Swipe left or right on each dancing peacock spider to create spiders with specific traits. The peacock spiders vary in three traits: tail size, tail colour, and dance speed. As you explore each trait, you’ll learn about correlated selection and how the value of a trait changes the relative effect of selection, and why populations vary in phenotypes. The intuitive interface allows you to quickly grasp science concepts and test different ideas on how selection functions.
