Comprehensive foreign media reports on November 26，Open academic journal Elife official website headquarters in Cambridge, Britain released the research results of scholars such as Jessica Thomas such as Jessica Thomas。Research shows，Human hunting is one of the important reasons for the extinction of the giant bird in the mid -19th century。

Big Skin is a large diving bird that will not fly，The cold zone distributed bet365 Play online games on the coast along the North Atlantic，On the East Coast of North America、Iceland and Scotland coast is islands near the coast、Scandinavia's Navia Peninsula all have habitats。It is reported，Daquan once had millions of，But for a long time, it has been hunting by humans for a long time，Eventually in the 1840s, we moved to extinction。

To confirm whether human hunting is the only reason for the extinction of the species，Thomas et al. Plays ancient genetic data about 10,000 years ago、Ocean current data based on the global positioning system，and the survivability of the large sea bird bet365 best casino games population conducted a comprehensive analysis。Researchers sort the mitochondrial genome of 41 seabeling individuals from the geographical range of the species，and using the analysis results to rebuild the population structure and dynamics of the Big Park for nearly 10,000 years。THOMAS Gilbert, a professor of genetics at the University of Copenhagen, Danish University of Copenhagen, said，These birds are not threatened by environmental changes，What caused them to be extinct is likely to be human hunting pressure。

Gary Carvalho, a professor of zoology at Bange University, bet365 Play online games believes，This research helps to reveal how the development of natural resources that industrial scale causes a large number in a short time、Diverse species of genes directed to extinction。Michael KnApp, a researcher at the physique anthropology researcher at the University of Altago, New Zealand, said，This study reveals the necessity of monitoring the behavior of commercial capture species，Especially in the fields of relatively scarce ocean and other fields。This will help build a platform for sustainable ecosystems，Make sure that more effective protection work goes well。
