Plague bacteria existed 20 million years ago?

From ScienceDaily:

Bacteria in ancient flea may be ancestor of the Black Death

About 20 million years ago a single flea became entombed in amber with tiny bacteria attached to it, providing what researchers believe may be the oldest evidence on Earth of a dreaded and historic killer — an ancient strain of the bubonic plague.

If indeed the fossil bacteria are related to plague bacteria, Yersinia pestis, the discovery would show that this scourge, which killed more than half the population of Europe in the 14th century, actually had been around for millions of years before that, traveled around much of the world, and predates the human race.

Talk about stasis. One wonders what it was doing in the meantime.

These findings are in conflict with modern genomic studies indicating that the flea-plague-vertebrate cycle evolved only in the past 20,000 years, rather than 20 million. However, today there are several strains of Yersinia pestis, and there is evidence that past outbreaks of this disease were caused by still different strains, some of which are extinct today.

While human strains of Yersinia could well have evolved some 10,000 to 20,000 years ago, Poinar said, ancient Yersinia strains that evolved as rodent parasites could have appeared long before humans existed. These ancient strains would certainly be extinct by now, he said More.

We shall see. There is no shortage of rodents n the world.

    “About 20 million years ago a single flea became entombed in amber with tiny bacteria attached to it”

    Dr. Cano’s work with amber bacteria, and Dr Vreeland’s work with salt crystal bacteria, goes back much further than 20 million years ago:

    “Raul J. Cano and Monica K. Borucki discovered the bacteria preserved within the abdomens of insects encased in pieces of amber. In the last 4 years, they have revived more than 1,000 types of bacteria and microorganisms — some dating back as far as 135 million years ago, during the age of the dinosaurs.,,, In October 2000, another research group used many of the techniques developed by Cano’s lab to revive 250-million-year-old bacteria from spores trapped in salt crystals. With this additional evidence, it now seems that the “impossible” is true.”

    The stasis exhibited in the ancient Bacteria was extreme and created quite a stir among Darwinists.

    The Paradox of the “Ancient” (250 Million Year Old) Bacterium Which Contains “Modern” Protein-Coding Genes:
    “Almost without exception, bacteria isolated from ancient material have proven to closely resemble modern bacteria at both morphological and molecular levels.” Heather Maughan*, C. William Birky Jr., Wayne L. Nicholson, William D. Rosenzweig§ and Russell H. Vreeland ;
    http://mbe.oxfordjournals.org/...../19/9/1637

    The ancient bacteria were so similar to modern bacteria that, even though extreme caution had been taken to prevent contamination, skeptics said that the samples must have been contaminated. That objection was refuted with the finding of ancient DNA sequences that were totally unique.

    World’s Oldest Known DNA Discovered (419 million years old) – Dec. 2009
    Excerpt: But the DNA was so similar to that of modern microbes that many scientists believed the samples had been contaminated. Not so this time around. A team of researchers led by Jong Soo Park of Dalhousie University in Halifax, Canada, found six segments of identical DNA that have never been seen before by science. “We went back and collected DNA sequences from all known halophilic bacteria and compared them to what we had,” Russell Vreeland of West Chester University in Pennsylvania said. “These six pieces were unique”,,,

    Moreover, according to the fitness test I asked Dr. Cano about, the ancient bacteria are more fit than the modern bacteria:
    In reply to a personal e-mail from myself, Dr. Cano commented on the ‘Fitness Test’ I had asked him about:

    Dr. Cano stated: “We performed such a test, a long time ago, using a panel of substrates (the old gram positive biolog panel) on B. sphaericus. From the results we surmised that the putative “ancient” B. sphaericus isolate was capable of utilizing a broader scope of substrates. Additionally, we looked at the fatty acid profile and here, again, the profiles were similar but more diverse in the amber isolate.”:

    Thus according to the fitness test of Dr. Cano, the change witnessed in bacteria over extremely long time periods conforms to Dr. Sanford’s Genetic Entropy model; i.e. a loss of functional information/complexity, since fewer substrates and fatty acids are utilized by the modern strains than by the ancient strains.

    Moreover, a genetic study has shown that bubonic plague (Black Death) was caused by loss of genes and streamlining (genetic entropy) of a non-pathogenic bacteria:

    The independent evolution of harmful organisms from one bacterial family – April 21, 2014
    Excerpt: “Before this study, there was uncertainty about what path these species took to become pathogenic: had they split from a shared common pathogenic ancestor? Or had they evolved independently”,,,
    By examining the whole genomes of both the pathogenic and non-pathogenic species, they were able to determine that many of the metabolic functions, lost by the pathogenic species, were ancestral. These functions were probably important for growth in a range of niches, and have been lost rather than gained in specific family lines in the Yersinia family.
    “We commonly think bacteria must gain genes to allow them to become pathogens. However, we now know that the loss of genes and the streamlining of the pathogen’s metabolic capabilities are key features in the evolution of these disease-causing bacteria,”

    Moreover, Dr. Sanford has also made a compelling case, based on empirical evidence, that genetic entropy eventually drives pathogenic viruses into extinction over relatively short time-frames

    Evolution and the Ebola Virus: Pacing a Small Cage – Michael Behe – October 24, 2014
    Excerpt: The high rate of mutation of Ebola is similar to what John Sanford has demonstrated for the H1N1 virus that caused the influenza pandemic after World War I. He makes a compelling case that the accumulating mutations there were degradatory could not be eliminated easily by selection, and eventually caused the virus’s extinction in 2009.

    For the creation was subjected to futility, not willingly, but because of Him who subjected it, in hope that the creation itself also will be set free from its slavery to corruption into the freedom of the glory of the children of God.
