So now we not only have the technical means to fool our selfish genes, we have excellent rational reasons to thwart it, except in the special case where two people want to make a baby in the expectation that they will provide it a warm and welcome family shelter until it matures. The future belongs to multicultural countries, like the USA, rather than to culturally defensive states like Serbia. Globalization is upon all of us, whether we like it or not. If he doubts whether her baby is his, and feels strongly enough about it, he can run a DNA test. Meanwhile other scientific breakthroughs make it possible for a woman to have a baby from the sperm of an anonymous donor, or a dead one for that matter.
Infertile women can carry and give birth to a child from another woman's egg.
Such developments make it harder and harder to maintain the old-fashioned paternity fixation which undergirded traditional family values. There are too many new variations on the age-old theme. We need them just as much now as our forebears did. But when there is a third party, a spouse or another loved one, who may be hurt more or less deeply, this factor must be carefully evaluated before any decision is taken to go ahead with the liaison. If necessary, seek the advice of friends or professional counselors.
