Re:genes, not genomes (Score 1)

As it turns out, many scientists now believe that the holy grail may revolve around what is known as "epigenetics". This refers to the methylation, and otherwise secondary modifications present on the DNA. This is thought to control transcription of genes, and promote widespread changes throughout the genome. Recently, it was shown that such characteristics are actually transfered from parent to offspring (by mechanisms completely unknown). This essentially makes epigenetics a sort of "meta-code", adding additional information on top of the already present DNA.
