In a five-year retrospective paper, its formulators defended it by emphasizing its relevance to the greater pattern the fossil record. It draws on Ernst Mayr's idea of parapatric speciation in the sense that geographic landscapes are translated into abstract fitness landscapes consisting of ridges and valleys. Its central idea is that an accumulation of genetic material or a sudden beneficial mutation may push a species to a higher level of evolution over a relatively short timescale. An opposing theory to phyletic gradualism, FTP, what is this evolutionary mechanism, first proposed by Stephen Jay Gould and Niles Eldredge in 1972?
