胚种

The confirmation of Mars-Earth panspermia would suggest that life, once started, could readily spread within a star system.

「火–地」胚说如获证实，表示生命一旦出现，便能轻系内扩散。

For this reason, the most commonly discussed panspermia scenario involves the transport of microbes or their precursors from Mars to Earth.

基于这个理由，最常受人讨论胚说就是：微生物或其前驱物，是从火送到地。
