Explanation
Homologous organs are functionally different but structurally alike e.g. Fore limbs of man, bat, horse, whale etc. are examples of divergent evolution. Analogous organs are functionally alike but structurally different e.g. wings of bat, birds and insects etc. are examples of convergent evolution.

About Evolution
Evolution describes heritable change in populations over generations through variation, natural selection and adaptation. Lamarckism explains inheritance of acquired characteristics, while Darwinism explains selection of favourable inherited variations; these historical explanations must not be confused with the modern genetic account of evolutionary change.
