Kronforst said that the butterflies in Ecuador were diverging into two groups because each subgroup was evolving to look more like a different species of poisonous butterfly, which conferred an advantage since predators learned more quickly to avoid them.
The researchers undertook additional genomics lab work and research into related studies to prove that the population in Ecuador had not yet diverged into two separate species, setting it apart from around 20 other systems that had been studied in the past.
