Adaptive radiation is <span>a pattern of evolution in which several closely related, yet different, species evolve from one common ancestor in order to adapt to different environmental pressures convergent evolution.
Gradualism is a theory of evolution that states that a species evolves by consistent, small, steps.
Punctuated Equilibrium is a theory of rapid change and then goes through periods of no change.
Divergent evolution is a pattern of evolution in which very different species evolve form one common ancestor due to their adaptation to different pressures from the environment.
Analogous means to be evidently similar in some way or are related.
Coevolution is a pattern where two species evolve in relation to each other.
Convergent evolution occurs when two very different species evolve similar characteristics triggered by the environment they both live in. </span>
