I want to know the answer to the following question:
Who convinced Darwin that his book needed a shorter, more compelling title?
All the background I'm provided with is that "An abstract of an Essay on the Origin of Species and Varieties Through natural selection, but with Murray's persuasion it was eventually changed to the snappier title: On the Origin of Species, with the title page adding by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life.". Is that enough to answer the question?
Answer: yes
