Question

Homologous structures such as the bones in wings, flippers, and arms are most closely concerned with Select one: a. comparative anatomy. b. biogeography. c. the fossil record. d. comparative embryology. e. comparative biochemistry.

Answer 1

a. comparative anatomy

Step-by-step explanation:

Comparative anatomy is a tool in evolutionary biology that is used in establishing how different organisms share a common ancestor by studying the similarities and differences in their anatomical structures. One major type of structure under consideration when employing comparative anatomy in finding out if different organisms share a common ancestor or not is homologous structure.

Homologous structures are similar structures that are found in different organisms. These structures appear similar in arrangement and configuration in different organisms. For example the bones in wings of birds, flippers of dolphins, and arms of humans have similar configuration, which give a clue that they share similar ancestral origin.

Answer 2

a. comparative anatomy.

Step-by-step explanation:

Comparative anatomy is employed in studying the similarities and differences of tissues or organs which originate from similar cells, have similar structures and are located in similar portions of the body. For example, flippers, arms, wings of bats and wings are homologous structures which likely develops from similar cells, comparative anatomist will be interested in studying their differences and similarities.
