It seems to be untrue because organisms aren't ordered that well. Look at human beings, for example. Wisdom teeth are there because our more primitive ancestors had much larger lower jaws, so the wisdom teeth fit in. Now that human jaws are much smaller, there is no room and many people are forced to have the teeth removed to avoid infection. Our tail bone is also a useless part of our anatomy that is a remnant of our more primitive ancestors as well, as we used to have tails long ago, but have evolved away from them. These are just two examples from many, but they seem to show that organisms (human beings specifically) are not "ordered" in the way that you claim.
This, along with the FACT that well-over 90% of this planet's species have died out throughout history, seems to point to a great deal of chance being involved. My question is how, specifically, do you reconcile this with your claim that organisms were chosen as is? Before, you merely ignored this point, so I would appreciate it if you could actually address it.
