Critical analysis of the phylogeny of prokaryotes is in its infancy. Woese and others have made the startling proposal that methane-producing bacteria and a few others form a phyletically unified group, the Archaebacteria, as old and as diverse (although not now as numerous) as all other bacteria. The only critique of this proposal is inadequate. Here we present an alternative view, that the Archaebacteria were derived from other bacteria and contain the ancestor of a cell which engulfed others, eventually to become the first eukaryote.
对原核生物系统发育的批判性分析尚处于起步阶段。沃斯等人提出了一个惊人的观点，即产甲烷细菌和其他一些细菌形成了一个系统发育上统一的群体——古细菌，它们与所有其他细菌一样古老且多样（尽管现在数量不如其他细菌多）。对这一观点唯一的批评并不充分。在此我们提出另一种观点，即古细菌源自其他细菌，并且包含一种吞噬其他细胞的细胞的祖先，这种细胞最终成为了第一个真核生物。
