| The wide influence of the climatic oscillation and the related ecological changes around the Last Glacial Maximum (LGM) on driving prehistoric dispersal and cultural transitions of modern human has been widely acknowledged among archaeologists. Using the phylogeographic analyses of specific molecular markers, the ancient dispersal around the LGM was indicated to leave some geographic signatures... more |

| Recent progress from Yang xiaojun’ laboratory indicated that traditional genera Actindorua and Pomatorhinus (Timaliidae, Aves) are both paraphyletic, which indicated more complicated avian evolution in eastern Asian. In combination with morphology, it is recommended splitting both genera into two genera respectively. There is a significant pattern of north-south division inside traditional bar... more |

Researchers at Kunming Institute of Zoology, Chinese Academy of Sciences (KIZ, CAS) found that alternative splicing tends to diminish in the process of new gene origination.
Alternative splicing is a process that allows the production of a variety of different proteins from one gene only. And new gene origination is a fundamental process underlying evolution of biological diversity. Yet, th... more |

A regional montane reserve system should cover the entire elevational gradient and multiple slopes, rather than only the montane crest, suggested WU Fei, a PhD candidate at Kunming Institute of Zoology, Chinese Academy of Sciences.
WU and his supervisors did point counts to sample bird communities in four elevational zones, on eastern and western slopes, during both the breeding and the non... more |

Analysis discounts idea that hosts evolve to punish misbehaving symbionts
Applying employment contract theory to symbiosis, a new paper suggests mutually beneficial relationships are maintained by simple self-interest, with partners benefiting from healthy hosts much as employees benefit from robust employers. The new work discounts the theory that host species have evolved to promote symbi... more |
