The lizard and the egg: Liolaemus lizards break golden rule of biology

Researchers at ANU have made a remarkable discovery about a group of lizards, and how they’ve managed to thrive in extreme conditions on one of the world’s highest mountain ranges.

The Liolaemus lizards – found mainly around South America’s Andes Mountains - reproduce in a way that challenges one of biology’s best known rules, Dollo’s Law.

PhD candidate Damien Esquerre says as the Andes formed, the lizards evolved to give birth to live young, because eggs struggle to incubate in cold temperatures.
