Yet, in many cases, statistical dating of evolutionary events indicated that the breakup of land masses occurred tens of millions of years before some species» ancestors evolved, bringing into question the validity of vicariance methods. (sciencedaily.com)
This view, called «vicariance biogeography,» became the dominant paradigm. (sciencedaily.com)
The new study compares the theories of jump dispersal and vicariance in a new computational program developed by Nicholas J. Matzke, a postdoctoral fellow at the National Institute for Mathematical and Biological Synthesis. (sciencedaily.com)
