When we think of wild animals, we don't immediately associate them with the cities we live in. But a closer look soon reveals that we share our urban environment with a great many untamed creatures. Heavily illustrated and full of entertaining and informative facts, City Critters examines how and why so many wild animals choose to live in places that, on first glance at least, seem contrary to their needs. How do those deer, raccoons, squirrels, skunks, coyotes, crows, gulls and geese-not to mention the alligators, eagles, otters and snakes-manage to survive in the big city? What special skills do city critters have that many of their wilderness cousins lack? Why have they developed these skills? And what are our responsibilities in ensuring that these animals can continue to share our city lives?
From the earliest times humans have shaped and changed the landscape. Historical and modern-day examples in this interesting book show how natural habitats and wilderness areas are destroyed as people need more land for farming and to build towns and cities, and how increasing urbanization of populations is adding to the problem of carbon emissions that cause climate change.
This engaging title examines how Darwin developed his controversial theory of evolution, including his research methods and the data gathered during his extensive voyages. The book also explores the controversies that developed around the publication of Darwins theory of natural selection and how the debate continues today.
This fascinating new title examines the sequence of events that led to the formation of cell theory. In 1665, scientist Robert Hooke published Micrographia, the first significant work focused on miscroscopial observation. His groundbreaking work inspired scientists and led to the creation of this fundamental biological principle that shaped modern biology.
Who are we, really? We share traits with our parents, but our genetic makeup is unique. Each one of us is a one-and-only creation. Through colorful photos, diagrams, and text, you can learn about genetics. See how the simple pea plant taught us the rules of inheritance. Find out how our genetic code is unlocking the mystery of where we came from and our connections with all living things.
All life starts with a set of instructions that can turn basic cells into hearts, tails, flower petals, or toenails. DNA is the amazing code of life that is found in every organism. Through colorful photos, diagrams, and text, you can learn how DNA is passed from cell to cell, controlling growth and change in all living things. Find out how we can use the properties of DNA to save endangered animals and even to catch criminals!
From insects to elephants, every living thing on this planet is made up of cells, the tiny building blocks of plant and animal life. Each cell is alive-and each has work to do! What do cells look like? How do millions and billions of cells work together to form one plant, one animal, or one human being? Guided by colorful photos, diagrams, and text, you can take a closer look at the amazing world of cell science-and see what's next.
