   "Slutty" behaviour is good for the species. That's the conclusion of a new wave of research on the evolutionary drives behind sexuality and parenting.
   Women everywhere have been selflessly engaging in trysts outside of matrimony for a good long time and for excellent reasons. Anthropologists say female promiscuity binds communities closer together and improves the gene pool.
   More than twenty tribal societies accept the principle that a child could, and ideally ought to, have more than one father, according to Pennsylvania anthropologist Stephen Beckerman. 'It begins to crop up in a lot of places,' says Beckerman, who has reviewed dozens of reports on tribes from South America, New Guinea, Polynesia and India as co-editor of the newly released book, Cultures of Multiple Fathers.
   Less than fifty years ago, Canela women, who live in Amazonian Brazil, enjoyed the delights of as many as forty men one after another in festive rituals. When it was time to have a child, they'd select their favourite dozen or so lovers to help their husband with the all-important task. Even today, when the dalliances of married Bar ladies in Colombia and Venezuela result in a child, they proudly announce the long list of probable fathers. The much-touted evolutionary bargain of female fidelity for food -- trotted out by evolutionary psychologists with maddening regularity -- just doesn't hold up.
   'This model of the death-do-us-part, missionary-position couple is just a tiny part of human history,' says anthropologist Kristen Hawkes, who has spent years studying the Ach, a Paraguayan people, and the North Tanzanian tribe Hadza. 'The patterns of human sexuality are so much more variable.'
   American college students still learn that human society is based on the age-old economic contract between the sexes: Men hunt and women raise children.
   Fathers provide meat for the family; in exchange, moms offer fidelity and the guarantee of paternity. Although men -- who produce millions of sperm -- are inveterate philanderers, gals, stuck with relatively few eggs that require a significant investment, tend to be choosy and coy.
   'This evidence is a real thumb in the eye for that view,' says Beckerman. Anthropologists claim, good judgment aside, evolution has nudged women a bit toward promiscuity and sexual adventure. In all well-studied primates, females exhibit a polyandrous tendency when given the opportunity to stray. Some who cheat appear to be more fertile, and the offspring of most are more likely to survive. Fooling around appears to have helped our ancestral mothers equip their little ones for success -- the sexual equivalent of reading to them every night or enrolling in the after-school chess club.
   Hawkes says females likely hook up with multiple males for safety -- a mother's strong emotional bonds with more than one fellow provide an extra-protective hand in times of danger. An economic incentive promotes female infidelity in Bar society. All of the Bar children who had more than one father were more likely to survive into adulthood, fortified by small gifts of fish and game in times of scarcity.
   Even evolutionary psychologists, stout defenders of the meat-for-fidelity model, are beginning to acknowledge the benefits of women's "slutty" behaviour. University of Texas psychologist David Buss gives most credit to "mate insurance," a back-up replacement in case the male partner doesn't survive. Social approval of infidelity does not, however, imply a corresponding devaluation of marriage.
   'They're very, very faithful,' says Beckerman's co-author Paul Valentine about the Curripaco, who live on the border between Colombia and Venezuela. The tribe believes that conception is a process that requires a
lot of work, and the men are quick to take credit for their joint labours. 'They say, "Hey, this is really hard work having a baby,"' Valentine says. 'And they really put on a smug look.'
   Physiological data supports the theory that women have been sleeping around for centuries. For starters, men have evolved to compete in their partner's reproductive tract. Human males have large testicles that
manufacture plenty of semen, especially when they reunite with their wives after separation. Their sperm includes coil-tailed versions that block instead of carry the ball.
   Females co-operate when they want to -- more often with their lovers than with their mates, according to one study. Women retain slightly more sperm after orgasm, and in the throes of excitement may even draw the virgin swimmers up through the cervix and into the uterus, according to British sexologist R. Robin Baker.
   Still, David Buss places most of the blame for all this wanderlust on the guys. Bottom line, sperm are cheap and eggs are expensive, he says. He cites his own 1993 studies of college undergraduates. Women said they'd like maybe up to five partners in a lifetime. Men in various surveys ranged from 18 up to 1,000.
   Sure, both sexes have one-night stands. Both also can mate for life. But men tend toward variety and women will most often stay true to the stable, dependable provider, Buss claims.
   Anthropologists are not so sure. Some say today's emphasis on female monogamy may have more to do with socioeconomic trends than evolutionary instincts. Extramarital trysts were a way of life for the Canela -- until the encroachment of outsiders.
   'Multiple lovers, that's just part of the life. It's recreation, just like races and running. It's all done in the spirit of joy and fun,' says William Crocker of the Smithsonian Institution, who has studied the Brazilian tribe since 1957. When a woman got pregnant with her husband, she would go out to find as many as five more "fathers" for her fetus. Because every bit of semen was believed to contribute to the baby, a dedicated mom looked for a variety of desirable traits in her lovers: sexual skills, good looks, oratory talents, top-notch singing abilities -- and naturally, a good provider.
   Crocker says the Canela's sexual customs began to disappear after the arrival of traders, who brought in material goods such as machetes, axes, pots and pans, introducing the idea of exclusive ownership. The
missionaries came next. The evangelists, who arrived in the early 1970s, translated the Bible into Canelan and did their part to discourage the tribe's sexual intimacy.
   Beckerman says, 'I suppose it doesn't mean there's any less fooling around, it's just that the fathers don't take responsibility for it and the mothers don't admit it.'
   Modern relationships are not all that different. High infidelity, remarriage and divorce rates may have less to do with modernity than with our collective sexual past.
   'It makes the variation we're seeing in modern society so much more understandable,' Hawkes says. If the anthropologists are right, monogamy may well be counter-evolutionary or an adaptation to modern life. Or
perhaps the nuclear family has always been more of an ideal than a reality.

