Morphological adaptations are physical changes that occur over many generations of living things such as animals and plant life. The observations made by Charles Darwin, which included a finch whose beak had adapted to eat a certain type of diet on the Galapagos Islands is an example of a morphological adaptation.
Adaptations of different species fall under the category of physical and behavioral. Both types of adaptations are essential to the survival of a species.
These adaptations spurred Darwin's theory of natural selection. During millions of years, it is thought that one species of finch adapted to the unique island environment and evolved into 13 separate species. Each type of finch has unique characteristics that allow it to eat certain insects, flowers or seeds.
