I saw at the History channel some times ago a similar film which showed how Nature restores the Earth to the pre-human state.
I thought about some questions which arise from a biological point of view.
Let's presume that the phenomenon is limited to the disappearance of the human race while other animals continue to live.
What could be the conditions to it:
1)A meteorite hits the earth in the same way as we presume that happened in the time of the
dynosaurus and destroys the minimal conditions needed for subsistance of humans.
In this case if small mamals ,like the strong resilient rats we know to day,continue to live, then in
the next 150-200 milions of years a new human race similar to us has good chance to reappear.
2)A pandemic bacterial desease exterminates all humans but spares animals.The future could be the
same as above.
3) The life supporting conditions for the whole fauna disappear but bacteria succeed to adapt
themselves to the new conditions.If the flora continues to subsist then the bacteria could enter an
evolutionary chain and revive the human race after some billions of years .
There could be also another succession of events if the flora disappears before the fauna ,a phenomenon which we partly see under our very eyes.
In this case a supplementary major cathastrophy hiting the remaining fauna has the chance to bring the earth to the state which it appears on other solar planetes.
These are all mental games but I wonder if the biologists of our forum coud find any interest in developing debates related to Darwinism, concerning this topic.

I hope History Channel in Europe will transmit this series soon.
