- Selby cited Matthew's book many times in 1842 and then went on to edit Wallace's (1855) Sarawak paper - which Darwin also read pre 1858. Darwin and his friends knew Selby very well. Darwin sat on committees with him and his father and friends had even stayed at Selby's home - where Matthew's book sat in the library.
- Chambers cited Matthew's book in 1832 and then in 1842 wrote 'The Vestiges of Creation' the best seller on evolution that was Wallace's greatest influence and a great influence on Darwin for famously putting evolution "in the air" in the first half of the 19th century. Darwin was a friend and correspondent of Chambers. And Lyell was a member of the same Geological society as Chambers and heard him speak on more than one occasion. It is well known that both Darwin and Lyell knew that Chambers was the anonymous author of the heretical Vestiges.
'When we look to the individuals of the same variety or sub-variety of our older cultivated plants and animals, one of the first points which strikes us, is, that they generally differ much more from each other, than do the individuals of any one species or variety in a state of nature. When we reflect on the vast diversity of the plants and animals which have been cultivated, and which have varied during all ages under the most different climates and treatment, I think we are driven to conclude that this greater variability is simply due to our domestic productions having been raised under conditions of life not so uniform as, and somewhat different from, those to which the parent-species have been exposed under nature.'
