Glires are a class of mammals with rootless incisors that grow throughout their lives. These mammals are thought to have grown from Eutherian and are composed of rodents and lagomorphs. Like other insectivorous, Glires walk on fours and can be fast-moving with an excellent sense of hearing and smell. Most of these animals are herbivorous while others like rodents can be scavengers. They inhabit many terrestrial environments with the hares living in bushes or forests while their cousins the rabbit being domesticated. These animals like Eulipotyphla live in solitary, have claws, and strong limbs for digging tunnels and bodies covered in fur.

When did lagomorphs and rodents diverge?

It is believed that Lagomorphs and rodents diverged about 64.5 million years ago. Lagomorphs and rodents diverged at the start of the Tertiary time period and at the end of the Cretaceous time period. Their divergence happened as a response reaction to global environmental change.

Do rabbits and rodents have a common ancestor?

It is believed that rabbits and rodents have a common ancestor which is why they share similar characteristics and physical traits. Some of those similar traits have been lost in some lineages while they have been retained within others. Although they do share a common ancestor it is not known who the common ancestor was.

Is a rabbit a rodent?

The rabbit is not a rodent and is not part of the Rodentia group of mammals, although they are often confused. Rabbits are differentiated from rodents by their extra pair of incisors directly located one behind the other as well as other skeletal features. Rabbits and hares are part of the group Lagomorpha.

North American Beaver
Dimensioned size comparison illustration of the North American Beaver compared to an average person

Scientifically known as Castor canadensis and known best for its dam building, the North American Beaver is a semi-aquatic rodent physically distinguished by its broad, flat tail. It is identified as the largest rodent in North America and the second largest in the world just behind the capybara.

The purpose of dam building is to create a deep pond in which the beaver can establish its home. The dam is constructed across streams and consists of a pile of sticks with underwater entrances as the beaver is a skillful swimmer. The home or burrow is then made out of sticks and twigs as well.

North American Beavers have a height of 14.2”-16.9” (36-43 cm), body length between 29”-35” (74-89 cm), and an overall weight in the range of 25-75 lb (11.3-34 kg). The tail length of a North American Beaver is 7.9”-13.8” (20-35 cm). North American Beavers have a typical lifespan of 10-15 years in the wild and up to 15-25 years in captivity.

California Ground Squirrel

The California Ground Squirrel (Otospermophilus beecheyi) is a species of medium-sized Ground Squirrel rodent that lives on the ground rather than up in the trees. Scientifically known as Marmotini, ground squirrels are noted for their ability to stand up and remain standing on its hind legs for long periods of time.

Physically, it has a bushy tail, rounded ears, strong claws, and fur that varies in color from tawny to dark, reddish-brown. The ground squirrel is an omnivore that is active during the day, retreating to burrows it digs for safety and rest.

California Ground Squirrels have a height of 7”-8.7” (18-22 cm), body length between 15.7”-20” (40-51 cm), and an overall weight in the range of .6-1.6 lb (280-740 g). The tail length of a California Ground Squirrel is 5”-7” (13-18 cm). California Ground Squirrels have a typical lifespan of 3-6 years in the wild and up to 10 years in captivity.

Pikas can meet their water demands from their food alone, but they do drink water if it is available. Pikas do not hibernate, are diurnal, and typically breed twice a year.

American Pikas have a shoulder height of 4.25”-4.75” (10.8-12 cm), body length between 6”-9” (15-23 cm), and an overall weight in the range of .25-.45 lb (125-200 g).
