Mutations are permanent changes to genetic material that can be passed on to offspring. These changes happen randomly and can occur in any type of gene. While some mutations are not harmful (hazel eyes, for example), many mutations have harmful effects on health.
Analagous structures. For example, both penguins and dolphins have torpedo shaped heads that help them adapt to their enviroments. They were both in different environments, but they developed similar adaptations to increase their ability to survive in their environments.
