I think mine was the only post that mentioned Lamarck (took me ages to find it 'cos I missed the 'c' out). It was the one-liner "Epigenetic changes ?"

I wondered when someone would pick up on someone else's recent "inheritance of acquired characterists".

I quite like to bring it up in these discussions because although the Lamarck was wrong in the wider sense I still remember the outright mockery with which my paleontology professor recounted his (Lamarck's) theory. I wonder just how much sooner epigentic changes would have been recognised at a molecular level if researches had risked mockery and dared to do some experiments earlier.

With people like Pete around one has to be careful to stick to a measured scientific approach.
