Some forms of camouflage have evolved in animals to exploit a loophole in the way predators perceive their symmetrical markings. New research describes how animals have evolved to mitigate this ...

Researchers have opened a window on another piece of evolutionary biology. They have found that Hox genes, which are key regulators of the way the bodies of bilaterally symmetrical animals form, also ...

The outside shape of mammals is symmetrical: limbs, eyes, ears and nostrils arranged on either side of a central axis. The outside shape of mammals is symmetrical: limbs, eyes, ears and nostrils ...

Starfishlike brittle stars have five thin arms and no central brain, but even so, they move in a carefully coordinated fashion similar to four-limbed animals (including humans). A new analysis delves ...

Many animals naturally develop asymmetric body parts; just look at the massive claw of the fiddler crab or the distorted Picasso-like face of the flatfish. But most mismatches are subtler. As a ...

A new study is the latest in the long-running dispute over which lineage—sponges or comb jellies—is the ancestor to all animals Evolutionary biologists have battled for years over which animal lineage ...
