Are Cheaters 'Born That Way?'
One of the most acclaimed novels of all time, "Anna Karenina" by Leo Tolstoy, deals with the all-too-human failure of infidelity.
Tolstoy painstakingly draws out the circumstances and consequences of his characters' failings. And he delves into the interior life of his doomed protagonist. For instance, Tolstoy tells us that the more Anna grew disenchanted with her husband, the larger his ears looked to her.
As it turns out, Tolstoy needn't have bothered with all this detail. All he needed to do was to wait for science to reduce the conundrum of infidelity to a simple acronym: DNA.
