👇 Watch the Full Lecture to Master These Topics:
Lamarckism: Theory of Inheritance of Acquired Characters, Postulates (Use & Disuse, Internal Vital Force), and Classic Examples.
Darwinism: Theory of Natural Selection, Darwin's Voyage & Observations, Key Postulates (Struggle for Existence, Survival of the Fittest), and Real-world Examples (Industrial Melanism, Antibiotic Resistance).
Neo-Darwinism (Modern Synthesis): Integration of Genetics with Natural Selection, Evolutionary Forces (Mutation, Gene Flow, Genetic Drift), and Population as the Unit of Evolution.
Comparative Analysis: Clear differences between all three theories, exam-oriented concepts, and practice MCQs.
