Today, with relatively easy access to our DNA ancestry, we have more data about ourselves and family history than previous generations could have imagined. In the 12 fascinating lessons of Identity in the Age of Ancestral DNA, Anita Foeman, PhD, professor of communication and media, and founder and primary investigator of the DNA Discussion Project at West Chester University, takes us behind the scenes to examine what really happens when individuals receive their personal DNA ancestry results.

One of the biggest discoveries in physics, the quest for the Higgs boson demonstrates the value of a good theory. In July 2012, a Higgs-like particle was found near the energies scientists predicted. Now, armed with better evidence and better questions, the scientific process continues. In this audiobook, we’ve gathered our best reporting to explain that process - the theories, the search, the discovery, and the ongoing questions.

In the mid-1970s, scientists began using DNA sequences to reexamine the history of all life. Perhaps the most startling discovery to come out of this new field is horizontal gene transfer (HGT), or the movement of genes across species lines. For instance, we now know that roughly eight percent of the human genome arrived not through traditional inheritance from directly ancestral forms, but sideways by viral infection - a type of HGT. In The Tangled Tree David Quammen chronicles these discoveries through the lives of the researchers who made them.

This adventure in science and imagination, which the Medical Tribune said might herald "a Copernican revolution for the life sciences", leads the listener through unexplored jungles and uncharted aspects of mind to the heart of knowledge. In a first-person narrative of scientific discovery that opens new perspectives on biology, anthropology, and the limits of rationalism, The Cosmic Serpent reveals how startlingly different the world around us appears when we open our minds to it.

The burgeoning new science of epigenetics offers a cornucopia of insights - some comforting, some frightening. For example, the male fetus may be especially vulnerable to certain common chemicals in our environment, in ways that damage not only his own sperm but also the sperm of his sons. And it’s epigenetics that causes identical twins to vary widely in their susceptibility to dementia and cancer. But here’s the good news: unlike mutations, epigenetic effects are reversible. Indeed, epigenetic engineering is the future of medicine.

Short, sassy, and bold, Mean Genes reveals that our struggles for self-improvement are, in fact, battles against our own genes - genes that helped our distant ancestors flourish, but are selfish and out of place in the modern world.

Referring to Lewis Carroll's Red Queen from Through the Looking-Glass, a character who has to keep running to stay in the same place, Matt Ridley demonstrates why sex is humanity's best strategy for outwitting its constantly mutating internal predators.

Most claims of Native American ancestry rest on the mother's ethnicity. This can be verified by a DNA test determining what type of mitochondrial DNA she passed to you. A hundred participants in DNA Consultants multi-phase Cherokee DNA Study did just that. What they had in common is they were previously rejected - by commercial firms, genealogy groups, government agencies and tribes. Their mitochondrial DNA was not classified as Native American. These are the "anomalous" Cherokee.

The Origin of Humankind is Richard Leakey's personal view of the development of Homo sapiens. At the heart of his new picture of evolution is the introduction of a heretical notion: Once the first apes walked upright, the evolution of modern humans became possible and perhaps inevitable. From this one evolutionary step comes all the other evolutionary refinements and distinctions that set the human race apart from the apes.

AudioLearn’s College Level Courses Presents Genetics. Developed by experienced professors and professionally narrated for easy listening, this course is a great way to explore the subject of college-level Genetics. The audio is focused and high-yield, covering the most important topics you might expect to learn in a typical undergraduate Genetics course. The material is accurate, up-to-date, and broken down into bite-sized sections. There are quizzes and key takeaways following each section to review questions commonly tested and drive home key points.

Why did humans abandon hunting and gathering for sedentary communities dependent on livestock and cereal grains and governed by precursors of today's states? Most people believe that plant and animal domestication allowed humans, finally, to settle down and form agricultural villages, towns, and states, which made possible civilization, law, public order, and a presumably secure way of living. But archaeological and historical evidence challenges this narrative.

The open ocean, far from the shore and miles above the seafloor, is a vast and formidable habitat that is home to the most abundant life on our planet, from giant squid and jellyfish to anglerfish with bioluminescent lures that draw prey into their toothy mouths. Into the Great Wide Ocean takes listeners inside the peculiar world of the seagoing scientists who are providing tantalizing new insights into how the animals of the open ocean solve the problems of their existence.

The Galapagos were once known to the sailors and pirates who encountered them as Las Encantadas: the enchanted islands, home to exotic creatures and dramatic volcanic scenery. In The Galapagos, science writer Henry Nicholls offers a lively natural and human history of the archipelago, charting its evolution from deserted wilderness to scientific resource (made famous by Charles Darwin) and global ecotourism hot spot.

Cooperation is the means by which life arose in the first place. It’s how we progressed through scale and complexity, from free-floating strands of genetic material, to nation states. But given what we know about the mechanisms of evolution, cooperation is also something of a puzzle. How does cooperation begin, when on a Darwinian level, all that the genes in your body care about is being passed on to the next generation? A biologist by training, Raihani looks at where and how collaborative behavior emerges throughout the animal kingdom, and what problems it solves.

Approximately 200,000 years ago, as modern humans began to radiate out from their evolutionary birthplace in Africa, Neanderthals were already thriving in Europe - descendants of a much earlier migration of the African genus Homo. But when modern humans eventually made their way to Europe 45,000 years ago, Neanderthals suddenly vanished.

There is a human genetic fluke that is surprisingly common, due to a change in a key pair of chromosomes. In the normal condition the two look the same, but in this disorder one is malformed and shrunken beyond recognition. The result is a shortened life span, higher mortality at all ages, an inability to reproduce, premature hair loss, and brain defects variously resulting in attention deficit, hyperactivity, conduct disorder, hypersexuality, and an enormous excess of both outward and self-directed aggression. It is called maleness.

Religious fundamentalists and biblical literalists present any number of arguments that attempt to disprove evolution. Those with a sympathetic ear often fail to critically examine these creationist claims, leading to an ill-informed public and, perhaps more troubling, ill-advised public policy. As Aron Ra makes clear, however, every single argument deployed by creationists in their attacks on evolution is founded on fundamental scientific, religious, and historical falsehoods - all of them.

Red is a brilliantly told, captivating history of red hair throughout the ages. An audiobook that breaks new ground, dispels myths, and reinforces the special nature of being a redhead, with a look at multiple disciplines, including science, religion, politics, feminism and sexuality, literature, and art. With an obsessive fascination that is as contagious as it is compelling, author Jacky Colliss Harvey (herself a redhead) begins her exploration of red hair in prehistory and traces the redhead gene as it made its way out of Africa with the early human diaspora.

Each of us began life as a single cell. From this humble origin, we embarked on a risky journey fraught with opportunities for disaster. Yet, amazingly, we reached our destination intact, emerging as dazzlingly complex, exquisitely engineered assemblages of trillions of cells. This metamorphosis constitutes one of nature's most spectacular yet commonplace magic tricks—and one of its most coveted secrets. In From One Cell, physician and researcher Ben Stanger offers a glimpse into what scientists are discovering about how life and the body take shape.

The study of human evolution is advancing rapidly. Newly discovered fossil evidence is adding ever more pieces to the puzzle of our past, while revolutionary technological advances in the study of ancient DNA are completely reshaping theories of early human populations and migrations. In this Very Short Introduction, Bernard Wood traces the history of paleoanthropology from its beginnings in the 18th century to the very latest fossil finds.
