I want to know the answer to the following question:
Which scientist was addressed the most often in the new chapter of On the Origin of Species?
All the background I'm provided with is that "In the sixth edition Darwin inserted a new chapter VII (renumbering the subsequent chapters) to respond to criticisms of earlier editions, including the objection that many features of organisms were not adaptive and could not have been produced by natural selection.". Is that enough to answer the question?
