火星为何有可能保留了生命起源的秘密 | Nathalie Cabrol
from TEDTalks 科学与医疗 · host TED
尽管我们喜欢把外星生物想象成是小绿人，但是它们更可能会是微生物。行星学家 娜塔莉·卡布罗尔 带领我们进入到火星微生物的搜寻中，这次搜寻一反直觉地把我们带到遥远的安第斯山脉湖泊里去。那里极端的环境——稀薄的大气和焦黄的土壤——相当接近35亿年前火星的地表环境。微生物在此适应生存的方式，也许恰好能告诉我们要去火星哪里寻找它们，并且能够帮助我们理解为什么有些微生物会通向文明，而另一些则走向灭亡。Translated by Yan PengReviewed by Xingyi Ouyang 歐陽杏儀
