LINCOLN, England, March 6 (UPI) -- Global warming could lead to extinction within 50 years of lizard species whose embryos are retained with their mothers' bodies, British researchers say. Dozens of ...

May 9 (UPI) --As the planet heats up, microbes inside the guts of lizards are being killed off. In a series of lab tests, researchers at the universities of Exeter and Toulouse found rising ...

Dozens of lizards that evolved the ability to give birth to live young in order to carve a niche for themselves in colder climates may become extinct as the planet warms over the next 50 years, ...

Climate change could see dozens of lizard species becoming extinct within the next 50 years, according to new research. The often one-directional evolutionary adaptation of certain lizard species' ...
