辽宁海城小孤山披毛犀化石的古DNA分析
Ancient DNA Analysis of Woolly Rhinoceros in Xiaogu Mountain,Haicheng City, Liaoning Province
摘要
Abstract
In this study, 1 080 bp sequence of mitochondrial cytochrome b gene was successfully retrieved from a Late Pleistocene wooly rhinoceros fossil excavated from Xiaogu Mountain, Haicheng City, Liaoning Province. Analysis of phylogenetic tree with horse as out group showed the same topological of phyloge-netic trees using Neighbor-Joining and Maximum likelihood methods. Our results suggested that woolly rhinoceros has relatively close relationship with extant sumatran rhinoceros. Furthermore, the phylogenetic position of Xiaogu Mountain sample was always at the root of this branch. Finally, our data revealed that the woolly rhinoceros from China showed higher gene divergency than European and Northern Asian counterparts. Our study provides molecular evidence for the origin and extinct of woolly rhinoceros.关键词
