Comparing gene sequences, examining atomic structures of proteins, and looking into the geochemistry of rocks have helped explain evolution in more detail than ever before. Nick Lane expertly reconstructs the history of life by describing the ten greatest inventions of evolution (including DNA, photosynthesis, sex, and sight), based on their historical impact, role in organisms today, and relevance to current controversies. Who would have guessed that eyes started off as light-sensitive spots used to calibrate photosynthesis in algae? Or that DNA’s building blocks form spontaneously in hydrothermal vents? Lane gives a gripping, lucid account of nature’s ingenuity, and the result is a work of essential reading for anyone who has ever pondered or questioned the science underlying evolution’s greatest gifts to man.

    I was also a fraud, a liar and a cheat. Those lists of birds seen, ticked off like Don Juan’s conquests? A tissue of lies. One hundred and thirty species? More like 60. Dotterel, firecrest, smew? Give me a break.So when I revived my dormant mania early this year, I decided to right my childhood wrongs, even though they were born of good intentions. I would go birdwatching again. I would keep track of the birds I saw. I would not lie. To spice things up, and to guard against enthusiasm fatigue, I set myself a target. Six hundred and one bird species have been recorded in Britain. I would aim to see 200 of them in a year. A doddle, surely?Not so fast, man-cub.Half of the 601 are described as ‘rare’. One, the great auk, is extinct. That leaves 300. My friend Andrew is a proper and active birder. In his best year he clocked up 206. I’m neither proper nor active. What chance do I have? Slim to none. But I like a challenge.Why Do Birds Suddenly Disappear? is the story of that challenge. But it’s not just about birds. It’s about family, music, nostalgia; hearing the stories of strangers; the nature of obsession and obsession with nature. It’s about finding adventure in life when you twig it’s shorter than you thought; losing and regaining contact with the sights, sounds and smells of the natural world; the humiliation of being a professional musician who doesn’t recognise the song of a blue tit. It’s about the first time my parents heard me say ‘fuck’.It’s a book for anyone who has ever seen a small brown bird and wondered what it was, or tried to make sense of a world in which we can ask ‘What's that bird?’ and ‘What's for lunch?’ and get the same answer. It’s also a long overdue thank you letter to my parents.

    The proctored TEAS test, developed by Assessment Technologies, Inc. (ATI), measures basic essential skills in reading, mathematics, science, and English and language usage.

    This friendly, relatable book is a celebration of the art, science, and delights of bird-watching.How to Know the Birds introduces a new, holistic approach to bird-watching, by noting how behaviors, settings, and seasonal cycles connect with shape, song, color, gender, age distinctions, and other features traditionally used to identify species. With short essays on 200 observable species, expert author Ted Floyd guides us through a year of becoming a better birder, each species representing another useful lesson: from explaining scientific nomenclature to noting how plumage changes with age, from chronicling migration patterns to noting hatchling habits. Dozens of endearing pencil sketches accompany Floyd's charming prose, making this book a unique blend of narrative and field guide. A pleasure for birders of all ages, this witty book promises solid lessons for the beginner and smiles of recognition for the seasoned nature lover.

    But our burrowing roots go back to the very beginnings of animal life on earth. Without burrowing, the planet would be very different today. Many animal lineages alive now—including our own—only survived a cataclysmic meteorite strike 65 million years ago because they went underground.On a grander scale, the chemistry of the planet itself had already been transformed many millions of years earlier by the first animal burrows, which altered whole ecosystems. Every day we walk on an earth filled with an under-ground wilderness teeming with life. Most of this life stays hidden, yet these animals and their subterranean homes are ubiquitous, ranging from the deep sea to mountains, from the equator to the poles.Burrows are a refuge from predators, a safe home for raising young, or a tool to ambush prey. Burrows also protect animals against all types of natural disasters: fires, droughts, storms, meteorites, global warmings—and coolings. In a book filled with spectacularly diverse fauna, acclaimed paleontologist and ichnologist Anthony Martin reveals this fascinating, hidden world that will continue to influence and transform life on this planet.

    But every time they think they've finally closed the door, the bird makes an unexpected appearance. It happened in the 1920s, and it’s happened in almost every subsequent decade. For more than 60 years, each sighting has been met with ridicule and scorn. Respected researchers and naturalists have been branded as quacks just for having the temerity to say that the ivory-bill still exists. Yet the reports still trickle in. Is there any truth to these sightings, or are they just a case of wishful thinking, misidentification, or outright fabrication? To unravel the mystery, author Tim Gallagher heads south, deep into the eerie swamps and bayous of the vast Mississippi Delta, searching for people who claim to have seen this rarest of birds and following up—sometimes more than 30 years after the fact—on their sightings. He meets a colorful array of characters: a cigar-chomping ex-boxer who took two controversial pictures of an alleged ivory-bill in 1971; a former corporate lawyer who abandoned her career to search for ivory-bills full time; two men who grew up in the ivory-bill’s last known stronghold in a final remnant of primeval forest in Louisiana. With his buddy Bobby Harrison, a true son of the South from Alabama, Gallagher hits the swamps, wading through hip-deep, boot-sucking mud and canoeing through turgid, mud brown bayous where deadly cottonmouth water moccasins abound. In most cases, they are clearly decades too late. But when the two speak to an Arkansas backwoods kayaker who saw a mystery woodpecker the week before and has a description of the bird that is too good to be a fantasy, the hunt is on. Their Eureka moment comes a few days later as a huge woodpecker flies in front of their canoe, and they both cry out, “Ivory-bill!” This sighting—the first time since 1944 that two qualified observers positively identify an ivory-billed woodpecker in the United States—quickly leads to the largest search ever launched to find a rare bird, as researchers fan out across the bayou, hoping to document the existence of this most iconic of birds.

    Birdsong in a Time of Silence is a lyrical, uplifting reflection on these sounds and what they mean to us.From a portrait of the blackbird - most prominent and articulate of the early spring singers - to explorations of how birds sing, the science behind their choice of song and nest-sites, and the varied meanings that people have brought to and taken from birdsong, this book ultimately shows that natural history and human history cannot be separated. It is the story of a collective reawakening brought on by the strangest of springs.
