《奇迹星球》是由NFB，日本NHK，发现频道和科学频道共同制作的5部视频系列。在超过40亿年的历史中，地球一直是反复发生的剧烈气候变化的所在地，这些气候变化导致了物种大灭绝。然而，生活依然存在。实际上，这些破坏了地球生命的灾难也帮助其从最简单的微生物演变为当今星球上发现的复杂性和多样性。《奇迹星球》（Miracle Planet）包括定位镜头，对世界上最重要的科学家的采访和尖端的计算机技术，是一个由五个部分组成的系列，讲述了地球神秘演变的深刻而令人着迷的故事。[编辑]???暴力过去???地球是由于多次小行星碰撞而诞生的，小行星碰撞是由一次巨大的撞击事件产生的。然后，地球的大小吸引了巨大的陨石，这些陨石撞击了其中，导致超高温的岩石蒸气覆盖了整个表面，并蒸发了所有海水。最早的生命形式逃避到地狱中，幸免于难，一次又一次地奇迹般地出现。地球经历了无数灾难性事件，生命通过获得新的生存能力来生存，以度过每次危机。人类是生命进化史上的一部分，生命史与反复发生的灾难事件密切相关。为什么地球能够进化为宜居的星球，而火星却无法进化为宜居的星球呢？在该系列的开篇情节中查找。[编辑]??雪球地球???假设“雪球地球”解释了由最早的生命形式引起的冰河时代导致了进化的飞跃。大型生活。微生物产生的大气甲烷最初使地球变暖。随着产生氧气的微生物（光合剂）的出现，大气中的甲烷被降低。结果是地球变冷了，原始海洋冻结了1000米深，在经历长达数百万年的长时间强烈冰川期之后，大多数生命可能已经灭绝了。但是，一些生命得以幸存，也许是在火山口附近形成的水坑中。二氧化碳在空气中累积是因为厚厚的冰盖阻止了海水吸收它。二氧化碳产生的温室效应最终融化了冰，并加入了光合作用。巨大的融化之后，超级飓风肆虐并搅动了海水，为生命的繁荣和发展胶原蛋白创造了理想的条件。利用胶原蛋白，生命形式能够构建更大的身体，并且首次出现了多种生物，称为埃迪卡拉生物群。??《新边疆》???第3集讲述了“大陆漂流”如何将我们的祖先带入陆地的故事。四亿年前，原始大陆周围的浅海是大多数生物的栖息地。像劳拉西亚这样的超大陆形成后，浅海的面积减小了。一些物种发现内陆的淡水家园摆脱了在海洋中生存的挣扎，不断的漂移导致形成了巨大的山脉。这些山峰阻挡了大气流，形成了下雨的云。雨水聚集在山脚下筑起了河流。我们的祖先Eustenopteron居住在加里东山脉脚下的河流中，Miracle Planet is a 5-video series co-produced by the NFB, NHK Japan, the Discovery Channel and the Science Channel. Over its more than 4-billion-year history, Earth has been home to repeated violent climatic changes, which have caused mass extinctions. And yet, life has survived. In fact,these same catastrophes that devastated life on Earth also helped bring about its evolution from the simplest microbes to the complexity and diversity that is found on the planet today. Featuring location footage, interviews with the world�s foremost scientists and cutting-edge computer technology, Miracle Planet is a five-part series that recounts the profound and gripping story of Earth�s mysterious evolution. The Violent Past Earth was born as a result of repeated asteroid collisions, the moon created by a single giant impact event. Then, Earth's size attracted huge meteorites, which slammed into it, causing super-high-temperature rock vapor to cover the entire surface and evaporate all ocean water. The earliest life-forms survived such infernal events by escaping deep into the ground, miraculously emerging again and again.The Earth has gone through innumerable catastrophic events, and life has survived by acquiring new abilities to live through each crisis. Humans are part of the grand history of life's evolution, which has been closely intertwined with repeated cataclysmic events.Why was Earth able to evolve into a livable planet, but not Mars, which failed to hold its atmosphere and oceans? Find out in the opening episode of the series. Snowball Earth The hypothesis "Snowball Earth" explains that ice ages, caused by the earliest life-forms, resulted in an evolutional leap � larger-sized life. Atmospheric methane created by microbes initially kept the Earth warm. As microbes that produce oxygen (photosynthesizers) emerged, atmospheric methane was lowered. As a result Earth cooled and the primeval ocean froze to 1,000 meters deep.Most life may have become extinct during a long period of intense glaciation believed to have lasted several million years. However, some life survived, perhaps in puddles created near volcanic craters. Carbon dioxide accumulated in the air because thick ice sheets prevented ocean water from absorbing it. A green-house effect, created by carbon dioxide, finally melted the ice and fed photosynthesizers.Hyper hurricanes raged after the great meltdown and stirred up the ocean water, creating an ideal condition for life to prosper and develop collagen. Using collagen, life-forms were able to build larger bodies, and a variety of creatures, called Ediacara biota, emerged for the first time. New Frontiers Episode 3 tells the story of how "continental drift" brought our ancestors onto the land. Four hundred million years ago, shallow seas around primeval continents were home to most life-forms. The size of the shallow seas decreased as the supercontinents, like