The originator of macroevolution by natural slection, Patrick Matthew (1831) wrote about what he coined the "natural process of selection", In part he explained as evolution by natural selection with regard to what he called a "power of occupancy". Matthew used this example to explain that a tree might in fact grow better outside its "natural" environment (the soil and climate in which it is found in nature) but is prevented from doing so by other tree species that would overwhelm it through having a "greater power of occupancy". And he backed up his claim with real examples, This point was picked up by Jameson, So much for the myth that Matthew never backed up his ideas with examples of observations from nature.
In 1854, the year after Jameson cited Matthew's original discovery, William Hooker (friend of Darwin, Mentor of Wallace, and father of Darwin's best friend Joseph Hooker) who was empowered to make such decisions for the East India Company from Kew, blocked his application for promotion. See my book Nullius in Verba for the fully referenced details.
Darwin and Wallace would later replicate Matthew's original prior-published ideas - including replicating his original explanatory analogies - and claim them as their own. To date, their deceptions have a greater power of occupancy in the literature than veracity, because Darwin's and Wallace's newly discovered lies about the non-existence of any prior-readership of Mathew's book are being strangled by a hostile environment known as The Darwin Industry.
The evidence to support this is in my latest peer reviewed article: http://www.nauka-a-religia.uz.zgora.pl/index.php/pl/czasopismo/46-fag-2015/921-fag-2015-art-05 where you can lean just how many people in fact did read Matthew's ideas (because they are newly discovered to have cited Matthew's book pre-1858) - and their relationshops to Dariwn and Walace - before that pair replicatred them in 1858.
