A very large museum. The plush Kiwi and Moa birds (dinosaur-like birds) record links to Pangu hundreds of millions of years ago, because there were no quadruped mammals on Earth when they separated from Australia and Antarctica, so they lived comfortably on land and slowly degraded the function of wings, but they also brought them when human footprints arrived. With quadruped mammals, their survival began to be threatened. Terrorist birds disappeared in the 15th century. Some of the commentators are modern Maori, enthusiastic, professional and objective. Native people like her are abundant in Australia and New Zealand. In them, I see the integration of ancient and modern cultures, the strong exploratory power and cultural debugging power of human beings.
