封面故事： 鸭嘴兽基因组完成测序Genome analysis of the platypus reveals unique signatures of evolution鸭嘴兽（Ornithorhynchus anatinus）是一种独特的卵生哺乳动物，能泌乳，有毒液和一个喙。它甚至还有一个供在水下觅食使用的电传感系统。鸭嘴兽是从哺乳动物最根部的分支进化来的单孔目动物，既有爬行类的特 ...

早就听说过鸭嘴兽是下蛋的,也是哺乳的.但是最新一期Nature(Nature 8 May 2008 Volume 453 Number 7192)发表学术论文:科学家通过基因组序列比对,发现鸭嘴兽应该处于哺乳动物,爬行动物和鸟类进化的分支点.Genome analysis of the platypus reveals unique signatures of evolutionNature 453, 175-183 (8 May 200 ...
