That Bacteria, Archaea and Eukarya (eukaryotes) represent three separate domains of Life, no one having evolved from within any other, has been taken as fact for three decades. Recent work shows this to be untrue. Eukarya arose from well within Archaea and are specifically related to newly discovered archaeal species with eukaryote-like features.
三十年来,人们一直认为细菌、古菌和真核生物(eukaryotes)代表了生命的三个独立领域,没有任何一个是从其他领域进化而来的。最近的研究表明事实并非如此。真核生物起源于古菌内部,与新发现的具有真核生物特征的古菌密切相关。
