I want to know the answer to the following question:
When was the first American edition of On the Origin of Species published?
All the background I'm provided with is that "In the United States, botanist Asa Gray an American colleague of Darwin negotiated with a Boston publisher for publication of an authorised American version, but learnt that two New York publishing firms were already planning to exploit the absence of international copyright to print Origin.". Is that enough to answer the question?
Answer: no
