What teeth can teach us about the evolution of the human species 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.

By focusing on the cellular mechanisms that underlie ontogeny, phylogeny and regeneration of complex physiologic traits, Evolution, the Logic of Biology demonstrates the use of homeostasis, the fundamental principle of physiology and medicine, as the unifying mechanism for evolution as all of biology. The homeostasis principle can be used to understand how environmental stressors have affected physiologic mechanisms to generate condition-specific novelty through cellular mechanisms. Evolution, the Logic of Biology allows the reader to understand the vertebrate life-cycle as an intergenerational continuum in support of effective, on-going environmental adaptation. By understanding the principles of physiology from their fundamental unicellular origins, culminating in modern-day metazoans, the reader as student, researcher or practitioner will be encouraged to think in terms of the prevention of disease, rather than in the treatment of disease as the eradication of symptoms. By tracing the ontogeny and phylogeny of this and other phenotypic homologies, one can perceive and understand how complex physiologic traits have mechanistically evolved from their simpler ancestral and developmental origins as cellular structures and functions, providing a logic of biology for the first time. Evolution, the Logic of Biology will be an invaluable resource for graduate students and researchers studying evolutionary development, medicine and biology, anthropology, comparative and developmental biology, genetics and genomics, and physiology.

Food is not only something we eat, it is something we use to define ourselves. Ingestion and incorporation are central to our connection with the world outside our bodies. Food's powerful social, economic, political and symbolic roles cannot be ignored - what we eat is a marker of power, cultural capital, class, ethnic and racial identity. Bite Me considers the ways in which popular culture reveals our relationship with food and our own bodies and how these have become an arena for political and ideological battles. Drawing on an extraordinary range of material - films, books, comics, songs, music videos, websites, slang, performances, advertising and mass-produced objects - Bite Me invites the reader to take a fresh look at today's products and practices to see how much food shapes our lives, perceptions and identities.

Today's consumers have unprecedented choice in terms of the technologies and platforms that access, produce, and distribute media content. The development and overlap of television, the internet, and other media technologies is fragmenting and empowering media audiences more than ever. Building on his award-winning book, Audience Economics, Philip M. Napoli maps the landscape of our current media environment and describes its challenge to traditional conceptions of the audience. He examines the redefinition of the industry-audience relationship by technologies that have moved the audience marketplace beyond traditional metrics. Media providers, advertisers, and audience measurement firms now deploy more sophisticated tools to gather and analyze audience information, focusing on factors rarely considered before, such as appreciation, recall, engagement, and behavior. Napoli explores the interplay between political and economic interests in the audience marketplace and their effect on audience evolution. He recounts the battles waged between stakeholders over the assessment of media audiences and their efforts to restrict the functionality of new technologies. As Napoli makes clear, the very meaning of the media audience continues to evolve in response to changing technological, economic, and political conditions.

Vom angry young man zum Ausnahme-Unternehmer Halb Genie, halb Wahnsinniger, Guru, Choleriker und Kontrollfreak – das ist das vorherrschende Bild, das sich die Welt von Steve Jobs gemacht hat. Jobs selbst hat zu seinen Lebzeiten dieses Image gern gepflegt, und seine Biographen sind ihm bereitwillig gefolgt. Vier Jahre nach seinem Tod im Oktober 2011 ist es nun an der Zeit, ein klareres Bild des Apple-Gründers zu zeichnen, ein Bild, das frei ist von Klischees und Vorurteilen. Brent Schlender begleitete Steve Jobs über zwanzig Jahre lang, der engen Freundschaft der beiden verdanken wir tiefe Einblicke in das Leben des Unternehmers und in das Imperium von Apple. Auf Grundlage zahlreicher Gespräche mit Jobs selbst, mit engsten Vertrauten und Weggefährten wie Tim Cook oder auch Bill Gates ist ein ebenso differenziertes wie leidenschaftliches Porträt entstanden, das in seinem Kern der Frage nachgeht, wie aus einem ungestümen jungen Gründer die wichtigste Unternehmerpersönlichkeit unserer Zeit reifen konnte. Die Nähe Schlenders und das Knowhow Tetzelis – beide gehören zu den profiliertesten Technikjournalisten und zu den besten Kennern der Silicon-Valley-Szene – machen Becoming Steve Jobs zu einer mitreißenden Geschichte der Technologie-Ära und zu einer Biographie, die den Unternehmer nicht zur Ikone erhebt, sondern den Menschen hinter dem Mythos zum Vorschein bringt.

