You are again citing Conservapedia, a totally unreliable source. Furthermore, there is very strong reason to disagree with Mayr and Lewin.My response to you:
As Dr. Roger Lewin commented after the 1980 University of Chicago conference entitled “Macroevolution”:
“The central question of the Chicago conference was whether the mechanisms underlying microevolution can be extrapolated to explain the phenomena of macroevolution. … At the risk of doing violence to the positions of some of the people at the meeting, the answer can be given as a clear, No.” [Emphasis added]
Dr. Roger Lewin, “Evolution Theory under Fire,” Science. Vol. 210, 21 November 1980. p. 883-887.[91]

In 1988, the prominent Harvard University biologist Ernst Mayr wrote in his essay Does Microevolution Explain Macroevolution?:
“ Among all the claims made during the evolutionary synthesis, perhaps the one that found least acceptance was the assertion that all phenomena of macroevolution can be ‘reduced to,' that is, explained by, microevolutionary genetic processes. Not surprisingly, this claim was usually supported by geneticists but was widely rejected by the very biologists who dealt with macroevolution, the morphologists and paleontologists. Many of them insisted that there is more or less complete discontinuity between the processes at the two levels—that what happens at the species level is entirely different from what happens at the level of the higher categories. Now, 50 years later the controversy remains undecided.
...In this respect, indeed, macroevolution as a field of study is completely decoupled from microevolution.[92]
