On the origin of species by varietal selection


Figure 1
As we approach the 150th anniversary of the publication of Charles Darwin's seminal work, it is appropriate that we again discuss speciation mechanisms. Speciation often occurs when populations become separated from each other. Separation may be geographically obvious but it may also take more subtle forms. One such example is seen in the preferences for different host plants in different populations of parasitic species, as has been studied by Thorogood et al. (Bristol University and Natural History Museum, London, pp. 1005–1014). Orobanche minor is a parasite with a very broad host range, but within that range specific varieties or sub-species of the parasite may exhibit specific host preferences. The authors have examined the parasitic behaviour of O. minor var. minor and O. minor ssp. maritima that usually infect, . . . [Full Text of this Article]
