摘要

"Niche construction changes our conception of the evolutionary process ... and should be regarded, after natural selection, as a second major participant in evolution." So argue the authors of this book as early as page 2. But what exactly is niche construction? And if it's really so important, how could evolutionary biologists have neglected it for so long? The concept of niche construction is relatively simple. All living creatures, through both their metabolism and their behaviour, actively change and control the world in which they live. Organisms choose habitats and resources; they construct nests, holes, burrows, webs or pupal cases; and they modify the chemical environment in which they live. These alterations, which occur at scales ranging from the extremely local to the global, inevitably modify some of the selection pressures acting on the organisms. And it is precisely this ― the effects of an organism on its own environment ― that the authors believe to be the important component that has been neglected by the conventional theory of evolution.
