However, because mutations are rare (else a species would dissappear in no time at all) the first mutation would have to spread itself to other individuals in the species. The problem with spreading the mutation is genetics. Each time it spreads, the mutation only has one chance in two to survive (and no, this has nothing to do with survival of the fittest and all that nonsense). So for a mutation to spread would be pretty difficult (that's one of the reasons for evos developing punk-eek). While you could be having other mutations going on in other individuals, this would not add to the mutations in the group with the other mutation because of the laws of genetics. Even if these two sets of mutatated genes were two be resident one in the father and one in the mother of a child - the child would only inherit one of the genes because of the laws of genetics. The article is therefore absolute hogwash.Bad model. I was asking tallhappy earlier why sex is important. It's important because every individual of a sexual species is totally unique. This makes having more than one experiment going on a piece of cake.
There are all kinds of mutations in all kinds of genes going around in a sexual species at any given time. Your model is still too serial. There are probably other problems because my eyes glaze over when I read your dense blue paragraphs. Are you allowing for recessive genes? You have more genes to give your children than you may be expressing.
A population is a cloud of individual genomes about a central average. Selection can move the average if things change. Think of that cloud as a sphere. The rightmost 40 percent gets lopped off. Now the center of mass has "moved."
BTW - the above is one of the many things in which Darwin has been thoroughly refuted. He thought that the differences of the parents "melded" in the progeny.Darwin wrote before Mendel. Anyway, the differences of the parents do meld in the progeny, but only overall, not in the micro traits.
It is not a model. Mendellian genetics is science. The fact that Darwin wrote before Mendel changes nothing. He still was wrong and he based his theory on something which has been scientifically proven to be wrong. Genes do not "meld" as they would be required to do according to Darwin. This makes evolution practically impossible.
