Adaptation: The Driving Force or a Result of Evolution?
Lobsters and dolphins are adapted to aquatic life whereas the green woodpecker and the fly are adapted to aerial life. The way in which these organisms are constructed allows them to execute certain functions within certain environments. This is a first, simple definition of adaptation which describes:The evolutionary process of adjustment of an organism to its environment. This historical aspect will be discussed in subsequent chapters.The result of this process — the state of adaptation — or the form of an organism at a certain point in its history. This functional-structural aspect will be dealt with here.
