Heredity and Evolution

Every person shows some resemblance to his/her parents. This happens because of heredity. The inheritance of characters through generations is called heredity. Heredity results in some variations through subsequent generations. When these variations accumulate over thousands of generations, they give rise to a new species. This is a long drawn process and is called evolution. Scientists have proved that life originated on the earth in the form of unicellular organisms and all the complex organisms; which we see today; have evolved from those unicellular organisms. Mendel was the pioneer in study of heredity and had given new insights into mechanisms of heredity. Darwin and Lamarck proposed various theories of evolution which have helped us in understanding evolution in a better way.
