Which of the following is the most significant limitation of fossils as a source of information about evolutionary history?
A) It is sometimes impossible to determine when a fossil organism lived.
B) The fossil record for many groups is fragmentary or even nonexistent.
C) Most fossils contain no nucleic acids or proteins and therefore are worthless for studies of molecular evolution.
D) It is impossible to determine if morphologically similar fossils belong to the same species, because one cannot know if the fossil species could have interbred.
E) Most fossils provide no information about the morphology of soft anatomical structures or about external characteristics such as color.
