In a short span of time you've impugned one member's integrity in one thread, and now you raise the accusation of hypocrisy in this thread. If you can't play nice with the other children and follow rule 3 of the Forum Guidelines you won't be allowed to play here anymore.
Whales as well as protocetids had 5 toes. Hippopotamus has only 4 toes like all other eventoed ungulates. That would be an argument for creationists.
The evolutionary explanation would be a mutation that reactivated formation of the fifth lost toe in the ancestor to whales and protocetids after they split from the hippopotamuses. Or is it the case that the fifth toe actually hasn´t been completely lost?
The argument that a complete lineage must be shown to prove evolution is a specious argument. Several responses to this msg have demonstrated the difficulty of finding the lineage; however, the real proof of evolution is that evolution is a process which is readily observable and which we now understand suffienctly well to know how it works (mutations due to DNA copying errors when cells divide). Knowing how the evolutionary process works allows us to see how life evolved. The fact that there are "gaps" is equivalent to the problems geneologits have when birth and death records are destroyed during fires or other calamaties. But the lack of a complete geneological record doesn't bring into question the fact that members of a family had parents.
