Century-old Antarctic journal reveals survival and sexed-up penguins

Scott expedition notebooks acquired by Natural History Museum hold 'crucial data'

Detailed century-old observations of penguin behaviour, including sexual activity so depraved and shocking it was recorded in Greek alphabet code, have been acquired by the Natural History Museum.

Curators at the museum announced the purchase of original manuscript notebooks made by the explorer George Murray Levick, part of Robert Falcon Scott's ill-fated Terra Nova expedition to the Antarctic in 1910-13.
