Who’s the daddy?
Paternity can now be verified by a simple test – but that doesn’t mean it should be

It’s a wise child, they say, that knows its own father. Nowadays, however, wisdom is hardly required; DNA tests can do the job with scientific certainty. For the entire course of human history, men have nursed profound, troubling doubts about the fundamental question of whether or not they were fathers to their own children; women, by contrast, usually enjoyed a reasonable level of certainty about the matter. ...

...By contrast, the old situation, in which women presented men with a child, and the man either did the decent thing and offered support, or made a run for it, allowed women a certain leeway. The courtesan in Balzac who, on becoming pregnant, unhesitatingly sought, and got, maintenance from two of her men friends, can’t have been the only one. Uncertainty allows mothers to select for their children the father who would be best for them....

...Our generation sets a good deal of store by certain knowledge. And DNA tests have obvious advantages when it comes to identifying less happy elements of our heredity: congenital disease, for instance. But in making paternity conditional on a test rather than the say-so of the mother, it has removed from women a powerful instrument of choice. I’m not sure that many people are much happier for it.
