Answers
Progressive evolution is a process where simple form of organism develop towards complex form. Example: evolution of unicellular organism into multicellular organism.
Retrogressive evolution is a process where complex form of organism develop towards simpler form. For example: Monocot plants belong to a more advanced group of plants with herbaceous and simple structure.
Progressive and retrogressive are based on evolution characteristics:
Progressive evolution:
The Progressive evolution is when an organism increases the complexity and develops a highly complex nature with time duration. This evolution makes the organism to become more independent.
Retrogressive evolution:
The retrogressive evolution is opposite and different. The organism in the case of retrogressive evolution forms the more advanced characteristic in favor of a more primitive one. The organism is getting better through evolution.
