团队为蜜蜂进行了一场全球"人口普查"。他们整合了庞大的全球数据库、各国物种清单以及详尽的文献 记录,并运用统计模型对186个国家的蜜蜂物种数量进行了精确测算。结果不仅刷新全球总数纪录,更 揭示了一个此前不为人知的分布格局:在瑞典、瑞士等欧洲国家,蜜蜂家族的名录已相对完备;但土耳 其预计还有843种蜜蜂等待科学家去发现和命名。 团队表示,了解一个地方有多少种蜜蜂,绝不仅仅只是数字游戏,而是直接关系到人们如何规划土地、 如何开展保护,甚至关乎人们对整个生态系统和进化历程的理解。作为自然界至关重要的"红娘",蜜蜂 的多样性是维系农业收成和生态环境健康的基石。 研究显示,自1960年以来,科学家以每年约117种的速度稳定地为蜜蜂家族"上新"。由于分类学专家匮 乏,按照目前的速度,要填补这一认知空白,至少还需要30到45年。 来源:科技日报 科技日报记者 刘霞 究竟有多少种蜜蜂在这颗蓝色星球上采花酿蜜?澳大利亚伍伦贡大学研究团队给出了迄今最精确的答 案,为我们描绘出一幅更清晰多彩的全球蜜蜂地图。他们首次系统测算出全球蜜蜂物种的总数:介于 24705种到26164种之间,比此前认为的多了3700种到5200种。相关论文发 ...

Core Insights - An international team led by Chinese scientists has discovered a new species of gibbon, named "Imperial Gentleman Gibbon," through ancient DNA sequencing technology, published in the journal Cell [1][5]. Group 1: Discovery and Research Findings - The Imperial Gentleman Gibbon was found in the burial site of Empress Xia, the grandmother of Qin Shi Huang, during excavations in 2004, where gibbon remains were uncovered in a burial pit [1][6]. - Initial morphological studies in 2018 suggested it was a new genus and species, but further DNA analysis in 2025 confirmed it as a new species within the Hoolock genus, closely related to the Hainan gibbon [5][8]. - The burial site also contained remains of other animals such as leopard cats, lynxes, Asian black bears, and red-crowned cranes, along with bronze chains and feeding tools, indicating a diverse collection of animals [6][8]. Group 2: Cultural and Historical Context - The findings suggest that Empress Xia had a fondness for rare animals, which were likely kept in royal gardens and buried with her, reflecting ancient beliefs about life and death [8]. - The research also reinforced the classification of the "Tianxing Gibbon" as an independent species and identified the gene "SHH" that regulates the length of gibbons' arms [8].
