Among all the authors, revealed uniquely in Nullius, that I have discovered did both read Matthew's book and also influenced, directly, Darwin and Wallace - and/or influenced those who we know influenced them - are the following important naturalists.These three played major roles at the epicenter of Darwin's and Wallace's pre-1858 written work on natural slection theory:
A Note on Charles Lyell's Amazing (or not as the case may be) links to Matthew's 1831 book.
The fact that Loudon, Chambers and Selby, three out of only seven naturalists known to date to have definitely read NTA pre-Origin, played such dynamic roles at the very core of influence and facilitation of Darwin's and Wallace's published work on natural selection can have only one rational explanation—beyond seeking to explain it away as a coincidence upon coincidence upon coincidence pile-up. Namely that it is now established beyond any reasonable doubt that Matthew's discovery influenced both Darwin and Wallace. This finding alone means that Matthew's prior-published discovery and his influence on others undoubtedly fulfills, indeed surpasses, all the conditions, protocols and conventions of scientific priority, thereby satisfying all required criteria for Matthew to be awarded full priority over Darwin and Wallace.
