Which of the following has been shown to cause speciation most rapidly? Speciation is the evolutionary process by which populations evolve to become distinct species.The biologist Orator F. Cook coined the term in 1906 for cladogenesis the splitting of lineages as opposed to anagenesis phyletic evolution within lineages. Charles Darwin was the first to describe the role of natural selection in speciation in his 1859 book On the Origin of Species. In evolutionary biology adaptive radiation is a process in which organisms diversify rapidly from an ancestral species into a multitude of new forms particularly when a change in the environment makes new resources available alters biotic interactions or opens new environmental niches. Starting with a single ancestor this process results in the speciation and phenotypic adaptation of an ... Allopatric speciation (from Ancient Greek ἄλλος allos meaning "other" and πατρίς patris "fatherland") also referred to as geographic speciation vicariant speciation or its earlier name the dumbbell model : 86 is a mode of speciation that occurs when biological populations become geographically isolated from each other to an extent that prevents or interferes with gene flow. It has been suggested that in some cases the speciation process has taken place because of the incompatibility caused by this bacteria. Two wasp species Nasonia giraulti and N. longicornis carry two different strains of Wolbachia. Crosses between an infected population and one free from infection produces a nearly total reproductive isolation ... However much less support for this view is shown today since the hypothesis has been tested repeatedly through experimental research and the results have been equivocal at best. [further explanation needed] Speciation by genetic drift is a specifi...
