Answer:
1. a pattern of evolution in which very different species evolve from one common ancestor divergent evolution
2. a pattern of evolution in which two species evolve in relation to each other coevolution
3. a theory of evolution that states that a species evolves by consistent, small, steps gradualism
4. a theory of evolution that states that a species evolves in spurts of rapid change and then no change punctuated equilibrium
5. a pattern of evolution in which similar characteristics evolve between two unrelated species convergent evolution
6. a pattern of evolution in which slightly different species evolve from one common ancestor adaptive radiation
Step-by-step explanation:
Adaptive radiation and divergent evolution are two similar mechanisms of evolution of species from a common ancestor. The main difference is that in divergent evolution new species form from a pre-existing species, while in adaptive radiation diversification of a species into various new forms occurs.
Gradualism and punctuated equilibrium are two ways of the evolution of a species with the difference that gradualism occurs slowly.
Convergent evolution leads to the development of structures that are similar but have developed independently and those structures are then called analogous structures.
