Evolution In Action

Biologist Larry Gilbert studies Heliconius butterflies at the University of Texas, focusing on their diverse color patterns and potential role in speciation. Supported by the National Science Foundation, Gilbert's team observes a possible evolutionary split in Ecuador, where color preference may lead to new species. They compare these findings with Costa Rican butterflies, where color differences already define separate species. The research aims to identify genes responsible for these traits, offering insights into evolution.
