Peter S. Ungar is Distinguished Professor and director of the Environmental Dynamics Program at the University of Arkansas. He is the author of Teeth: A Very Short Introduction and Mammal Teeth: Origin, Evolution, and Diversity and the editor of Evolution of the Human Diet: The Known, the Unknown, and the Unknowable. He lives in Fayetteville, Arkansas.
Whether we realize it or not, we carry in our mouths the legacy of our evolution. Our teeth are like living fossils that can be studied and compared to those of our ancestors to teach us how we became human. In Evolution's Bite, noted paleoanthropologist Peter Ungar brings together for the first time cutting-edge advances in understanding human evolution and climate change with new approaches to uncovering dietary clues from fossil teeth to present a remarkable investigation into the ways that teeth—their shape, chemistry, and wear—reveal how we came to be.
Ungar describes how a tooth's "foodprints"—distinctive patterns of microscopic wear and tear—provide telltale details about what an animal actually ate in the past. These clues, combined with groundbreaking research in paleoclimatology, demonstrate how a changing climate altered the food options available to our ancestors, what Ungar calls the biospheric buffet. When diets change, species change, and Ungar traces how diet and an unpredictable climate determined who among our ancestors was winnowed out and who survived, as well as why we transitioned from the role of forager to farmer. By sifting through the evidence—and the scars on our teeth—Ungar makes the important case for what might or might not be the most natural diet for humans.
Traveling the four corners of the globe and combining scientific breakthroughs with vivid narrative, Evolution's Bite presents a unique dental perspective on our astonishing human development.
看见这本书的书名就知道这本书所围绕的中心是牙齿。作者以牙齿为出发点,比较灵长类动物,哺乳动物的牙齿的不同,食肉动物与食草动物牙齿的不同。来解密人的牙齿的变化。 这本书不简单的把一些研究材料人物的精选编排。来推算人类的发展,以及周围环境气候与科技进步对牙齿的影...
評分这本书吧,说它有趣,它又没那么有趣,说它无聊吧,表达起来也算生动,反正我没有那么喜欢,算一本中等的科普读物吧。 这本书的描写主要分成两个部分,一部分是对于牙齿的描写分析,另一部分则是寻找牙齿碎片的经历,更大程度上对后一部分的描写超过了前一部分描写,结合历史更...
評分感谢豆瓣鉴书团让我得以接触这本科普读物,否则以我贫瘠的阅读能力可能就与这本书终生无缘了。 作者以丰富有趣的笔触将牙齿研究的历史和过程娓娓道来,对于自然环境的描写能够呈现出清晰的画面感,仿若观赏纪录片一样直观。不知是什么缘故,感觉自己对于文字有一些片面的认知,...
