Three extinct squirrel-like species discovery supports earlier origin of mammals in late Triassic
Paleontologists have described three new small squirrel-like species that place a poorly understood Mesozoic group of animals firmly in the mammal family tree. The study, led by scientists at the American ...
Study shows rhinoceros beetle horns evolved to accommodate species-specific fighting styles
Nature collides with James Bond: Newly discovered ant species hides in plain sight
Researchers plan and plot every considerable aspect of their work, but sometimes it's something unexpected and seemingly insignificant that leads to the real discovery. That was the case for Scott Powell, ...
Research confirms controversial Darwin theory of 'jump dispersal'
More than one hundred and fifty years ago, Charles Darwin hypothesized that species could cross oceans and other vast distances on vegetation rafts, icebergs, or in the case of plant seeds, in the plumage ...

Colour variability in Crimson Rosellas is linked to a virus
Despite its name, the Crimson Rosella is perhaps Australia's most colour-variable bird and a cause of this striking and beautiful diversity seems to be a disease that's potentially deadly to many other parrots.
Dinosaur family tree gives fresh insight into rapid rise of birds
The most comprehensive family tree of meat-eating dinosaurs ever created is enabling scientists to discover key details of how birds evolved from them.
When David beats Goliath
Body size has long been recognized to play a key role in shaping species interactions, with larger species usually winning conflicts with their smaller counterparts. But Queen's University biologist Paul ...
