there is plenty of evidence now that the organelles of cells were likely at one time were independent cells in their own right. so the mitochondria and chloroplasts (as two examples) were at one time likely were bacteria that somehow managed to get incorporated into other cells. this shows how life went from more simple forms to more complex and then if you look a bit closer you find that parts of the mitochondria DNA was taken into the DNA of the cell itself so it is also simplifying too. they are competing forces as the larger more complex a cell is the more energy it requires so eventually if there are optimisations that can happen the cell that uses less will win out over those that use more...

life is facinating... :)
Well my eyes got glassy and this went over my head! haha
