He was the youngest son of John Wilson, a gauze manufacturer, and his wife Margaret Sym, and was born at Paisley20 November 1794. His father having died during James's first year, the family moved to Edinburgh, where he was educated. In 1811 he began to study for the law, but his health was poor. Wilson joined the Wernerian Society when just 17. In 1816 Wilson visited the Netherlands, Germany, Switzerland, and Paris. He later returned to Paris to purchase Louis Dufresne's collection of birds for the museum of Edinburgh University; and helped to arrange them. In 1819 he visited Sweden, soon after which symptoms of lung disease appeared, and he resided in Italy during 1820–1821. In 1824 he married Isabella Keith, and settled down at Woodburn, Dalkeith near Edinburgh, where he wrote and worked on scientific pursuits. Losing his wife in 1837, he took a winter residence in George Square, Edinburgh. He purchased Woodville in south Edinburgh in 1838. In 1827 he was elected a Fellow of the Royal Society of Edinburgh, his proposer being Robert Jameson. From 1850 until death he was curator for the society. In 1841, with Sir Thomas Dick Lauder, he made a series of excursions round the coasts of Scotland, at the request of the Fisheries Board, to study the natural history of the herring. Other trips followed at intervals between 1843 and 1850, and fishing excursions inland. In 1854 he was offered but declined the chair of natural history in the Edinburgh University, vacated by the death of Edward Forbes. He died at Woodville House on Canaan Lane in Morningside, Edinburgh on 18 May 1856. He is buried in Dean Cemetery in west Edinburgh. The grave lies in the small central south section facing onto the main central path. It stands immediately in front of the more distinctive grave of his brother John Wilson.

Evolution
Wilson was one of the first to have used the term "evolution" in the context of biological speciation. In 1830, he used this term in a paper on the history of goat and sheep, he wrote: Wilson's use of the term predated Charles Lyell in 1832. Wilson had rejected the evolution of species for creationism.