Mögen Sie Rosenkohl? Lieben Sie Brokkoli? Oder ist Fleisch Ihr Gemüse? Dass die Geschmäcker verschieden sind, ist eine Binsenweisheit. Aber nirgendwo sind die Vorlieben und Abneigungen so ausgeprägt wie beim Essen und so immun gegen gute Argumente. Nicht nur Eltern wissen davon ein Lied zu singen. Warum ist das so? Und was können wir tun, um anders, besser, zu essen? Bee Wilson hat sich auf eine spannende Reise zu den Ursprüngen unserer Ernährungsgewohnheiten begeben, mit der neuesten Forschungsliteratur sowie ihren eigenen Erfahrungen als Mutter von drei Kindern im Gepäck. Sie hat mit Psychologen und Ernährungsexperten gesprochen, Schulkantinen besucht und zahlreiche »Essbiographien« zusammengetragen. Das Ergebnis ist so lehrreich wie ermutigend: Geschmack ist kein Schicksal. Welche Speisen wir mögen, ob wir essen wie ein Spatz oder wie ein Scheunendrescher, ist uns nicht in die Wiege gelegt. Wir lernen es, und zwar in der Kindheit, am Esstisch der Familie, unter Einfluss zahlreicher Faktoren. Und wir können umlernen. Bee Wilson zeigt uns in ihrem neuen Buch, wie das geht, ohne dabei aus den Augen zu verlieren, was vielleicht das Wichtigste ist: die Freude am Essen.

What the Fossils Say and Why It Matters

Over the past twenty years, paleontologists have made tremendous fossil discoveries, including fossils that mark the growth of whales, manatees, and seals from land mammals and the origins of elephants, horses, and rhinos. Today there exists an amazing diversity of fossil humans, suggesting we walked upright long before we acquired large brains, and new evidence from molecules that enable scientists to decipher the tree of life as never before. The fossil record is now one of the strongest lines of evidence for evolution. In this engaging and richly illustrated book, Donald R. Prothero weaves an entertaining though intellectually rigorous history out of the transitional forms and series that dot the fossil record. Beginning with a brief discussion of the nature of science and the "monkey business of creationism," Prothero tackles subjects ranging from flood geology and rock dating to neo-Darwinism and macroevolution. He covers the ingredients of the primordial soup, the effects of communal living, invertebrate transitions, the development of the backbone, the reign of the dinosaurs, the mammalian explosion, and the leap from chimpanzee to human. Prothero pays particular attention to the recent discovery of "missing links" that complete the fossil timeline and details the debate between biologists over the mechanisms driving the evolutionary process. Evolution is an absorbing combination of firsthand observation, scientific discovery, and trenchant analysis. With the teaching of evolution still an issue, there couldn't be a better moment for a book clarifying the nature and value of fossil evidence. Widely recognized as a leading expert in his field, Prothero demonstrates that the transformation of life on this planet is far more awe inspiring than the narrow view of extremists.

Evolution and Senses

Opsins, Bitter Taste, and Olfaction

This book focuses on sensing and the evolution of animals. Using the five senses (visual, auditory, and olfactory perception, and taste and touch), animals can receive environmental stimuli and respond to them. Changes in these sensitivities might cause changes in aspects of animals’ lives such as habitat, activity timing, and diet—and vice versa. Recent advances in genome and molecular analysis enable us to investigate certain changes in the receptors or mechanisms involved in sensing and provide clues for understanding the evolution of animals related to those changes. The first chapter deals with the molecular evolution of opsins. In addition to the well-known function of opsins as visual receptors, opsins can be related to non-visual photoreception such as photoentrainment of circadian rhythm, photoperiodism, and background adaptation. Molecular phylogenic studies reveal that all opsin genes have evolved from one ancient opsin gene. The evaluation of the functions of each extant opsin protein based on the molecular features enables us to predict the molecular evolution and diversification of opsins during the evolution of animals. These studies shed light on which amino-acid substitutions cause the functional diversification of opsins and how they have influenced the evolution of animals. The second chapter has to do with bitter taste perception, a key detection mechanism against the ingestion of bioactive substances. Genetic and behavioral evidence reveal the existence of "non-taster" Japanese macaques for specific bitter compounds, which originated in a restricted region of Japan. This finding might provide a clue for elucidating the ecological, evolutionary, and neurobiological aspects of bitter taste perception of primates. The third chapter presents an extreme example of the evolution of olfaction, namely, that fully aquatic amniotes have generally reduced their olfactory capacity considerably compared to their terrestrial relatives. Interestingly, the remaining olfactory abilities are quite different among three fully aquatic amniotes investigated: toothed whales have no nervous system structures that mediate olfaction, but baleen whales can smell in air, and it has been suggested that sea snakes smell underwater.
