All organisms have adaptations that aid them survive and prosper. Some adaptations are structural. Structural adaptations are physical functions of an organism like the bill on a bird or the hair on a bear. Other adaptations are behavioral. Behavioral adaptations are the things organisms carry out to survive. For instance, bird calls and also migration are behavior adaptations.

Adaptations are the result of evolution. Evolution is a change in a varieties over long periods of time.

Adaptations commonly occur bereason a gene mutates or alters by accident! Some mutations can assist an animal or plant survive better than others in the species without the mutation.

For example, imagine a bird species. One day a bird is born with a beak that is longer than the beak of other birds in the species. The longer beak helps the bird capture even more food. Since the bird can catch even more food, it is healthier than the other birds, stays much longer and breeds more. The bird passes the gene for a much longer beak on to its offspring. They likewise live much longer and also have even more offspring and the gene proceeds to be inherited generation after generation.

Eventually the much longer beak deserve to be discovered in every one of the species. This doesn"t take place overnight. It takes countless years for a mutation to be discovered in a whole species.

Gradually, pets that are much better adjusted to their setting make it through and breed. Animals that are not well adjusted to an environment may not endure.

The features that assist a types make it through in an environment are passed on to future generations. Those features that do not assist the species make it through slowly disappear.
