Listen up: mammals seem to have evolved the delicate bone structure of the middle ear at least twice. The surprising discovery comes from a fossil, found off the southern coast of Australia, that ...

The ear was not an overnight invention, but the product of an inconceivably long evolutionary tinkering. Source: Jason Downes et al, “The cranial endoskeleton of Tiktaalik roseae .” Nature doi ...

Three Bones in Each Ear The ear contains three small bones: malleus, incus, and stapes. They form a critical sound-transmission system.

The three bones of the middle ear (hammer, anvil, stapes) make up the ossicular chain. This bony chain, which is found in all mammals is dedicated to the transmission of sound waves from the tympanic ...

Tetrapods, for example, are good at hearing airborne sounds, thanks to small bones that can vibrate in their ears. The earliest of those bones to have evolved was the stapes. But the stapes did not ...

On the other hand, animals with three middle ear bones tend to hear at much higher frequencies. For humans, our hearing can extend to 20 kHz, although most of our lives are spent attending to ...

All the latest science news on ear bones from Phys.org. Find the latest news, advancements, and breakthroughs.

The ear bones, located in the inner ear, are similar to tree rings in that each day they form a new layer composed of the different chemicals in the water where they lived.

Bone conduction headphones take advantage of a sound pathway that bypasses both the ear canal and ear drum. They vibrate against your bones—usually those in front of the ear—and send sounds ...

To scientists studying fish, the bones in salmon ears are like a "travel journal," telling of how some species of salmon have adapted to survive.

“Primary” ear and temporal bone meningiomas are tumors that are frequently misdiagnosed and unrecognized, resulting in inappropriate clinical management. To date, a large clinicopathologic ...
