Scientists have traced the evolutionary origin of humans' outer ears to the gills of ancient fish through a series of ...

The genes that build the cartilage of fish gills were repurposed to build the cartilage in mammals’ outer ears ...

Two new studies offer insights into the evolution and development of external ears, which appear in humans and other mammals ...

This suggests that the outer ear evolved from cartilaginous gills, with the first elastic cartilage possibly arising in ancient marine invertebrates. This summary was automatically generated using ...

The scientists were able to incorporate enhancers that help form the elastic cartilage of the human outer ear into the genomes of zebrafish . Remarkably, the human outer ear enhancers were active ...

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 ...
