UK - New research suggests the Polynesians, Europeans and the Chinese have had a penchant for black pigs because of the novelty of their colour. Scientists led by Professor Greger Larson from Oxford examined the DNA sequences of modern feral Hawaiian pigs and discovered that a novel mutation is responsible for their black coats, a significant finding because the pigs were expected to have either the Asian or the European genetic mutation leading to their black colour.A study has said wild pigs would naturally have camouflaged coats. However, human societies have independently selected domesticated pigs that express the trait of black-coloured coats.

　　新的研究表明，由于黑猪新鲜的颜色，波利尼西亚人、欧洲人和中国人对黑猪有一种偏爱。以牛津大学Greger Larson教授为首的一群科学家对现代夏威夷野猪的DNA序列进行了检测，并得到一个重要发明，黑猪的黑色外表是因为基因突变而来。科学家预计这个结果是由于亚洲猪的基因突变，又或者是欧洲猪的基因突变导致。研究称野猪与生俱来就有伪装的外表，然而人类社会自己作出选择，驯化了这种具有黑色外表特征的猪。
