==Did nylon digesting bacteria DEVOLVE so that they could utilize a new food source?
According to Creation Scientists, bacterial plasmids seem to be adaptive elements built in by the creator so bacteria can adapt to many environments while “maintaining the integrety of the main chromosome.”
==Did citrate plus e.coli DEVOLVE so that they could digest citrate?
Has the ability of the e.coli to adapt to a new environment, such as constantly being exposed to citrate, been ruled out? Again, from what I have read, even the scientists who conducted the experiment aren’t sure what’s going on: “Lenski’s team is still working to understand ‘just what that earlier change was, and how it made the . . . mutation possible.’”
==Do populations subjected to the selective pressure of heat stress DEVOLVE such that they can better survive at higher temperatures?
Again, what’s your evidence that their ability to adapt is NOT built right in???
The answer is, it ISN'T due to a mutation. This ability was already in the genome.
This conclusion is entirely consistent with observation.
The ability to adapt IS built right in! Wow. Finally you have stumbled upon the truth.
Living systems are capable of adapting to selective pressure by means of natural selection of genetic variation!
In the case of heat stress, a particular population of bacteria subjected to heat stress went through every possible single change permutation of a particular gene until it produced the high heat protein that eventually dominated the entire population. Now if every possible combination of a single change was attempted, how is evolution supposed to be “random”?
