Research led by the Milner Center for Evolution at the University of Bath looking at the evolution of terrestrial orchid species has found that global cooling of the climate appears to be the major driving factor in their diversity. The results help scientists understand the role of global climate on diversity of species, and how our current changing global climate might affect biodiversity in the future.
