I want to know the answer to the following question:
Who did Darwin write his ideas to in 1842?
All the background I'm provided with is that "Darwin began correspondence about his theorising with the botanist Joseph Dalton Hooker in January 1844, and by July had rounded out his "sketch" into a 230-page "Essay", to be expanded with his research results and published if he died prematurely.". Is that enough to answer the question?
Answer: no
