作为生命史上最重要的事件之一，产氧光合作用的起源必须排在生命本身的起源之后。比尔·肖普夫（Bill Schopf）证明，早期的光合作用与现代蓝细菌（32）相似，它们在数亿年的时间里悄悄地产生氧气，使地球成为一个更美好的居住地。在建立了臭氧紫外线屏障之后，蓝细菌与真核细胞建立了一种非凡的伙伴关系：它们变成了叶绿体。装备了叶绿体，早期的植物准备好殖民土地和绿色地球。这篇评论叙述了我们对叶绿体进化的理解从过去25年来的重大飞跃。
The origin of oxygenic photosynthesis must rank just after the origin of life itself as one of the most significant events in the history of life. The early photosynthesizers, which Bill Schopf has shown were similar to modern cyanobacteria (32), made earth a nicer place to live by quietly cranking out oxygen over hundreds of millions of years. Having established an ozone UV shield, the cyanobacteria then entered into an extraordinary partnership with eukaryotic cells: They became chloroplasts. Equipped with chloroplasts, the early plants were ready to colonize the land and green the planet. This review recounts major leaps in our understanding of chloroplast evolution from the preceding 25 years.
