Rossum - Okay - I’m sorry I didn’t address your ‘complete harmony’ issue. Yes I did read all of your posts completely. I will not use those words ‘complete harmony’ next time. May I call it a “system”. So, “from one cell to a [how many cells in the human body, I’m guessing a hundred billion?] system”. I didn’t answer because I thought to myself, “what kind of convoluted argument would have to resort to the task of taking the human body, an unspeakably coordinated and awesome system, and have to discount it, saying it’s not that great because it gets migraines.” I didn’t realize you wanted me to address it but there, those are my feelings on this.Only if we have complete and correct information to put into the equation - GIGO.
That depends on what species you are talking about. The mutation rate in eukaryotes is in generally 10[sup]-4[/sup] to 10[sup]-6[/sup] mutations per base pair per generation, and for bacteria the rate is around 10[sup]-8[/sup] per base pair per generation. (Source: Wikipedia)
The rate of natural selection is driven by the degree of matching between the organism and its environment. In order to supply the data you want I require a detailed description of every environment in which any of our ancestors ever lived. You are asking for the name of Cain’s wife here.
A single mutation can affect a very large number of cells, for example polydactyly: midwestrocklobster.com/011007/avatar_lg.jpg
As I have pointed out, the cells of the human brain are not in “complete harmony”, they are reasonably good harmony. Migraines and epilepsy would not occur is the brain cells all operated in “complete harmony”. If you are not going to bother to read my posts, then there is not much point in my posting.
I am not speculating on the process. We can observe random mutations here and now. We can observe natural selection here and now. These two processes are not “speculation” but can be observed here and now, just like fossils. From current observations we can make resonable inferrences. I have never observed a live non-avian dinosaur, but it is a reasonable inference from the observed fossils that there were once live non-avian dinosaurs. Avian dinosaurs are readily observable which is another strand of evidence tending to confirm the inference.
We observe that brain development is controlled by genes. We observe that genes mutate. We observe that animal populations tend to increase to utilise all available resources. We observe that more offspring are made than are required for simply the replacement of their parent/s. We observe that there is competition for resources, and that hence there must be natural selection involving the size and complexity of an animal’s brain.
What observable, and mathematically proven, alternative do you have?

I guess if the rates I asked for where available, you or someone would have presented them. I’m not going to chase after the alleged mutation rate of a eukaryote and try to tie it and the natural selection rate and then to my question. Too much work for me, since even no full-time scientist has accomplished this. I guess if it could have been done with current means it would have.
In terms of what alternative I have: none. Same as you, I have nothing. I even suspect that what a random mutation actually is, is not even fully defined until those genetic analyses that Reggie is talking about are more developed. Yes I know you probably disagree with that last statement but I stand by it.
The difference with me, is that I don’t assert claims, that a single-celled system evolved to a 10 billion human cell system, and can’t back it up mathematically in a hundred and fifty years, despite modern math and computers. I’ll check back in another few years and if more progress is made I’ll change my mind. You are free to believe what you like, and so can I.
