Today, scientists are not so sure that life began on or near the Earth’s surface. Everywhere we look, there seems to be life \u2013 even several kilometres underground. It may be that life began at the bottom of the oceans, where hot springs provided energy instead of sunlight.<\/p>\n<\/div>\n

Otra idea es que la vida (o al menos sus componentes qu\u00edmicos fundamentales) provenga del espacio. Durante los primeros tiempos de la Tierra, muchos cometas ca\u00edan sobre su superficie. Los cometas poseen abundantes sustancias qu\u00edmicas basadas en carbono, que pueden haber sido el origen de la vida.<\/p>\n

Tambi\u00e9n es posible que la vida haya viajado de un planeta a otro. Parece que la vida es lo suficientemente resistente como para sobrevivir un largo viaje por el espacio. El choque de cometas o meteoritos de gran tama\u00f1o contra la Tierra pudo haber arrojado grandes cantidades de rocas al espacio. Si una bacteria viajase de polizonte en estas rocas, finalmente podr\u00eda posarse en otro planeta.<\/p>\n

Del mismo modo, un meteorito originario de Marte podr\u00eda transportar vida marciana (si existiera) a la Tierra. En 1996, un grupo de cient\u00edficos revel\u00f3 al mundo que hab\u00eda encontrado en la Ant\u00e1rtida una roca procedente de Marte que pose\u00eda esas caracter\u00edsticas. Sin embargo, otros cient\u00edficos ponen en duda su investigaci\u00f3n.<\/p>","protected":false},"excerpt":{"rendered":"
