共同起源 Common descent
（重定向自Common ancestor）
共同起源（英语：Common descent）是指一群生物体拥有最近共同祖先的情况。在进化论中，所有地球上的生命源于最后共同祖先或最后共同祖先基因池。这个祖先首先演变成细菌，接着是古细菌，最后是真核生物。所以，原生生物比真核生物更早出现于地球。这个结论物从分析各种生物的遗传物质(DNA)所得出的结果。

Common descent 共同起源
（重定向自Common ancestor）
Common descent describes how, in evolutionary biology, a group of organisms share a most recent common ancestor. There is evidence of common descent that all life on Earth is descended from the last universal ancestor.
Common ancestry between organisms of different species arises during speciation, in which new species are established from a single ancestral population. Organisms which share a more recent common ancestor are more closely related. The most recent common ancestor of all currently living organisms is the last universal ancestor, which lived about 3.9 billion years ago. The two earliest evidences for life on Earth are graphite found to be biogenic in 3.7 billion-year-old metasedimentary rocks discovered in western Greenland and microbial mat fossils found in 3.48 billion-year-old sandstone discovered in Western Australia. All currently living organisms on Earth share a common genetic heritage (universal common descent), with each being the descendant from a single original species, though the suggestion of substantial horizontal gene transfer during early evolution has led to questions about monophyly of life.
