Are Rats and Guinea Pigs Related?
WouterAlthough they look similar, rats and guinea pigs are very different animals. The differences are primarily related to the diets of these two animals. Rats are omnivores, while guinea pigs are herbivores. Both species need large amounts of room to move around and exercise. They also need to be kept in separate cages.
Guinea pigs are more nervous than rats. They freeze when they’re scared, and they may nip at someone who’s not used to handling them. They also need fresh bedding and outdoor space to play in. You should change their bedding once a week.
Despite their similar personalities and cuddliness, rats and guinea pigs aren’t compatible companions. While their small size and cuddly features may make them a great companion for a family, their different personalities make them unsuitable for a friendship.
In a recent study, researchers discovered that the guinea pig’s genetic sequences are different from those of rats and mice. This suggests that they are on a separate evolutionary branch. However, other scientists have criticized this finding. German molecular biologist Juergen Brosius believes that DNA tests are not reliable enough to rebut anatomical evidence.
The study used nine adult laboratory specimens to study the anatomy of the two species. They were size-matched for comparison purposes and weighed between 350-400 grams. The animals were housed in the University of Manchester’s Biological Services Facility. All work was conducted in accordance with UK Home Office guidelines, and local ethics committees approved the study.
