Genetic Algorithms vs. Natural Selection
-
Clueless evoTARDs think nature selects because the word
"selection" is part of natural selection.
From "What Evolution Is" page 117:
What Darwin called natural selection is actually a process of elimination.Natural selection is a process of elimination. What does that mean?:
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. {genetic algorithms are in this category}
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. {natural selection is in this category}
With biology fitness is determined by reproductive success. It is
an after-the-fact assessment. With GAs fitness is determined before
reproduction.
page 281: On natural selection being a pressure or force:
What is meant, of course, is simply that a consistent lack of success of certain phenotypes and their elimination from the population result in the observed changes in a population.
On the role of chance:
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.
It's funny watching evos continue to misunderstand the very idea
they are supposed to be defending.
So natural selection eliminates the less fit and genetic algorithms select the most fit (based on some arbitrary functions). Only imbeciles and dishonest assholes think that genetic algorithms simulate natural selection.
