Evidence suggests gene moved from herring to smelt in process similar to genetic modification in the lab
Millions of years before scientists created genetically modified Atlantic salmon with genes from two other fish, nature created genetically modified smelt with a gene from herring, growing evidence shows.
And now the Canadian scientists who first proposed that controversial idea say they have a hunch how nature might have done it.
A new study by Queen’s University researchers Laurie Graham and Peter Davies finds “conclusive” evidence for the controversial idea that the antifreeze gene that helps rainbow smelt survive icy coastal waters originally came from herring and was somehow stolen by smelt about 20 million years ago.
