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.
几万年前的人类生活究竟是亚当夏娃或是茹毛饮血,若是光靠想象不免单薄。古生物学家就像福尔摩斯,从史前痕迹中寻找人类祖先的蛛丝马迹。乔治·居维叶曾经有言:“给我看看你的牙齿,我便能知道你的身份。”古生物学家更厉害,看看原始人的牙齿,不仅能知道原始人吃什么,还能...

評分将近300万年的人类进化史,挖掘的古人类身体各部位化石最多的肯定是牙齿化石,所以拿到书以前我以为是一本通过牙齿形态变化讲述进化史的科普书。其实不是,这是一本很难用简单的语言表达出中心内容的书。 这本书几乎涵盖了上个世纪重要的古人类学理论的产生和发展,重要考古学...
評分非常幸运得到豆瓣团的青睐,让我看到新鲜滚热辣的科普类读物。 自然科学读物的魅力在于让我们更了解大自然,或者这个我们身处的世界,这本书也不例外。牙齿作为化石,成为研究人类进化史的一个载体。作者通过讲述许多小故事,包括许多科学家的有趣轶事,列举一些动物与植物之间...
