Question
Describe Lamarck's theory of evolution.
✓
Answer
Lamarck's Theory:
Lamarck's theory is known as theory of Inheritance of acquired characters.
According to this theory, organisms undergo certain changes to adapt themselves to the environment.
These characters acquired by an organism during its life time, are passed on to the progeny, e.g. the long neck of giraffe was explained by Lamarck, as an outcome of these animals having to stretch their necks constantly to eat the leaves on the upper branches of the trees.
