english: The question as to whether there is life on Mars that is related to life on Earth has now been very muddied, because we now know, from Mars meteorites that have made it to Earth, that there's material that can be exchanged between those two planets.
non_english: Otázka, či život na Marse má nejaký vzťah k životu na Zemi je teraz veľmi hmlistá, lebo vďaka meteoritom z Marsu, ktorým sa podarilo trafiť Zem, vieme, že existuje určitá výmena materiálu medzi týmito dvomi planétami.
