Example sentences for: speciation

How can you use “speciation” in a sentence? Here are some example sentences to help you improve your vocabulary:

  • I agree with Coyne and Orr that the theory and evidence for speciation by sexual selection is one of the most important advances in speciation studies, but it is important to recognize that the evidence consists mostly of correlations between diversification rates and indices of the likely strength of sexual selection; as Coyne and Orr note, there are no cases in which we understand just how sexual selection has caused speciation.

  • Few topics in biology are as simultaneously encompassing, complex, and controversial as the origin of species, i.e., speciation.

  • But there is another possibility, one that can cause the speciation between the two populations to proceed.

  • However, the amount of evidence is hardly on a par with, say, the evidence for allopatric speciation.

  • Since the basic single-copy repertoire of dispersed aromatic-pathway genes shown in Figure 2for Synechocystis (Ssp) is representative of other cyanobacteria such as Synechococcus (Syn) and Prochlorococcus (Pmu) and is also present at dispersed extra-operonic loci of Anabaena and Nostoc , an obvious possibility would seem to be that the genes of the supraoperon originated by LGT in a common ancestor of Anabaena and Nostoc . If so, speciation was followed by different species-specific gene-insertion events.
