Astrobiology is an exciting new subject, and one, arguably, more interdisciplinary than any other. Astrobiologists seek to understand the origin and evolution of life on Earth in order to illuminate and guide the search for life on other planets. In this Very Short Introduction, David C. Catling introduces the subject through our understanding of the factors that allowed life to arise and persist on our own planet, and for the signs we are looking for in the search for extraterrestrial life. 

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.

Oliver Sacks is well known as an explorer of the human mind - a neurologist with a gift for complex, insightful portrayals of people and their conditions. However, he is also a card-carrying member of the American Fern Society, and since childhood has been fascinated by these primitive plants and their ability to survive and adapt in many climates. Oaxaca Journal is Sacks' spellbinding account of his trip with a group of fellow fern enthusiasts to the beautiful, history-steeped province of Oaxaca, Mexico.

Call it "Zen and the Art of Farming" or a "Little Green Book", Masanobu Fukuoka's manifesto about farming, eating, and the limits of human knowledge presents a radical challenge to the global systems we rely on for our food. At the same time, it is a spiritual memoir of a man whose innovative system of cultivating the earth reflects a deep faith in the wholeness and balance of the natural world. As Wendell Berry writes in his preface, the book "is valuable to us because it is at once practical and philosophical."

Our sense of smell - or olfaction as it is technically known - is our most enigmatic sense. It can conjure up memories, taking us back to very specific places and emotions, whilst powerful smells can induce strong feelings of hunger or nausea. In the animal kingdom smell can be used to find food, a mate, or a home; to sense danger; and to send and receive complex messages with other members of a species. Yet despite its fundamental importance in our mental life and in the existence of all animals, our scientific understanding of how smell works is limited.

Today there is no place on Earth that does not harbor invasive exotic species. Invasive plants and animals can be found on every continent, including Antarctica, and within all waterbodies, including all oceans. This Very Short Introduction provides a clear definition of an invasive species, and considers the myriad ways they are moved around the globe, and the ecological, social, and economic impacts they often impose.

Cut through the medical myths and get a solidly scientific guide to keeping yourself and your loved ones as protected as possible from pathogens, including a no-nonsense guide to vaccinations, tips on keeping a healthier home environment, and valuable advice for world travelers.

August 2021. The Taliban invaded Kabul. The British Government was Missing in Action. The evacuation was disastrous, shambolic and deadly. Pen Farthing refused to abandon his charity’s staff or rescue animals. Operation Ark was born. He was branded a villain who valued “pets over people”, blamed for deserting Afghans, accused of risking British soldiers—nothing could be further from the truth.

The most joyful emanation produced by a colony of bees is known as the “song of increase”—declaring that the hive is flourishing and the bees are happy in its abundance. Song of Increase takes us inside the world of the honeybee to glean the wisdom of these fascinating creatures with whom...

Each year across the United States, there are mysterious and unexplainable firsthand encounters by average people. These encounters beg the question, do monsters exist? From east to west across the US, professionals are actively researching these encounters to prove once and for all that these creatures do exist. American Cryptids takes you on a journey across the country, visiting each state along the way.

Plants play a critical role in how we experience our environment. They create calming green spaces, provide oxygen for us to breathe, and nourish our senses. In The Nature of Plants, ecologist and nursery owner Craig Huegel demystifies the complex lives of plants and provides listeners with an extensive tour into their workings.

Biodiversity, the diversity of life, is not only fascinating and beautiful, it is the engine of all the world's natural cycles, and the source of many of the resources on which humanity depends. Concern about biodiversity conservation is, therefore, not merely the preoccupation of a few enthusiastic naturalists—it is the lifeline business of everybody.

Physiology is the science of life, and sets out to understand how living things work and what makes them distinct from the non-living. It considers how our bodies are supplied with energy, how they maintain their internal parameters, the ways in which we gather and process information, the ways we take action, and the creation of new generations.

Systems biology came about as growing numbers of engineers and scientists from other fields created algorithms which supported the analysis of biological data in incredible quantities. Whereas biologists of the past had been forced to study one item or aspect at a time, due to technical and biological limitations, it suddenly became possible to study biological phenomena within their natural contexts. 

Here is the extraordinary story of the unfolding of life on Earth, told by Michael J. Benton, a world-renowned authority on biodiversity. Ranging over four billion years, Benton weaves together the latest findings on fossils, earth history, evolutionary biology, and many other fields to highlight the great leaps that enabled life to evolve from microbe to human - big breakthroughs that made whole new ways of life possible - including cell division and multicellularity, hard skeletons, the move to land, the origin of forests, the move to the air. 

Do animals have moral rights? If so, what does this mean? What sorts of mental lives do animals have, and how should we understand welfare? By presenting models for understanding animals' moral status and rights, and examining their mental lives and welfare, David DeGrazia explores the implications for how we should treat animals in connection with our diet, zoos, and research. Animal Rights distinguishes itself by combining intellectual rigor with accessibility, offering a distinct moral voice with a non-polemical tone.

This Very Short Introduction uncovers the history of our understanding of sexual selection, from Darwin's key insights to the modern day. Considering the investment animals place on reproduction, variation in mating systems, sexual conflict, and the origin of sexual dimorphism, authors Marlene Zuk and Leigh Simmons discuss questions such as whether females can really choose between males on aesthetic grounds and how sexual conflict is resolved in different species. 

In this exploration of the concept of the gene, Jonathan Slack looks at the discovery, nature, and role of genes in both evolution and development. Explaining the nature of genetic variation in the human population, how hereditary factors were identified as molecules of DNA, and how certain specific mutations can lead to disease, Slack highlights how DNA variants are used to trace human ancestry and migration, and can also be used by forensic scientists to identify individuals in crime.

To date, more than a million insect species have been described, with probably at least another 5-8 million species waiting in the wings for a name. Insects are a fascinatingly diverse and beautiful spectrum of animals. They range in size from the tiny parasitic wasp, measuring a mere 139µm, to the aptly named Titan beetle, which can reach lengths of up to 17cm. They can be found on all continents of the world, from the Sahara Desert to the frozen wastes of Antarctica. While no insects live beneath the waves, the intrepid sea skaters skim the surface of some of the world's oceans.
