The Howard Hughes Medical Institute (HHMI) produces a range of free resources for science education as part of its BioInteractive series. This recent addition is called The Origin of Species and it deals with two primary questions: How do new species form? and Why are there so many species? On this site, visitors can look over three excellent short films that address these matters. The first is a 30 minute exploration into the epic voyages of Charles Darwin and his initial period of discovery and revelation. The second film, "The Beak of the Finch,” looks at four decades of research on finch species that live only on the Galapagos Islands. The final work looks at the ways lizards have adapted to several common habitats with rather interesting results.