My university is a progressive, socially tolerant, arts-based institution with a reputation for, shall we say, straddling the boundaries of acceptability - a recent exhibition of student's work included a young man who was wearing only a pair of stockings, smeared in human faeces, pleasuring himself and barking profanities at spectators - but even I was a little taken aback when I recieved an email from the registry reminding me to keep them informed of fundamental lifestyle changes.

Of particular importance is the guidance on making changes to your address, your name or gender and your programme of study, or how to interrupt or withdraw from your studies.

A note below the test results added, In subjective terms, this means you are predominantly heterosexual; only incidentally homosexual.

Honestly, I'm suprised that I'm as much as 15% gay. I'm bloody obsessed with men. Must be the influence of all them bisexuals I'm friends with.

Oh, and why is heterosexuality yellow? Do they make yellow Straight Pride awareness ribbons?

   Come, Madame, come, all rest my powers defie,
Until I labour, I in labour lye.
The foe oft-times, having the foe in sight,
Is tir'd with standing, though he never fight.
Off with that girdle, like heaven's zone glittering,
But a farre fairer world encompassing.
Unpin that spangled brest-plate, which you weare
That th'eyes of busy fooles may be stopt there.
Unlace your selfe, for that harmonious chyme
Tells me from you that now 'tis bed time.
Off with that happy buske, which I envye
That still can be, and still can stand so nigh.
Your gownes going off such beauteous state reveales
As when from flowry meades th'hills shadow steales.
Off with your wyerie coronet and shew
The hairy dyadem which on you doth growe.
Now off with those shooes, and then safely tread
In this love's hallow'd temple, this soft bed.
In such white robes heaven's angels us'd to bee
Receav'd by men; thou, angel, bring'st with thee
A heaven like Mahomet's paradise; and though
Ill spirits walk in white, we easly know
By this these angels from an evill sprite,
Those set our haires, these our flesh upright.
   Licence my roaving hands, and let them goe
Before, behind, between, above, belowe.
O my America! my new-found-land,
My kingdome, safeliest when with one man man'd,
My myne of precious stones, my empiree,
How blest am I at discovering thee!
To enter in these bonds is to be free,
Then where my hand is set, my seal shall be.
   Full nakedness! All joyes are due to thee,
As souls unbodied, bodies uncloth'd must bee
To taste whole joyes. Gems which you women use
Are like Atlanta's balls, cast in men's viewes,
That when a fooles eyes lighteth on a gem
His earthly soule may covet theirs, not them.
Like pictures, or bookes gay coverings, made
For lay-men, are all women thus arraid;
Themselves are mystick bookes, which only wee
(Whom their imputed grace will dignifie)
Must see reveal'd. Then since that I may knowe,
As liberally as to a midwife shew
Thy selfe; cast all, yea, this white lynnen hence,
Here is no pennance, much lesse innocence.
   To teach thee, I am naked first; why then
What need'st thou have more covering than a man.

John Donne 'To his mistris going to bed'
