Guessing can be fun… If the actual mutation rate is 1.34 mutations per genome copy per year… the genome copy contains how many potential mutations? And what are the potential beneficial mutations, compared to potential deleterious mutations? And compared to total non-deleterious? You are guessing that one in 10,000 or 1 in 100,000 mutations are beneficial, but is that based on observation or conjecture. It seems conjecture.
“About 35 million DNA base pairs differ between the shared portions of the two genomes, each of which, like most mammalian genomes, contains about 3 billion base pairs…” National Human Genome Research Institute. News.
Out of 89 million beneficial mutations occuring potentially once each, 35 million base pairs have changed? How about including a few other factors, such as deleterious mutations nullifying the beneficial one, and the necessity for two identical mutations in some cases being necessary for propogation, Or is this never necessary? And if there were only 8.9 million beneficials, how would you arrive at 35 million base pair changes to survive? not including another 5 million insertions and deletions? and not including the actual difference in size of the genomes?
“A lot more genes may separate humans from their chimp relatives than earlier studies let on. Researchers studying changes in the number of copies of genes in the two species found that their mix of genes is only 94 percent identical. The 6 percent difference is considerably larger than the commonly cited figure of 1.5 percent…The new finding supports the idea that evolution may have given humans new genes with new functions that don’t exist in chimps, something researchers had not recognized until recently.” Scientific American (Human-Chimp gene gap widens…)
So 6% of 3 billion bp is 180 million bp difference. 180 million bp had to change. Not a small number. Presumably they had to change in beneficial ways. Out of 89 million beneficial possibilities, or out of 8900 beneficial possibilities. Not including any effects from natural selection, or from non-symbiotic or antagonistic effects of simultaneous deleterious mutations, or from simple natural death under any circumstances, etc.
If the numbers are wrong, I am sure you will correct me.
