Which is an example of a structural homology that indicates common ancestry? o leg of a centipede and leg of a lizard o antenna of a butterfly and eyes of a newt o mammary glands of an orangutan and mammary glands of a whale o teeth of a leopard and claw of a shrimp

The correct answer will be option-mammary glands of an orangutan and mammary glands of a whale

Explanation:

Homology is the pattern of the evolution which states that the organisms have originated and diversified from a common ancestor.

The organisms which exhibit the same structural structures but they may perform the same or different functions depending on the environment are known as homologous structures.

In the given question, since both orangutan and whale are both mammals and they possess mammary glands which perform the same function. Therefore the are homologous organs.

Thus, the selected option is the correct answer.

answer:

sequence 1- deletion

                  2- duplication

                  3- insertion

                  4- substitute

                  5- inversion

a- all cells come from pre-existing cells
