Learn how an ancient fish gene was repurposed to shape the anatomy of human hands.

Research on fossilized fish from the late Devonian period, roughly 375 million years ago, details the evolution of fins as they began to transition into limbs fit for walking on land. Much of the ...

Limbs can be incredibly useful. Whether it’s the wing of a bat, the elongated leg of a hopping frog or our own grasping arms, limbs have been adapted to all sorts of ecosystems and functions through ...

The paddlefish is a surreal giant, with a spatula-shaped nose that some scientists believe it uses to sense the electric fields of its prey, which it sucks up like a whale. You might not think of it ...

An ancient relationship between fins and fingers has been discovered by palaeontologists. The experts claim to have unravelled the evolutionary changes needed for ancient lobe-finned fish to turn ...

Many fish species evolved parts of their fins into sharp, spiny, needle-like elements -- called fin spines -- that function to protect the fish against predators. Such spines have evolved ...

Segmented hinges in the long, thin bones of fish fins are critical to the incredible mechanical properties of fins, and this design could inspire improved underwater propulsion systems, new robotic ...
