Genetic Structure and Extinction of the Woolly Mammoth, Mammuthus primigenius

The interval since circa 50 Ka has been a period of significant species extinctions among the large mammal fauna. However, the relative roles of an increasing human presence and a synchronous series of complex environmental changes in these extinctions have yet to be fully resolved. Recent analyses of fossil material from Beringia have clarified our understanding of the spatiotemporal pattern o...

Evolution of endogenous retrovirus-like elements of the woolly mammoth (Mammuthus primigenius) and its relatives.

Endogenous retrovirus-like elements characterizable by a leucine tRNA primer (ERV-Ls) are reiterated genomic sequences known to be widespread in mammals, including humans. They may have arisen from an ancestral foamy virus-like element by successful germ line infection followed by copy number expansion. However, among mammals, only primates and rodents have thus far exhibited high copy number a...

Population-level genotyping of coat colour polymorphism in woolly mammoth (Mammuthus primigenius)

Patterns in the spatial or temporal distribution of genotypes may be indicative of natural selection. Previous work on the woolly mammoth melanocortin-1 receptor (Mc1r) gene identified three polymorphic positions that suggest Pleistocene populations may have harboured both lightand dark-haired mammoths (Rompler et al., 2006, 313: 62). Here, we extend this work and present the first populationle...

Complete Mitochondrial Genome and Phylogeny of Pleistocene MammothMammuthus primigenius

Phylogenetic relationships between the extinct woolly mammoth (Mammuthus primigenius), and the Asian (Elephas maximus) and African savanna (Loxodonta africana) elephants remain unresolved. Here, we report the sequence of the complete mitochondrial genome (16,842 base pairs) of a woolly mammoth extracted from permafrost-preserved remains from the Pleistocene epoch--the oldest mitochondrial genom...
