Journal ArticleDOI
What, if anything, is sympatric speciation?
TL;DR: It is argued that testing whether a case fits a particular definition is less informative than evaluating the biological processes affecting divergence, and that this context can be better understood by modelling and measuring quantities, such as gene flow and selection, rather than assigning cases to discrete categories like sympatric and allopatric speciation.
Journal ArticleDOI
The genomics of speciation in Drosophila: diversity, divergence, and introgression estimated using low-coverage genome sequencing.
TL;DR: It is concluded that chromosomal rearrangements have been vital to the ongoing persistence of these species despite recent hybridization and serves as a proof-of-principle on how whole genome sequencing can be applied to formulate and test hypotheses about species formation in lesser-known non-model systems.

A succession of paradigms in ecology: Essentialism to materialism and probabilism
TL;DR: Lewontin this article suggests that the emerging evolutionary worldview was incompatible with the philosophical tradition, stretching back to the Greeks, which, although patently metaphysical, still dominated nineteenth century thought: viz. Platonic idealism and Aristotelian essentialism.

Are many plant species paraphyletic
Loren H. Rieseberg,Luc Brouillet +1 more
TL;DR: Many plant species are likely to be paraphyletic, and predictably a species classification based on the criterion of monophyly is unlikely to be an effective tool for describing and ordering biological diversity.
