o you have som DNA from fosils wh?? boy you are really good. Cience has been orking on that for two ecades and the closest theyve gotten (after an agreed upon length of time for degredation).
PS "some guy you call Crick" didnt discover DNA. James Watson and "Francis" Crick DID discover what it crytak structure was, and in doing so became two of the most decorated plagiarists in biochemistry.
Ive asked you to read several books including one about origins of the cetaceans. You would just give a snide comment about how you werent interested in that, so now youve become the purveyor of DNA evidence from the Paleogene.
till, you arent the king of BSers about DNA. e had a guy herein with a name of IONUS who tried to BS me that he could know about T rex from its DNA. So hi BS beat yours by at least 15 million years.
The issue of last common ancestor concept orks on step at a time. If you were up on that concept, youd have seen that Ambulocetus (wlking whale) was the first of a whol group of fossils that had "whale like" features in their middle ear, teeth, and nares. These features were then seen in a derivative daughter genus called ambulocetus, which, by retining ambulocetus fetures and adsing some new ones including mpre pddle like legs and a longer frame and subdued hip began to show more whale like features.
YOU seem to make the jumps from Ambulocetus without considering all the later genera that had whale like features.
There may have been more than 10 genera that approched "whaleness" a step at a time.
All these genera were becoming adapted to the fluvial environment of the shallow seas along the Indian and Mid east subcontinents marine environments. All these animls , through time, had a big thing in common besides their increasing amounts of body structures. They all lived in a relatively small area of the S Asian
environment(mostly grassland and forest margins along a series of estuaries, then, later, the marine environment begins to develop as estuaries grew into bays, then to full on shallow marine areas with thousands of islands (like the present South Pacific .
When these " evolutionary relationships" based on changing geology and changing fossils become hypotheses and then theories with good bases of evidence, its never done as a YAHOO "lets make up some ****". It took many a yer and was mostly a result of the growing facts of sea floor spreading and Continental drift.
When you get your references about Paleocene Proto-whale DNA, please let me see it cause I will kneel before you as a suppliant to your secret knowledge.
I am curious though, what do you provide as an explanation for the existence of whales (Remember they didnt appear as deep water sppecies until the late Oligocene, while several species of cetacens (like Zueglodons or "Basilosaurians" )
