I'm unclear about the point you are making with these pictures, Mark. The pictures are from different species. It is funny that they call the top one a whale - because it is supposed to be a part of the whale lineage. That would be like calling an australopithecus skeleton a "human" - because it is supposed to be a part of the human lineage. This use of terms only serves to try to reinforce their position.
Point being is that they have an adjusted narrative concerning how they think whales evolved. But you are right what they basically did was to match fossils with some similarities in sequence and then claim that the one is the ancestor of the other. This is innuendo at best.
