361: Evolutionarily conserved pathways in yeast and mammals

Thanks to the dubious biologist we learn that Mammals feed off yeast pathway:

The biochemical pathway that senses amino acid deficiencies in yeast is also at work in mammals, researchers report in this week's Science. While this signaling initiates amino acid synthesis in yeast, it alters eating behavior in rats, according to senior author Dorothy Gietzen of the University of California, Davis.
Common descent. Too cool.
