All sorts of evolutionary theory explains why and how animals 'choose' thier partners. Selfish genery, sperm competition, sexual selection and survival... all have important points that illustrate how some unconscious choices are made. But we are Human - Homo sapiens - and supposed to be above all that sort of thing because we have a highly evolved brain and communication skills that allow us to go one better than the animals. Many do, of course, invoke moral and ethical reasoning on their own and other's sexual behaviours BUT, and it's a big BUT, initially many respond to those very same evoltionary cues that many animals (including the 'higher primates') respond to.

Women choose all sorts of things about men subconsciously. A big thing in biology is symmetry and the closer a woman is to ovulation the greater her ability, on average, to choose a man who has greater biological symmetry than his cohorts. They can also do this by smell too. Totally unconciously they will find certain men more attractive at various times in their menstrual cycle than at others. When biological measurements are taken on those men they tend to have greater symmetry.

That said, in modern terms, the size of man's bank account may well influence some. You get some men who are not biological prime specimens but that does not mean they could not be a good Father or partner. Having a father for your children and a man to give you those children could actually mean two partners and this happens in a lot of so called monogamous species.

I use the words 'on average' a great deal because it is all one can say in truth. There will always be exceptions to the rule and these can be quite normal too in a need to survive way. Not all men do choose large breasts and hips on a young woman, but on average they do for very strong biological reasons.

It's all very complex and no short commentary here could ever do justice to the subject. A great book to read, if you can get hold of it now, is "The Red Queen Hypothesis" by Matt Ridley. It explains many of the reasons why various things happen in the animal kingdom to do with sexual selection.

Sit at a bar on a Friday and Saturday night and watch the games people play after reading that book!

All that said, many people find their ideal partner way outside of what biology says they should and they remain happy, raise children and make wonder parents and partners. For those who get it right the rules still apply, inasmuch as it can be explained, and nice guys can finish first.

It's not all the woman's doing and we get blamed for a great deal but, very basically, women have something men want and that will always make for currency in the biological world. Women can still get turned on by what a man has between his ears too, and vice versa, so for guys who can write songs that touch a nerve...

How many here go for guys with deeper voices? That, too, appears to be on the list of how a woman may choose a partner. And balding men are said to have higher testosterone levels (which is why some have more hair on their body than on their heads). But only some.

It's great fun when it all goes right :-)

Cannot wait for the first song to be written on the subjects. Truth is that they already have under different auspices lol
