Question

Structures as different as human arms, bat wings, and dolphin flippers contain:

a) Analogous structures
b) Homologous structures
c) Vestigial structures
d) Mutations

Answer 1

Structures as different as human arms, bat wings, and dolphin flippers contain homologous structures, which are similar in related organisms because they were inherited from a common ancestor.

Step-by-step explanation:

Structures as different as human arms, bat wings, and dolphin flippers contain homologous structures. Homologous structures are structures that are similar in related organisms because they were inherited from a common ancestor. These structures may or may not have the same function in the descendants. For example, the bones in the front flipper of a whale are homologous to the bones in the human arm.
