I dont think FROM Lamarkian terms as SJGOULD did about genetic (re)engineering(there is a difference in my mind between genetic engineering and reverse genetic engineering) but the lattter will only begin to exist really after some more advances in nanotechnology DO come up against any nanoecology. Lets hope that being introduced is enough for the limit to have already been reached. The difference of independence and logic are not the same things and result in confusions about what is natural or not (otherwise) etc.
