Description
Excerpt from Age and Area: A Study in Geographical Distribution and Origin of Species
Here, as elsewhere, it was soon evident that the current theories provided an explanation that was not only unnecessarily complex, but one that did not explain. As one of my critics words it, for some reason the plant has advantages which enable it to spread; and beyond that point we cannot go. Gradually it became clear to me that plants spread very slowly, but at an average rate determined by the various causes acting upon them, so that age forms a measure of dispersal when one is dealing with allied and similar forms.
