Yeast findings link processes in heart disease, cancer | Science Blog:
By studying a little-known yeast too primitive to get diseases, Johns Hopkins researchers have uncovered a surprising link between two processes at play in heart disease and cancer in people. In experiments with yeast known as S. pombe, the researchers discovered that a gene that helps the organism make cholesterol also helps it survive when oxygen is scarce. The finding, described in the March 25 issue of Cell, offers a new strategy for killing infectious yeast, but it also suggests that cells' efforts to make cholesterol and detect oxygen levels might be connected in people, too.
How's that for common descent? We find a link between two processes in yeast, and think that they might be linked in humans. That's common descent, and nothing but.
