Abstract
In medical laboratory animals, the pig is the closest species to human in evolution, except for primates. As an animal model, the pig is highly concerned by many scientists, including comparative biology, developmental biology, medical genetics. Rodents as animal model for human hearing defects has are poor producibility and reliability, due to differences in anatomical structure, evolutionary rate and metabolic rate, but these happens to be the advantages of the pig model. In this paper, we will summarize the application of miniature pig in the study of human hereditary deafness.
