Which of the following best defines "Homologous Structure"? Structures that are similar in different species because of common ancestry. These structures grow from the same embryonic tissue. Structures in different species that have similar functions but are structurally different. Like the shell of a turtle and shell of an armadillo. A structure that we no longer need but still have because our ancestors had it. Structures in different species that look alike.
