Evolution and ecology in modular organisms

Scott Lidgard, Assoc. Curator and Section Head, Integrative Research Center

Bryozoan zooidmodules interact with other units and are integrated both within themselves and in an inclusive whole. They originate from budding loci and differentiate as populations of cells. However, they are also inclusive of another level of modularity, in that organs differentiate as entities or parts of the zooids. Both levels of modularity can be individuated using key criteria of evolutionary developmental biology.

Earth Sciences at The Field Museum are focused on paleontology, systematics, evolutionary theory and meteoritics. Most of our paleontologists take an interdisciplinary approach in their research programs, combining fossil and living organisms together to extract information of broad evolutionary significance. Current research within the Robert A. Pritzker Center for Meteoritics and Polar Studies is on presolar grains to afford insights into our parent stars and the history of our Galaxy.
