Bacterial Evolution
Billions of Years
Quadrillions of Divisions
Nary a leg,eye,brain nor mouth.
You would think they should have evolved the most.
Yet they defy the theory of “Evolution” by staying the same.

    Bacteria are single celled organisms so they can’t have mouths or brains etc. However they have evolved just as much as the eukaryotic cells in your body have. Differently of course but evolved none the less.

    Funny design though. It’s not often you see one of these ‘evolution’ tees that actually offer something new.

  • Bacteria have a new generation every 20 minutes, whiles humans are about every 20 years.
    A year of bacterial evolution would be proportionate to a half million years of human evolution.
    The bacteria that existed 2000 years ago have had a the same relative amount of generations as humans would have had in a billion years. Given that these one cell creatures have not evolved from their one cell domain, does not give much credence to evolution. At least in terms of one species changing into another.
    BTW thanks for the design compliment.

    Sorry to correct you there, Paul, but bacteria species far outnumber all other forms of life. The number of bacterial species is so large that they’re impossible to count with today’s technology but the current estimate is between 10 million and a billion. Compare that to the estimated 10 to 30 million animal species (including isnsects, mammals, birds, reptiles coral etc) and bacteria actually make up the majority.

    So if you’re measuring a kingdom’s evolutionary progress by it’s ability to differentiate into different species then bacteria are superstars for at least the reasons you mentioned.

    If the fact that bacteria are still single celled organisms is still bothering you then let consider the following:
    1. Bacteria are doing very well for themselves as just single celled creatures (they make up the majority of life on the planet, remember).
    2. Diversifying into multi-cellularity would be very tough considering the competition.
    3. And this is a big one: they have already evolved to have eyes, mouths, arms, legs, wings, tails, gills, teeth etc because the animal kingdom evolved FROM bacteria.

    And before you ask “why are there still bacteria then if they evolved into us?” it’s because there is still a ecological niche for them. See point one for reasons for some of the species that diverged billions of years ago to stay as microscopic super adaptive organisms.

    I hope this helps.

  • I find it interesting that in the terms of supposed Human Evolution that mankind has made magnificent strides in the past 500,000 years.
    This amounts to 1 year of bacterial generations. I don’t believe the evolutionists can have it both ways.
    Scientists should be able with bacteria show major gains of evolution in a Petrie dish, as of yet, I haven’t seen anyone try or succeed at that.

    What kind of human evolution are you thinking of that’s occurred in the last 500,000?

  • The Wiki link above, shows how humans have had 2 species changes in the past 500,000 years or ~25,000 generations. It also shows that we have differentiated from chimps 5 Million years ago, about 250,000 generations. It has been said that we and chimps have 97% of the same DNA.
    We have about 26,000 genes and 3 billion base pairs in our DNA. 3% of 3 Billion is 90 MiIllion changes in our DNA in 250,000 generations, or 360 successful DNA changes per generation. Then each successful change has to be compounded upon the other to eventually form successful genes made up of many correctly sequenced base pairs. The math doesn’t add up.

    In regards to “the math”; the “360 successful DNA changes per generation” don’t have to compound within each generation to amount to species divergence. The mutations increase the amount of genetic diversity in the gene pool that culminate in increased adaptability. When a population is separated (most commonly geographically) for long enough and experiences different environmental pressures, adaptations in one or both of the separate populations lead to genetic differentiation that in some cases leads to the ‘creation’ of a new species ie. the genetic differentiation is so pronounced that the two populations can no longer interbreed.

    Sorry for that exceedingly long sentence.

    Back to your original claim that bacteria should have ‘evolved’ a great deal more in the same period because of their comparatively shorter generations then I can say with confidence that there has probably been a great many more than just two new species (or in case of bacteria; ‘strains’) formed in the last 500,000 years.

    Thanks for the engaging discussion. I’ll leave to last word to you. :)

  • Thanks Mike this has been engaging.
    Many species have a large adaptive ability and variety built right into its gene set.
    We can see this in the canine population. Creatures can an do adapt.
    However, evolution requires that adaption comes from mutation or adding and removing genes that did not exist previously. The odds of that happening randomly are beyond reason. I have yet to see any scientific findings that have shown an organism that can create its own genes that it would need to evolve. There’s the rub. We see changes in populations, but science can not give answers, only speculations. The problem is the speculations don’t match the numbers.