Laurasia formed. Some species found freshwater homes inland to escape from a struggle for survival in the ocean.Continental drift caused the formation of huge mountains. The peaks blocked atmospheric currents, creating clouds that rain. The rain gathered to make rivers at the foot of the mountains. Our ancestor, Eustenopteron, came to live in those rivers at the foot of the Caledonian mountains, where primeval trees called Archaeopteris developed a mild and stable environment. The leaves of Archaeopteris supplied nutrients for life, but caused oxygen depletion during dry seasons. Eustenopteron and other fish species developed proto-lungs to survive in low oxygen. Huge predators appeared as well. Acanthostega sought to hide from predators in Archaeopteris branches that piled in water near riverbanks. They made their way forward by pushing the branches aside, thus developing a forefoot. After several million years, Pederpes finally made the first step onto the land. Extinction and Rebirth Life on Earth has experienced five great extinctions. The worst occurred about 250 million years ago during the Permian period. Our ancestors at that time were mammal-like reptiles. The super-plume theory attempts to explain this extinction with a gigantic vertical flow of magma in Earth's mantle.About 300 million years ago, under the ocean trenches around the supercontinent Pangea, the end parts of the ocean plates dropped toward the core, creating a reactionary upward magmatic current that caused violent volcanic eruptions. A huge basaltic plateau in Siberia is believed to be evidence of this super-plume.According to the theory, carbon dioxide from volcanoes warmed Earth, causing methane-hydrate long frozen under the ocean floor to melt. Enormous amounts of methane were released into the air, accelerating global warming. The methane also depleted atmospheric oxygen, devastating plants. The oxygen depletion continued for about 100 million years.Reptiles adapted best by developing a unique air-sac system. Mammals were also forced to devise a way to adapt, so they evolved to nurture babies in a womb in order to send them adequate oxygen. Mammals also devised a diaphragm for efficient respiration. This caused them to lose the lower half of their ribs, but as a result they could lie on the ground while twisting their waist. Now they were capable of breast-feeding. Survival of the Fittest After the dinosaurs disappeared, the land was dominated by giant ground birds such as Diatrima. Continental drift, which had once caused the supercontinents to form, now broke up the huge landmasses. Mammals found an isolated niche for themselves in the Asian continent. Free from the attacks of giant birds, mammals could safely evolve there. In time, large, predatory mammals like Hyenodont emerged.When global warming melted the ice that had covered the land bridge between Asia and North America, a conflict erupted between Diatrima and Hyenodont. The winner was Hyenodont. It was the start of the golden age for mammals.Primates still hid from their predators in treetops, where they developed a unique ability � stereoscopic vision. Now that they could measure the distance between things, they could easily jump from branch to branch. As a result of global warming, trees grew higher and thick forests covered entire continents. Primates could live without going down to the ground, where dangerous predators roamed.Then, as Antarctica was torn apart from other continents and became a world of ice and snow, it started cooling the entire Earth. Forests disappeared, and most of the primates became extinct. Anthropoids developed a fovea, part of the eye responsible for sharp vision, which enabled them to survive by efficiently finding food. Stronger eyesight brought about a side effect � the ability to communicate through facial expressions. This led to the formation of a "society" among anthropoids.
