Speaking of which, Barry Arrington goes into insane denial mode. http://www.uncommondescent.com/intelli....al-mode |
One of the many interesting aspects about reading Darwin is realizing how many aspects of modern evolutionary thinking he actually anticipated, even if he did not always recognize the significance at the time. The dude was an astonishing genius. |
Comparing the various editions resolved the issue.
Quote | Darwin, Origin of Species 1866: It is a more important consideration, clearly leading to the same result, as lately insisted on by Dr. Falconer, namely, that the periods during which species have been undergoing modification, though very long as measured by years, have probably been short in comparison with the periods during which these same species remained without undergoing any change. We may infer that this has been the case, from there being no inherent tendency in organic beings to become modified or to progress in structure, and from all modifications depending, firstly on long-continued variability, and secondly on changes in the physical conditions of life, or on changes in the habits and structure of competing species, or on the immigration of new forms; and such contingencies will supervene in most cases only after long intervals of time and at a slow rate. These changes, moreover, in the organic and inorganic conditions of life will affect only a limited number of the inhabitants of any one area or country. http://darwin-online.org.uk/Varioru....66.html |
That should settle that.
Note that Darwin doesn't only indicate that stasis occurs, but explains why it should occur, all while touching on allopatric speciation.
-- ETA: It may read more accurately as sympatric speciation. Close but no cigar for Charles.
ETA: Peripatric speciation perhaps. Maybe a cigarette for Charles.
