Evolutionary developmental biology now permits a richer synthesis. But no similar synthesis has occured for cultural evolution, where institutional, technological, and individual development are crucial. Earlier acquired forms tune receptivity, transform-ation, and transmission of later ideas and practices for individuals, deeply...

The tree of life can be a tool of discovery. Armed with a knowledge of the relationships of different taxa and their distribution in the stratigraphic column, we can make predictions about the kinds of creatures yet to be discovered in the fossil record. Often these tools can be used to recover creatures with features that are...

Darwin's gradualism required that the fossil record's imperfections be emphasized in the Origin, but paleontological data are robust for many questions, and can provide crucial insights into many large-scale evolutionary questions. Enlarged temporal and spatial scales reveal evolutionary patterns and processes that are virtually...

In 2004, Allen Orr and I summarized the history of work on speciation and what it told us about nature. The ensuing five years has seen a flurry of work on the topic, encompassing molecular biology, natural history, genetic analysis, and even philosophy. This talk updates what I see as the important -- and tractable -- questions...
