Full Course Lesson 10, Passage 9, Q 8

[sarae]

The passage mentions that "the idea of neurogenesis in the adult mammalian brain is STILL not generally accepted..." (lines 48-49). I think this implies that there is still room for improvement for the theory. Why can't that be described as answer choice B, "progressive?"

[Steve Stein]

Hey sarae,

I think you brought up a relevant quote--the fact that the idea is still not generally accepted would point to a characterization of the current understanding as incomplete.

I hope that's clear--please let me know whether I have answered your question--thanks!
