然而，希望奇异鱼与更进步的肺鱼类之间仍存在明显的形态断层。此前在北美泥盆纪布拉格期地层 发现过顶嵴鱼化石，但该化石因严重扁平，无法展示脑颅等关键内部结构，导致早期肺鱼演化的关键环 节始终悬而未决，甚至有学者对希望奇异鱼的肺鱼属性提出质疑。 肺鱼，是一种神奇而古老的生物，部分种类能在极端干旱条件下用肺呼吸，其演化历史可追溯至早 泥盆世洛赫考夫期（约4.15亿年前）。如今，全球仅存三个属的肺鱼，分别是非洲肺鱼、南美肺鱼以及 澳洲肺鱼。其中，澳洲肺鱼堪称"活化石"，它的身体结构从中生代起就几乎没有变化，仿佛时间在它身 上按下了"暂停键"。 近日，中国科学院古脊椎动物与古人类研究所朱敏院士团队在国际学术期刊《当代生物学》发表重 要研究成果论文，该研究发现，在云南昭通下泥盆统中，团队发现了一种名为"云南古嵴鱼"的原始肺鱼 化石，为破解早期肺鱼演化的关键环节提供了珍贵的实物证据。 肺鱼的演化历程充满适应性智慧。在演化早期，绝大多数肺鱼生活在海洋环境中，身体呈现高度骨 化特征。随着地质历史的推进，它们逐渐向淡水环境迁移，并演化出独特的生存策略。当旱季来临、水 源干涸时，肺鱼会钻进泥中进入夏眠状态，静静等待雨季复苏，这种"绝 ...
