Journal ArticleDOI
Punctuated equilibria; the tempo and mode of evolution reconsidered
Stephen Jay Gould,Niles Eldredge +1 more
TL;DR: It is argued that virtually none of the examples brought forward to refute the model of punctuated equilibria can stand as support for phyletic gradualism; many are so weak and ambiguous that they only reflect the persistent bias for gradualism still deeply embedded in paleontological thought.
Journal ArticleDOI
Phenotypic Plasticity and the Origins of Diversity
TL;DR: Much recent progress has been made toward integrating developmental and evolutionary biology, especially in vertebrate morphology, developmental genetics, and molecular biology, though an unfortunate one because it seems to imply that the main effect of developmental constraints is that of "Developmental constraints".
Journal ArticleDOI
Stabilizing selection and the comparative analysis of adaptation.
TL;DR: A model of adaptive evolution on a macroevolutionary time scale that includes the maintenance of traits at adaptive optima by stabilizing selection as the dominant evolutionary force is presented.
Journal ArticleDOI
Evolution and Taxonomy of Positive-Strand RNA Viruses: Implications of Comparative Analysis of Amino Acid Sequences
TL;DR: It is hypothesized that all positive-strand RNA viruses and some related double-stranded RNA viruses could have evolved from a common ancestor virus that contained genes for RNA-dependent RNA polymerase, a chymotrypsin-related protease that also functioned as the capsid protein, and possibly an RNA helicase.
Journal ArticleDOI
When Are Peripheral Populations Valuable for Conservation
Peter Lesica,Fred W. Allendorf +1 more
TL;DR: Under some circumstances, conservation of peripheral populations may be beneficial to the protection of the evolutionary process and the environmental systems that are likely to generate future evolutionary diversity.

Journal ArticleDOI
Statistical genetics and evolution
TL;DR: The deductive approach, to which the author shall confine himself here, involves many questions that can only be settled by observation and experimental work on natural populations and that a remarkable resurgence of interest in such work is in progress.
