Well, there are simple organisms that have remained unchanged for billions of years, like diatoms, algae, sponges, amoebae, bacterias, yeasts, etc. And other things have evolved and then seemed to stop evolving like great white sharks and crocodiles which both existed before dinosaurs.
The whole point of evolution by natural selection is that organisms become better adapted to their environments over time. Natural selection therefore only takes place when an organisms environment changes so that it is not optimally adapted. Those organisms you listed are extremely well adapted to their environments already, and their environments do not change; although some members of those species may have moved to other locations where they were not very well adapted, and hence evolved; in other words some yeasts have evolved - but then obviously they aren't yeasts any more.
