Birds (class Aves) are a group of endothermic vertebrates, characterised by feathers, a beak with no teeth, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a lightweight but strong skeleton. Birds live worldwide and range in size from the 5 cm (2 in) bee hummingbird to the 2.75 m (9 ft) ostrich. They rank as the class of tetrapods with the most living species, at approximately ten thousand, with more than half of these being passerines, sometimes known as perching birds or, less accurately, as songbirds.
The fossil record indicates that birds are the last surviving dinosaurs, having evolved from feathered ancestors within the theropod group of saurischian dinosaurs. True birds first appeared during the Cretaceous period, around 100 million years ago, and the last common ancestor is estimated to have lived about 95 million years ago. DNA-based evidence finds that birds radiated extensively around the time of the Cretaceous–Paleogene extinction event that killed off the non-avian dinosaurs. Birds in South America survived this event and then migrated to other parts of the world via multiple land bridges while diversifying during periods of global cooling. Primitive bird-like "stem-birds" that lie outside class Aves proper, in the group Avialae, have been found dating back to the mid-Jurassic period. Many of these early stem-birds, such as Archaeopteryx, were not yet capable of fully powered flight, and many retained primitive characteristics like toothy jaws in place of beaks and long bony tails.
Music is an art form and cultural activity whose medium is sound and silence. The common elements of music are pitch (which governs melody and harmony), rhythm (and its associated concepts tempo, meter, and articulation), dynamics (loudness and softness), and the sonic qualities of timbre and texture (which are sometimes termed the "color" of a musical sound). Different styles or types of music may emphasize, de-emphasize or omit some of these elements. Music is performed with a vast range of instruments and with vocal techniques ranging from singing to rapping, and there are solely instrumental pieces, solely vocal pieces and pieces that combine singing and instruments. The word derives from Greek μουσική (mousike; "art of the Muses"). In its most general form, the activities describing music as an art form include the production of works of music (songs, tunes, symphonies, and so on), the criticism of music, the study of the history of music, and the aesthetic examination of music. Ancient Greek and Indian philosophers defined music as tones ordered horizontally as melodies and vertically as harmonies. Common sayings such as "the harmony of the spheres" and "it is music to my ears" point to the notion that music is often ordered and pleasant to listen to. However, 20th-century composer John Cage thought that any sound can be music, saying, for example, "There is no noise, only sound."
Carl Zimmer (born 1966) is a popular science writer and blogger, especially regarding the study of evolution and parasites. He has written several books and contributes science essays to publications such as The New York Times, Discover, and National Geographic. He is a fellow at Yale University's Morse College.
Besides his popular science writing, Zimmer also gives frequent lectures, and has appeared on many radio shows, including National Public Radio's Radiolab, Fresh Air and This American Life. He has won many awards, including the 2007 National Academies Communication Award, a prize for science communication from the United States National Academy of Sciences, for his wide-ranging coverage of biology and evolution in newspapers, magazines and his blog. In 2009 and 2010 he was host of the periodic audio podcast Meet the Scientist of the American Society for Microbiology (replacing Merry Buckley).
Zimmer received his B.A. in English from Yale University in 1987. In 1989, Zimmer started at Discover magazine, first as a copy editor and fact checker, eventually becoming a contributing editor.

View full lesson: http://ed.ted.com/lessons/how-did-feathers-evolve-carl-zimmer To look at the evolution of modern bird feathers, we must start a long time ago, with the dinosaurs from whence they came. We see early incarnations of feathers on dinosaur fossils, and remnants of dinosaurs in a bird's wish bone. Carl Zimmer explores the stages of evolution and how even the reasons for feathers have evolved over millions of years. Lesson by Carl Zimmer, animation by Armella Leung.
被災された方々の傷が早く癒えますよう心からのお見舞いを申し上げます。 民間でチャリティー活動をしてくれた台湾や一般に貧しいと思われていた国々から、私たちは、失っていた大切なものをいただいたような気がします。それは、取りも直さず先人たちの警告なのかもしれません。いま、私たちの在り方が問われています。これは、いかなる武器よりも怖いことかもしれません。 音楽はPeter Bird氏によって2011年に東日本大震災の被災者に捧げるため作曲されました。Peter Bird氏はUCLAの教授で地球物理学を研究しているそうです。以下のサイトでこの曲の楽譜を公開しています。 http://peterbird.name/choral/ イラストはピアプロに寄せられた東日本大震災に関連するものより選びました。他にも素晴らしいイラストがたくさんありますので、ぜひ覗いてみてください。 http://piapro.jp/ 使わせて頂いたイラスト: 「山川に」 なんぴぃ様 『地震』 449様 『地震大丈夫ですか?』 イワチグ様 『願い』 0-Ko様 『願う』 やむあむ様 『Pray for ...』 マルセーユ←元syogyou様 『祈るミクさん。』 姫野亜樹様 『お祈りミクちゃん』 「風をいたみ」 ぴーたー様 『歌うことしか出来ないけれど』 きいろ様 『彩り』 せんと★えるも様 『せめて、心だけでも』 「わたの原」 子萩様 『届け』 イヴファーリア様 『諦めないで』 Leia様 『私の出番だねッ!!』 海兎(SK-N)様 『ファイト!』 amili様 『笑って』 k@停滞中様 『スマイル♪』 東城様 『日本頑張って』 如月弥生様 『頑張れ』 「瀬をはやみ」 はるわかめ様 『3.11』 抹茶屋様 『がんばろう東北!!』 豆吉様 『0311』 「立ち別れ」 謎。様 『あれから2年...
