He considered this ‘species’ the ancestor of several large domesticated chicken breeds and believed it was one of six wild ancestral species of domestic fowl. Temminck's hypothesis was rejected by Blyth who thought Red Junglefowl G. gallus was the sole ancestor. The arrival into Britain of several very large Asian chicken breeds in the mid-19th century led to speculation that Temminck's G. giganteus may have been their wild ancestor. Darwin, who had initially agreed with Blyth, noted several peculiarities in the Cochin, a large Asian breed, which he concluded might not have been achieved by selective breeding, and questioned whether G. giganteus was involved in their ancestry. Temminck's giant junglefowl appeared to be a significant hurdle for Darwin in his effort to prove a single ancestral origin for domestic chickens.enopenAccesshttps://creativecommons.org/licenses/by-nc/4.0/Journal ArticleBulletin of the British Ornithologists’ Club2021-02-091403Domestic fowlsAncestral speciesPolyphyletic origin theoryMonophyletic origin theoryCochin China fowlCoenraad Jacob TemminckEdward BlythCharles Darwin
