It is important to remember that genes are always being combined and re-combined to develop new combinations of the gene. These heterogeneous genes become tangled with the biological information that provides the basis for the diversity of human beings. They have a very big responsibility of passing their own genes and their culture onto their offspring and creating a new culture for the next generation. The power to make culture and pass it on to the next generation is based on the biological strength of people. Each couple makes different combinations of genes through their love, and that combination can only be made for those two particular people.
Love is a feeling that only humans can experience.
The emotional beauty and preciousness of life, burning in one's heart, has been depicted in many ways through literature, music and art. Love gives each party involved, the energy, to mutually overcome difficult challenges that may lead to greater love. The emotions associated with love may be unique to the human race where sophisticated emotional processes are involved in selecting a partner. This process of generating new genes and combining genes seems to be a necessity for fostering culture and bringing about fresh changes to that culture. Phenotypes, such as appearance, abilities, personalities, and other morphological and physiological characteristics, are originally the guideline for biological classification.
