Before revision: A major goal of molecular evolutionary biology is to identify loci or regions of the genome under selection  . Correct identification allows further comprehension of the phenotypic changes responsible for adaptation and improves both our historical inference and predictive ability for understanding evolution from the past and into the future.
After revision: A major goal of molecular evolutionary biology is to identify loci or regions of the genome under selection versus those evolving in a neutral manner . Correct identification allows further comprehension of the phenotypic changes responsible for adaptation and improves both our historical inference and predictive ability for understanding evolution from the past and into the future.
