Mutations are when the structure of a gene is changed or "mutated". In other words, your DNA sequence is altered. Most of the mutations that we think matter to evolution are "naturally-occurring. For example, when a cell divides, it makes a copy of its DNA, however, sometimes the copy is not perfect. That small difference from the original DNA sequence is a mutation. Below are some examples of mutations:
Adaptations:
An adaptation is a physical or behavioral trait that has developed to allow an organism to survive in its environment or habitat. Adaptations are the result of evolution and may occur when a gene mutates, or alters. That mutation helps the organism survive and reproduce, and it passes on that trait to its offspring. One example of an adaptation would be a crab's shell. This shell protects it from predators and from crashing waves.
