Is 'natural selection' inimical to bio-diversity? Why is the natural world not dominated by a few 'super' species? And in the future, can the richness of nature be preserved? In this album, Jonathan Silvertown, Professor of Ecology at The Open University, explains how Darwinian theory uses the concept of niche specialisation to account for the diversity of flora and fauna on Earth. If it were not for environmental niches, Darwinian 'demons', might emerge, powerful species whose evolutionary fitness makes them all conquering. However, according to Darwin, the natural world is infinitely complex and inhabited by a multitude of different species, each of which is peculiarly adapted to its local environment.
