Darwin-Hooker Letters : Letter from Darwin, C. R. to Hooker, J. D. on [8 Sept 1844]

Darwin, C. R.

Darwin-Hooker Letters

Acknowledges note and parcel for Ehrenberg. Considers why different areas have different numbers of species. Gives an example opposing Hooker's view that paucity of species results from vicissitudes of climate. Darwin has concluded that species are most numerous in areas that have most often been divided, isolated from, and then reunited with, other areas. Cannot give detailed reasons but believes that "isolation is the chief concomitant or cause of the appearance of new forms".
