What kind of bird is unable to fold its wings? Ostrich, penguin, condor, pelican. The penguin's wings are more like flippers that help it swim through the water but they don't fold.

以下哪种鸟类不能折叠翅膀？鸵鸟，企鹅，秃鹰，还是鹈鹕？企鹅的翅膀更像鳍状肢，可帮助其在水中游泳，但不能折叠。

New research has yielded a new theory about penguins. For years, scientists have said the animals originated in Antarctica. Researchers at the University of California Berkley say penguins first came on the scene in Australia and New Zealand. Scientists teamed up with international museums and universities to look at blood and tissue samples from 18 different penguin species. From this, they suggested that the ancestors of modern-day penguins first occupied tempered environments which can have warm summers in addition to cold winters. The research proposed that the predecessors of today's King and Emperor penguins split off from the rest in pursuit of the abundant food supply of Antarctic waters. Today, different species of penguins can be found in very different environments, from the frigid polar landscape of Antarctica to the tropical region of the Galapagos Islands. And the study says how they got to such different places is still controversial.

新研究提出了有关企鹅的新理论。多年来，科学家一直认为企鹅起源于南极洲。加州大学伯克利分校的研究人员表示，企鹅最早出现在澳大利亚和新西兰。科学家与世界各地的博物馆和大学合作，研究了18个企鹅物种的血液和组织样本。他们由此得出结论称，现代企鹅的祖先最先生活在温和的环境中，这一环境既有温暖的夏季也有寒冷的冬季。研究表明，为了追求南极水域丰富的食物供应，如今的国王企鹅和帝企鹅的祖先从其他企鹅种群中分裂出来。现在，不同种类的企鹅生活在不同的环境中，从南极寒冷的极地景观至加拉帕戈斯群岛的热带地区。研究指出，至于它们是如何到达如此不同的地方的，尚未有定论。
