Convergent evolution study sheds light on how new genes arise


Recommended Posts

Where do new genes come from? That's the question a team of biological sciences researchers from the U of A set out to answer in a new study.

They did so by examining the evolution of antifreeze proteins in fish—an essential adaptation that allows fish to survive in freezing waters by preventing ice formation through the binding of their antifreeze proteins to ice crystals.

The team investigated these proteins in three unrelated fish lineages and uncovered surprising results. While the proteins in each lineage are functionally and structurally similar, they evolved independently from different genetic sources.
