new study suggests that long-distance runners are more attractive because they have greater levels of testosterone which makes them more manly and fertile.But there are other biological and evolutionary triggers which are constantly drawing us to certain individuals, even if we don’t realise it is happening. Scientists in Geneva discovered that determining whether we are attracted to someone is one of the most complex tasks that the brain undertakes. Here are the scientific secrets of attraction:
Probably the most important is facial symmetry. Having a face which is equal on both sides is a biological advert which tells prospective partners that good genes will be found in this body.
Lopsidedness is thought to reflect how development in the womb has been derailed by general poor health, bad DNA, alcohol or tobacco use.
It is why so many people are choosing plastic surgery to straighten noses, and even-up lopsided grins. However, biologically, they are cheating their partners, as they will still pass on their wonky genes no matter what they look like from the outside.
And the importance of symmetry does not stop at facial features.
Studies have also shown that women partnered to men with symmetrical bodies have the most orgasms, and those with symmetrical breasts are more fertile than those less evenly endowed.
Even female swallows prefer males with symmetrical tail feathers as they hunt for superior genetic quality and developmental stability.
Finger lengthWhile many women might be looking for the tell-tale signs of a wedding ring, research suggests men’s hands can reveal a whole lot more.
In recent years scientists have discovered that there is an intriguing link between finger length and the levels of testosterone that a man was exposed to while still in the womb.
The longer the ring finger is in comparison with the index finger, the more testosterone was present.
That’s important because high levels of testosterone are linked to high sperm counts, increased fertility, good cardiovascular health and better genes. People with longer ring fingers are also likely to have symmetrical faces.
But before you start looking for men with extraordinarily long ring fingers, bear in mind that Oxford University discovered that they are likely to be more promiscuous. In contrast those whose fingers are a similar length are more likely to seek long-term relationships and stay faithful.
