Climate change could see dozens of lizard species becoming extinct within the next 50 years, according to new research published today. The often one-directional evolutionary adaptation of certain lizard species' reproductive modes could see multiple extinctions as the global temperature increases.

Globally it has been observed that lizards with viviparous reproduction (retention of embryos within the mother's body) are being threatened by changing weather patterns. A new study suggests that the evolution of this mode of reproduction, which is thought to be a key successful adaptation, could, in fact, be the species' downfall under global warming.

Dr Daniel Pincheira-Donoso, from the School of Life Sciences at the University of Lincoln (UK), is the lead author of the paper detailing these amazing predictions, published today in the scientific journal Global Ecology and Biogeography.
