Genetic Anthropology

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.

An entertaining and enlightening exploration of why waste matters, this cultural history explores an often ignored subject matter and makes a compelling argument for a deeper understanding of human and animal waste. Approaching the subject from a variety of perspectives - evolutionary, ecological, and cultural - this examination shows how integral excrement is to biodiversity, agriculture, public health, food production and distribution, and global ecosystems.

Pets have never been more popular. Over half of American households share their home with either a cat or a dog, and many contain both. This is a huge change from only a century ago, when the majority of domestic cats and dogs were working animals, keeping rodents at bay, guarding property, herding sheep. Nowadays, most are valued solely for the companionship they provide. As mankind becomes progressively more urban and detached from nature, we seem to be clinging to the animals that served us well in the past.

When did the human species turn against the planet that we depend on for survival? Human industry and consumption of resources have altered the climate, polluted the water and soil, destroyed ecosystems, and rendered many species extinct, vastly increasing the likelihood of an ecological catastrophe. How did humankind come to rule nature to such an extent? To regard the planet's resources and creatures as ours for the taking? To find ourselves on a seemingly relentless path toward ecocide?

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.

A new gene editing technology, invented just seven years ago, has turned humanity into gods. Enabling us to manipulate the genes in virtually any organism with exquisite precision, CRISPR has given scientists a degree of control that was undreamt of even in science fiction. But CRISPR is just the latest, giant leap in a long journey to master genetics. The Genetic Age shows the astonishing, world-changing potential of the new genetics and the possible threats it poses, sifting between fantasy and the reality when it comes to both benefits and dangers.

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?

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.

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.

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.
