本·加罗德（Ben Garrod）主持的科学纪录片，由英国广播公司（BBC）在2019年出版-英语旁白Science Documentary hosted by Ben Garrod, published by BBC in 2019- English narration
------------------------------------------------------
该系列以具有开创性的新科学，实验和来自各个学科的领先科学家为特色，揭示了人体最大器官的自然历史。皮肤是令人难以置信的多功能器官，科学仍在学习中。它已经适应了允许动物征服地球上几乎每个栖息地的问题。[编辑]??第1章的适应性Ben Garrod教授揭示了一些开创性的新科学和惊人的专业见解，他发现人类皮肤本身就是一个生态系统，是蠕形螨的宿主，这可能会重新定义我们对人类祖先的理解。他探索了可以为在截肢术上重新设计人体皮肤以使其更加坚固的新科学。他还揭示了角蛋白是一种皮肤的重要成分，它构成了我们的头发和指甲的蛋白质如何被包括穿山甲和马在内的一些动物极大地利用了。皮肤是人体最大的器官脊椎动物有着相同的基本蓝图。对表皮，真皮和皮下脂肪三层的适应使脊椎动物得以在地球上几乎每一个栖息地繁盛。??第2章移动是什么使鲨鱼具有速度感？蛇无肢如何运动？食糖滑翔机如何没有羽毛飞翔？答案全在于他们的皮肤。本·加罗德（Ben Garrod）教授揭示了皮肤如何进化的秘密，从而使动物能够解决地球上一些最重大的挑战。为此，本奔赴皇家兽医学院的专业飞行中心分析了滑翔机利用其皮瓣在高处停留的方式。他在蓝色星球水族馆（Blue Planet Aquarium）和鲨鱼一起潜水，发现鲨鱼皮不仅很光滑，而且非常粗糙。它覆盖着成千上万的细小牙齿，使鲨鱼具有流体动力。Ben还发现了蛇腹部上的角质化鳞片是完美的配置，使它们几乎可以在遇到的任何表面上移动。??Ch3保护长颈鹿如何保持凉爽？哪些豪猪羽毛笔教会我们有关医学的知识？是什么使某些人比其他人更容易被蚊子叮咬？所有答案以及更多答案都在于皮肤如何保护我们免受敌对世界的秘密。在保护我们娇嫩的内部时，皮肤就像外衣一样。动物已经采取了各种保护自己免受敌对行星撞击的一切方法，河马生产了自己的防晒霜以保护自己免受来自太阳的紫外线的危害。直到最近，科学才发现了长颈鹿斑点背后的真相，长颈鹿斑点是一种血管网络，它们可以用来在非洲大草原的炽热中降温。本·加罗德教授发现了这一点。他通过将自己陷入深冷的冰箱中来演示人类皮肤的隔热性不足以应对极端寒冷，从而测试了人类皮肤的局限性。当他与皮肤上生长的物质面对面时，他发现人类皮肤是一个完整的虫子和细菌生态系统。当他得知携带疾病的昆虫已经进化为刺穿从人类皮肤到马皮的所有东西时，他就被蚊子和苍蝇咬了。[编辑]??第四章通讯Featuring groundbreaking new science, experiments and leading scientists from a variety of disciplines, the series unravels the natural history of the body's largest organ. Skin is an incredible, multi-function organ that science is still learning so much about. It has adapted to allow animals to conquer virtually every habitat on the planet.[edit] Ch1 Adaptability Professor Ben Garrod reveals some ground-breaking new science and amazing, specialist, factual insight as he discovers how human skin is an ecosystem in its own right, playing host to demodex mites, that might redefine our understanding of human ancestry. He explores the new science that could pave the way for re-engineering human skin on amputations to make it more robust. And he reveals how keratin, a protein that is a key component of skin and that makes up our hair and nails, has been taken to the extreme by some animals including pangolins and horses.Skin is the body’s largest organ and all vertebrates share the same basic blue print. Adaptations in the three main layers, the epidermis, the dermis and the subcutaneous fat layers have allowed vertebrates to thrive in virtually every habitat on earth.[edit] Ch2 Moving What makes sharks built for speed? How do snakes move without limbs? How do sugar gliders fly without feathers? The answer all lies in their skin.Professor Ben Garrod uncovers the secrets of how skin has evolved to enable animals to solve some of the most remarkable challenges on earth. To do this, Ben heads to the specialist flight centre at the Royal Veterinary College to analyse the way a sugar glider uses its skin flaps to stay aloft. He goes diving with sharks at the Blue Planet Aquarium and discovers that, far from being smooth, sharkskin is incredibly rough. It is covered with thousands of tiny teeth that make a shark hydrodynamic. Ben also finds out how the keratinised scales on snakes' bellies are the perfect configuration to allow them to move over virtually any surface they encounter. Amongst many other wonders of how skin has had an impact on nature.