Douglas Dewar (28 May 1875 – 13 January 1957) was a barrister, British civil servant in India, and ornithologist who wrote several books about Indian birds.
He wrote widely in newspapers such as The Madras Mail, Pioneer, Times of India and periodicals such as the Civil and Military Gazette and Bird Notes.
Douglas was born in London where his physician father Dewar practised at Sloane Street and Hampton Wick.
Although his early works on ornithology seemed to accept ideas of adaptation and selection, he later became a creationist and published a number of books and debates attacking evolution, and was the founding secretary-treasurer in the Evolution Protest Movement in 1932 along with Bernard Acworth and Lewis Merson Davies,[6] jointly known as the Acworth Circle.
His book, The Transformist Illusion published posthumously in 1957 attempted to show the failure of evolution using examples such as the infinitesimal probability of proteins arising out of random mixing, the fossil record, bird anatomy, blood group incompatibilities, and queried evolutionary claims in embryology and vestigial organs.
