"The Lost World" Title

I am currently reading the classic novel "The Lost World" by Sir Arthur Conan Doyle. The novel's title, "The Lost World", is appropriate to the themes of the book. Arthur Conan Doyle chose an appropriate title based on the main setting of the book. The majority of the book takes place in the remote amazon following the footsteps of Professor Challenger's expedition. When the characters are not on their journey in this uncharted land they are speaking of its existence and planning their own expedition to test the theories and findings of Professor Challenger. During his previous expedition Professor Challenger discovered the possible proof for his evolution theories, a hidden piece of land containing creatures once thought to be extinct. This remote area in the South American Amazon is a mysterious world to mankind. "The Lost World" suits the novel because Professor Challenger has found a strange plateau where antiquated creatures thrive. These creatures of massive size and prehistoric nature resemble nothing of the creatures found anywhere else in the world. Professor Challenger's expedition revealed an area of undiscovered and untouched landscape. This piece of land possesses secrets to evolution and extinction. Before having been discovered this area of land was lost and unknown to mankind. The creatures and organisms found on this rare and hidden plateau contain the lost links to many phenomenons previously unknown by science. Professor Challenger's dangerous Amazon is truly a lost world.
