在过去的几年里，有鳞动物胎生的进化一直是科学界关注的焦点。特别是，从胎生到卵生的转变的可能性一直是激烈辩论的主题。一些研究表明，这种逆转比以前认为的更频繁。但是，没有一个提供确凿的证据。我们调查了这个问题，通过研究卵生和胎生血统的生殖双峰蜥蜴种Zootoca vivipara之间的系统发育关系。我们的研究结果表明，胎生种群不是单系的，并在奇偶校验模式发生了几个进化转变。最简约的方案涉及一个单一的起源胎生其次是逆转回卵生。这是第一个具有强有力的支持从胎生到卵生过渡的系统发育框架的研究。© 2006年，伦敦林奈学会，林奈学会生物学杂志，2006年，87，1-11。
The evolution of viviparity in squamates has been the focus of much scientific attention in previous years. In particular, the possibility of the transition from viviparity back to oviparity has been the subject of a vigorous debate. Some studies have suggested this reversal is more frequent than previously thought. However, none of them provide conclusive evidence. We investigated this problem by studying the phylogenetic relationships between oviparous and viviparous lineages of the reproductively bimodal lizard species Zootoca vivipara. Our results show that viviparous populations are not monophyletic, and that several evolutionary transitions in parity mode have occurred. The most parsimonious scenario involves a single origin of viviparity followed by a reversal back to oviparity. This is the first study with a strongly supported phylogenetic framework supporting a transition from viviparity to oviparity. © 2006 The Linnean Society of London, Biological Journal of the Linnean Society, 2006, 87, 1–11.
