Rodents are a diverse group of small mammals belonging to the order Rodentia, which includes mice, rats, squirrels, hamsters, and gerbils, among others. They are characterized by their continuously growing incisors, which they use for gnawing and chewing. Research on rodents is important in various scientific fields, including biology, ecology, and medicine. Rodents are commonly used as model organisms in laboratory research due to their similarities to humans in terms of physiology and genetics. They have been instrumental in studying topics such as genetics, behavior, neuroscience, and disease. Rodents are also important in ecological research, as they play key roles in ecosystems as both prey and predators. They are studied to understand their impact on the environment and how they interact with other species. Overall, research on rodents helps scientists gain insights into various aspects of biology, ecology, and medicine, ultimately contributing to advancements in these fields.
