A re-examination of the mitochondrial genomes of unisexual salamander lineages, published in BMC Evolutionary Biology, shows them to be the oldest unisexual vertebrates known, having been around for 5 million years. This presents a challenge to the prediction that lack of genetic recombination is a fast track to extinction. See research article http://www.biomedcentral.com/1471-2148/10/238.
重新审视发表在《BMC 进化生物学》上的孤雌生殖蝾螈谱系的线粒体基因组表明，它们是已知最古老的孤雌生殖脊椎动物，已经存在了 500 万年。这对缺乏遗传重组是快速灭绝的预测提出了挑战。详见研究论文，网址：http://www.biomedcentral.com/1471-2148/10/238。
