这些动物“冷知识”，看看意外不意外（趣科普）

Group 1 - The research team from Kunming Institute of Zoology has sequenced the genomes of 17 ancient dogs, marking the first acquisition of ancient dog genomes from China, and constructed a lineage evolution map of domestic dogs from East Asia to Western Eurasia [2][3] - The study reveals that a unique ancient lineage of domestic dogs existed in China 5,000 years ago, with subsequent gene flow from Siberian and Western ancient dog lineages, while ancient East Asian ancestry spread widely across the Eurasian steppe [2] - The findings indicate that the migration events of domestic dogs closely coincide with human migrations over the past 10,000 years, reflecting the intimate relationship between dogs and humans throughout history [3] Group 2 - The Kunming Institute of Zoology has initiated the "Macaque Biological Resource Bank" project, collecting genomic data from 919 Chinese macaques and 52 phenotypic data points, revealing unique genetic advantages such as higher genetic diversity and lower genetic load [4] - The study identifies harmful mutations in the DISC1 gene that lead to phenotypes in macaques similar to human mental disorders, providing an ideal animal model for mental health research [4] - Significant differences in drug target gene functions among individual macaques suggest the need for genotyping or sequencing of relevant drug target genes before conducting pharmacological evaluations [4] Group 3 - The international "Primate Genome Project" led by Kunming Institute of Zoology has systematically elucidated the evolutionary history and population dynamics of gibbons, as well as the genetic basis for their distinctive long arms [5] - The research team constructed the most comprehensive gibbon genome dataset to date, covering 18 extant gibbon species, and provided genomic evidence for the evolutionary relationships among various gibbon genera [5] - A specific deletion in a regulatory region of core genes controlling limb development was identified, which may play a crucial role in the evolutionary elongation of gibbon limbs [5]
