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.
A pergunta se existe vida em Marte relacionada com a vida na Terra ficou muito obscura, porque como sabemos agora, meteoritos de Marte alcançaram a Terra, e existe material que pode ter sido trocado entre os dois planetas.
