The three-toed skink can give birth to live young and lay eggs in the same pregnancy. What can this little critter teach us about the evolution of live birth?
The Victorian grassland earless dragon may well be the first lizard species driven to extinction on Australia’s mainland. But conservationists aren’t ready to declare it dead just yet.
The evolution of live birth from egg-laying is no mean feat. Now new research reports on the first known example where both eggs and a live birth come from the same lizard pregnancy.
In the wake of two hurricanes in the Turks and Caicos Islands, researchers document for the first time that catastrophic storms can be agents of natural selection, influencing how species evolve.
A new study of an ancient fossil has found it to be the earliest lizard known, so far. It shows they survived one the greatest mass extinctions on Earth.
Reptiles add socioeconomic value but when it comes to accessing detailed reference information about them, students and naturalists can face serious challenges.
Biologists have a centuries-old tradition of publishing on rare and endangered species. But poachers are using open-access information to target valuable and fragile new species.
Mammals’ ancestors had a third eye and the fossil record of its disappearance tells us the story of the evolution of one of our most important features: warm blood.
One of the enduring controversies in evolution is why snakes evolved their long, limbless bodies. A new study suggests snakes may have lost their legs at sea, before crawling ashore.
