牙齿可能是分生的单位和冠的形态发生导致牙齿特异性分布的功能细胞。由于异齿是从同齿衍生而来,理解牙齿形态发生的一种方法是解开同齿物种中所涉及的现象,然后描述导致具有特定功能能力的物种特异性齿系的进化的“工作”。古生物学家和发育生物学家的互动应该开始。我天真的“发育”观点只能说明小鼠牙齿形态发生和细胞分化的一个方面。主要关注的是试图区分已知的事实和推测,假设和预期或推断的确定性,提请注意相互矛盾的数据,建议一些进一步的调查,并主张分子解释应该建立在无可争议的形态学数据的观点。
Teeth are probably meristic units and crown morphogenesis leads to tooth specific distribution of functional cells. Since heterodonty is derived from homodonty, one way to understand tooth morphogenesis would be to unravel the involved phenomena in homodont species and then to characterize the "put up job" of evolution leading to species specific dentitions with particular functional abilities. Interaction of paleontologists and developmental biologists should be initiated. My naive "developmental" point of view will illustrate only one facet of mouse tooth morphogenesis and cytodifferentiation. The main concern will be to try to discriminate between known facts and speculations, between hypotheses and anticipated or deduced certitudes, to call attention to conflicting data, to suggest some further investigations and to advocate the point of view that molecular interpretations should be founded on indisputable morphological data.
