Love is a product of genetics and evolution

The laws of love are predetermined by genetics and evolution. We are programmed to love those that come from the same bloodline as us. Therefore, we instinctually love our parents, our siblings and our children.^[1] When we find a potential mate, we naturally are predisposed to fall in love with those that would provide the best offspring. Universal standards of attractiveness can all be traced back to evolutionary terms. Men with big muscles, broad shoulders, and narrow hips might be considered attractive because they can protect the female and the offspring. A youthful looking woman might be considered more attractive because women are more fertile in their 20s than in their 50s, for example, and it subliminally informs males that she may be able to give them offspring.^[2] Once we choose a mate and a child is conceived, often a monogamous relationship forms. This is also a product of our desire to pass on our genetics. In most primates, a mother will not mate until her infant has weaned. In the animal kingdom, a male who wishes to mate with the mother will kill the infant. However, almost a third of primates form monogamous relationships with the other parent of their child. They do this to prevent other males from killing their infant. Researchers at University College London believe that this is how monogamy developed over 20 million years.^[3] Love is evolution. It is the manifestation of our species determination to survive and flourish. There is nothing more to it than that.

[P1] Monogamy, choosing our partner, and universal standards of attractiveness are predetermined by genetics and evolution. [P2] Love is the way our species reproduces and evolves. [P3] Therefore, love is just science and reproduction.
