In Greek mythology, the chimera combined the physical characteristics of several different creatures to make a wholly new beast with attributes both like and unlike its parents. In two independent adaptive laboratory evolution experiments, a recombination event between two maltose sugar transporter genes from the yeast Saccharomyces eubayanus resulted in a chimeric transporter that gained the ability to carry larger maltotriose sugar molecules. The uptake of maltotriose by S. eubayanus is a critical step in being able to ferment a sugar whose consumption is important for the production of high-quality beer. See Baker, Hittinger.
