Abstract
The neural circuits that control elasmobranch fins and the mammalian limbs have been found to exhibit striking similarities at the molecular, cellular and behavioral levels. The implication is that the neural substrate underlying limb control had already evolved 420 million years ago.
摘要
控制鲨鱼鳍和哺乳动物四肢的神经回路在分子、细胞和行为水平上表现出惊人的相似性。这意味着控制肢体的神经基质早在 4.20 亿年前就已经进化出来了。
