How to pronounce“gadusol”in English

Researchers are looking at ways to make gadusol in the lab, and they’ve already had some success with genetically engineering yeast to produce it.

And researchers think those animals got the ability to make gadusol around 500 million years ago, from algae.

Two decades later biologists found a similar compound, called gadusol, in fish and their eggs.

But the darkness also meant mammals lost some features that weren’t so necessary for survival like being able to make gadusol.

But then, in 2015, researchers found that zebrafish could make gadusol and figured out which genes were responsible for making it.

A random mutation probably sprung up in the DNA of a few of these very early mammals, changing their genome so it no longer coded for making gadusol.

It’s the same deal with the West African coelacanth, one of the few non-mammalian vertebrates that doesn’t have the gadusol gene.
