==== Analysis of comparative speciation concepts ====

Sutton's claim that Darwin and Wallace plagiarised evolution by natural selection from Matthew also has been refuted by Joachim Dagg,<ref name="Dagg2018">{{cite journal|last1=Dagg|first1=Joachim L|title=Comparing the respective transmutation mechanisms of Patrick Matthew, Charles Darwin and Alfred Wallace|journal=Biological Journal of the Linnean Society|volume=123|issue=4|pages=864–878|date=2018|doi=10.1093/biolinnean/bly003}}</ref>
<div style="margin:30px;text-align:justify;">[Wallace's] concept of lineage-adaptation as a sequence of extinctions of less fit and survival of fitter varieties and his gradualism put him closer to Darwin than to Matthew. But he emphasized environmental changes for differential extinction and some form of isolation for lineage-splitting and speciation, whereas Darwin's mature theory saw competition as a sufficient cause of divergence, differential extinction, lineage-adaptation and lineage-splitting. This is not to say that Darwin was right in this view and Wallace wrong. By current standards, they were both right and wrong in different respects (competitive vs. environmental selection, sympatric vs. allopatric speciation).<br />
The perspective emerging from this comparison shows at least four unique theories (Matthew, early Darwin, mature Darwin and Wallace), each interesting in its own right. Each theory integrated change in conditions, variability, competition and natural selection in ways that allowed for species transformation somehow. Apart from this similarity, the theories differ significantly from each other in the mechanisms underlying transformation. However, this difference does not lie in the struggle for survival and survival of the fittest, but in the way in which natural selection is integrated with variability, competition and environmental conditions. Transmutation is a convergent result of structurally different mechanisms.<br />
The similarity of Matthew's scheme to the theory of punctuated equilibria is equally superficial. Eldredge & Gould (1972) took Mayr's model of allopatric speciation and combined it with Wright's model of genetic drift in order to explain gaps in the fossil record as results of relatively swift evolutionary change in small and isolated populations. Although catastrophes can produce such populations they are not required, and the mechanism underlying the punctuated record is the drift within small and isolated populations, not the absence of competing species that would prevent species transmutation. Therefore, viewing Matthew (1831) as an anticipator of the theory of punctuated equilibria (e.g. Rampino, 2011) is as wrong as claiming his scheme identical to Darwin's or Wallace's.</div>
