A husband and wife go to a fertility clinic. As part of the treatment process, the clinic takes DNA samples from both of them and discovers that they are, in fact, fraternal twins.
It's a story seemingly guaranteed to go viral, and it soon made its way onto websites around the world. The Daily Mail covered it, as did Lad Bible, Elite Daily, The Independent's Indy100, Huffington Post Germany, and even websites as far away as India, New Zealand, Nigeria, and Israel.
They all pointed back to the same source: an April 12 story in the Mississippi Herald. Some referred to the Herald as a newspaper, but there's no print publication by that name, and the MississippiHerald.com domain was only registered in November. The reality is the story is a complete fabrication, and the Herald is part of a network of fake
local news sites that recently began pumping out hoaxes. But the site's utterly dubious origin didn't stop large, legitimate news sites from spreading its hoax to a global audience.
At a time when the media, governments, and other entities are supposed to be on alert for fake news, this example shows how a completely false story can still easily end up on major news websites. Many of the stories remain uncorrected as of this writing, though some sites that initially fell for it have updated their stories.
