NO CITRATE EVOLUTION. “Despite this potential, none of the 12 LTEE populations evolved the capacity to use the citrate that was present in their environment for over 30,000 generations. During that time, each population experienced billions of mutations, far more than the number of possible point mutations in the ≈4.6-million-bp genome. It must be difficult, therefore, to evolve the Cit+ phenotype, despite the ecological opportunity.”
