" Think about the structure of our skeleton, for example, and the fact that land animals without endoskeletons are restricted in size. "

If you think about it.
That is as good an argument for intelligent design as it is for evolution. An intelligent designer would not create a land animal that could not walk the earth.

On the other hand evolution would predict that at some point in time in some places there may have been larger non vertebrate animals that were out-competed by vertebrates. If the fossil record showed that somehow, it would be a minor confirmation of evolution.

Absolute bollocks, Wacko. What a bloody lightweight you are. There is no "good argument" for intelligent design any more than there is a good argument for little green men on Mars and Christ knows why I'm having to tell you that. In addition, evolution does not "predict" anything, and your imagined scenario is just brainless tripe. Most of your posts are pretty inane, Wackers, but this one really takes the biscuit. Do try not to waste our time, eh?
