查询词典 evolutionary

Therefore, the chiru attracted a lot of attentions of the Chinese government, conservation scientists and other conservative organizations in the world.In the present study, 57 chiru individuals were sampled from Arjin Shan Nature Reserve in Xinjiang, Chang Tang Nature Reserve in Tibet and Kekexili Nature Reserve in Qinghai. The present study, based on the analyses of the chiru mitochondrial control region with MEGA, DnaSP and ARLEQUIN programs, investigated into the genetic diversity background, evolutionary history and population relationships and aimed to provide scientific basis for the protection of the chiru.
