TOE and the Reasons for Doubt

Hi Peg, So therefore, any change to a theory that improves its accuracy is a good thing. The theory that Darwin coined was that Descent with Modification through the process of Natural Selection resulted in the development of new species. Darwin on Line
Origin of Species editions
Darwin, C. R. 1859. On the origin of species by means of natural selection, or the preservation of favoured races in the struggle for life. London: John Murray. [1st edition](you can read the entire text and compare it to later editions to see what the changes are)Curiously, evolution still holds that descent with modification by means of natural selection does occur, not just in life in general, but in speciation events where new species arise. It's just that a more accurate description now includes several things not known in Darwins time.This is similar to the change in the theory of gravity from Newton to Einstein, the new theory encompasses the old theory (and defaults to it in certain circumstances) but it is more accurate as a description of (currently) observed behavior.Enjoy.

Hi Peg, I think you are becoming more and more confused.Your skin (and other) cells are constantly reproducing in the same way that single cell eukaryote organisms reproduce. Skin cells are constantly dying and being replaced by new cells.Skin - Wikipedia

Cells are formed through mitosis at the basale layer. The daughter cells (see cell division) move up the strata changing shape and composition as they die due to isolation from their blood source.

Mitosis - Wikipedia

Mitosis is the process by which a eukaryotic cell separates the chromosomes in its cell nucleus into two identical sets in two nuclei.[1] It is generally followed immediately by cytokinesis, which divides the nuclei, cytoplasm, organelles and cell membrane into two cells containing roughly equal shares of these cellular components. Mitosis and cytokinesis together define the mitotic (M) phase of the cell cycle - the division of the mother cell into two daughter cells, genetically identical to each other and to their parent cell.

It takes something like 20 years, iirc, for your whole body to be replaced with new cells by this simple method of reproduction.Of course this process is "guided" by the DNA in the cells, but you have the same process in bacteria as mammal skin.Enjoy.
