大规模灭绝一再塑造了全球生物多样性。白垩纪-古近纪(K-Pg)大规模灭绝导致许多脊椎动物群体的灭亡,其后果是幸存的哺乳动物、鸟类、青蛙和硬骨鱼迅速多样化。然而,K-Pg 灭绝对蛇类(包括 3,700 多种现存物种的主要掠食者分支)进化的影响仍然知之甚少。在这里,我们将广泛的分子数据集与系统发育和地层限制的化石校准相结合,以推断蛇类的进化时间尺度。我们揭示了与 K-Pg 大规模灭绝相关的冠蛇潜在的多样化,这是由现存主要分支 Afrophidia 在亚洲的成功殖民导致的。脊椎形态测量表明,古近纪期间海蛇的形态专业化不断增强。 K-Pg 之后蛇的扩散模式强调了这次大规模灭绝事件对于塑造地球现存脊椎动物群的重要性。蛇是现存脊椎动物中最成功的类群之一,但其多样化的时间尚不清楚。 Klein 等人结合分子钟、化石和生物地理学。研究表明,在白垩纪末期大规模灭绝期间,蛇经历了多样化并经历了扩散。
Mass extinctions have repeatedly shaped global biodiversity. The Cretaceous-Paleogene (K-Pg) mass extinction caused the demise of numerous vertebrate groups, and its aftermath saw the rapid diversification of surviving mammals, birds, frogs, and teleost fishes. However, the effects of the K-Pg extinction on the evolution of snakes—a major clade of predators comprising over 3,700 living species—remains poorly understood. Here, we combine an extensive molecular dataset with phylogenetically and stratigraphically constrained fossil calibrations to infer an evolutionary timescale for Serpentes. We reveal a potential diversification among crown snakes associated with the K-Pg mass extinction, led by the successful colonisation of Asia by the major extant clade Afrophidia. Vertebral morphometrics suggest increasing morphological specialisation among marine snakes through the Paleogene. The dispersal patterns of snakes following the K-Pg underscore the importance of this mass extinction event in shaping Earth’s extant vertebrate faunas. Snakes are one of the most successful groups of living vertebrates, but the timing of their diversification is unclear. Combining molecular clocks, fossils, and biogeography, Klein et al. show that snakes experienced a diversification, and underwent dispersal, around the time of the end-Cretaceous mass extinction.
