In this Article, owing to an error during the production process, the text: “a rapid increase in Ne between 500 thousand million years ago and 1 million years ago.”, should have read: “a rapid increase in Ne between 500 thousand years ago and 1 million years ago.”. The original Article has been corrected online.
