New biogeography book argues for chance survivals, not continental drift …

… based on the molecular clock (how fast evolution supposedly occurred), in accounting for odd dispersals of life forms:

A recent study of the evolutionary relationships of fossil primates highlights the profound influence of chance dispersal in a particularly obvious way. The phylogenetic placement of various groups in this study can be debated, but, if true, the results imply that, some 40 million years ago or earlier, an ancient primate species made an unlikely, accidental journey from Asia across the Tethys Sea to Africa, which was then an island (PNAS, 109:10293-97, 2012). Over many millions of years, those seafaring ancestors’ descendants evolved into diverse lineages, including baboons, guenons, mangabeys, and the monkeys that would go on to raft from Africa to the New World. Those ancestors would also give rise to gorillas, chimpanzees, Australopithecus, Homo erectus, and us. Given the massive impact of our species on the planet, this case, if it holds up, will rank as an extreme illustration of the profound influence of improbable, unpredictable ocean crossings on the history of life.

Apparently molecular clock claims have won out over continental drift claims, but see this from a Pearson text:

Some biologists are skeptical about the accuracy of molecular clocks because the rate of molecular change may vary at different times, in different genes, and in different groups. The judicial use of molecular clocks, however, may provide approximate markers of elapsed time. An abundant fossil record extends back only about 550 million years, and molecular clocks have been used to date evolutionary divergences that occurred a billion or more years ago. But the estimates assume that the clocks have been constant for all that time. Thus, such estimates are highly uncertain. [Colour emphasis added.] Excerpt.

So, “improbable, unpredictable,” meet “highly uncertain.” (There is no reason to trust any such estimates for any time period in the fossil record in the absence of constancy.)

Oh, and by the way, Darwinian evolution is supported by “mountains of evidence,” or “mountains and mountains of evidence.” Or is even“fact! fact! FACT!”[1] Most of the facts are just like these ones. Fun with ancient geography.

    Yes they do rely on biogeography and geology to make biological conclusions.
    Its called cheating in miniature golf.
    The primates locations on the planet always cause trouble for them.
    They need to get them evolving before they get them PLACED on far away continents from each other.
    so they must say they came from Asia and moved/swam to africa and then to south america.
    very unlikely trips.
    iN reality they came off the ark and moved easily into all the areas at the same time with no evolution but mere adaptation. Just like the people. We didn’t evolve into our colours and looks etc. it was fast and furious from innate triggers I say.
    the primates simply walked to south america in a warm migration soon after the flood. They simply survived , unlike the rest, because they lived in trees which were more rich in food.

    Evolutionists have New World Monkeys hopping across the Atlantic ocean, yet still make fun of Creationists for using similar explanations.

    And today, all over the internet, evolutionary arguments will be made based on “consistent molecular clock data.”

    How many evolution articles can you look up right now which contain as one of their lines of ‘evidence’: “Molecular clock data suggests…..

    What a crazy situation.
