"He submitted this extraordinary and graphic account of sexual behaviour of the adelie penguins, which the academic world of the post-Edwardian era found a little too difficult to publish," Mr Russell said.

The shocked polar explorer's associates in Britain determined that the "depraved" sex acts of the penguins was unnatural and so they buried the report for 100 years. How could anything that a creature of nature do be unnatural? How arrogant is man to assume he can judge anything he sees.
I imagine the same good chuckle will be had 100 years from now when people look back at how they viewed LGBT people today.
