That concept has already been explored in a literature work of the 1930's called
Last and First Men: A Story of the Near and Far Future is a "future history" science fiction novel written in 1930 by the British author Olaf Stapledon. A work of unprecedented scale in the genre, it describes the history of humanity from the present onwards across two billion years and eighteen distinct human species, of which our own is the first. The book employs a narrative conceit that, under subtle inspiration, the novelist has unknowingly been dictated a channelled text from the last human species.
Stapledon's conception of history follows a repetitive cycle with many varied civilisations rising from and descending back into savagery over millions of years, as the later civilisations rise to far greater heights than the first. The book anticipates the science of genetic engineering, and is an early example of the fictional supermind; a consciousness composed of many telepathically linked individuals.

The earth becomes unfit to live on and through genetic engineering another species is created to be able to cope with the environment of the new planet the go to.
