Question

structural evidence: choose the 2 letters (1 for the definition and 1 for the picture) that best represent homologous structures. structural evidence structure type description picture homologous structure analogous structure vestigial structure a. the various structures in different species having the same function but have evolved separately and do not originate from a common ancestor b. a structure in an organism that has lost all of most of its original function in the course of evolution c. the various structures in different species which appear similar in structure and provide evidence of descent from a common ancestor a b c d e f

Explanation:

Homologous structures are structures in different species that appear similar in structure and provide evidence of descent from a common ancestor. Option C describes this characteristic. Among the pictures, option E shows similar bone - structure arrangements (like in limbs of different vertebrates which is a classic example of homologous structures).

Answer:

C, E
