The book traces the ways in which terrestrial animals have evolved from aquatic ancestors and discusses the means by which they are adapted to life on land. The most important physiological adaptations are those involving salt and water balance, the excretion of nitrogen, reproductive mechanisms and the sense organ and these are given priority. Evidence from fossil history is combined with that from the ecology and physiology of present-day species to assess the probable routes along which various evolutionary lines had moved on to land. Individual chapters are concerned with specific animal groups and emphasis is placed on comparisons of physiological mechanisms between closely related animals before attempting wider generalisations. The book closes with a brief account of the recolonisation of the sea and fresh waters by terrestrial animals.
The theme of this book is the invasion of land by animal lines which originated in aquatic environments. It brings together physiological and ecological evidence to show both the likely routes taken out of the sea by the aquatic ancestors of terrestrial animals and the changes in structure and function associated with these routes. The author takes an ecophysiological approach, and by using representative examples, provides a novel background against which both the terrestrial adaptations of individual species and the make up and function of terrestrial ecosystems can be considered. Dr Little is the author of the highly acclaimed book The Colonisation of Land, which discusses the phylogeny and physiology of terrestrial and semi-terrestrial animals. The Terrestrial Invasion takes a fresh approach and provides an excellent introduction to the origins of land animals suitable for ecologists, physiologists and evolutionary biologists.
