In 1981, when the world believed that wild crickets had become extinct, 7 wild crickets were rediscovered in China. Now the number of domestic crickets has reached 1,617. At present, the world's crickets are all bred from 7 of that year. Seriously, Zhu Xi has become the species with the lowest genetic diversity among endangered birds in the world, which will reduce the population's disease resistance and increase the mortality rate, especially its ability to resist deadly diseases such as bird flu is extremely low. From this we can infer:. ['Inbreeding is not conducive to species evolution and will be naturally eliminated.', 'Genetic diversity is critical to the survival and development of Zhu Xi.', "Zhu Xi's population has increased significantly, and its risk of extinction has further reduced.", 'To save Zhu Xi, it is necessary to develop artificial cultivation and breeding technology.']
