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 ...

Mammals with pouches, like kangaroos and koalas, have a radical evolutionary history that suggests they are "more evolved" than previously thought, a new study finds. Marsupials used to be considered ...

Shoot for the moon. Even if you miss, you'll land on the next tree. Many groups of mammals seem to have taken this evolutionary advice to heart. According to our newly published paper in Science ...

Behavioral Ecology and Sociobiology, Vol. 68, No. 7 (July 2014), pp. 1085-1096 (12 pages) Offspring sex ratios in mammals vary in potentially adaptive yet unpredictable ways. An integrative approach ...

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 ...

Humans aren't the only creatures that prefer to use one hand over the other. Now, a new study finds that marsupials that run about on all fours have paw preferences, too. In particular, sugar gliders ...

Kangaroos, koalas and other marsupials are even weirder than we give them credit for. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Mammals ...
