The process of heredity may have more levels of actors in it than just the DNA itself. An interesting notion that seems logical; a case of living processes employing various different strategies in parallel, which would seem a plausible result of a process of random selection based on environmental fitness.
Chris DNA can't explain all inherited biological traits, research shows http://www.sciencedaily.com/releases/2015/04/150402161751.htm Characteristics passed between generations are not decided solely by DNA, but can be brought about by other material in cells, new research shows. Scientists studied proteins found in cells, known as histones, which are not part of the genetic code, but act as spools around which DNA is wound. Histones are known to control whether or not genes are switched on. Quoting two paragraphs from the article here: Researchers found that naturally occurring changes to these proteins, which affect how they control genes, can be sustained from one generation to the next and so influence which traits are passed on. The finding demonstrates for the first time that DNA is not solely responsible for how characteristics are inherited. It paves the way for research into how and when this method of inheritance occurs in nature, and if it is linked to particular traits or health conditions. It may also inform research into whether changes to the histone proteins that are caused by environmental conditions -- such as stress or diet -- can influence the function of genes passed on to offspring. -- You received this message because you are subscribed to the Google Groups "Everything List" group.
