Journal ArticleDOI
A local flora and the biological species concept
TL;DR: A local flora is analyzed to determine whether polyploidy, apomixis, hybridization, and other deviations from regular sexual reproduction are sufficiently frequent in plants to make the biological species concept illusory, validating use of the sympatric situation as yardstick for the ranking of allopatric populations.
Journal ArticleDOI
Philosophical Foundations of Classical Evolutionary Classification
TL;DR: Application of the Popperian philosophy of the demarcation and methodology of science to classification suggests that a major task is the development of severe tests of falsification by which classifications can be tried.
Journal ArticleDOI
Is dispersal neutral
Winsor H. Lowe,Mark A. McPeek +1 more
TL;DR: A tighter empirical connection between the ecological and evolutionary forces that shape dispersal will enable richer understanding of this fundamental process and its role in community assembly.
Journal ArticleDOI
Latitudinal variation in genetic divergence of populations and the potential for future speciation
Paul R. Martin,John K. McKay +1 more
TL;DR: Results suggest that lower latitude populations within species exhibit greater evolutionary independence, increasing the likelihood that mutation, recombination, selection, and/or drift will lead to divergence of traits important for reproductive isolation and speciation.

Goldilocks Meets Santa Rosalia: An Ephemeral Speciation Model Explains Patterns of Diversification Across Time Scales.

TL;DR: Current understanding of speciation rates is reviewed, focusing on studies based on the fossil record, phylogenies, and mathematical models, and it is suggested that instead of being contradictory, differences in Speciation rates across different scales can be reconciled by a common model.
