Scientists from the penguin fossils extracted DNA

According to "Science Daily" reported net on the 19th, Australia and New Zealand scientists in New Zealand's endangered species, yellow eye penguin study, from the old penguin fossils extracted the DNA, identified a long-extinct species of penguins , That is, the Huai Taha Penguin (Waitahapenguin). Related papers published in the United Kingdom, "Journal of the Royal Society B" on. Australia ancient DNA, deputy director of the Center for the Study Group and a member of Jeremy? Austin, said the discovery confirmed the New Zealand mainland existing yellow eyes Penguin is not for pregnant Taha Penguin remnants of the tribe, but the recent migration from the Antarctic area in the past. Taha pregnant penguin in the Polynesian settlers after extinct, by the year 1500, yellow eyes from the penguins of the Antarctic area is located at the base areas migration to the mainland of New Zealand, replacing the Huai Taha extinct penguin, became the world's most rare And the protection of a good one of the penguin species. Penguin competition between the two has hampered the yellow eyes to the Penguins in the northern region of the expansion, but some of the changes in the populations of predators, such as the sharp decline in the number of sea lions, and so on, may have yellow eyes to the Penguins in the southern island of movement played a role in the promotion. Prior to the analysis of the fossil and other evidence show that the number of yellow eye penguins have been many widely distributed, but the current evidence suggests that its survival on the mainland of New Zealand's history of not more than 500 years. The researchers said that the surprising discovery of the species would show the way to the accident on people and the environment to respond, also showed that the extinction of the incident on the current environment to shape the role.
