Tempo and mode of speciation in the Baja California disjunct fish species Anisotremus davidsonii.

abstract：:The Neolithic transition has been widely debated particularly regarding the extent to which this revolution implied a demographic expansion from the Near East. We attempted to shed some light on this process in northeastern Iberia by combining ancient DNA (aDNA) data from Early Neolithic settlers and published DNA dat...
