Darwinism: Science fiction


There is a book entitled “Selective Sweep” from D. Nurminsky.

The first paragraph is this:

“Positive selection is the driving force for the adaptation of organisms

to an ever-changing environment, and it leads to adaptive evolution and in

some cases to speciation. When selective pressure is applied to individuals
based on their phenotype, it ultimately leads to the changes in the underlying
genetic content of the population. The creatures that carry a more useful
genotype would outcompete their peers, resulting in the fixation of beneficial
allele(s) in the population with concomitant removal of inferior alleles.
This process of selective sweep extends positive selection to the nucleotide
level and therefore comprises the essence of Darwinian evolution. The genes
that are subject to selection are usually found in the context of a chromosome.
The adjacent genomic segments are physically linked to the selected
genes and are therefore dragged to fixation along with the beneficial allele,
or are discarded with the less fit alleles during the process called genetic
hitchhiking. In some organisms, recombination can eventually separate the
selected allele from adjacent loci; hence the strength of hitchhiking decreases
with the distance from the selected locus. When recombination rates are
very low, hitchhiking can drag to fixation extended regions of the genome or
even entire chromosomes. In bacteria, the whole haploid genome represented
by a single chromosome is driven to fixation during hitchhiking, which leads
to rapid differentiation and speciation.”

Good example of the confusion between SCIENCE with this SCIENCE FICTION.

A plausible but not proven story (like creationism or teological nature).

The first sentence is only based in faith. Faith in a ghostly “positive selection” (you never find a agreement between darwinist what selection is).

Adaptive evolution: We want to find an explanation for evolution. This is clearly not one. Adaptation is that every organism is adapted to their environment. It exists because it is adapted. So, adaptive evolution is just a semantic trap. It is empty of scientific value.

“The creatures that carry a more useful
genotype would outcompete their peers, resulting in the fixation of beneficial
allele(s) in the population with concomitant removal of inferior alleles”. It is just science fiction, because this affirmation  was never proved. There is genomic flexibility that allows the entire specie or population to be adapted to different circumstances, but this not implies the “removal of inferior (what is this?) alleles”. Just unsustainable story.

“This process of selective sweep extends positive selection to the nucleotide
level and therefore comprises the essence of Darwinian evolution.” What is selection? You never find agreement. It is not supposed that there is “differential reproduction”? If it is true, this is a result and not the cause. If it is the “pressure” of environment this “pressure” act in the organismical level, not at genes level.  Furthermore, darwinian essence is the economical justification of superior people and the free market theories as we saw. Of course, Darwin was thinking in selection practiced by farmers and pets.

“The adjacent genomic segments are physically linked to the selected
genes and are therefore dragged to fixation along with the beneficial allele,
or are discarded with the less fit alleles during the process called genetic
hitchhiking”. This fantastic description has no sustain (again) in reality. Genomes (it is known) that are mosaic of genes. Eukariotic genomes are built by virus, bacterial and archaeal sequences. Horizontal gene transfers, epigenetic mechanisms and the genome flexibility can not be explained by this obsolete and oversimplified description. The same happens with the following sentences…

In summary, this unreal and not scientifical explanations and semantic traps are part of the “great” and “solid” darwinian theory.
