Speciation: Dobzhansky–Muller incompatibilities, …
There has been a wealth of books and monographs on the topic of speciation over the last 150 years, many of them primarily or partly concerned with genetics. Although lacked a clear understanding of the mechanisms of heredity, his work nonetheless remains relevant to our current understanding of speciation genetics. In particular he understood speciation to result as a consequence of divergence by natural selection between populations. The relative importance of natural selection and drift in speciation remains an important topic. The incorporation of Mendelian genetics and Darwinian evolution occurred in the early 20th century, and one of the pioneers was a Russian-American biologist, Dobzhansky, who incorporated both field and laboratory studies into his work on speciation. remains a classic and is well worth reading. In the second half of the 20th century, speciation biology was dominated by the writing of Ernst Mayr, notably , which strongly emphasized divergence in allopatry. However, a contrasting view can be seen among plant biologists, for example in , with a much stronger emphasis on hybridization and gene flow during speciation. In the early 21st century, the perspective of the botanists seems more contemporary, with a renewed interest among zoologists in the role of hybridization during speciation. Perhaps the single most comprehensive treatment of speciation in recent times is the book , offering a remarkable overview of the field. Nonetheless, the authors’ perspective on speciation contrasts with a shift in emphasis in recent years toward the importance of ecology, exemplified in and , and from a more theoretical perspective, as in .

Several recent papers lend the authority of William Bateson to the genic hypothesis, referring to the “Bateson- Dobzhansky- Muller hypothesis.” All these papers cite a 1996 paper that, in turn, cites a 1909 paper of Bateson.
