Two captive populations could n ' t be defined as separate evolutionary significant units ( esus ) because of lacking of genetic divergence between them, and should be considered as a single esu in the conservation of the species. by comparing the sequences of control region of mitochondrial dna from three species of crocodiles, it is revealed that the smallest genetic diversity exists between alligator sinensis and alligator mississipiensis. a portion of mitochondrial nd4 and cytochrome b gene of 3 species of crocodilian was sequenced
百年來關于揚子鱷的分類地位存在著很多爭議，本文利用測得的揚子鱷（ alligatorsinensis ） 、暹羅鱷（ crocodlylussiamensis ）和灣鱷（ crocodylusporosus ）的mtdnand4和cytb基因序列，以及從genbank中獲得密西西比鱷、凱門鱷和海龜（ cheloniamydas ）的nd4基因和cytb基因相應片段，構建以海龜為外群的系統進化樹。 -
A new study of genes in humans and chimpanzees pins down with greater accuracy when the two species split from one. the evolutionary divergence occurred between 5 million and 7 million years ago, an estimate that improves on the previous range of 3 million to 13 million years in the past
據美國「生活科學」網12月19日報道，上述研究結果顯示，人類與黑猩猩在進化過程中的分化發生在500萬年至700萬年之前，這較之過去人們認為的時間段要精確得多。
