Zoo.223 Evolutionary Biology 3+1

LEARNING OBJECTIVES:

The primary objective of this course is -
 To provide comprehensive overview of Concept of Evolution.
 To explore salient features of various theories of evolution comprising of Lamarckism,
Darwinism and Neo-Darwinism
 To develop comprehensive knowledge regarding various Sources of Variations and their
role in evolution.

LEARNING OUTCOMES:

This course will enable the students to:
 After successful accomplishment of the course, the students will be able to learn most of
the essential aspects of Evolutionary Biology in detail which will help them in acquiring
better understanding regarding the subject.
 Understand the Phylogenetic Trees and highlight their construction along with
interpretation.
 Learner will have descriptive knowledge regarding Origin and Evolution of Man.
