The most controversial feature of the New Zealand flora is the plethora of small-leaved trees and shrubs with wiry interlaced branches. Can a synthesis of competing explanations solve this mystery?
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.
Hopefully, the pepperoni won’t get too jealous over its disc-shaped competitor’s moment in the sun.

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

The discovery of a fossil over 500 million years old reveals new information. Its brain and nervous system are remarkably preserved, filling in some gaps in what we know about arthropod evolution.
A great hammerhead shark’s two eyes can be 3 feet apart on opposite sides of its skull.

The first hammerhead shark was likely the result of a genetic deformity. A biologist explains how shark DNA reveals hammerheads’ history.
Tritylodon, a therapsid, reconstructed as a night dwelling warm blooded animal. Note the steam coming out of its lungs.

Warm-bloodedness is the key to what makes mammals what they are today. That’s why working out when it emerged in mammal ancestors matters.

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.
In Canada, purple loosestrife is an invasive species.

Evolution by natural selection is a potent agent of change, allowing species to adapt to new and changing environments. But is it sustainable?
New research has compared the brains of chimps and macaques with those of humans.

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.
