This $747,521 project grant from the National Science Foundation Division of Integrative Organismal Systems supports collaborative research titled "The Intersection Between Cell Fate Decisions and Phenotypic Diversification in a Rapidly Radiating Butterfly Lineage." The grant funds research through July 2025 aimed at increasing scientific knowledge and understanding of major biological problems as part of the Biological Sciences program (CFDA 47.074). The Smithsonian Institution Office of Sponsored Projects serves as awardee to receive funding on behalf of sub-awardee, the Government of the United States. This award facilitates research collaborations examining the relationship between cell differentiation processes and phenotypic variations within a group of butterflies that underwent rapid speciation, with the goal of advancing core biological sciences objectives around major life science questions.
