Just before you go, perhaps you can, from a geneticist's point of view, answer this.....?
If it took 1000's of generations for the Ecoli to develop the ability to take in citrate how did the first creature that spontaneously burst forth into life (to start the process of evolution) actually survive as surely it would take more than 100 000's of generations to develop the ability to take in anything?
