NS is not responsible for new genes


now a new species has new genes/traits
thus if natural selection is not responsible for new genes then it cannot be responsible for the origin/generation of species as colin leslie dean has shown

NS does not allow the increase of genetic information so as to creatre a new generation of species.


thus natural selection is wrong as an evolutionary theory for the generation of new species as colin leslie dean has shown

NS is only about the passing on of genes/traits already present and thus cant account for the origin of new species ie new genes/traits

it is logically and definitionaly impossible for NS to generate new species ie with new /genestraits never seen before as NS is only about the passing on of already present genes/traits

definition from this site
It is the process by which heritable traits that increase an organism’s chances of survival and reproduction are favoured than less beneficial traits. Originally proposed by Charles Darwin, natural selection is the process that results in the evolution of organism

Now NS is invalidated by the fact of speciation as NS only deals with triats already present and cant deal with the generation of new species
. A new species has completely new traits which were not in an antecedent so the antecedent species could not have passed them on
NS is all about the transmission of already acquired traits
if evolution can take place by speciation i.e. a new species has new traits that are not present in the antecedent species thus NS is invalid as it cannot account for speciation

This does not make sense to me. Genetically, I can trace where a certain gene was either introduced (thru transposons, drifting, virius, duplication/mutation) that could change something that has a phenotypically observeable trait into another species for labeling. And depending on how that trait is passed on to offspring and how well it is able to integrate into the germline genome, will give it stability for generations.
