Structural adaptations are the physical features of an organism that help it to survive and succeed in its environment. Structural adaptations can affect the way the creature moves, eats, reproduces or protects itself.Continue Reading
Structural adaptations are the result of the evolutionary process, which stems from the mutation of genes over time. Some mutations are of benefit to the organism while others are not. Creatures with beneficial adaptations, such as sharper teeth for a carnivore, for example, or a longer bill in a bird, are more likely to survive longer and breed successfully. The beneficial adaptations eventually spread throughout the gene pool of the species across thousands of years.
The specific characteristics of each species are the result of structural adaptation. Some examples include:
The theory of structural adaptation comes from Darwin's observation of finches on the Galapagos Islands. The finches had all come from the mainland and were all the same physically at one time. Yet, he saw that in each area of the islands, there were subspecies of finches that had different beaks and adapted to the unique food sources of their specific environment.Learn more about Biology
Some of the characteristics of living things are the ability to reproduce, active response and adaptation to the surrounding environment, cell composition and growth and development. Life forms have to exhibit all the characteristics to be considered a life form; spontaneous generation from chemical reactions is not an example of a life form.Full Answer >
The characteristics that all living things share are cells, growth, reproduction, adaptation, homeostasis, use of energy and response to the environment. Using these characteristics, it is easy to determine if something is living, dead or non-living.Full Answer >
Organisms often respond to their environment through adaptation. Organisms that make an adjustment to environmental conditions in their own lifetime make physiological adaptation. If the adaptation takes place over several generations, the trait is an evolutionary adaptation. According to Reference.com, the ability to make adaptations is a fundamental property of life.Full Answer >
A niche is the role an organism fills within its environment. What and where an animal eats are considered part of its niche. For instance, some birds, such as woodpeckers, eat insects in trees. This limits the bug population and keeps bugs from overtaking the environment.Full Answer >
