(response to J.A. Coyne, Nature, vol. 355, p. 511, 1992) Nature. V357. P26(1) May 7, 1992 Abstract AB: Analysis of contact between two chromosomal races of house mice in northern Italy show that natural selection will produce alleles that bar interracial matings if the resulting offspring are unfit hybrids. This is an important exception to the general rule that intermixing races will not tend to become separate species because the constant sharing of genes minimizes the genetic diversity requisite for speciation.

Bird speciation in subtropical South America in relation to forest expansion and retraction. The Auk. V109. P346(12) April, 1992 Abstract AB: The climatic and geographic history of the Pleistocene and Holocene periods modified the distribution of the bird population in the South American forests. Forest birds are found dispersed in the Yungas and Paranese areas with only minimal infiltration of the Chaco woodland, indicating an atmospheric change during the interglacial periods. In the Chaco lowlands, the interactions between non-forest birds reveal the existence of presence of a forest belt along the Bermejo and Pilcomayo rivers. Kondrashov, Alexey S.. Jablonka, Eva.

Coyne wrongly asserted that neodarwinism includes allopatric evolution but not sympatric evolution. Allopatric evolution occurs among geographically isolated populations, whereas sympatric evolution occurs within one species' entire population. Both are neodarwinian since each results from natural selection of genetic variation. Also, Coyne failed to recognize that the molecular models used to illustrate how genetic changes bring on speciation are most useful when researchers acknowledge that both inherited epigenetic and genetic changes affect speciation.

He wrote this up in: Dobzhansky, T. 1973. Species of Drosophila: New Excitement in an Old Field. Science 177:664-669 2) A naturally occurring speciation of a plant species, Stephanomeria malheurensis, was observed in Burns County, Oregon. The citing is: Gottlieb, L. D. 1973. Genetic differentiation, sympatric speciation, and the origin of a diploid species of Stephanomeria. American Journal of Botany 60(6):545-553 3) In the 1940's a fertile species was produced through chromosome doubling (allopolyploidy) in a hybrid of two primrose species. The new species was Primula kewensis. The story is recounted in: Stebbins, G. L. 1950. Variation and Evolution in Plants. Columbia University Press. New York 4) Finally, two workers produced reproductiove isolation between two strains of fruit flies in a lab setting within 25 generations. I don't have the paper handy, so I can't give the species. The partial citing of the paper is: Rice and Salt 1988. American Naturalist 131:911- Dohbzhansky got a subpopulation of _D. paulistorum to speciate in his lab. The reference is: Dobxhansky and Pavlovsky, 1957 An experimentallly created incipient species of Drosophila, Nature 23: 289- 292 See also: Weinberg, et. al, 1992 Evidence for rapid speciation following a founder event in the laboratory, Evolution 46: 1214 This isn't a full paper (just a note) -- it describes what is probably speciation of a type of polychaete worm. ~~~~~~~~~~ There are two distinct strains of *Rhagoletis pomonella*, the apple maggot fly. One infests the apple, the other the hawthorn. They have different breeding times--as the fruits flower at different times--and so they do not interbreed in the real world. I do not know if they could interbreed in the laboratory. Since the fly is not found in Europe, and the apple is an import from Europe, the only presumption is that the apple strain is a speciation off the original hawthorn strain. ~~~~~~~~~~~ I do not currently have references to cite for the speciation of fish, however I have a couple for the case of rats. Genus _Rattus_ currently consists of 137 species [1,2] and is known to have originally developed in Indonesia and Malaysia during and prior to the Middle Ages [3].
