Los seres vivientes respiran, se alimentan, crecen y se reproducen. Los hay desde la bacteria unicelular m\u00e1s simple, a plantas, aves, animales y humanos. La Tierra es el \u00fanico mundo que conocemos que haga posible la vida, pero nadie sabe c\u00f3mo comenz\u00f3. Parece que uno de los factores determinantes para su surgimiento fue la interacci\u00f3n de ciertas sustancias qu\u00edmicas. Pero lo que transforma estas sustancias en formas vivientes sigue siendo un misterio.<\/p>\n<\/div>\n

Los estudios de rocas antiguas demuestran que la vida comenz\u00f3 en la Tierra hace cerca de 3.800 millones de a\u00f1os. En aquel momento, la Tierra era un lugar muy poco agradable. El aire era denso y venenoso. Los cometas y meteoritos ca\u00edan sobre el planeta.<\/p>\n

La joven Tierra era un mundo acu\u00e1tico con peque\u00f1as zonas de suelo seco. Muchos cient\u00edficos creen que la vida naci\u00f3 en los lagos y oc\u00e9anos. Muchos de los ingredientes de los que surgi\u00f3 la vida pueden haber llegado con cometas y meteoritos.<\/p>\n

Did life begin in the oceans?<\/p>\n

Los rayos y la luz ultravioleta del Sol pueden haber dividido los gases ricos en hidr\u00f3geno presentes en la atm\u00f3sfera. La energ\u00eda tambi\u00e9n puede haber procedido de fuentes termales del lecho marino, conocidas como \"fumarolas negras\". Con el paso del tiempo, los qu\u00edmicos simples se unieron formando qu\u00edmicos m\u00e1s grandes y complejos.<\/p>\n

Once these chemicals collected in the oceans or lakes, they formed an ‘organic soup’. One day, an accident occurred. A molecule began to make copies of itself. Earth had sprung to life.<\/p>","protected":false},"excerpt":{"rendered":"
