Recent research by INHS Ornithologist and Parasitologist Kevin Johnson has found that bird lice have undergone convergent evolution, evolving different body shapes dependent on where they live on the bird. Despite the morphological similarities between lice from the wings of different bird groups, the species are more closely related to other lice species on the same bird group. The same pattern holds true for lice from the head and body. Learn more about Kevin Johnson's research through this video by the U of I News Bureau.
