What is the genetic, cellular, developmental, and evolutionary basis of phenotypic diversity? This question can be addressed from many perspectives— molecular geneticists, developmental biologists, population geneticists and ecologists have typically tackled these problems using very different approaches. However, as phenotype construction has multiple causes, a satisfying understanding of phenotypic diversity ultimately requires the integration of multiple points of view. I am currently using the nematode Caenorhabditis inopinata to connect functional genetics with evolution and ecology to understand the causes of phenotypic diversity. C. inopinata can grow to be nearly twice as long as its close relatives, which include the highly-studied model organism, C. elegans. Furthermore, it thrives in the fresh figs and is associated with its pollinating wasps; figs and fig wasps together represent a classic system in evolution and ecology. C. inopinata is then well-positioned to connect multiple disciplines that aim to understand the bases of phenotypic variation. To this end, I am harnessing genomic, evolutionary, and developmental genetic approaches to address these questions using this system.
