Question

structural evidence: choose the 2 letters (1 for the definition and 1 for the picture) that best represent analogous structures.

structural evidence

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:

Analogous structures are defined as structures in different species that have the same function but evolved separately and do not come from a common ancestor (which is what option A describes). Looking at the pictures, picture F shows wings of different species (butterfly and bat) which are analogous as they have the same function (flight) but different evolutionary origins.

Answer:

A, F
