1. Convergent evolution - flying squirrel and flying phalanger. Convergent evolution is the process at which non monophyletic organisms, evolve similar traits. These traits are a result of adapting to similar environments but these organism still evolve them in different, independant ways.
2.Coevolution - bees and flowers. Coevolution is the process that takes place among organisms that take part in a mutual interaction during which both the organisms benefit one from another. For example: many flowers with short nectar tubes can die out, as well as well as the moths with short tongues until they meet each other and make pollination.
3. Divergent evolution - cichlid fishes. This type of evolution can be characterized as the accumulation of differences between groups that can form new species in a result of diffusion of the same ones from different environments. This process tends to block the gene flow among the distinct populations which also allows fixation of traits through genetic drift.
