A National University of Singapore. study has traced historical shipping records and vindicated Darwin from accusations of deceit.

For the past four decades, Charles Darwin had been accused of keeping the essay of fellow naturalist Alfred Russel Wallace for a fortnight, thereby enabling him to revise elements of his theory of evolution, before jointly announcing the theory of evolution by natural selection in July 1858. Just recently, two researchers from the National University of Singapore (NUS), supported by a private donation, reconstructed the route taken by Wallace's letter to Darwin from Ternate and provided evidence that Wallace sent the letter a month later than historians had always assumed, thus clearing Darwin of the accusations against him.
