Please explain

Can you walk me through this question?

Thanks for your question @Christy-Earls

The main point of passage A can be found in the final paragraph, beginning in line 19: "it appears that music and language evolved together as brain size increased over the course of hominid evolution. But...language, not music, was the primary function natural selection operated on." One of the facts offered in support of this claim is the differences in human behavior regarding language and music. Almost everybody can perform well at language, but the performance of music is often left to the specialists.

The main point in passage B is, beginning in line 32, that "the enjoyment of and the capacity to produce musical notes are faculties of indispensable use to mothers and their infants." The author then immediately goes on to that "it is in the emotional bonds created by the interaction of mother in child that we can discover the evolutionary origins of human music." In other words, the author is using the interactions of mothers and babies to support their claims about the evolutionary function of music.

In both cases, the authors are using modern day human behavior as evidence for their claims about the evolutionary origins of human abilities.

Hope this helps!

Hi! I understand why the answer is E (from post above), but I am confused how to even interpret what D was saying. I guess I am confused on what D means in more simple terms. Thanks!

D was "The discovery of the neurological basis of a human behavior constitutes the discovery of the essence of that behavior."
