The biology of speciation.

Since Darwin published the "Origin," great progress has been made in our understanding of speciation mechanisms. The early investigations by Mayr and Dobzhansky linked Darwin's view of speciation by adaptive divergence to the evolution of reproductive isolation, and thus provided a framework for studying the origin of species. However, major controversies and questions remain, including: When i...

Ecological Knowledge, Leadership, and the Evolution of Menopause in Killer Whales

Classic life-history theory predicts that menopause should not occur because there should be no selection for survival after the cessation of reproduction [1]. Yet, human females routinely live 30 years after they have stopped reproducing [2]. Only two other species-killer whales (Orcinus orca) and short-finned pilot whales (Globicephala macrorhynchus) [3, 4]-have comparable postreproductive li...

Ecological speciation ! Or the lack thereof ? 1

Ecological speciation occurs when adaptation to different environments or resources causes the evolution of reproductive isolation. This process is now thought to be very important in the evolution of biological diversity. Indeed, support for ecological speciation is so often asserted in the literature that one can get the impression of ubiquity. Eager to ride on the coattails of this exciting ...

The ecological genetics of speciation.

Ecological interactions and the natural selection they cause play a prominent causal role in biological diversification and speciation. As a discipline, ecological genetics integrates the two components of adaptive evolution (natural selection and genetic variability) to study the mechanisms of evolution. Ecological genetics is a fruitful approach to the study of how reproductive isolation can ...

Natural Selection and Ecological Speciation in Sticklebacks

The idea that selection may be fundamental to the origin of species dates back at least to the synthesis of modern evolutionary theory, being present in the writings of Fisher (1930), Muller (1942), and Dobzhansky (1951). Nevertheless, despite almost three-quarters of a century since the idea was first proposed, little progress has been made in testing the role of selection in speciation (Coyne...
