You Are Reading a Scientific Paper Regarding the Relationships of the Anatomical

You are reading a scientific paper regarding the relationships of the anatomical and behavioral characteristics of chimpanzees and their implications for early hominid evolution.You note that the authors refer to human ancestors as hominids.This implies that the researchers are relying on:

A) cladistic classifications of chimpanzees and humans, as this is most appropriate for their research.
B) anatomical classifications of chimpanzees and humans, as this is most appropriate when looking at adaptation and anatomy.
C) genetic classification of chimpanzees and humans, hence their use of the term hominid to describe human ancestors.
D) both b.and c.
