Entropy is Still Choking on Natural selection
I don't know why this is so difficult but the "random" in "random mutations" just means they are strictly a chance, as in happenstance, occurrence. They are accidents, errors and mistakes.
The first step in selection, the production of genetic variation, is almost exclusively a chance phenomenon except that the nature of the changes at a given locus is strongly constrained. Chance plays an important role even at the second step, the process of elimination of the less fit individuals. Chance may be particularly important in the haphazard survival during periods of mass extinction.- Ernst Mayr "What Evolution Is"That is it. Errors and mistakes happen during copying. Accidents occur when an organism is subjected to some environmental mutagen.
Nothing is planned. It is all spontaneous.
Causes of mutations
What Darwin called natural selection is actually a process of elimination.Page 118:
Do selection and elimination differ in their evolutionary consequences? This question never seems to have been raised in the evolutionary literature. A process of selection would have a concrete objective, the determination of the “best” or “fittest” phenotype. Only a relatively few individuals in a given generation would qualify and survive the selection procedure. That small sample would be only to be able to preserve only a small amount of the whole variance of the parent population. Such survival selection would be highly restrained.
By contrast, mere elimination of the less fit might permit the survival of a rather large number of individuals because they have no obvious deficiencies in fitness. Such a large sample would provide, for instance, the needed material for the exercise of sexual selection. This also explains why survival is so uneven from season to season. The percentage of the less fit would depend on the severity of each year’s environmental conditions.Artificial selection = the selection definition whereas natural selection = the elimination definition. The difference is huge, as Mayr describes. Natural selection could NEVER produce the different breeds of dogs. However remove humans and natural selection will get rid of those breeds.
It appears that evos are too dim to grasp any of that.
“Natural selection is therefore a result of three processes, as first described by Darwin:
Variation
Inheritance
Fecundity
which together result in non-random, unequal survival and reproduction of individuals, which results in changes in the phenotypes present in populations of organisms over time.”- Allen McNeill prof. introductory biology and evolution at Cornell University
That means that heritable variation is part of natural selection. entropy disagrees but it is an ignorant asshole and we can dismiss its uneducated opinion. I will go with the evolutionary experts who say it is part of NS.
entropy sez it doesn't care about any designer mimic. No one cares, entropy. The whole point of NS is that it is a designer mimic. And it canNOT be a designer mimic is the processes of NS are intelligently designed. NS doesn't care about the SOURCE of variation. But it cares about the TYPE.
