Occam's razor

The basic idea behind Occam's razor is simplicity.  With just about any problem,  the right answer is probably the simplest one.  This mentality seems to be overlooked in Darwin's theory of evolution.  Darwin was certain that the fossil record would reveal a gradual progression and development of various species. But the findings in the developing field of paleontology has not supported the theory.  The most recent paleontologists reject Darwin's theory as wrong.  The same scientists, instead of following Occam's razor, have posited the theory of punctuated equilibrium.  I won't go into the details of the theory, but suffice to say, it's ridiculous.
In my opinion, the most obvious, and simplest answer is that of big numbers.  I would suggest that the further one goes back in time, the more species one will find.  In other words, the reason we are finding so many unknown fossils is that there simply used to be many more species of animals.  Time and survival of the fittest has reduced the number of species to what we currently see.  The weaker species have gone extinct, while the stronger species have continued with us.  We see animals go extinct all the time.
I'm not a scientist, but my theory simply makes sense.
