Before taking the train of thought that you have hopped on too far, The gedanken experiment was not to replicate the time line of evolution to prove that it exist. What was proposed was to step-wise change out genes from the human genome with those of the [bleep] (or vice versa) via in vitro gene transfer techniques and imagine what would be the result.
I suppose the real point was that even though the called for 1/2 dog-1/2 man chimeras are not obvious, ~90%-10% [bleep]-human chimeras exists and they post on this forum.
