So the correct answer here is actually A, but it's really hard to spot so I think I'll list why the rest are wrong first.

B is incorrect as niksworth mentioned and the proof of this can be found in the "transition between paragraphs" section, i.e. last sentence of paragraph 1 and first sentence of paragraph 2.

C is also incorrect because of the third paragraph, where we find out that before Darwin, there were scientists willing to accept evolution.

Again, as niksworth pointed out, the reasoning behind eliminating D is in paragraph 4.

Eliminating E takes a bit of attention to detail that I myself lacked... The clue to this is in the last sentence of the second paragraph: "Behind Noam Chomsky's theory that there is an inherited deep structure of language, one can see a creationist view of the universe. " This means that Chomsky's theory is consistent with creationism, a religious view of the birth of the human race.

Now, why A is wrong: in the sentences

Debate centered on the question of what it was that made the human mind qualitatively different, and not whether it was qualitatively different at all. Language-using apes have eroded that earlier notion and also exposed uncertainty over the proper definition of human intellectual abilities.

The fact that we have "qualitatively" there suggests that there is no qualitative difference between the human and the animal mind. However, that doesn't necessarily mean that there are no other (non-qualitative, maybe quantitative?) differences between the two.
