Course Name : Evolutionary Biology

Code(Credit) : CUTM1510(3-2-1)

Course Objectives

  • • To provide comprehensive overview of Concept of Evolution.• To explain Origin of Life especially Prokaryotes as well as Eukaryotes in detail.
    • To provide adequate information about Geological Time Scale
    • To give detailed outline of Extinctions and its types.
    • To impart descriptive knowledge regarding Origin and Evolution of Man.

Learning Outcomes

  • • Students understand and explain the main forces of evolution (natural selection, sexual selection, genetic drift). and the interplay among them, both over ecological and evotionary time.
    • Students understand the history of life; the evolution of humans
