Why do some plants' leaves turn yellow, whilst others turn red? Are there any any particular evolutionary advantages to chosing a particular color? 

In Autumn, (note spelling) actually they don't 'turn' yellow, red etc.

What actually happens is that the plant stops producing chlorophyl, which give plants their green colour and masks the colouring of any other chemicals.

As the chlorophyl dissipates the green fades away leaving tthe base colour.

Then the residual chemicals start to form darker sugars which make the leaves darken from yellow through orange, red and brown.
