The Evolutionary Origins of Biological Diversity

Theodosius Dobzhansky famously wrote that “nothing in biology makes sense except in the light of evolution”. This is especially true for understanding biological diversity: research in the Centre for Biological Diversity focuses on how diversity is generated, and the evolutionary forces that maintain or erode it. The Centre for Biological Diversity has world-leading research programmes in the study of population diversification and speciation, which is the ultimate origin of biodiversity at the level of the species and above.
