int that the funda- mental genetic mechanism of speciation is relatively uniform and stereotyped and, in particular, that the ‘allopatric‘ model of its geographic component is universally valid. Certainly, this has been a rather generally accepted viewpoint on the part of students of vertebrate speciation. Wo978-94-010-2250-7978-94-010-2248-4作者: 變化 時間: 2025-3-23 11:02
