Researchers used powerful technology to analyse thousands of individual cells at once, considering which genes are active.

How this mammalian face evolved has long been an overlooked mystery. In recent years, researchers have tackled this problem using mice, a key model in biomedical research. However, despite their ...

Because some of the ear’s structure involves bones, much of the evolution of the ear can be followed through the fossil record. The evolution of the mammalian ear is well documented and makes a nice ...

Human outer ears may have evolved from the cartilage in ancient fish gills, according to recent research. Gene-editing experiments demonstrated a genetic link between fish gills and mammalian ears ...

The story of how we developed our ability to hear is one of the great examples of evolution in action. Because the first animals to crawl out of the water onto the land would have had great ...
