Lagomorpha (Lagomorphs)

The lagomorphs are the members of the taxonomic order Lagomorpha, of which there are two living families: the Leporidae (hares and rabbits) and the Ochotonidae(pikas). The name of the order is derived from the Ancient Greek lagos (λαγώς, "hare") +morphē (μορφή, "form"). There are about eighty-seven species of lagomorph, including about twenty-nine species of pika, twenty-eight species of rabbit and cottontail, and thirty species of hare.
Lagomorphs share a common ancestor with rodents, together forming the clade Glires (Latin: “dormice”). Like the ancestors of most modern mammalian groups, this most recent common ancestor lived after the last great extinction event, the one 66 million years ago that drove all dinosaurs extinct except for birds. Early lagomorphs arose perhaps in Asia and spread across the northern hemisphere. Later, rodents came to dominate more environmental niches, and lagomorphs seem to have been in decline.
