The Evolutionary Origin of Periodical Cicadas: A Sci-Fi Story

Periodical cicadas are known for their unique 17- and 13-year life cycles and mass emergence events. This mystery of why they would have evolved these two prime-numbered life cycles has attracted many biologists and mathematicians. Dr. Yoshimura will explore this phenomenon through a science-fiction story of the prime-numbered life cycles in periodical cicadas during the ice ages. In this talk, he will also introduce a new technique of catching cicadas that sing at the tops of trees, for any children with insect collections, as many Japanese children (Dr. Yoshimura very much included) do.

Speaker: Dr. Jin Yoshimura, Shizuoka University
