Question

Match each species with its mode of evolution. 1. bees and flowers 2.cichlid fishes 3.flying squirrel and flying phalanger

Answer 1

1. bees and flowers  - coevolution 
2. cichlid fishes- divergent evolution
3.flying squirrel and flying phalanger - Pairs convergent evolution

Answer 2

I. Bees and flowers: This is a very common example of mutualism. In this mutual relationship bees receive food i.e nectar and pollen where as the plants get benefited by dispersing their pollen. Flowers and bees have coevolved i.e. evolved together for millions of years.

2. Cichlid and fishes : Adaptive radiation/adaptive evolution

3. Flying squirrel and flying phalanger: it is an example of convergent evolution as they don't have recent common ancestor but still share many common characteristics.
