In this project, you will learn about two closely related species of plants.  For over 150 years, scientists thought these were just one species, but their uniqueness was recently confirmed by genetic evidence.  These types of similar-looking-but-distinct plants are called “cryptic species.”

Your mission is to help spot the differences between these two species of plants.
Researchers have developed a computer program to differentiate cryptic species using artificial intelligence. Researchers also hope to learn more about how humans differentiate between species and compare these human tactics to the ones used by the computer.
