Neanderthal populations suffered a single late genetic bottleneck, refuting long-held theories about their diversity.

Knowledge of the anatomy and physiology of the semicircular canals and their ... The faces of the horizontal canals are arranged differently, however, with the same concept. A partial diagram of the ...

A study published in Nature Communications describes evolutionary changes in Neanderthal morphology through the analysis of their inner ear structures, known as the bony labyrinth. The research ...

and Mercedes Conde-Valverde from the Cátedra de Otoacústica Evolutiva de HM Hospitales y la Universidad de Alcalá led a team of researchers who analyzed the semicircular canals — the fluid-filled ...

It is widely accepted that results obtained from studying the morphological diversity of the semicircular canals are comparable to those obtained through DNA comparisons. The study focused on two ...

analyzed the morphology of the inner ear of these hominins. Specifically, they focused on the structure of the semicircular canals, which play a crucial role in balance and can reflect the ...

People usually discover they have it in their 40s. The canal that sits highest in your ear, the superior semicircular canal, is covered by bone. When you have SSCD, this bone has a hole or very ...

The semicircular canals are three tiny tubes located in the inner ear. Their primary job is to regulate balance and sense head position. The three semicircular canals—the anterior, lateral, and ...

The inner ear is crucial for maintaining balance and a steady head posture. It consists of three semicircular canals containing fluid and sensory hair cells that pick up motion in the head.

In contrast, the researchers in this study used a novel approach that focused on studying the inner ear. "The semicircular canals, located in the skull between our brain and the external ear ...

Unfortunately, the skulls have become damaged over time and previous work on them revealed that the crucial and delicate semicircular canals in the inner ear were not well preserved.
