A woman's highly attuned smell radar help her select a mate

Women may be better at sniffing out biologically relevant information from underarm sweat, a US study suggests.

Dr Leslie Knapp, an expert in biological anthropology at the University of Cambridge, said there were good evolutionary reasons why a woman's ability to detect body odours should be more acute, as it could literally be an effective way to sniff out a suitable mate

She said: "Women perhaps need to be more discriminating when they choose who to mate with to produce offspring, as they invest more than males in the reproductive process.

Dr Knapp said there was evidence that odour gave a hint about genetic make-up. She highlighted HLA genes involved in the immune response.

She said in evolutionary terms it was desirable for a women to mate with a man whose genes were different from hers, as this was likely to produce more robust offspring.

The power of jealousy depends on how tall you are?

Short people should pray for a return to the Seventies fashion of stack heels, for the power of jealousy depends on how tall you are, the British weekly New Scientist says.

Researchers at the University of Groningen in the Netherlands and University of Valencia in Spain asked 549 Dutch and Spanish men and women to rate how jealous they felt, and to list the qualities in a romantic competitor that were most likely to make them ill at ease.

Men generally felt most nervous about attractive, rich and strong rivals

But these feelings were increasingly relaxed the taller they were themselves. The more vertically challenged the man, the greater his feelings of jealousy.

For women, what counted most in jealousy was the rival's looks and charm, but these feelings were less intense if the woman herself was of average height.

This makes sense in evolutionary terms, says New Scientist, in next Saturday's issue

Taller men are most successful with women, and women of medium height enjoy the best health, fertility and popularity with men.

On the other hand, a woman of average height could in certain circumstancesfall afoul of the green-eyed monster if their rival were taller.

"Taller women are more dominant and have greater fighting abilities than shorter women," says the study, which appears in the journal Evolution and Human Behavior.
