En esta obra, el divulgador cient\u00edfico y gran escritor Isaac Asimov nos ilustra acerca de la andadura de la vida a trav\u00e9s del tiempo, hasta llegar a la situaci\u00f3n actual, a la vez que nos brinda bien fundamentadas hip\u00f3tesis acerca de nuestras posibilidades cara al futuro. En primer lugar, retrocedemos millones de a\u00f1os para seguir el desarrollo de la vida multicelular a partir de la primera mol\u00e9cula nucleoprote\u00ednica. Seg\u00fan Asimov, la sociedad futura -la actual ya lo es en buena parte- tendr\u00e1 que constituir como un organismo multicelular que nos sirva de base para emprender la conquista del Cosmos. En veintis\u00e9is ensayos, el autor explora los fen\u00f3menos de nuestro Universo que afectan directamente al hombre y a toda la dem\u00e1s vida terrestre en el pasado, presente… y futuro. Ante todo, Asimov establece qu\u00e9 puede considerarse realmente vivo. En la marcha de los filos nos ofrece una clara idea de los comienzos de la evoluci\u00f3n. Asimismo, el autor nos habla del imprescindible papel de las plantas en la existencia de la vida. Tambi\u00e9n merece su atenci\u00f3n el cerebro humano, y establece comparaciones entre \u00e9ste y el de los animales, presentes y pasados. Asimov advierte seriamente acerca de los peligros que entra\u00f1ar\u00eda romper el equilibrio ecol\u00f3gico.En la segunda parte de la obra, el autor aborda el tema de la imposibilidad de vivir aislados, nos explica la influencia del Sol en el desarrollo de las religiones, el proceso que condujo a descubrir las razones del contagio de las enfermedades, lo que debe la Astronom\u00eda al rostro de la Luna, el laborioso proceso del descubrimiento del arg\u00f3n, lo que representan el agua y la sal… En la tercera y \u00faltima parte se nos habla del desarrollo de las comunicaciones humanas mediante la tecnolog\u00eda, en particular, las computadoras y los sat\u00e9lites de comunicaciones. Asimov dedica unas reflexiones acerca de los transportes terrestres y su futuro, abordando seguidamente el problema de la velocidad. Seg\u00fan el autor, el desarrollo de la agricultura en las pr\u00f3ximas d\u00e9cadas resultar\u00e1 algo fundamental para la Humanidad.<\/p>\n","protected":false},"excerpt":{"rendered":"
