How to make an embryo (Introduction)
We still don't know, but this review on an ID website gives a reliable and fascinating insight as to how complicated it is. The discussion proposes that DNA doesnot carry all the instructions and describes someof the other known mechanisms, which so far are just a few. > > http://www.evolutionnews.org/2011/06/beyond_the_genome_a_non-reduct047021.html-"Head cells must turn on different genes from tail cells, and they "know" which genes to turn on because they are receiving information with respect to their spatial location from outside of themselves -- and, thus, beyond the remit of the DNA sequence."-Heh. They make a similar argument to Dawkins here that the DNA is a deterministic unit--utterly wrong. Though I know very little about embryonic development, once a cell lives and is manufacturing proteins, you get a very dynamic environment. DNA serves only as "read-only" memory in cells, anything that comes after this is quite clearly the product of various interactions of proteins and cell-stimuli.

\"It is, brahmin, because of attachment to views, adherence to views, fixation on views, addiction to views, obsession with views, holding firmly to views that ascetics fight with ascetics.\"
