I want to know the answer to the following question:
What does Darwin do to show that his theory can support many theories that could not be explained by individual creation of species?
All the background I'm provided with is that "Darwin presents supporting facts drawn from many disciplines, showing that his theory could explain a myriad of observations from many fields of natural history that were inexplicable under the alternate concept that species had been individually created.". Is that enough to answer the question?
