Mitochondrial Genome of 22,000-year-old Giant Panda From Southern China Reveals New Panda Lineage
Genetic reconstructions based on present-day panda populations likely do not accurately depict their evolutionary history, but no mitochondrial (mtDNA) and nuclear genomes have been retrieved from ancient giant pandas to give a different story. This has changed with a new study in Current Biology (https://doi.org/10.1016/j.cub.2018.05.008) led by Professor FU and her team in the Molecular Paleontology Lab at the Institute of Vertebrate Paleontology and Paleoanthropology (IVPP), Chinese Academy of Sciences. In this study, they sequence the complete mtDNA of a ~22,000-year-old giant panda specimen. This giant panda was found by Professor ZHANG Yingqi at IVPP and the caving team (Beijing Caver ) in August 2014 at the Cizhutuo Cave located in the Leye County of Guangxi Province in China (Figure 1-2). That it lived around the time of the Last Glacial Maximum (LGM) makes it the oldest panda genetically sequenced to date.
