This cartilage eventually became further elaborated to form the prominent outer ears of early mammals. An additional surprise was that the elastic cartilage of gills may have arisen much earlier ...

The key to tracing the origins of humans' outer ears to fish was the discovery that elastic cartilage is also present in fish gills. "When we started the study, there was very little out there ...

This cartilage eventually became further elaborated to form the prominent outer ears of early mammals. An additional surprise was that the elastic cartilage of gills may have arisen much earlier ...

The outer ear is unique to mammals, but its evolutionary origin has remained a mystery. According to a new study published in Nature from the USC Stem Cell lab of Gage Crump, this intricate coil of ...

Longitudinal section of mammal elastic cartilage (Elastic histology stain (ETS), x40, Slide 19-40 D9-IV4b): The matrix of elastic cartilage is reinforced by many elastic fibers (blue-black) and the ...

The species are all modern bony fishes, suggesting that elastic cartilage is a general feature in this group, according to the study, which was published Jan. 9 in the journal Nature.

These are my 5 must-read science books. Our outer ears and those of other mammals are made of a subtype of cartilage called elastic cartilage.
