Life on earth has suffered occasional mass extinctions at least since 542 million years ago. Although they are disasters at the time, mass extinctions have sometimes accelerated the evolution of life on earth. When dominance of particular ecological niches passes from one group of organisms to another, it is rarely because the new dominant group is "superior" to the old and usually because an extinction event eliminates the old dominant group and makes ...
Most plants that people tend to think of are vascular (they contain internal tubes for transporting food and water within them) such as most house plants, flowering plants, etc. Bryophytes have poorly developed tubes--they are non-vascular plants. And, instead of reproducing with seeds, Bryophytes reproduce using spores.Because of the way Bryophytes transport food and water, and because they require water for reproduction, Bryophytes are small plants, and are ...

The present title “Prehistoric Life†deals with geological periods, plaecontological localities, plants, invertebrates, fishes, amphibians, reptiles, birds, mammals, the rise of man and morphological topics. The Prehistoric Life describes the earliest forms of plants and animals, most of which have become extinct, and traces the evolutionary development of the creatures whose descendants have survived until the present day. The material presented in the ...
The Present title “Vanishing and Endangered Species†is written for both non science and science majors as an introduction to historical life science. Although it is likely that many students will have already taken an introductory life science, physical geology or earth science course, this background is not assumed. Accordingly, the book stands on its own and presents a comprehensive picture not only of earth’s history but also of the geological forces ...

The present title introduce the sciences of immunology to provide a comprehensive over view of basic immunology that could serve either as a text book for introductory courses or as a concise, state-of-the-art review for practicing physicians and scientists from immunology and other related fields. It covers molecular and cell biology of defence mechanisms in health and diseases. Efforts have also been made to make the presentation lucid and accessible for ...
The present title "Biology of Reptiles" has been designed to approach the morphology, anatomy, physiology and development of reptiles in a coherent way since it is most natural for a student in studying the architectural elements of an animal body in the quest to know how they function. This text intends, therefore, to enable the student, through his own natural appetency, to correlate form and function so that he possesses for subsequent work in either ...

In art, mythology, and folklore, birds have been used for centuries to symbolize wisdom and truth, strength and power, birth and death. However, nothing about birds has tantalized humans more than the gift of flight. There are birds that "fly" through water, others that can attain incredible speeds while swooping on prey, and some, such as the hummingbirds, that are extraordinarily agile and can even fly backwards. But what unites and defines these ...
