Jean Baptiste de Lamarck (1744-1829) maintained that characteristics that were acquired during an organism's lifetime are passed on to its offspring. This theory, known as Lamarckian inheritance, was later completely discredited. However, recent progress in epigenetics research suggests it needs to be reexamined in consideration of DNA methylation. In this article, I summarize our observations, which support Lamarckian inheritance. Initial experiments indicate that (1) artificially induced demethylation of rice genomic DNA results in heritable dwarfism, and (2) cold stress induces extensive demethylation in somatic cells of the maize root. Based on these results, I propose the hypothesis that traits that are acquired during plant growth are sometimes inherited by their progeny through persistent alteration of the DNA methylation status. (author abst.) I wonder how this relates to adaptive mutagenesis http://www.pubmedcentral.nih.gov/articlerender.fcgi?artid=1206667 which has been rather controversial http://www.genetics.org/cgi/content/full/165/4/2319 ben On Wed, Dec 3, 2008 at 11:11 AM, Richard Loosemore <[EMAIL PROTECTED]> wrote: > > Am I right in thinking that what these people: > > http://www.newscientist.com/article/mg20026845.000-memories-may-be-stored-on-your-dna.html > > > are saying is that memories can be stored as changes in the DNA inside > neurons? > > If so, that would upset a few apple carts. > > Would it mean that memories (including cultural adaptations) could be passed > from mother to child? > > Implication for neuroscientists proposing to build a WBE (whole brain > emulation): the resolution you need may now have to include all the DNA in > every neuron.
