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

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

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 ...

Irf3 and Irf7 initiate the expression of type 1 interferons that further exacerbates the antiviral innate immune response to infection. Table 2 Table of antiviral genes studied in zebrafish models of ...

This study provides a valuable new resource to investigate the molecular basis of the particular features characterizing the pipefish embryo. The authors found both unique and shared gene expression ...

Elastic cartilage doesn't preserve well in fossils ... Crump and his colleagues inserted human outer ear enhancers into zebrafish genomes. The experiment triggered activity in the gills of ...

“So it wasn’t really known if fish had elastic cartilage or not. It turns out that they do.” Human outer ear enhancer driving green fluorescence protein expression in the gills of a 2-week-old ...
