Assertion 5.6: There are no transitional forms between whales and their landgoing ancestors.
Analysis:
Cell biologist Kenneth Miller relates:
By 1994, [Phillip] Gingerich and fellow paleontologists, including Hans Thweissen, had found not one, but three intermediate species [Pakicetus inachus, Ambulocetus natans, and Rodhocetus kasrani] linking land mammals to the archeocetes, the oldest swimming mammals. The midpoint of the series, a marvelous animal called ambulocetus natans (the "swimming whale who walks"), displayed exactly the combination of terrestrial and acquatic adaptations that critics of evolution had called impossible, even in principle. (Miller 1999:264)