[edit] Ch3 Protection How does a giraffe stay cool? What are different porcupine quills teaching us about medicine? What makes some people more likely to be bitten by mosquitoes than others? All the answers and more lie in the secrets of how skin protects us from a hostile world. When it comes to protecting our delicate insides, skin is like an external suit of armour. Animals have adapted ways of protecting themselves from everything a hostile planet has to throw at them.Hippos produce their own sunscreen to protect themselves against the dangers of UV rays from the sun. Only recently discovered by science, is the truth behind a giraffe’s spots, a network of blood vessels that they use to cool themselves down in the blazing heat of the African savannah.Professor Ben Garrod discovers how. He tests the limitations of human skin by plunging himself into a deep freezer to demonstrate how human skin just isn’t well insulated enough to cope with extreme cold. He discovers how human skin is an entire ecosystem for bugs and bacteria as he comes face to face with what is growing on his skin. And he gets bitten by mosquitoes and stable flies as he learns that disease-carrying insects have evolved to pierce everything from human skin to horse hide.[edit] Ch4 Communication Why are male mandrill faces (big bold primates from West Africa) red and blue? How are birds' feathers so colourful? What do ringtail lemurs do to talk to one another? Their skin holds the key. As Professor Ben Garrod explores how animals communicate with one another, he uncovers a myriad more wonderful ways.Skin has evolved in some remarkable ways to enable animals to communicate with each other, from vibrant displays of colour to skin pouches to amplify sound. Ben shows how animals have evolved to use skin to make themselves heard loud and clear. Birds are notable for their use of coloured feathers to attract mates, show status and as displays of aggression. But, as Ben discovers, long before birds evolved their unrivalled use of colour, it is now believed that their ancestors, the dinosaurs, could well have been using colour to communicate. Ben also uncovers how one species of fish communicates using electricity, and a common British bird has been secretly communicating for years, without us ever knowing.[edit] Ch5 Defence What is the most toxic animal on earth? How are porcupine quills helping us in medicine? Why is a rhino armour plated, and it is not to protect them from lions?Professor Ben Garrod discovers the complex ways, from camouflage to deadly toxins, in which the skin helps defend animals against threats of all kinds. From the barbed quills of the North American porcupine to the battering ram of a rhino’s horn, the skin has developed an impressive armoury of weapons and warnings to keep predators at bay.With experiments and specialist factual insight, Professor Ben Garrod reveals the toughest and most resilient of animals defend themselves through their skin. One of the most iconic warnings in nature is that of the rattlesnake. Ben takes a teaching sample of a rattlesnake’s tail to the University of Bristol to test just how fast it can vibrate. He uncovers how poison-dart frogs produce their toxins, and how cuttlefish are the masters of disguise when it comes to hiding in plain sight.[edit] Ch6 Sensing Professor Ben Garrod explores how some snakes can see using heat, how crocodiles feel through their jaws and how some animals use electricity to navigate their world - and it is all only possible because of remarkable adaptations to their skin.Whether animals live on land, in the sea, or in subterranean communities, skin is critical in allowing them to sense the world around them, be it to find food, navigate harsh environments or avoid danger. Even the toughest of animals, crocodilians, have a surprisingly sensitive side when it comes to the specialised skin sensors they use to detect the tiniest of ripples in the water. Deadly pit vipers use heat sensors to ambush the small rodents they feed on. Professor Ben Garrod puts them to the test with an experiment to see if they will strike a cold or warm ping-pong ball. He also uncovers how the less-than-attractive leaf-nosed bat puts its facial skin to good use as an acoustic lens to echolocate around its dense forest habitat.
