Serotine bats have penises seven times longer and wider than their female counterparts' vaginas
This 'shrew-like' animal is surprisingly old.
To be honest it probably ran away from them, not with them.
The ancient mammal "bends and even breaks a lot of rules," said researchers.
One of the world's most unique mammals is heading for extinction.
The differences are too many to say all at once.
Although this mammalian forerunner still reproduced like a reptile, the fossils shed much light on our own evolution.
Talk about a groundbreaking discovery.
Eons ago, many millennia before written history, bizarre animals roamed the Earth.
In a way, we're all the descendants of these rats.
They may be the cutest animal in the country, but we're cooking the d'awww out of them.
Great Barrier Reef's only endemic mammal, the Bramble Cay melomys, is now officially extinct, scientists say.
Three different ways to breathe: Mammals, birds and insects breathe in different ways, as exemplified above. Humans, as mammals, inhale by moving the diaphragm to lower the air pressure in the chest cavity and pull air into the lungs. The human chest cavity is always at a lower pressure than the outside environment. Birds on […]
The flying lemur is the most accomplished mammalian glider.
Although mammals surfaced only 20 million years after the first dinosaurs evolved, there's a general consensus that mammals were shadowed and reclusive in the face of dinosaurs, seeing how they were the dominant animals on the planet back then. As such, early mammals are thought to have been mostly nocturnal with minimal interaction with dinosaur environments, occupying very limited ecological niches. This conventional thinking might be toppled by recent findings made by Chinese paleontologists who discovered two highly sophisticated early mammals each at least 160 million years old: the first tree-clinging mammal and the first burrowing mammal. These creatures munched on the same plants dinosaurs did, proving they seemingly coexisted in the same ecological framework.
A fossil of a small, forest-floor-dwelling animal called Megaconus puts a big question mark on the evolution of mammals – it suggests that its group predated animals, while another one, from its tree dwelling ‘cousing’ Arboroharamiya shows the group belonged to the mammals. The two fossils have paleontologists scratching their heads, not knowing where to […]
An extremely challenging study published by a team of researchers from the Stanford School of Medicine claims that through some unknown mechanism mammals can bias the sex of their offspring in order to win the genetic lottery and produce extra grandchildren. The holy graal of modern evolutionary biology After analyzing 90 years of breeding records […]
For the past twenty years there’s been a debate whether the mammal explosion that eventually made the class of animals dominant on Earth happened before or after the end of the dinosaur reign. Scientific papers and various evidence supporting both views have surfaced along the years, but a recent massive study conducted by a collaborative […]
Well it may be a bit of overreaction, but with the Halloween and all, you just have to call it: 70 million year old mammal had long, oversized, blood-red teeth, scurrying at the feet of dinosaurs. The discovery of a new skull now gives new insight into his diet and habits. Barbatodon transylvanicus lived in […]
The previous 5 mass extinctions wiped out more than three quarters of the world’s animals, and if things continue to move in the same way, the same thing will happen in North America, according to a University of California, Berkeley, and Pennsylvania State University analysis. Numerous scientists have warned that the direction things are moving […]
Blue whales are not only the biggest living creatures in the world right now, but the biggest ever to have ‘walked’ the face of the earth; they’re also the loudest for that matter. After recovering from near extinction in the beginning of the 20th century, blue whales are finally getting a part of the respect […]
