New genes can be formed following gene duplication and editing; an underlying molecular mechanism of evolution
Emergence of a new gene seen for the first time in the lab - life short science news

For the very first time, biotechnologists have witnessed the emergence of a completely new gene.

By forcing the yeast species Saccharomyces pastorianus to eat complex sugars, the cells started to form a new sort of “mouth” by recombining parts of already existing genes into a new gene.

This spectacular observation confirms what biotechnologists had suspected for decades: living things can make new genes by copying and then editing them, which is a driving force of evolution.
