Discuss the Biological Theory of romantic relationships.

The Biological Theory suggests that romantic relationships are influenced by our biology and genetics.

According to this theory, humans are biologically programmed to seek out romantic relationships as a means of survival and reproduction. This can be seen in the release of certain hormones, such as oxytocin and dopamine, which are associated with feelings of bonding and pleasure.

Research has also shown that certain genes may be linked to our ability to form and maintain romantic relationships. For example, a study found that a variation in the gene responsible for producing oxytocin receptors was associated with a person's ability to form strong emotional bonds with their partner.

Furthermore, the Biological Theory suggests that our evolutionary history plays a role in shaping our romantic relationships. For example, men may be more attracted to women who exhibit signs of fertility, such as a youthful appearance and a waist-to-hip ratio of 0.7, as this indicates a higher likelihood of successful reproduction.

However, it is important to note that the Biological Theory is not the only explanation for romantic relationships and does not account for the role of social and cultural factors. Additionally, it is important to recognise that individuals have agency and are not solely controlled by their biology.
