I remember that the short begings with a cork in the space , the cork turns into a yin yang and then becomes a planet, in the planet the creatures begin to evolve until they reach the modern age, and begin to destroy everything  at the end an excavator reachs the cork pulling it out finishing with the planet, the cork floats in the space and the cicle begins again.

I saw this short when I was I child on TV in the 90’s on a cultural channel in Mexico, I dont think that this short is from that date but it could help , it was in color
