The butterfly effect: How a cheeky doodle in Utrecht led to the invention of DNA testing

In issue #19 of Delayed Gratification we connect the historical dots between a nineteenth-century act of mischief and a payout of $2.2 million to two employees wrongly accused of making a dirty protest around their employer’s warehouse. Along the way we also show why a genetic scientist at the University of Leicester systematically daubed his lab in his own blood.
