Intelligence
Intelligence, mental ability, including learning ability, problem-solving ability, and the capacity for abstract thinking. There has been much debate as to whether intelligence is inherited or a product of the environment. The fact is that physical constitution may contain developmental potentialities, but the environment decides to what extent and in what ways these potentialities are realized. Heredity and environment interact to such a degree that a clear distinction between their contributions is often impossible.
