Lagomorpha is a mammal order. It includes pikas, rabbits and hares. Although the lagomorphs look like rodents, they are not so. They have four incisors on the upper jaw, not two as in 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, hares and rabbits, and Ochotonidae, the pikas.

It has been known for some time that the Lagomorpha is an unusual group, and there have been many speculations about its evolution. Darren Naish explains this.[4]
