Anyone want to add in the simple amazing fact that a single cell of a living organizim, be it human, animal or plant. Contains the complete instruction set to "build" the entire organizim. Yet when the cells divide only certain ones become cells of one type while other cells become another type. Yet every single cell holds the entire instruction set to build the entire "thing". Now you scientific types please explain to me the process that allows the cells to change into the required cell type. By what method does this happen?

Genes can be switched on and off through chemical groups on the histones (proteins which the DNA is bent around) which can making reading the DNA easier or more difficult. These groups can be changed by enzymes which react to the chemicals that are given off by other cells in the organism. Adding methyl groups to the cytosine nucleotide can also switch off a gene. Again the cell has enzymes that can do this and those enzymes react to the environment of the cell.

True creationizm would have to envolve taking an egg (single cell) from one animal type and by manipulating the protiens cause that egg to spawn an offspring that is seperate from the original genus of the donor egg. Ie taking a human egg and my switching the protiens and fertilizing it you get say a snake or a dog. Then you would have a scientific argument that any and all creatures could have evolved from one source, thus giving creadence to the Evolution Theory.

I once read about a long-running experiment where a scientist kept E. Coli bacteria under extreme conditions for tens of thousands of generations and followed their adaption. After about a decade now one of the colonies has actually splitted up into two different kind of bacteria, living in symbiosis.

But the kicker is that you must be able to prove that you can initiate life by having the right mix of chemicals and conditions, thus creating the right "chains" to exist to form the basis of a DNA structure to form.

Evolution and abiogenesis are two completely different subjects. One of the postulates of evolution is at some time there was one organism from which all other organisms evolved. Evolution doesn't say anything about how that organism got there.

imo, it's useless to discuss anything!

because no one can prove it!
