摘要
The Red Queen(1) describes a view of nature in which 物種 continually evolve but do not become better adapted. It is one of the more distinctive metaphors of 演化ary biology, but no test of its claim that speciation occurs at a constant rate(2) has ever been made against competing models that can predict virtually identical outcomes, nor has any mechanism been proposed that could cause the constant-rate phenomenon. Here we use 101 phylogenies of animal, plant and fungal taxa to test the constant-rate claim against four competing models. 系統發育 branch lengths record the amount of time or 演化ary change between successive events of speciation. The models predict the distribution of these lengths by specifying how factors combine to bring about speciation, or by describing how rates of speciation var
