The reason these little creatures defy evolution is because they are out to out survive any and all life on this planet. This show that even the most simplest life forms can obtain an ability that does not require evolution. Which is why the question arises: If humans evolved from primates, as the human evolution chart says, why are primates still around?
Being able to survive = no reason to evolve. But evolutionists will avoid the question by saying: You don’t understand evolution, we both have a common ancestor. Yet the human evolution chart still hangs around.
