About this app
In Cha Cha Island, you're a musical creature looking for a mate. Dance and sing your way into their heart while keeping time and showing off your different instruments and dance moves. In this rhythm game, players will learn about how mate preferences can shape the evolution of traits. While playing, players help collect data to demonstrate how evolution by sexual selection works.
