The changes in species should be more analog if they were to have come from the same creature, but the changes are distict and rigid.

The changes were NOT distinct and rigid. Even if you are to accept the puctuated equilibrium version of natiral selection (like I do) the changes are still incredibly gradual and smooth. Punctuated Equilibrium has "sudden jumps" and "spikes" which occur over many thousands of years. These are only sudden jumps, in comparision with the gradualism version of natural selction.
If however you are referring to the fact that there should be in existence a continum of all possible species....cat-dogs, man-apes, tiger-lions, etc etc etc, then you don't understand how speciasation works.
If you are talking about gaps in the fossil record, then you don't understand how fossilization works.
