Invasive species are organisms found outside their native range. When these foreign species are introduced into new ecosystems the results can be dramatic as they displace native species and cause problems that the native system cannot adapt to.

In 1977 Carl Woese of the University of Illinois shook the world of biology and its long established tree of life when he announced the discovery of an entirely new group of organisms – the Archaea. Dismissed by many, further proof was provided when a vent organism (Methanoccus jannaschii) was sequenced.

Today this new phylogeny is the basis for a range of new explorations in microbial biology from the origins of life to its diversity. Developed by Susan Offner and based on the pioneering work of Woese, this kit takes students to the cutting edge of evolution, classification, and beyond.
