Microcephaly genes evolved adaptively throughout the evolution of eutherian mammals.

abstract：BACKGROUND:Past events like fluctuations in population size and post-glacial colonization processes may influence the relative importance of genetic drift, migration and selection when determining the present day patterns of genetic variation. We disentangle how drift, selection and migration shape neutral and adaptive...
