Evolution doesn't have to be in huge leaps. That is one of the things that cretinists always get wrong with their "Why are there still monkeys?" bollocks. Evolution doesn't cease simply because a creature is extremely well adapted to its niche and has no need for major restructuring. Small aspects are evolving constantly.
Micro-evolution is occurring all the time - even in humans - we are a lot more resistant to bubonic plague than we once were, and asian flu, thanks to the millions that left the gene pool.
While it is true that the first, recognisable slime moulds evolved many hundreds of millions of years ago, it is not true that those that are around now have not evolved since.
That's just maintaining, IMHO. Not evolving. (Now comes the argument about what "evolving" means. )
