Life

Scientists have been cataloguing life for over 200 years, yet there are still many thousands of undiscovered species. From a microscopic cell to the most complex mammal, this intriguing book helps us to understand living things in the forms we know of, and to speculate about the ones we do not. Geologists have found the fossilised remains of organisms that are over 3 billion years old, almost as old as the Earth itself. These early life forms were little more than chance chemical reactions. Since then millions of different species have developed, each with its own DNA pattern and means of reproduction. We human beings have developed enough to study and genetically engineer life, and look for other life beyond our galaxy. Featuring historic scientific apparatus and ground-breaking experiments and discoveries, Life is a unique and exciting introduction to this fascinatingly endless subject.
