Evolutionary Arms Race

An evolutionary arms race is a situation involving organisms evolving in response to each other. This simulation uses a scenario in which a predator has resistance to a toxin produced by its prey. The prey species produces the toxin in such concentration that it is deadly to all animals other than the one resistant predator. Check out the arms race blog post to get more information about the simulation and the real-world example on which it is based. Click here for a virtual lab to use with this simulation.

Part I of this virtual lab examines the effect of increasing amounts of toxin on predator speed. Part II examines how dependence on the toxic prey species for food affects the predator species's resistance. Click the "Introduction" button to get more information about the specific simulations.
