Journal ArticleDOI
Speciation and ecology revisited: phylogenetic niche conservatism and the origin of species.
TL;DR: It is suggested that it is the tendency of lineages to maintain their ancestral ecological niche and their failure to adapt to new environments which frequently isolates incipient species and begins the process of speciation.
Journal ArticleDOI
A neo-darwinian commentary on macroevolution.
TL;DR: The neo-Darwinian synthesis that resulted from the integration of Mendelian genetics into evolutionary theory has dominated evolutionary biology for the last 30 to 40 years, due largely to its agreement with a huge body of experimental and observational data.
Book ChapterDOI
Suture-Zones of Hybrid Interaction Between Recently Joined Biotas
TL;DR: From a study of the geographic occurrences of contemporary hybridization among North American animals, it has become apparent that most of the hybrids are produced in a few relatively localized zones, with little hybridizing in the vast areas between these zones of mixing.
Journal ArticleDOI
Molecular systematics of the Eastern Fence Lizard (Sceloporus undulatus): a comparison of Parsimony, Likelihood, and Bayesian approaches.
Adam D. Leaché,Tod W. Reeder +1 more
TL;DR: An extensive phylogenetic analysis of the wide-ranging and geographically variable Eastern Fence Lizard suggests "S. undulatus" represents at least four lineages that should be recognized as evolutionary species.
Journal ArticleDOI
Genetic models of adaptation and gene flow in peripheral populations.
TL;DR: A general conclusion is that disruption of gene flow can cause evolutionary divergence, perhaps leading to speciation, in the absence of contributions from random genetic drift.
