Notes on Sewall Wright: the Adaptive Landscape: My series of posts on the work of Sewall Wright is now approaching its (anti?)climax. The next post, on the shifting balance theory, should be the last.

Models of adaptive radiation were originally developed to explain the early, rapid appearance of distinct modes of life within diversifying clades. Phylogenetic tests of this hypothesis have yielded ...

The adaptive landscape shows how changing physical features, such as jaw shape, are related to survival. Chris Martin has bred more than 3,000 hybrid fish in his time as a graduate student in ...

When biologists think about the evolution of life, they think about climbing mountains. To understand their alpine frame of mind, imagine a biologist studying the fish in a lake. Each fish may be born ...
