A few hundred million years ago, fish fins morphed into the arms and legs of terrestrial animals, according to evolutionary theory. So, you’d think science would know just about everything about them ...

Figure 2: Fin ray bending resulted in increased activity of the pectoral fin nerves. Figure 3: Nerve activity reflected the speed of fin ray deflection in ramp-and-hold stimuli. Figure 5: Spike ...

Although present in more than 6,000 living species of fish, the adipose fin, a small appendage that lies between the dorsal fin and tail, has no clear function and is thought to be vestigial. A new ...

The human fingertip is a finely tuned sensory machine, and even slight touches convey a great deal of information about our physical environment. It turns out, some fish use their pectoral fins in ...

In the deep ocean, where sunlight never reaches, and food drifts down like confetti, survival is less about speed and more ...

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 ...

When tetrapods (four-limbed vertebrates) began to move from water to land roughly 390 million years ago it set in motion the rise of lizards, birds, mammals, and all land animals that exist today, ...

To answer how animals made the transition from sea to land, scientists have traditionally looked to the fossil record. But in the past 30 years, scientists have searched for changes in genes that can ...
