Butterfly species evolution in action

The video discusses the process of speciation, where one species evolves into two distinct ones. It highlights a study on heliconius butterflies in Ecuador, which are found in two colors, white and yellow. The study compares these butterflies to those in Costa Rica, where the colors represent different species. Experiments showed that yellow males prefer yellow females, suggesting a potential speciation event. Genetic analysis confirmed the population is still mixed. The study provides insights into the early stages of speciation, showing the connection between genetics, morphology, and behavior.
