Introduction - Avida-ED and Digital Evolution

Avida-ED is adapted from Avida, a software platform created by a group of computer scientists and software engineers interested in the experimental study of digital organisms in order to better understand how biological evolution works. Both programs provide an instance of evolution in a model environment. The evolution itself is real; the digital organisms are subject to the same processes as biological organisms, such as mutation, replication, and selection. Scientists can study how digital organisms evolve, and examine questions related to the evolution of complex features, sex, intelligence, cooperation, and foraging behavior. Avida has even been used to confirm the outcomes of ongoing biological experiments. This is possible because the process of evolution is "substrate neutral", meaning that when a system possesses three key characteristics - variation, inheritance, and selection - evolution will inevitably result.

Using this powerful tool, you will be able to design and perform your own experiments to test hypotheses about evolution in much the same way that researchers use Avida.

Driving Questions

- What is Avida-ED (how does it work)?

- What do biologists mean when they say the word "evolution"?

- Can we observe evolution? How?

- Can we study evolution by doing experiments? What kinds?

- How is Avida a useful tool for biologists? What are the strengths and limitations of such an approach?
