在四足动物的身体平面图的起源过程中，四肢的发育基础和功能后果的修改越来越好地表征，但对四足动物头骨的进化了解较少。头骨数量的减少被假设为促进脊椎动物分支的形态和功能多样化，但其在四足动物最初崛起期间的影响尚不清楚。在这里，我们测试这一点，通过量化拓扑结构的变化，颅骨解剖化石和活类群括号中的鳍肢过渡，使用解剖网络分析。我们发现，在整个起源的四足动物的骨丢失不仅与骨-骨接触的复杂性增加，但也与整个晚古生代，这可能是有关的发展和/或机械限制拓扑多样性下降。我们还发现了10马之间的鳍肢和颅形态进化的偏移，这表明不同的进化驱动程序影响这些功能在四足动物的起源。头骨数量的减少在第一肢脊椎动物头骨的进化中起着关键作用。
The developmental underpinnings and functional consequences of modifications to the limbs during the origin of the tetrapod body plan are increasingly well characterized, but less is understood about the evolution of the tetrapod skull. Decrease in skull bone number has been hypothesized to promote morphological and functional diversification in vertebrate clades, but its impact during the initial rise of tetrapods is unknown. Here, we test this by quantifying topological changes to cranial anatomy in fossil and living taxa bracketing the fin-to-limb transition using anatomical network analysis. We find that bone loss across the origin of tetrapods is associated not only with increased complexity of bone-to-bone contacts but also with decreasing topological diversity throughout the late Paleozoic, which may be related to developmental and/or mechanical constraints. We also uncover a 10-Ma offset between fin-limb and cranial morphological evolution, suggesting that different evolutionary drivers affected these features during the origin of tetrapods. A reduction in the number of skull bones played a key role in the evolution of the skull in the first limbed vertebrates.
