Genetic Anthropology

When you think of evolution, the picture that most likely comes to mind is a straight-forward progression, the iconic illustration of a primate morphing into a proud, upright human being. But in reality, random events have played huge roles in determining the evolutionary histories of everything from lions to lobsters to humans. However, random genetic novelties are most likely to become fixed in small populations. It is mathematically unlikely that this will happen in large ones.

For all that science knows about the living world, notes David P. Barash, there are even more things we don't know, genuine evolutionary mysteries that perplex the best minds in biology. Paradoxically, many of these mysteries are very close to home, involving some of the most personal aspects of being human. Homo Mysterious examines a number of these evolutionary mysteries, exploring things we don't yet know about ourselves, laying out the best current hypotheses, and pointing toward insights that scientists are just beginning to glimpse.

Violation of biological command has been the failure of social man. Vertebrates though we may be, we have ignored the law of equal opportunity since civilization's earliest hours. Sexually reproducing beings though we are, we pretend today that the law of inequality does not exist. And enlightened though we may be, while we pursue the unattainable we make impossible the realizable.

Il y a environ 4 000 millions d'années, la vie est apparue sur la Terre. Mais quelle est l'histoire de son évolution ? La vie était-elle inévitable ? La race humaine, telle que nous la connaissons, était-elle prévisible ? Quels autres êtres intelligents auraient pu la remplacer ? À partir de questionnements comme ceux-ci et des réponses scientifiques qui existent déjà, Juan Luis Arsuaga nous présente les découvertes-clés de la théorie de l'évolution et nous élève vers un questionnement plus vaste encore : pourquoi sommes-nous ici ?

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.

Humans now live longer and better than ever before, and we are the most populous big animal on earth. Meanwhile, our closest living relatives, the now-endangered chimpanzees, continue to live as they have for millions of years. We are not like the other animals, yet we evolved through the same process. What are we, then? And now we have remade the world, what are we becoming? Setting out to answer this question, Gaia Vince tells a remarkable evolution story about us.

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?

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.

Una storia prima della storia. Ossa fossili, denti, manufatti, siti preistorici e dati genetici per ricostruire l'evoluzione di un gruppo di scimmie antropomorfe che, intorno a 6 milioni di anni fa, in Africa, intrapresero l'intricato percorso evolutivo che diede origine alla nostra specie.

The world is a giant experimental lab for the GMO chemists. They have bought the elected representatives who have allowed them to write laws to benefit themselves and no one else. They ban independent scientific research because they know the negative outcomes. They have sued farmers who planted non-GMO crops that were damaged by GMO crops nearby. They have cost the farmers of America millions of dollars, if not billions, in foreign sales.
