[QUOTE="PlunkettsGhost, post: 64449, member: 198"] [B]Proposed Origins of The Whale - Part One[/B] It's a detailed subject, so you will have to excuse the long posts. These are from notes I composed some time back, in order to get a better sense of the nonsense for myself: I would like now to expose the very shaky foundations on which the supposed whale Family tree Lies. 1966 was the year it was first tentatively proposed that Archaeocetes, a supposed early precursor to whales, evolved from Mesonychids, an ancient carnivorous Land animal. Both Dissacus and Ankalagon were the only mesonychids known at the time and were thought too well developed evolution wise to be anything other than a sister group the the archaeocetes. Three more genera of middle Paleocene mesonychids have since been identified but consist only of fragmented cranium pieces. One also has lower jaw fragments(Hukoutherium). However no one has suggested any of these genera for ancestor of the archaeocetes, and thus [I]mesonychids [/I]continue to be classified as a "sister group" to the archaeocetes. In 1997 one Robert L. Carroll, in his book, [I]Patterns [/I]and Processes of Vertebrate Evolution, stated: [I]"It is [B]not [/B]possible to identify a sequence of mesonychids leading directly to whales".[/I] In actuality It is not even possible to identify a single ancestral species. Mesonychids are excluded from the actual chain of descent by the evolutionary criteria. Evolutionists believe that mesonychids evolved into archaeocetes, despite the inability to identify any species in the actual lineage, because mesonychids and archaeocetes have some surface similarities.
