Our skeletons evolved from cartilaginous tissue, but it remains a mystery how cartilage itself first arose in evolution. Characterization of cartilage in cuttlefish and horseshoe crabs reveals surprising commonalities with chordate chondrocytes, suggesting a common evolutionary origin.
我们的骨骼由软骨组织进化而来，但软骨本身在进化中是如何首先出现的仍然是一个谜。乌贼和鲎软骨的特征表明与脊索动物软骨细胞具有惊人的相似性，这表明它们具有共同的进化起源。
