About This Image

Toothed, but enamelless, and toothed mammals.

Mammal tooth structure varies from toothed, to toothed but enamelless, to toothless, of which the skulls of two are shown here (top: a toothed but enamelless Choloepus hoffmanni, the two-toed sloth; bottom: a toothed Sus scrofa, the wild pig—the top image is 1/5 the scale of the bottom image). A Research Article in this issue of PLoS Genetics (see Meredith et al., 10.1371/journal.pgen.1000634) synthesizes paleontological data using ages of fossils and molecular data on the enamelin gene (ENAM) to decipher the evolutionary transitions of teeth in mammals. Just as teeth decay during life, so do the molecular sequences of ENAM over evolutionary time. Rob DeSalle offers an accompanying Perspective.
