An evolutionary biologist examined the relative fitness of Escherichia coli bacteria grown for 2000 generations, about 300 days, at stressful acidic pH 5.5 and their parental generation, grown and preserved at pH 7.2. Both types were later grown together in an acidic medium, and their relative fitness was computed. The experiment was replicated with 6 different lines of E. coli, giving the following relative fitness values: 1.24 1.22 1.23 1.24 1.18 1.09 A relative fitness of 1 indicates that both bacteria types are equally fit. A relative fitness larger than 1 indicates that the acid-evolved line is more fit than the parental line kept at neutral pH when both are grown in acidic conditions (that is, the acid-evolved bacteria grew the most). Do the data provide evidence that bacteria evolved in acidic pH are better adapted to acidic conditions, at a significant level a = 0.05?
