First – the bad news! Imbalance between males and females – in all animal species – means sexual conflict is unavoidable. Take humans, for example. Men can’t help it. They want to maximise their mating efforts. And women – however powerfully-dressed – want to maximise their rearing efforts.
So next time you’re out hoping to date and mate, you can take heart. You’re not alone. And, so what if you’re picky. The benefits of Choosiness, say the Liverpool Researchers, mean that you’re going to سرمایه گذاری مدیریت ثروت لیورپول seek out the best genes available. You may also be lucky enough to find good paternal care for your off-spring all wrapped up in the same genetic parcel. But – simply looking at someone across the dance floor isn’t going to give you any info about that. And what you see may not be what you get – in all senses.
Peacocks – to take a parallel from the animal kingdom – spend a lot of time falling over their own tails. But, come the mating season, these tails are precisely what the peahens are all comparing and contrasting. Rightly or wrongly, the peahens believe, the more magnificent the tail, the greater the chances of their own offspring surviving.
Humans, of course, are not quite so easily impressed. Or are they? Evidence shows that bilateral symmetry – all things being equal – is believed to indicate good genes. Men with bilateral symmetry make better athletes – at least, better dancers – and have more masculine faces. And attract beautiful women.
So what can the not-so beautiful people do? Some good news – women who think themselves less attractive favour more feminine features in a man’s face. And these women are more interested in compatibility of genes than visual stimuli. At heart, they are looking for a bag of genes which will add to their own and create an off-spring whose mixed gene pool will be more able to fight infection.
The downside here? A good sense of smell is required to make the best choice. And the best choice has to be scented across a confusing array of perfumes and odours. This works both ways. Most women in a dating mood will be on the Pill. Once they’re married – and want children – they may come off the Pill. And their mate – foxed by subtle changes in the aroma of pheromone- may think he no longer loves his wife. This confused perception has even been known to result in separation and divorce – so the consequences of this form of selection are not to be regarded lightly.
Going back to first principles, in the biological market place – where mate value offers bargaining power – what can the lesser mortals do? Wearing red or black helps, say the Liverpool Researchers. But other issues are at work. You may go for people who look like your opposite sex parent. This is called imprinting. Equally, you be lucky enough to find people who look like you but are sufficiently genetically dissimilar to mean that any children you may have can fight the common cold with a will!
