UH, no.
Not every species is represented equally in the fossil record anymore than every species is equally abundant at any given time. There are far more rats than people on earth today and far more people than elephants. If one were to examine the fossil record for today several million years in the future, you would see lots of human fossils and probably no elephants.
Back during man’s early genesis, there were very few humanoid individuals of any “species” roaming the earth, hence few fossils to retrieve - but we have enough to give us a very rough idea of what was going on. Besides, back then, the average humanoid was rather small in build and more likely the prey of some larger creature who ripped apart the carcass. And until the time of Neanderthals, we have found no record of formal burials.
The real truth is that you have enough pieces of bones of something to allow you to reach whatever preconceived conclusion you want.
