Summary: A lizard lineage which has evolved over the last 19 million years has helped scientists to re-think one of the most important concepts of modern biology: adaptive radiation.'Adaptive radiation' is recognised as a pillar of evolutionary science. It describes the development of new biodiversity, and is triggered when a species encounters a new environment with plenty of available resources -- this is called 'ecological opportunity'. This single species then makes the most of these resources and multiplies rapidly into several new forms. When all these resources have been used up by new species, the process of biodiversity proliferation slows down dramatically.
