Formation of more complex and specialized organisms from the simple and less elaborated forms is called
- Retrogressive evolution
- Progressive evolution
- Microevolution
- Macroevolution
The correct answer is: Progressive evolution
Evolution is commonly defined as any process of growth or development from one stage to another. Progressive means favouring or advocating progress, change, improvement and movement towards better conditions. Biological evolution refers more specifically to the changes in the gene pool of a population from generation to generation by the processes such as mutation, natural selection, and genetic drift
