Paleontology and Evolutionary Biology The Revitalized Partnership

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 inaccessible to, and unpredictable from, short-term, localized observations. These larger-scale phenomena range from evolutionary stasis at the species level and the mosaic assembly of complex morphologies in ancestral forms to the non-random temporal and spatial distribution of the origin of major evolutionary novelties and clades. Extinction, particularly clade-specific extinction, is the Achilles' heel of many neontological approaches to reconstructing evolutionary processes, from diversity-dependence of evolutionary dynamics to the assembly and consequences of key innovations. Paleontological data both fill these gaps and drive novel research programs on evolutionary processes across scales and hierarchical levels, and the increasing interchange between paleontology and evolutionary biology promises to illuminate many issues neither field could address adequately on its own. • http://darwin-chicago.uchicago.edu/ • ➡ Subscribe: http://bit.ly/UCHICAGOytSubscribe • About #UChicago: • Since its founding in 1890, the University of Chicago has been a destination for rigorous inquiry and field-defining research.
