Original U Michigan coverage of the study findings are excerpted here:

“ANN ARBOR—A University of Michigan-led study of penguin genetics has concluded that the flightless aquatic birds lost three of the five basic vertebrate tastes—sweet, bitter and the savory, meaty taste known as umami—more than 20 million years ago and never regained them.

Because penguins are fish eaters, the loss of the umami taste is especially perplexing, said study leader Jianzhi “George” Zhang, a professor in the U-M Department of Ecology and Evolutionary Biology.

“Penguins eat fish, so you would guess that they need the umami receptor genes, but for some reason they don’t have them…”
