Why do you move so quickly away from those last two frames (what we can see directly)? Why not extract some directly observed numbers from them and project to see what results? How well does it match the fossil record of life's rate of progress? It sure beats just presuming that evolution's rate of progress was whatever it had to be to match the record. Such reasoning has a rather circular quality to it, don't you think?
The fossil record is directly observed.
Again, I have to point out that it appears you have never taken a science class.
