Some molecular data place the giant panda in the bear family (Ursidae)but place the lesser panda in the raccoon family (Procyonidae). Consequently, the morphological similarities of these two species are probably due to
A) inheritance of acquired characteristics.
B) sexual selection.
C) inheritance of shared derived characters.
D) possession of analogous structures.
E) possession of shared primitive characters.

The morphological similarities between the giant panda and the lesser panda, despite their placement in different families based on molecular data, suggest that these similarities are due to analogous structures. Analogous structures arise from convergent evolution, where unrelated species develop similar traits independently, often due to similar environmental pressures or ecological roles, rather than from a common ancestor.
