Point 3) They say chances are very low of the mutated plamid naturally occuring, and give a number (unclear from where) of 1 x10 to the 12th. Well, of couse chances are very low. That is why bacteria are so darned good for observing natural selection. With their short generation time, and logarithmic growth phase, even unlikely events can occur with reasonable frequency. If you have, say, 10 (a very small number) of bacteria exposed to a new environment, over the course of a few DAYS, there will be BILLIONS of daughter cells exposed to the new environment, giving plenty of opportunity for a new mutation to occur and be amplified.

The reference mentioned above suggests that there was some sort of adaptation. How did the information for the adaptation get transferred from one generation to the next? If the bacteria get taken out of their nylon-only environment and get put in an environment of plentiful multiple food sources, do they continue to feed on the nylon? I stand by my original statement that they were waiting around for the nylon. --[[User:Descartes|Descartes]] 14:27, 23 March 2007 (EDT)
