Evolutionary biology and the fossil record reveal a great deal about the origins of chickens and eggs.
Being feverish is unpleasant, but it can help your body overcome invading pathogens.

The heat and chills that come with fever are not only uncomfortable but also metabolically costly. Increased body temperature, however, can make all the difference when you’re sick.
There are areas of biology that may be considered optional at younger year levels, such as botany, entomology and marine ecosystems. Evolution is not one of these.
Older monkeys still hang out, just with a smaller circle of intimates.
Many older people tend to trim their social circles and focus their social efforts on family and close friends. New research on our close primate relatives may help explain why.
Human evolution is typically depicted with a progressive whitening of the skin, despite a lack of evidence to support it.

From Aristotle to Darwin, inaccurate and biased narratives in science not only reproduce these biases in future generations but also perpetuate the discrimination they are used to justify.
The battle for power in the animal world isn’t always about brute force.

Life can be a struggle for power – not just for people but for nonhuman animals, too. An animal behaviorist explains how this quest can be more Shakespearean drama than boxing match.
The way human brains develop is special – but not quite as special as you’d like to think, if we consider Neanderthals as well.
There is more to evolution than the genes species inherit.
Tibetan monks at a monastry in Gansu province in China. New research shows sending a child to a monastery can have surprising evolutionary advantages for a family.
Listen to the first episode of Discovery, a new series available via The Conversation Weekly podcast, telling the stories of fascinating new research discoveries from around the world.

Australia has more than 60 species of native rodents found nowhere else in the world. New research used museum specimens to find out how they got here.
Axolotls are a model organism researchers use to study a variety of topics in biology.
Axolotls are amphibians known for their ability to regrow their organs, including their brains. New research clarifies their regeneration process.
The majority of fertilized eggs die and are resorbed into the body.
Human embryos are far more likely to die than come to term, an evolutionary trait seen across species. Laws granting personhood at conception ignore built-in embryo loss, with potentially grave consequences.

Here’s what we can learn from our closest extinct relatives.
Slime plays an essential role in the lives of snails, hagfish and people alike.

A vast array of species, including people, use slime for a variety of essential bodily functions. Studying the genetic ancestry of slime surprisingly showcases the role of repetitive DNA in evolution.

A new theory linking metabolism and size shows how evolution, not physics, is the driving force behind many of life’s patterns.
Dogs use their tails to communicate.

An anthropologist explains some of the many ways animals use their tails, from balancing as they walk to attracting a mate.

Qikiqtania enjoying its fully aquatic, free-swimming lifestyle.
The newly discovered species – Qikiqtania – highlights evolution’s twisty, tangled path.
Frilled sharks haven’t changed for about 80 million years! And while they may look a bit like snakes from a distance, they are actually much more similar to other sharks close up.
Few animals have babies without sex, so biologists assumed asexual reproduction must have evolutionary drawbacks. But a self-cloning Australian grasshopper shows things might be more complicated.
A long-term study of wild animal populations shows each generation is on average almost 20% genetically ‘better’ than their parents at surviving and reproducing.
