I want to know the answer to the following question:
How far back does Chapter One of On the Origin of Species go in its coverage of animal and plant species?
All the background I'm provided with is that "As an illustration of artificial selection, he describes fancy pigeon breeding, noting that "[t]he diversity of the breeds is something astonishing", yet all were descended from one species of rock pigeon.". Is that enough to answer the question?
Answer: no
