Most mutations are neutral, they are neither beneficial nor deleterious, so your “not suited” is mostly incorrect. A neutral mutation is equally suited, but different from the standard DNA. Blue eyes as opposed to brown eyes is an example. Both work, but blue eyes are a mutation.Then we should see examples of evolution bringing about something that is not suited to their environment.
Can you point these out?
A very mildly deleterious mutation might hang around as a result of chance for a time, or simple recur in new individuals each generation. Achondroplasia is such an example. It can be inherited and it can appear in families with no previous history of Achondroplasia. It is mildly deleterious in humans, though it is a definite advantage in Dachshunds, which have the same mutation.
