The Covid lab leak theory is looking increasingly plausible

In March last year, it was widely agreed by everybody sensible, me included, that talk of the pandemic originating in a laboratory was pseudoscientific nonsense almost on a par with UFOs and the Loch Ness monster. My own reasoning was that Mother Nature is a better genetic engineer than we will ever be, so something as accomplished at infection and spread could not possibly have been put together in a lab.

Today, the mood has changed. Even Dr Anthony Fauci, the US President’s chief medical advisor, now says he is ‘not convinced’ the virus emerged naturally. This month a letter in Science magazine from 18 senior virologists and other experts — including a close collaborator of the Wuhan lab at the centre of the debate, Ralph Baric — demanded that such a hypothesis be taken seriously. Suddenly, too, journalists have woken up and begun writing articles admitting they might have been hasty in dismissing a lab leak as a Trumpian conspiracy theory last year.
