Trust, the underlying factor in a marriage cant be questioned when one's wife gives birth and the baby is a mirror image of the father. That was one of the determining factors used to establish the paternity of one's child, especially in olden times. But trust can be sabotaged. A woman can easily pin her pregnancy from an adultereous affair, on her unsuspecting husband. However, science is finally catching up with these unfaithful women as men, can now request through conventional means if a child is actually theirs, biologically or not. And in some cases, the old saying, "Only a woman knows the father of her child can easily be validated, not unless the woman had multiple relationships (Povich's show is an example)
But seriously, do you think that DNA has been more of a blessing than a pain? Larry Birkhead can always thank DNA for establishing paternity of her infant daughter, a slap to the cruel and malicious intentions of the mother (yeah, it was very malicious of Ms. Smith to have done so) to have presented her to another man. I am actually in awe that he went at great length to prove that he was the father. Others may have given up, besides, who can always be certain of their paternal rights?
On the other hand, read this story. http://www.nytimes.com/2007/04/10/us/10dna.html?_r=1&pagewanted=2&oref=slogin.
A man's attempt to bring in his children from Ghana ends in a tragedy, because DNA results came out to disprove his long held notion that only one of his four kids, he had invested financially and emotionally, like a dutiful father was his. Angst, despondence, a constant reminder that his late wife was unfaithful to him, perhaps in their marital life has weighed heavily on him, since he was presented with the results. His next move is to petition for them as their step-father. His only biological child from his late wife is in the states with him, while the the 'step-kids' , unaware of their true parternity are in Ghana, and wondering when they can join their 'father'.
If the DNA results had not been used, the Ghanaian would have gleefully believed that all those kids he had raised were actually his, and would have been excited in reuniting with them. DNA has only erased the pain, leaving behind a sense of betrayal. So, while the likes of Birkhead are rejoicing over the established paternity of their infant children, there are others, who are lamenting over the emotional void in their psyche due to the knowledge, courtesy of DNA that the children sired in one's marriage are not actually theirs biologically, but were products of an adulterous relationships.
Is the pain and angst associated with DNA really worth it, or do you consider it to be a blessing?
