I want to know the answer to the following question:
How did Wallace claim that patterns in the distribution of species could be explained?
All the background I'm provided with is that "Charles Lyell recognised the implications of Wallace's paper and its possible connection to Darwin's work, although Darwin did not, and in a letter written on 1–2 May 1856 Lyell urged Darwin to publish his theory to establish priority.". Is that enough to answer the question?
Answer: no
