Answer:
Homologous structures have the same ancestry, but may no longer serve the same function. For example, the bones that make up human fingers were inherited from an ancestor that's shared by all mammals.
Answer:
observational learning
Explanation:
Mirror neurons are the neurons present in the frontal lobes and are responsible for observational learning. The action potential fired by these neurons is identical when a person observes an action and when the same action is being performed by the person itself.
For example, watching a child when he scores good in the examination, a teacher can sense the pleasure felt by him. This is because the teacher imitates the child in her own imagination and plays out the consequences and thereby understands the feeling of the child.
