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.
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.
想读《进化的咬痕》,是因为之前读《人类简史》《人体的故事》,尤其是利伯曼的《人体的故事》,提到牙齿与进化时的故事是极为有趣的。说现代人之所以长智齿时会疼,或者长歪,是因为人在长期进化中,食物越来越精细,下巴变小了。小脸美女虽然符合审美,但难言之隐,恐怕也没...

评分 评分 评分拿到书的时候就觉得装帧很有意思 书面上有一个凹进去的齿痕 正符合了题目:进化的咬痕 因为最近有晚上咬牙的毛病 最近其实没少折腾牙齿 也因此跟一个牙医朋友熟络起来 跟他谈起这本书 其实对于普通大众(比如我)书中的一些通过牙齿看进化的历程的观点很新颖 在学术界却早已是...
