| Neoteny is a unique phenomenon during human evolution. Compared to nonhuman primates, humans have delayed or slowed body development. This human-specific neotenous process, in view of evolutionary significance, provides an extended time window for brain development and neural network plasticity, a key factor affecting the formation of human intelligence. However, the genetic basis of human neot... more |

Recently, scientists unraveled the core gene regulatory network determining the reproductive division of labor in ants based on comparative transcriptomics study across diverse ant species from 3 different subfamily and 5 different genera.
Ant colony consists of one or more egg-laying queens, a large number of sterile workers and some winged sexual males and gynes (unmated queens). The repr... more |

Crested ibis (Nipponia nippon), a Chinese national protected animal, is one iconic example of endangered birds that have been saved from the blink of extinction. The species was once widely distributed in China, East Russia, Korea, and Japan before the 1860s. However, its population declined drastically in the late 19th and early 20th centuries, ultimately died out in most of the habitats ... more |

Viviparity (live-bearing) is a reproductive mode in which pregnant females maintain developing embryos inside their reproductive tracts and give birth directly to offspring. In contrast, oviparity (egg-laying) is the reproductive pattern in which females lay eggs that continue to develop independently of the mother until hatching. Viviparous species provide an environment for embryonic dev... more |

Recently, scientists from Kunming Institute of Zoology, Chinese Academy of Sciences discovered a new species of Yunnanilus, and named as Y. jiuchiensis.
Yunnanilus is an ecologically important genus distributed in lakes, marshes, and slow-flowing waters, with an affinity for karstic areas. The species of Yunnanilus known from Yunnan, Guizhou, Sichuan, and Guangxi regions of China as well as... more |
