- Symmetry 12y agoHere's an example. The structures inside the meteorite were't proved to be life but if they had been alive they would have survived the trip from Mars to Earth. http://en.wikipedia.org/wiki/Allan_Hills_84001 http://en.wikipedia.org/wiki/Allan_Hills_84001
- Luc 12y agoThat trip took 17 million years according to the Wikipedia article. Seems a bit long for anything to survive, surely?
- danieltillett 12y agoWe have pulled living bacteria out of sediment 100 million years old so 17 million years is nothing. More importantly this is just the time for this particular meteorite - people have done the calculations and some meteorites do the trip in around a year.
- Luc 12y agoWoah, amazing. Here's a fun article about reviving supposedly 250 million year old spores trapped in salt crystals: http://www.its.caltech.edu/~bi1/Bi1__Micro-_to_Macro-Biology/Exams_files/Ancient%20DNA%20paper.pdf http://www.its.caltech.edu/~bi1/Bi1__Micro-_to_Macro-Biology...
