Synopses & Reviews
This series explains how the diversity of life on Earth has developed over millions of years, through a combination of gradual change and dramatic events. It reinforces student knowledge about the survivability of plants and animals in environments and provides a substantial background on the earth sciences, such as geological processes. It looks in depth at biological adaptation over time. Topics covered include: genetic variation and mutation; the role of environmental change both gradual and catastrophic; competition for resources; the distribution of organisms; the extinction of species; geological and fossil evidence; comparative anatomy; theories of evolution; and scientists at work today.
How has Earth and life on it changed? What is a "living fossil"? Why did the dinosaurs become extinct? 'Extinctions of Living Things' looks into the evolution of living things and the disappearances of species, the effect humans have on extinctions, and how modern scientists are striving to protect threatened species. Look into catastrophic ecological changes that blitzed species, study fossils of giant sea creatures, judge if we are to blame for the disappearance of the dodo, and assess if dinosaurs are still alive today. Life on Earth is constantly changing. It has been doing so for as long as we know and far before humans were here. Through the use of detailed case studies and scientific theories, the books in the 'Timeline: Life on Earth' series discuss how changes are studied, what the evidence reveals, and how such changes have had - and continue to have - an impact on Earth.
