Abstract

In July 2016, a mummified carcass of an ancient wolf (Canis lupus) pup (specimen YG 648.1) was discovered in thawing permafrost in the Klondike goldfields, near Dawson City, Yukon, Canada (Figure 1A). The wolf pup mummy was recovered along a small tributary of Last Chance Creek during hydraulic thawing that exposed the permafrost sediment in which it was preserved. This mummified wolf pup is important to the local Tr'ondëk Hwëch'in people, who named it Zhùr, meaning 'wolf' in the Hän language of their community. Here, we report detailed morphometric, isotopic, and genetic analyses of Zhùr that reveal details of her appearance, evolutionary relationships to other wolves and short life-history and ecology. Zhùr is the most complete wolf mummy known. She lived approximately 57,000 years ago and died in her den during a collapse of the sediments. During her short life, she ate aquatic resources, and is related to ancient Beringian and Russian gray wolves and her clade is basal to all living gray wolves. VIDEO ABSTRACT.

摘要

2016 年 7 月,在加拿大育空地区道森市附近的克朗代克金矿区,永冻层解冻时发现了一具古代狼幼崽(Canis lupus)的木乃伊(标本 YG 648.1)(图 1A)。这只狼幼崽木乃伊是在一条名为“Last Chance Creek”的小支流旁被发现的,当时该支流正在进行水力解冻,从而使其中保存的永冻层沉积物暴露出来。这只狼幼崽木乃伊对当地的 Tr'ondëk Hwëch'in 人来说很重要,他们将其命名为“Zhùr”,在他们社区的 Hän 语言中意为“狼”。在这里,我们报告了对 Zhùr 的详细形态测量学、同位素和遗传分析,这些分析揭示了她的外貌、与其他狼的进化关系以及短暂的生活史和生态学的详细信息。Zhùr 是已知的最完整的狼木乃伊。她生活在大约 57000 年前,在沉积物坍塌时死在她的洞穴里。在她短暂的生命中,她吃水生资源,与古代的白令海和俄罗斯灰狼有关,她的分支是所有现存灰狼的基础。视频摘要。
