Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Analogous structures show common ancestry.
A
True
B
False
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -The given statement is False. Analogous structures are important biological structures. These structures have similar functions, but they do not have a common ancestry. They are all come from unrelated evolutionary lines.

Detailed explanation-2: -Analogous structures have different ancestry, but the same function. These can be thought of in terms of the literary device of “analogy, ‘’ where two different things are compared based on their similarities. Homologous structures have the same ancestry, but may no longer serve the same function.

Detailed explanation-3: -Vestigial structures are homologous to fully functioning structures inherited by related lineages. Thus, they provide strong evidence of common ancestry and can help us trace the evolutionary origin of the species with the vestigial structures.
