You’d think that penguins would love the meaty taste of fish, but it turns out that they may not be able to taste their food much at all. A new genetic study out of the University of Michigan finds that penguins appear to have long ago lost the ability to taste sweet and bitter flavors, as well as the savory, meaty flavor known as umami. Together, sweet, bitter, and umami make up three of the five basic tastes. The other two, sour and salty, may still be present in penguins. The findings are being published today in Current Biology.
