Similar Data, Different Conclusions

By Ashley P. Taylor | February 23, 2016

By tweaking certain conditions of a long-running experiment on E. coli, scientists found that some bacteria could be prompted to express a mutant phenotype sooner, without the “generation of new genetic information.” The resulting debate—whether the data support evolutionary theory—is more about semantics than science.
