Sea cows (Sirenia) descended from four legged mammals that roamed Africa when this continent was isolated. They belong to the Afrotheria, the 'African beasts'.
Taking the placenta as a case study, researchers are able to piece together how new organs evolve, by repurposing old tissues and using them to do new jobs.
By understanding sleep across animals we can gain insights into improving the quality of human sleep. It can also help to bolster conservation management strategies for the animals in question.
From birds to bees, the wildlife in your backyard can tell us important things about the health of our environment.
There are plenty of mammals that have adapted to life in water, some more than others. That meant they also had to adapt the way they feed.
Large mammals such as elephants and whales are among the most long-lived of animals, but very tall humans don't enjoy the same benefits.
In 1997, scientists announced they'd created a healthy sheep cloned from another ewe's mammary gland cell. Two decades on, the technique is being refined and applied to new challenges.
The notion of using dingoes to protect Australia's wildlife is based on wolves in the US, but research cast doubts on the link.
Good science isn't rooted in chance. It's based on people with expertise being in the right place at the right time, equipped with enough knowledge to know what they're looking at.
It is crucial to integrate paleoclimate data into ecological studies. This will increase understanding of how species respond to climate change.
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.
The perils of bug parenting.
New technology reveals that digging echidnas play a crucial role in Australia's ecosystems.
Half of Tasmania's eastern quolls – Australia's last population – have disappeared in the past 10 years.
Climate change has an impact on small mammals and some battle to survive. But some others have developed intriguing coping mechanisms to survive.
An old technique to explore the inside of fossils unfortunately ended up destroying some unique specimens. New technology has been used to reconstruct one such fossil.
Modern sabre-tooth mammals have their canines constantly on display. This allows them to seduce mates. But was sexual selection also an important phenomenon among our pre-mammalian ancestors?
The Grampians, like much of Australia, has swung from Millennium Drought to Big Wet and back again, putting animal populations on a rollercoaster that could get worse as climate change bites.
African lions were initially thought to belong to a single subspecies but new research shows that there is more diversity on the African continent.
Sloths have been moving slowly for 64m years.
