Conner Patterns of Evolution Notes

Multiple Choice

Quite often we see organisms that have similar characteristics, not because they have arisen from a common ancestor, but because they have adapted to similar environments. Which type of evolution is this?

• Divergent evolution

• Convergent evolution

• Punctuated equilibrium

• Coevolution

Multiple Choice
