Mammal evolution has been flipped on its head, according to new research that suggests marsupials are the more evolved mammals. By estimating how the common ancestor of mammals reproduced and ...

Around 100 million years ago, a remarkable evolutionary shift allowed placental mammals to diversify and conquer many cold regions of our planet. New research from Stockholm University shows that the ...

Hidden beneath the dunes, a mysterious creature glides through the sand. This is not one of the giant worms of Arrakis in Frank Herbert’s sci-fi epic, Dune. Rather, it’s an enigmatic and tiny mammal ...

Once thought as the least evolved of the mammals that roam our world, new research shows that marsupial evolution might actually be further along than even humans. This old bias towards the creatures ...

Scientists have mapped the genetic composition of a marsupial mammal, the South American gray, short-tailed opossum, gaining insight into the role of "junk DNA" in human evolution and into immune ...

Sequencing of the koala genome has revealed some interesting qualities about these marsupials on their sense of taste. They have more bitter taste receptor genes than any other Australian marsupial, ...

A small golden animal with shovel-like claws swims through the red sand of Australia's central desert in pursuit of its supper. Over millions of years, it's lost its eyes, but it is still a fierce ...
