Holding on in hurricane-force winds.
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.
New research shows green-blooded skinks have evolved multiple times, which could help lead to explanation as to why.
Bipedal movement has existed in modern reptiles for much longer than we previously knew.
The Black Mamba is a is a venomous snake endemic to parts of sub-Saharan Africa.
Reptiles add socioeconomic value but when it comes to accessing detailed reference information about them, students and naturalists can face serious challenges.
Echis, also known as the saw-scaled viper, dominates snakebite statistics and kills more people annually than any other.
Indian-made antivenoms, common throughout Africa because they are affordable, showed little-to-no neutralisation of the African Echis venoms.
Venom from lizards such as the Komodo dragon has the potential to treat heart attacks, strokes and blood clots.
A group of lizards in Brazil have evolved bigger heads in just 15 years thanks to their new environment.
The beautiful Chinese cave gecko, or Goniurosaurus luii, is highly prized by poachers.
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.
There’s a battle for resources going on in there.
Embryos greedily want more resources than their fair share. New research investigates how early in evolution their hormonal tactics arose.

Invasive species colonize and spread widely in places where they are not normally found. Invasives often affect native species by eating them, out-competing them and introducing unfamiliar parasites and…
