Lagomorpha is a mammal order. It includes pikas, rabbits and hares. Although lagomorphs look like rodents, they are not rodents, but are closely related to them. They have four incisors on the upper jaw, not two as with rodents. Also, they only eat plant material, not meat as rodents do to some extent.
Rabbits were classified under rodents until the 20th century.[2][3] They are divided into two families: Leporidae, which are hares and rabbits, and Ochotonidae, the pikas.
It has been known for some time that Lagomorpha is an unusual group, and there have been many guesses about its evolution. Darren Naish explains this.[4]
