Biological Anthropology

Robert Ardrey guides the listener on a remarkable journey of discovery through 20 million years of man's prehistory: from the days when his ancestors first emerged from the forests of Africa during the benevolent warmth and rains of the Miocene, through the unremitting drought of the Pliocene and the dramatic climactic shifts of the Pleistocene, down to those few thousand years past when man emerged at last onto the stage of recorded history as a fully evolved hunting animal.

From the family to the workplace to the marketplace, every facet of our lives is shaped by cooperative interactions. Yet everywhere we look, we are confronted by proof of how difficult cooperation can be - snarled traffic, polarized politics, overexploited resources, social problems that go ignored. The benefits to oneself of a free ride on the efforts of others mean that collective goals often are not met. But compared to most other species, people actually cooperate a great deal. Why is this?

Race has provided the rationale and excuse for some of the worst atrocities in human history. Yet, according to many biologists, physical anthropologists, and geneticists, there is no valid scientific justification for the concept of race. To be more precise, although there is clearly some physical basis for the variations that underlie perceptions of race, clear boundaries among "races" remain highly elusive from a purely biological standpoint.

Big Bone Lick: The Cradle of American Paleontology recounts the rich history of the fossil site that gave the world the first evidence of the extinction of several mammalian species, including the American mastodon. Big Bone Lick has played many roles: nutrient source, hallowed ground, salt mine, health spa, and a rich trove of wonders. Stanley Hedeen presents a comprehensive narrative of Big Bone Lick from its geological formation forward, explaining why the site attracted animals, regional tribespeople, European explorers and scientists, and eventually American pioneers.

Es ist eine Frage, die sich Menschen seit Tausenden von Jahren stellen: Woher kommen wir? Nach Antworten suchen Fachleute auch in unserer DNA – und hier decken sie einige Sensationen auf. Im Erbgut von Homo sapiens befinden sich nämlich Abschnitte, die gar nicht von den Ahnen unserer Spezies stammen. Neandertaler, Denisovianer und weitere, noch unbekannte Vettern der Gattung Homo haben sich offenbar mit unseren Vorfahren gepaart und so zu unserem Genom beigetragen. Und auch unsere jüngere evolutionäre Vergangenheit hat markante Spuren in unseren Genen hinterlassen.

Our species, it appears, is hardwired to get things wrong in myriad different ways. Why did recipients of a loan offer accept a higher rate of interest when a pretty woman's face was printed on the flyer? Why did one poll on immigration find the most despised aliens were ones from a group that did not exist? What made four of the Air Force's best pilots fly their planes, in formation, straight into the ground?
