Microevolution of quantitative traits in the wild can be predicted from a knowledge of
selection and genetic parameters. Testing the predictions requires measurement of the …

In 1972 Stephen Jay Gould took the scientific world by storm with his paper on punctuated
equilibrium. Challenging a core assumption of Darwin's theory of evolution, it launched the …

The origin of Australopithecus, the genus widely interpreted as ancestral to Homo, is a
central problem in human evolutionary studies. Australopithecus species differ markedly …

Outline-based morphometric methods have been more or less restricted to the consideration

This new text provides an integrated view of the forces that influence the patterns and rates
of vertebrate evolution from the level of living populations and species to those that resulted …

Nature's discontinuities occur both in the hierarchical structuring of genealogical individuals
and in the distinct processes operating at different scales of time, here called tiers …
