Additionally, the researchers found differences in feather structure between ancient and extant penguins; differences that may offer clues for how modern penguin feathers evolved.At Punctuated Equilibrium.
Next month our host is This Scientific Life, and you can submit one (good) or two (better) posts about evolution here. Go on, don't be shy now.
