A Carnegie Evening Lecture

Eggs are uniquely important animal cells. Only eggs can support the development of progeny, returning the cycle of life to its starting point. During Dr. Spradling’s career, study of the fruit fly (Drosophila) egg and how it is formed in the ovary has uncovered some of the molecular processes that propagate life between generations. Comparison to the mouse ovary has revealed amazing similarities between egg production in insects and mammals. Together, these findings teach profound lessons on the evolution of animals, and on the optimum strategy for biomedical research.
