MISSION 4 — Kangas, Gliders, and Snakes, Oh My!
When a single species diversifies and forms many different but closely related species, the process is called adaptive radiation. Galápagos finches are the result of adaptive radiation. Adaptive radiations occur as species adapt to slightly different environmental conditions. But what about the reverse, or when very distantly related species come to look similar because they live in similar environments? That is call convergent evolution and it’s the topic of this level.
13. Click on the button below to complete a character matrix for all the species in this level. Place an "x" if the species has the trait and leave it blank if it does not. In the final column, use the species tabs to write the location of the species. Some have already been filled in for you.
