Early biologists referred to animals as ''simple" and ''advanced," but now it is more accurate to use the following terms:
A) ''allopatric" and ''sympatric," since the species is most important.
B) "generalists" and ''specialists," since this is how biologists classify characters.
C) ''simple" and ''complex," since anatomy terms are more exact.
D) ''evolved" and ''un-evolved," since everything ties together with evolution.
E) ''primitive" and ''derived," since some early forms became very complex and some evolved forms are derived from them but lost characters and are simple.

Question

Using the terms "primitive" and "derived" is more accurate because it recognizes that some early forms may have become very complex and that some evolved forms may have lost characters and become simpler. This reflects the complexity of evolution and the importance of considering the full history of a species. Using terms like "simple" and "advanced" can be misleading and may not accurately reflect the true diversity and complexity of different animal species.
