I want to know the answer to the following question:
How many copies of On the Origin of Species were created in the first printing?
All the background I'm provided with is that "The third edition came out in 1861, with a number of sentences rewritten or added and an introductory appendix, An Historical Sketch of the Recent Progress of Opinion on the Origin of Species, while the fourth in 1866 had further revisions.". Is that enough to answer the question?
Answer: no
