Adaptations are the an outcome of evolution. Evolution is a readjust in a varieties over lengthy periods that time.
Adaptations typically occur since a gene mutates or transforms by accident! some mutations can assist an animal or tree survive far better than rather in the types 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 much longer beak helps the bird catch much more food. Due to the fact that the bird deserve to catch an ext food, the is healthier than the various other birds, lives longer and also breeds more. The bird passes the gene for a longer beak on to its offspring. They likewise live longer and have more offspring and also the gene continues to be inherited generation after ~ generation.
Eventually the much longer beak can be discovered in every one of the species. This doesn"t take place overnight. The takes countless years for a mutation to be discovered in an entire species.
Over time, animals that are far better adapted to their setting survive and also breed. Animals that are not well adapted to an atmosphere may no survive.
The qualities that help a species survive in an atmosphere are pass on come future generations. Those characteristics that don"t aid the types survive progressively disappear.
