Biological Age

The emerging field of evolutionary psychology remains controversial, perhaps especially among Christians. Yet according to Justin Barrett and Pamela Ebstyne King, it can be a powerful tool for understanding human nature and our distinctively human purpose. Thriving with Stone Age Minds provides an introduction to evolutionary psychology, explaining key concepts like hyper-sociality, information gathering, and self-control.

The fascinating group of animals called dinosaurs became extinct some 65 million years ago (except for their feathered descendants). In their place evolved an enormous variety of land creatures, especially mammals, which in their way were every bit as remarkable as their Mesozoic cousins. The Age of Mammals, the Cenozoic Era, has never had its Jurassic Park, but it was an amazing time in earth's history, populated by a wonderful assortment of bizarre animals. The rapid evolution of thousands of species of mammals brought forth many incredible creatures—including our own ancestors.

The Age of Living Machines describes some of the most exciting new developments and the scientists and engineers who helped create them. Virus-built batteries. Protein-based water filters. Cancer-detecting nanoparticles. Mind-reading bionic limbs. Computer-engineered crops. Together they highlight the promise of the technology revolution of the 21st century to overcome some of the greatest humanitarian, medical, and environmental challenges of our time.

Revealed for the first time in Racing for the Bomb, Groves played a crucial and decisive role in the planning, timing, and targeting of the Hiroshima and Nagasaki missions. Norris offers new insights into the complex and controversial questions surrounding the decision to drop the bomb in Japan and Groves' actions during World War II, which had a lasting imprint on the nuclear age and the Cold War that followed.

The Pleistocene is the epoch of geologic time closest to our own. It’s a time of ice ages, global migrations, and mass extinctions - of woolly rhinos, mammoths, giant ground sloths, and not least early species of Homo. It’s the world that created ours. But outside that environmental story there exists a parallel narrative that describes how our ideas about the Pleistocene have emerged.

In The Synthetic Age, Christopher Preston argues that what is most startling about this coming epoch is not only how much impact humans have had but, more important, how much deliberate shaping they will start to do. Emerging technologies promise to give us the power to take over some of Nature's most basic operations. It is not just that we are exiting the Holocene and entering the Anthropocene; it is that we are leaving behind the time in which planetary change is just the unintended consequence of unbridled industrialism.

In the new essays collected here, an interdisciplinary group of scholars asks age-old questions about the nature and well-being of humans in the context of a revolutionary new biotechnology - one that has the potential to change the genetic make-up of both existing people and future generations. Welcoming listeners who study related issues and those not yet familiar with the formal study of bioethics, the authors of these essays open up a conversation about the ethics of gene editing.

Natalie Armstrong has everything: She's smart and beautiful, has the perfect boyfriend, early acceptance to college, and a loving family. But the summer she turns 17, she finally decides to ask some unanswered questions: Who are her biological parents, and why did they give her up when she was born? These questions take her on a journey from the deep woods of Maine to the streets of New York City, from the pages of old phone books and a tattered yearbook photo to the realization that she might actually meet her biological mother face-to-face.

As at home with Galileo and his daughter in Florence as he is with Diderot in Enlightenment France, William and Alice James in fin-de-siècle Boston, or the latest research on the genome, Gerald Weissmann distills the lessons of history to guide us through our troubled age. His message is clear: "Experimental science is our defense-perhaps our best defense-against humbug and the Endarkenment."

Lee Hood did that rarest of things. He enabled scientists to see things they couldn't see before and do things they hadn't dreamed of doing. Scientists can now sequence complete human genomes in a day, setting in motion a revolution that is personalizing medicine. Hood, a son of the American West, was an unlikely candidate to transform biology. But with ferocious drive, he led a team at Caltech that developed the automated DNA sequencer, the tool that paved the way for the Human Genome Project.

James T. Bradley introduces important biological principles and the basic procedures used in biotechnology. Various ethical issues - personhood, personal identity, privacy, ethnic discrimination, distributive justice, authenticity and human nature, and the significance of mortality in the human life cycle - are presented in a clear and unbiased manner.

In Once and Future Giants, science writer Sharon Levy digs through the evidence surrounding Pleistocene large animal ("megafauna") extinction events worldwide, showing that understanding this history - and our part in it - is crucial for protecting the elephants, polar bears, and other great creatures at risk today. These surviving relatives of the Ice Age beasts now face an intensified replay of that great die-off, as our species usurps the planet's last wild places while driving a warming trend more extreme than any in mammalian history.
