Rodents and lagomorphs breed and are born similarly. However, had this question been asked over 100 years ago, the answer would have been ‘yes’. It's easy to think of rabbits as the cuddly cousins of mice and other rodents. Scientists figured that rabbits had evolved in the same way as other rodents (i.e. The reason rabbits are not rodents is because when they are adults, they are far from being able to fit easily in your hands. Rabbits are not rodents. But they're actually not that closely related, despite the fact that a century ago, they were absolutely considered rodents. Because the incisors that are found in both rodents and lagomorphs are constantly growing. No. a common rodent ancestor) and, therefore, rabbits were rodents. As mentioned previously; up until 1912, rabbits were classified as rodents. We now know that this is not the case. But what is the lagomorph group? Rodent.Rodents (from Latin rodere, "to gnaw") are mammals of the order Rodentia, which are characterized by a single pair of continuously growing incisors in each of the upper and lower jaws. They are both placental mammals, meaning that they both have a placenta present during gestation. Ask any rabbit parent, and they will tell you that these animals love to gnaw! Rodents are concidered small and are about the size of your hand. Once upon a time, they were thought to be related. No, rabbits and hares are members of the family Leporidae, one of the two families (the other is the Ochotonidae or pika family) in the order Lagomorpha. Both rodents and rabbits have a indeterminate growth in their incisors. That thought changed. They are from the order lagomorpha. There are seven different genera in the family classified as rabbits, including the European rabbit (Oryctolagus cuniculus), Cottontail rabbit (genus Sylvilagus; 13 species), and the Amami rabbit (Pentalagus furnessi, endangered species on Amami Ōshima, Japan). Rodents are from the order Rodentia. Is a rabbit a rodent? As we have just covered, despite many people’s misconceptions that rabbits are rodents, the answer is actually no, rabbits are not rodents. Why? A group of baby rabbits produced from a single mating is referred to as a litter, and a group of domestic rabbits living together is sometimes called a herd. Their name goes beyond zoological taxonomy, though, and extends into how we think of rabbits. This is often the driving factor in the incessant gnawing, as mice, rabbits, rats, and hares alike have to wear down their teeth. They also have hard enamel on the external surface of the incisors and a soft dentin behind; but the front of rabbit incisors is white and not orange like rodents. Rabbits are small mammals in the family Leporidae of the order Lagomorpha, found in several parts of the world.
