由大卫·阿滕伯勒（David Attenborough）主持并由PBS在2006年出版的科学纪录片-英语旁白也被称为：琥珀色时光机Science Documentary hosted by David Attenborough and published by PBS in 2006- English narrationalso known as: The Amber Time Machine
------------------------------------------------------
四千万年前，生活在温带森林中树木底部的各种昆虫群落偶然变成了粘稠的松脂树。仅仅67年前，一个名叫David Attenborough的小男孩就被给了琥珀色的石头，里面装有被埋葬的虫子。“地球的宝石”探索了保存在这个古老的生命中的非凡的时光胶囊，以及其他无数的化石树酯或琥珀样品。现年长的大卫·阿滕伯勒爵士主持了该节目，他是著名的自然主义者和电视节目主持人。正如他在展览中清楚展示的那样，他仍然沉迷于年轻时的琥珀标本以及这种材料看似神奇的品质，成为人类踏入地球之前的一个透明的窗口。巧合的是，大卫的兄弟理查德（Richard）出演了使琥珀闻名的电影：侏罗纪公园，理查德扮演一位亿万富翁企业家，他从琥珀包裹的蚊子中提取DNA，以克隆其食肉恐龙的活复制品。尽管这种情况不太可能发生，但琥珀可以以完全不同的方式重现史前生命，正如NOVA通过探查琥珀包裹的线索描绘了古代生物群落的生动图画所表明的那样。例如，世界上大多数琥珀来自波罗的海北欧地区，根据昆虫，植物碎片和其他被困物质的大量证据，大约4000万年前，一片广阔的温带森林蓬勃发展。Attenborough爵士的童年纪念品是一块波罗的海琥珀，他在格但斯克大学的生物学家Elzbieta Sontag的帮助下通过显微镜进行了调查，发现了一条长腿苍蝇，真菌，蚜虫，蚂蚁和螨虫，都是森林低层的居民。相比之下，在多米尼加共和国发现的大部分琥珀是迄今研究的第二大重要来源，大约有2000万年的历史，来自古老的雨林。俄勒冈州立大学的乔治和罗伯塔·波纳尔（George and Roberta Poinar）精心构筑了这个消失的生态系统，其依据是，a可能会栖息在一个充满水的热带凤梨中，然后与沼泽甲虫一起被倒入一片树状树脂中。最终变成琥珀色。一个更古老的多米尼加样本（距今1.5亿年前）包含一个蜜罐蚂蚁。由于这种蚂蚁现在仅在澳大利亚发现，因此该标本是曾经构成地球大部分生物的推测超大陆的证据。的大陆。高科技医疗扫描仪已经发现了许多其他的琥珀色内含物，例如诊断出壁虎折断了，这表明蜥蜴是鸟的猎物，然后被意外掉入树脂中。然而，关于琥珀的最有争议的研究是从被困生物中提取DNA的努力，就像在侏罗纪公园中一样。到目前为止，包括Poinars在内的两支球队已经宣布成功。但是，后续研究表明，两组发现的DNA都是污染物，而不是真正的古老物质。撇开挫折，科学家才刚刚开始揭示在温暖，发光，玻璃状琥珀世界中发现的秘密。被不小心掉入树脂中的猎物。然而，关于琥珀的最有争议的研究是从被困生物中提取DNA的努力，就像在侏罗纪公园中一样。到目前为止，包括Poinars在内的两支球队已经宣布成功。但是，后续研究表明，两组发现的DNA都是污染物，而不是真正的古老物质。撇开挫折，科学家才刚刚开始揭示在温暖，发光，玻璃状琥珀世界中发现的秘密。被不小心掉入树脂中的猎物。然而，关于琥珀的最有争议的研究是从被困生物中提取DNA的努力，就像在侏罗纪公园中一样。到目前为止，包括Poinars在内的两支球队已经宣布成功。但是，后续研究表明，两组发现的DNA都是污染物，而不是真正的古老物质。撇开挫折，科学家才刚刚开始揭示在温暖，发光，玻璃状琥珀世界中发现的秘密。Forty million years ago a diverse community of insects living at the bottom of a tree in a temperate forest chanced into a sticky pool of pine resin. Then a mere 67 years ago a young boy named David Attenborough was given the amber stone containing the entombed bugs. "Jewel of the Earth" explores the remarkable time capsule of ancient life preserved in this and countless other samples of fossilized tree resin, or amber.Sir David Attenborough, now grown up and a celebrated naturalist and TV personality, hosts the program. As he makes abundantly clear in the show, he is still entranced with the amber specimen from his youth and the seemingly magical quality of the material to serve as a crystal-clear window to an age before humans walked the Earth. Coincidentally, David's brother Richard starred in the movie that made amber famous: Jurassic Park, in which Richard plays a billionaire entrepreneur who extracts DNA from amber-entombed mosquitoes in order to clone living replicas of their prey—dinosaurs. While such a scenario is probably unlikely, amber can resurrect prehistoric life in a quite different way, as NOVA demonstrates by probing the amber-encased clues that paint a fascinating picture of ancient biomes.For example, most of the world's amber comes from the Baltic region of northern Europe, where, on the ample evidence of insects, plant fragments, and other trapped material, a vast temperate forest flourished about 40 million years ago. Sir Attenborough's boyhood keepsake is a piece of Baltic amber, which he investigates through a microscope with the help of biologist Elzbieta Sontag of the University of Gdansk, finding a long-legged fly, a fungus gnat, an aphid, an ant, and a mite—all denizens of the lower forest floor. By contrast, much of the amber found in the Dominican Republic—the second most significant source studied so far—is about 20 million years old and hails from an ancient rain forest. George and Roberta Poinar of Oregon State University have reconstructed this vanished ecosystem in spectacular detail, based on such clues as a tadpole that probably resided in a water-filled tropical bromeliad before being upended, along with a marsh beetle, into a patch of tree resin that eventually turned into amber.An even more ancient Dominican sample, from 150 million years ago, contains a honeypot ant. Since this ant is now found only in Australia, the specimen is evidence for a conjectured super-continent that once comprised most of Earth's landmasses. High-tech medical scanners have shed light on many other amber inclusions, diagnosing a broken back on a gecko, for instance, which suggests the lizard was a bird's prey before being accidentally dropped into resin. The most controversial research on amber, however, is the effort to extract DNA from trapped creatures, just like in Jurassic Park. So far, two teams, including the Poinars, have announced success. However, follow-up studies indicate the DNA found by both groups was a contaminant, not the real, ancient stuff. Setbacks aside, scientists have only just begun to reveal the secrets to be discovered in the warm, glowing, glassy world of amber.
