Briefly discuss Lamarckian Theory of Inheritance citing an appropriate example.

Briefly discuss the Theory of Natural Selection as given by Darwin.

The theory of Inheritance of acquired characters was proposed by Watson and Crick.

Natural selection is the only cause of evolution.

Darwin explained the inheritance of vestigial organs.

The traits acquired by the organism during his lifetime due to changes in environmental conditions are called acquired traits.

Lamarck published his principles in the book called 'The Origin of species'.
