[[Jerry Coyne]] and [[H. Allen Orr]] in ''Speciation'' suggest that most laboratory studies of allopatric speciation are also examples of peripatric speciation due to their small population sizes and the inevitable divergent selection that they undergo.<ref name="Speciation"/>{{rp|106}} Much of the laboratory research concerning peripatry is inextricably linked to [[founder effect]] research. Coyne and Orr conclude that selection's role in speciation is well established, whereas [[genetic drift]]'s role is unsupported by experimental and field data—suggesting that founder-effect speciation does not occur.<ref name="Speciation"/>{{rp|410}} Nevertheless, a great deal of research has been conducted on the matter, and one study conducted involving [[Population bottleneck|bottleneck]] populations of ''[[Drosophila pseudoobscura]]'' found evidence of isolation after a single bottleneck.<ref>{{Citation |title=The Founder-Flush Speciation Theory: An Experimental Approach| author=Jeffrey R.

Most of the studies also conducted experiments on vicariant speciation as well. The "replicates" column signifies the number of lines used in the experiment—that is, how many independent populations were used (not the population size or the number of generations performed).<ref name=AO&ABF2002/>
