My Year of Darwin: 8/16/2014 Speciation by degrees

 Charles Darwin


"I look at varieties which are in any degree more distinct and permanent, as steps towards more strongly-marked and permanent varieties; and at the latter, as leading to subspecies, and then to species" Darwin, Origin of Species 2nd edition

I'm wondering if he's thinking of a population that's going through this or two separate species or it it even matters.
