My point is simply that Mayr was anti-saltationist but also claimed that he laid the foundation for punctuated equilibria, such that they are obviously distinct items.T Ryan Gregoryhttps://www.blogger.com/profile/17028390880937952573noreply@blogger.comtag:blogger.com,1999:blog-37148773.post-79505115326392015422008-01-25T17:44:00.000-05:002008-01-25T17:44:00.000-05:00I assume 'punctuated equilibria' and the like goes...I assume 'punctuated equilibria' and the like goes down a treat with the ID community.Timothy V Reeveshttps://www.blogger.com/profile/03913020911593893925noreply@blogger.comtag:blogger.com,1999:blog-37148773.post-43331417142977464502008-01-25T17:02:00.000-05:002008-01-25T17:02:00.000-05:00The problem with Mayr is that he said so many, oft...The problem with Mayr is that he said so many, often contradictory, things that he can take credit for almost anything. <BR/><BR/>If his idea was so important then why does has have to go back and quote mine his own work to find the key sentences?

It's especially curious to see claims that Mayr ruled out saltationism, and presumably by extention punk eek, when he considered himself (with just cause) as an early originator of the latter.<BR/><BR/><I><BR/>I believe I was the first author to develop a detailed model of the connection between speciation, evolutionary rates, and macroevolution (Mayr, 1954). Although long ignored, my new theory of the importance of peripatric speciation in macroevolution is now widely recognized. "Mayr's hypothesis of peripheral isolates and genetic revolution must of necessity be a centerpiece of the punctuated equilibria theory; it is the theory, for all practical purposes" (Levinton, 1983:113). I once more presented my theory in great detail (Mayr, 1963:527-555). Under these circumstances it is most curious that the theory was completely ignored by paleontologists until brought to light by Eldredge and Gould (1972).<BR/><BR/>Mayr, E. 1992 Speciational evolution or punctuated equilibria.
