If you forget all the red roses, fancy cars and other “romantic” gestures we frequently see involved in courtship today and look back at what drew our ancestors together, the picture looks a whole lot different.
Not unlike animals today, people were drawn together by choosing what qualities would compliment their own when it came to producing offspring. This is still done today, though usually on a subconscious level. For instance, men are drawn to women with curves which makes them ideal candidates for bearing a healthy child. Women on the other hand are drawn to men with symmetrical faces for much the same reason, they appear to have genes that would benefit their offspring. According to a new study, there may be another less obvious factor for attractiveness – a healthy immune system.
