Interesting stuff.
"Who would have suspected that a handheld genetic test used to unmask sushi bars pawning off tilapia for tuna could deliver deep insights into evolution, including how new species emerge?"

    What is interesting is that Darwin noticed there were no 'in between' species and the genetic bar code seems to indicate the same thing. Stephen Hawking once stated that his math seemed to prove the need for a planned universe although he still didn't believe there is a God. Whether there is a creator or not religion disproves itself in its demands for servitude, enslavement, self sacrifice and fear of said supposed creator who is motivated by of love and caring for his creation!

    Ancient Aliens on the History Channel would snap up this football and run the whole 100 yards.
    Maybe they have. Me dino only watches bits of that show when channel surfing.

    It is interesting stuff.

    I suspect considerable confusion is introduced by the lack of definition and use of the term "animal". It seems to be used interchangeably with the term "species". What about sub-species? Federal invokers of the ESA often abuse this lack of distinction of species versus sub-species to beat people up.

    What about plant life? Many plants go way back or are these sub-species? Do single celled organisms have DNA? (I have no idea).

      If a engineer built with legos, no mater what he built, whether substantial or major, each variations would still be legos. Only when something not a lego is introduced to the lego construct does that thing stand apart, but it still is principally legos. :)

        Its well and good that someone took the point.
        Consider this: where did all the elements come from? Answer, collapsing stars and various stages of decay.

        The analogy holds.

    Sounds like What Moses wrote, all animals came into being according to their species. Pre-designed by an intelligence. .Humans did not evolve language or the ability to think and speak. Nor did animals evolve gradually from one species to another There was not enough time to do so.in under 200 thousand years.Also genetic diversity did not occur according to these findings. All are essentially the same as they began 100 to 200 thousand years ago.

    "The observed average duration of individual beings varies, from a few hours, as is exemplified in the minute world of life revealed by the microscope,--as in the Vorticella ramose, different species of Mucor, &c.,--to a few centuries, as is inferred to be exemplified in whales, elephants and forest trees. What naturalists call varieties, possess a duration extending, more or less well marked, through, perhaps four or five generations of individuals. Species, so called, have a much longer life. Concerning the average duration of species, nothing very reliable is known; perhaps a thousand successive individual generations might retain to the last, the essential specific characteristics."

    J. L. Riddell, M.D., Professor of Chemistry, Introductory Lecture, Delivered on November 18th, 1851, Before the Medical Class, University of Louisiana, New Orleans, “On Our Knowledge of Nature, the Natural Sciences, and certain Truths revealed by the Microscope."

      Not entirely sure how what you presented relates to the other. The finding in the article I presented for discussion suggests that everything tested resulted in data returned dating things to the same relatively small approximate period in time.

      "For the planet's 7.6 billion people, 500 million house sparrows, or 100,000 sandpipers, genetic diversity "is about the same," he told AFP."

      And not all evolved at the same pace or in the same way. While this says nothing conclusively it does suggest a reevaluation of premise when it comes to evolutionary theory in as much as gradual slight evolutionary changes occurring in all species over millions and millions of years.

      Starting at the same relative point in time, what is it about Man that makes him far more adaptable to his surroundings that allowed him to flourish and eventually dominate the earth? Why has man evolutionary process achived in ways every other species has not?
      Interesting info to consider.

        To answer the question, "Why has man evolutionary process achived in ways every other species has not?", I can only point to the choice to think and the consequential power of reason. As Ayn Rand put it, faced by a predator, animals perish while Man writes the Constitution of the United States.

        My point was only that the idea that species come and go was not original with Darwin. In Origin of Species Darwin opens by citing a dozen people who preceded him with the same basic theory. However, they all had flaws in their presentations or observations. Lamarck's theory was widely discounted on that basis. Today, epigenetics again raises the question of the extent to which environment shapes heredity.

        John Leonard Riddell was a capable American scientist of his time. Riddell wsa a botanist. He invented the binocular microscope.His work preceded Darwin's Origin and followed much of the same thinking on similar observations.
