These missing links are the supposed in between species that show how one involved into another, but as far as geology and paleontology and such can tell us thus far, no missing links actually exist. Its all speculative.
I'm lol'ing over the fact that I'm interrupting this discussion on a thread about an animated football show, and your beliefs are your beliefs, but as a student of paleoanthropology I'd just like to point out that there's plenty
of evidence. Read up on Ardipithecus ramidus or the australopithecines sometime, it's pretty fascinating stuff.
