. Insurance companies vary their rates for automobile insurance according to the age and gender of the driver to be insured because the likelihood that there will be a claim on behalf of a 22-year old male is much greater than the likelihood of a claim from a 52-year old male or a 22-year old female. That is not random. It may still be a matter of chance, but it is not evenly distributed chance.
Natural selection refers to the uneven distribution of reproductive and/or mortality rates associated with the appearance of certain character traits in a given ecological situation. If you are familiar with the Hardy-Weinberg equations, you know how this uneven probability is calculated, and how, knowing the selective factor associated with a trait, one can calculate the change in the proportion of the population expressing that trait from one generation to the next.
I am not certain of what sort of label, other than non-random, one would apply to this. I think "differential" might be more appropriate than "deterministic". In a purely random situation, the odds are not different for one group than the other. In a non-random situation they are.
Gluadys, it seems that you don't fully understand evolution.
Please go to read "Encyclopaedia of evolution", it states that "adaptation... turns out to be slippery, sometimes even circular and paradoxical... Some biologists have even suggested eliminating the concept of adaptation altogether..."
There is NO such thing as adaptation, it's all chance mutations (+ natural selection). Richard Dawkins said there seems to be designs in the world but there is no purpose behind it. How can you say there is no purpose on one hand , and then say evolution is not by chance on the other hand ???
Besides adaptation, another deceitful concept is "evolution is non-random".
I believe those who believe evolution is non-random has been misled and deceived . I believe evolution is random, it is based on chance. Here is the reasoning:
____________________________________________________________
Suppose A is a random activity, entirely based on chance ;
Suppose B is a non-random activity and B follows and depends on A (if A does not happen, B doesn't happen) ;
Since B depends on A, then B depends on chance to a certain degree also ;
Therefore A + B is based on chance, no matter how non-random B is.
But if A follows and depends on B, then it is not.
For example, if I won the lottery 20 times, then I shall pick a beautiful house to buy. Winning the lottery 20 times is based on chance, picking a beautiful house is not by chance. But since it depends on the former, then it becomes also a matter of chance. How can you say the whole matter is not based on chance ??
Saying evolution is not based on chance, is like saying "if I won the lottery 20 times, then I shall pick a beautiful house to buy" is not based on chance because "to pick a beautiful house to buy" is non-random.
(Natural selection is certainly non-random, but mutation is based on chance)

I don't think that is what scientists mean when they say that NS is a non-random process. Random is only defined as even statistical distribution of probability in the field of statistics.
Normally random means without aim,reason,pattern or regularity.
Scientists say that is NS non-random because traits that favor survival and reproduction are much more likely to become common than traits that don't,
and scientists think that the results of NS can be predicted.
I once read an online interview with a scientist who was a former Catholic priest who said that NS is a deterministic process. The term differential does not characterize how NS acts upon genetic variants.
Well, it is. I have seen that explained many times.
Scientists do not normally use the statistical definition of random when they say that NS is non-random.
They mean that NS is cumulative and it favors the survival and reproduction of beneficial mutations or traits.
Why Natural Selection is Not Random « For the Sake of Science
<This notion that natural selection is both a non-random process and an undirected one at the same time can lead to confusion. The concept is essentially that this mechanism lends itself to increasing complexity because it builds in cumulative steps. For a step to be cumulative, it (quite obviously) must be based on the previous step. A random process does not lend itself to cumulative steps because, by definition, it is not based on anything. So in this way natural selection is non-random. But it also does not look to end in the phenotype of a tiger or a bat. It has no conscience, merely results. For this reason, it is undirected.>
Evolution by Accident
<Natural selection is a non-random process because there is a preferred outcome but mutation is, to all intents and purposes, random. This is what Jacques Monod means when he refers to evolution as a combination of chance and necessity. The "chance" is the randomness of mutation and mutations supply the raw material for evolution. The "necesssity" is the non-random process of natural selection.>
evolgen archive: Random Mutation and Natural Selection
<Natural selection is a deterministic process; a beneficial mutation will always reach fixation in an ideal population (i.e., natural selection will cause it to replace all the other alleles), and a deleterious mutation will always be lost. We have no way of saying for sure whether or not a particular nucleotide will mutate because mutation is a random process we can only assign a probability that it will mutate.>
I don't see anything in these citations that is NOT referring to statistics.
While it's true that a random process may have an even statistical distribution of different outcomes,this is not the idea of random that scientists are referring to. They are implying that NS does have aim and direction and pattern,if not purpose. It leads to predictable outcomes.
How would you know that? We've seen many times that science is the only institution where you are rewarded (hansomely!) for disproving the prevailing ideas. That's as far from a dictatorship as you can get. I hate to break it to you, but there is no supreme council of scientist who tell scientists what to believe - scientists go by the evidence.
Papias
I was not wrong when previously I said you bow down to scientists. I believe you are so impressed with the appearance of science and technology. As a consequence, you see scientists and technologists as idols and therefore you think all scientists are honest and open-minded.
But the reality is not like that. You forgot (or maybe never knew) the Christian concept of "Original Sin". The science circle is not what you think.
Read this:
A Chinese paleontologist lectures around the world saying that ..... When this conclusion upsets American scientists, he wryly comments: - excerpted from "Nature's probability and Probability's nature", by Dr. Donald E. Johnson
....but not the government. In America you .....
Scientists who doubted Theory of evolution have been persecuted.
Therefore 800 scientists declaring they doubt Theory of evolution is a big number.
(Imagine in pagan Roman Empire at the time of Nero, suppose there were 500 Christians openly professed their faith in spite of fierce persecutions, would you say 500 is a small number ???)
I have always been arguing only against atheistic evolution, there is no point for you to be an ardent defender of atheistic evolution. But you are always the first to come up to its defense and you show an extraordinary kind of hatred towards Creationism. I think this tells us something special about you.
Lepanto: Generally its door is open only to those believe in evolution. It is almost a dictatorship, rather than a democracy.

Papias
I thought initially you are a 30+ year old. But now I am more and more sure you are not. You are naive about the science circle when you thought there are no persecutions there against those who speak out against TOE. Persecutions and discrimination do exist in science circle.
800 is a significant number when you consider the persecutions and discrimination. Anyway, I reckon the arguments presented by the 800 are still better than the rest who talk like authorities outside but got not much substance inside.
It's good that you talked about the concept of "original sin", but , curiously, the only time you mentioned it was when you defend TOE.
By the way, can you prove the Chinese paleontologist does not exist ?
Papias, here are 2 of the many examples of bias in the science circle:

(1) To have a meaningful design created by chance is small.
(2) To have a structure created by chance is even smaller.
(3) To have a structure that is durable created by chance is even much smaller.
