If this were true, it would also give excellent evidence to support the theory of "panspermia."
如果这项结论成立，它将为“有生源说(panspermia)”理论提供有力的证据。
That raises the possibility that life on Earth arrived here on a meteorite - a concept called panspermia.
这也为一种叫做有生源说的概念提供了可能性，这一概念认为地球上的生命是由小行星带来的。
The professor and his late colleague Sir Fred Hoyle championed the so-calledd " panspermia" theory from the 1960s.
自从上世纪60年代起，维克拉马辛教授和他的已故同事霍伊尔便倡导“有生源说（或称：胚种论）”的理论。
Researchers plan to evaluate the likelihood of panspermia by studying whether microorganisms can survive an interplanetary journey.
研究人员打算研究：微生物是否可以在星际旅行中存活，并据以评估胚种说存在的可能性。
For panspermia to occur, however, microorganisms need to survive not only ejection from the first planet and atmospheric entry to the second but the interplanetary voyage itself.
然而，胚种说真要发生，微生物除了从第一颗行星喷发、进入第二颗行星的大气时必须幸存之外，还要能在整个行星际旅程中保住小命。
The panspermia hypothesis posits that living cells or their precursors could have emerged on another planet or moon billions of years ago and hitched a ride to Earth on a meteorite.
“胚种假说”假设：活细胞或其前驱物可能于数十亿年前发源自其它行星或月球上，并且搭陨石的便车来到地球。
