According to evolutionary theory, how does a new species develop?

Organisms (belonging to the same species) may adapt in different ways to better exploit different environments or resources-- survival of the fittest. They also may evolve varied characteristics for attracting mates for reproduction. This means that different groups evolve differently. Over time, these groups or populations may become so different that they can no longer breed together -- and separate species are formed.
