For most of us, the story of mammal evolution starts after the asteroid impact that killed the dinosaurs, but over the last 20 years, scientists have uncovered new fossils and used new technologies that have upended this story. In Beasts Before Us, paleontologist Elsa Panciroli charts the emergence of the mammal lineage, Synapsida, beginning at their murky split from the reptiles in the Carboniferous period, over 300 million years ago. They made the world theirs long before the rise of dinosaurs.

A story of defiance and determination by a controversial scientist, this is Lee Berger's own take on finding Homo naledi, an all-new species on the human family tree and one of the greatest discoveries of the 21st century. In 2013, Lee Berger, a National Geographic explorer-in-residence, heard of a cache of bones in a hard-to-reach underground cave in South Africa. He put out a call around the world for petite collaborators - men and women small and adventurous enough to be able to squeeze through eight-inch tunnels to reach a sunless cave forty feet underground. It worked.

A moving, inspiring, personal look at the vastly changing world of wildlife on planet earth as a result of human incursion, and the crucial work of animal and bird preservation across the globe being done by scientists, field biologists, zoologists, environmentalists, and conservationists.

Every time Bill Bryson walks out the door, memorable travel literature threatens to break out. His previous excursion on the Appalachian Trail resulted in the best seller A Walk in the Woods. Now, we follow him "Down Under" to Australia with this delectably funny, fact-filled, and adventurous performance that combines humor, wonder, and unflagging curiosity. More from Bill Bryson.

A major audiobook about the future of the world, blending intellectual and natural history and field reporting into a powerful account of the mass extinction unfolding before our eyes. Over the last half a billion years, there have been five mass extinctions, when the diversity of life on Earth suddenly and dramatically contracted. Scientists around the world are currently monitoring the sixth extinction, predicted to be the most devastating extinction event since the asteroid impact that wiped out the dinosaurs.

From the irrepressible author of Trout Bum and The View from Rat Lake comes an engaging, humorous, often profound examination of life's greatest mysteries: sex, death, and fly-fishing. John Gierach's quest takes us from his quiet home water (an ordinary, run-of-the-mill trout stream where fly-fishing can be a casual affair) to Utah's famous Green River, and to unknown creeks throughout the Western states and Canada. We're introduced to a lively group of fishing buddies, some local "experts," and even an ex-girlfriend, along the way.

It was the winter of 1902; South African park ranger Harry Wolhuter was on horseback, patrolling the area for poachers at Kruger National Park. Little did he know, he was also being stalked. Out of nowhere, two huge male lions pounced on Harry's horse, knocking the man to the ground. The horse ran off, leaving Harry to fend for himself. One of the lions lunged at him - piercing deep into his flesh and bones - and began to drag him far into the jungle to finish him off.

An enthralling account of a modern voyage of discovery as we meet the clever, social birds of prey called caracaras, which puzzled Darwin, fascinate modern-day falconers, and carry secrets of our planet's deep past in their family history.

Elegantly told against a haunting melodic backdrop, Crossing Open Ground's brilliant descriptions will sweep you into a new perspective - the land both gives us strength and molds our souls.

In Eager, environmental journalist Ben Goldfarb reveals that our modern idea of what a healthy landscape looks like and how it functions is wrong, distorted by the fur trade that once trapped out millions of beavers from North America's lakes and rivers. The consequences of losing beavers were profound: streams eroded, wetlands dried up, and species from salmon to swans lost vital habitat. Today, a growing coalition of "Beaver Believers" recognizes that ecosystems with beavers are far healthier, for humans and non-humans alike, than those without them.

Half of all species could disappear by the end of the century, and scientists now concede that most of America’s endangered animals will survive only if conservationists keep rigging the world around them in their favor. So Jon Mooallem ventures into the field, often taking his daughter with him, to move beyond childlike fascination and make those creatures feel more real. Wild Ones is a tour through our environmental moment and the eccentric cultural history of people and wild animals in America that inflects it.

This is the inspiring story of an ordinary guy who achieved two great goals that others had told him were impossible. First, he set a record for the longest automobile journey ever made around the world, during the course of which he blasted his way out of minefields, survived a breakdown atop the Peak of Death, came within seconds of being lynched in Pakistan, and lost three of the five men who started with him - two to disease, one to the Vietcong.

New York Times bestselling author Jim Harrison (1937-2016) was a writer with a poet’s economy of style and trencherman’s appetites and ribald humor. In The Search for the Genuine, a collection of new and previously published essays, the giant of letters muses on everything from grouse hunting and fishing to Zen Buddhism and matters of the spirit, including reported pieces on Yellowstone and shark-tagging in the open ocean, commentary on writers from Bukowski to Neruda to Peter Matthiessen, and a heartbreaking essay on life on the US/Mexico border.

One of the most brilliant biologists of our time, and a charismatic daredevil, Dr. Joe Slowinski had been obsessed with venomous snakes since his youth. In 2001 Slowinski led a team of young scientists deep into the wilds of Burma on a final tragic expedition. Immediately after being bitten by the many-banded krait, the deadliest serpent in Asia, Joe knew his life was in grave and imminent peril.

Early in 2013 Neil Hayward was at a crossroads. He didn't want to open a bakery or whatever else executives do when they quit a lucrative but unfulfilling job. He didn't want to think about his failed relationship with 'the one' or his potential for ruining a new relationship with 'the next one'. And he almost certainly didn't want to think about turning 40. And so instead he went birding. Birding was a lifelong passion. It was only among the birds that Neil found a calm that had eluded him in the confusing world of humans.
