Journal ArticleDOI
Evolution of a Species' Range
TL;DR: This work studies the process using simple models that track both demography and the evolution of a quantitative trait in a population that is continuously distributed in space to dramatically shift the balance between gene flow and local adaptation, allowing a species with a limited range to suddenly expand to fill all the available habitat.

Evolutionary significance of local genetic differentiation in plants
Yan B. Linhart,Michael C. Grant +1 more
TL;DR: The study of natural plant populations has provided some of the strongest and most convincing cases of the operation of natural selection currently known, partly because of amenability to reciprocal transplant experiments, common garden work, and long-term in situ manipulation.
Journal ArticleDOI
Sibling species in the sea
TL;DR: A large number of abundant, well-studied, or economically important taxa have recently been shown to be complexes of sibling species, and the broad habitat and geographic distributions characteristic of many marine species require reevaluation.
Journal ArticleDOI
Mitochondrial DNA and two perspectives on evolutionary genetics

TL;DR: In this article, a comparative study of mtDNA and nuclear DNA variability is presented, with emphasis on mtDNA's uniparental and apparently haploid mode of inheritance, which makes mtDNA a superb tool for building trees and time scales relating molecular lineages at and below the species level.
Journal ArticleDOI
Hybrid Origins of Plant Species
TL;DR: Experimental, theoretical, and empirical studies of homoploid hybrid speciation suggest that it is feasible, although evolutionary conditions are stringent, and hybridization may be important as a stimulus for the genetic or chromosomal reorganization envisioned in founder effect and saltational models of speciation.
