stasipatric speciation A rapid speciation that may occur among small breeding populations that are not completely isolated genetically or spatially. Such speciation may occur either parapatrically or sympatrically. M. J. D. White, who proposed the concept in 1978, pointed out that most species have their own unique karyotype, and suggested that the karyotype changes might have been the actual promoters of reproductive isolation.

stasipatric speciation Rapid speciation, by chromosomal mutation, that may occur among small breeding populations that are not completely isolated genetically or spatially. Such speciation may occur either parapatrically or sympatrically. M. J. D. White, who proposed the concept, pointed out that most species have their own unique karyotype, and suggested that the karyotype changes might have been the actual promoters of reproductive isolation.
