Robots can surpass the limitations on how high and far animals can jump, but their success only underscores nature’s ingenuity in making the most of what’s available.

By studying how electric organs arose in different lineages of fish, scientists gain new insights into a long-standing question of evolutionary biology.

A statistical analysis of chemical tags on DNA may help unify disparate theories of aging.

Partnerships between engineers and biologists have begun to reveal how birds evolved their superb maneuverability.

The lush biodiversity of the Amazon may be due in part to the dynamics of branching rivers, which serve as invisible fences that continuously barricade and merge bird populations.

Some animal neuropeptides have been around longer than nervous systems.

The optical properties of mitochondrial bundles in the retina may improve how efficiently the eye captures light.

Large blocks of genes conserved through hundreds of millions of years of evolution hint at how the first animal chromosomes came to be.

New studies reveal the ancient, shared genetic “grammar” underpinning the diverse evolution of fish fins and tetrapod limbs.
