People need to understand the flawed thinking behind a "succesful species" and species owning their niche so that they "don't have the need to" evolve into something else.
Let's look at bacteria again. I acknowledge they are highly successful. They own tons of niches! We all accept this. But, here's the thing - the one bacteria, or the little isolated population of bacteria behind a certain rock, or in the stomach of a rabbit, or whereever, for that particular isolated population it doesn't matter if bacteria as a group of organisms are successful or not! You don't know if that particular population is successful right there, right now! They might not be. You must realize that every single bacteria is an independent entity, every single one of them has the potential to break away from it's current niche and conquer another one. You can't deny these guys the same chance to diversify under the exact same rules that you base the evolution of all life resulting in extreme variation of life on earth. There's always a niche out there to be conquered for any individual or group of individuals! There's always environmental factors at work against every individual, selecting and giving potential for an individual or population to mutate and evolve into something different.
It annoyes me that evolutionist are so blind to this fact. And I meet the same flawed thinking every time.
