• Modeling the origins of life: New evidence for an 'RNA World'

    ...
    But how did all of this begin? In the origins of
    life, long before cells and proteins and DNA,
    could a similar sort of evolution have taken
    place on a simpler scale? Scientists in the
    1960s, including Salk Fellow Leslie Orgel,
    proposed that life began with the "RNA World,"
    a hypothetical era in which small, stringy RNA
    molecules ruled the early Earth and established
    the dynamics of Darwinian evolution.

    New research at the Salk Institute now provides
    fresh insights on the origins of life, presenting
    compelling evidence supporting the RNA World
    hypothesis. The study, published in Proceedings
    of the National Academy of Sciences (PNAS),
    unveils an RNA enzyme that can make accurate
    copies of other functional RNA strands, while
    also allowing new variants of the molecule to
    emerge over time. These remarkable capabilities
    suggest the earliest forms of evolution may have
    occurred on a molecular scale in RNA.

    The findings also bring scientists one step
    closer to re-creating RNA-based life in the
    laboratory. By modeling these primitive
    environments in the lab, scientists can
    directly test hypotheses about how life may
    have started on Earth, or even other planets.

    RNA-catalyzed evolution of catalytic RNA

    Abstract
    An RNA polymerase ribozyme that was obtained
    by directed evolution can propagate a functional
    RNA through repeated rounds of replication and
    selection, thereby enabling Darwinian evolution.
    Earlier versions of the polymerase did not have
    sufficient copying fidelity to propagate
    functional information, but a new variant with
    improved fidelity can replicate the hammerhead
    ribozyme through reciprocal synthesis of both
    the hammerhead and its complement, with the
    products then being selected for RNA-cleavage
    activity. Two evolutionary lineages were
    carried out in parallel, using either the prior
    low-fidelity or the newer high-fidelity
    polymerase. The former lineage quickly lost
    hammerhead functionality as the population
    diverged toward random sequences, whereas the
    latter evolved new hammerhead variants with
    improved fitness compared to the starting RNA.
    The increase in fitness was attributable to
    specific mutations that improved the
    replicability of the hammerhead,
    counterbalanced by a small decrease in
    hammerhead activity. Deep sequencing analysis
    was used to follow the course of evolution,
    revealing the emergence of a succession of
    variants that progressively diverged from the
    starting hammerhead as fitness increased. This
    study demonstrates the critical importance of
    replication fidelity for maintaining heritable
    information in an RNA-based evolving system,
    such as is thought to have existed during the
    early history of life on Earth. Attempts to
    recreate RNA-based life in the laboratory must
    achieve further improvements in replication
    fidelity to enable the fully autonomous
    Darwinian evolution of RNA enzymes as complex
    as the polymerase itself.

    "Darwinian Evolution," besides making things difficult
    when everyone later claims that they're not "Darwinists,"
    is just plain wrong. Darwin believed that if an animal
    ran a lot, their leg muscles would grow and produce
    "Bigger, running-around-a-lot" Gemmules which would
    flow to the gonads and be passed on the the next
    generation, who would be born with the bigger, running
    around a lot muscles.

    As i pointed out many times, and will point out many
    more times because, let's face it, the last thing
    anyone in this group ever wanted was science but...

    Darwin REJECTED evolution. He didn't believe in it. Oh,
    he did eventually use that word but this is the internet.
    We're all quite accustomed to people misusing terms, and
    Darwin was a pioneer. In fact, later, in the Communist
    world, Stalin and then Mao banned evolution, and in it's
    place promoted Darwin's ideas. Renamed, of course. But
    they were all copying the exact same source material,
    Lamarcksim...

    Darwin was an idiot. And he certainly never invented or
    discovered evolution. Evolution was already quite old
    by the time that Darwin sabotaged science with his
    inability to grasp it. No, sorry, evolution was always
    part of "Common Descent," and if you do the Google
    you'll find sources pushing THAT idea back into the
    thousands of years..

    Darwin's single biggest impact on science -- REAL
    science, as opposed to the British aristocracy
    glorifying itself -- was HOLDING BACK science in
    the English speaking world for 20 years by becoming
    the face of Naturalism and throwing aside Mendel.

    Yes, it took that long -- 20 years -- for some Brit
    with a stick up his ass to pretend that he made
    Mendel's discoveries...

    This is important. It's not a small error. When someone
    spews an oxymoron like "Darwinian Evolution" it's not
    because they're so meticulous in their work. No. It's
    because they are hitting buckets. They're communicating.
    They are invoking things that the layman will recognize
    as familiar. They are, as the saying goes, "Putting
    lipstick on a pig."

    "I said DARWINIAN evolution! That's cus I is edu ma
    kated. I know stuff."

    Again, not a small error. It makes the piece as being
    meant for "The un edu ma kated"... the only people who
    might find "Darwinian" evolution sciency!

    Demand accuracy.

    Don't you think you're worth it?

    Don't you think the promotion of science is worth it?

    Demand accuracy. Don't tolerate being dummed down by
    your efforts to learn and grow. It's not an unreasonable
    request, demanding publications that are accurate.

    Darwin didn't know about genes, but then his book was published before
    Mendel, so you can't really blame him for that. As for rejecting
    evolution, well the last line in 'The Origin of Species' is:

    ", from so simple a beginning endless forms most beautiful and most wonderful have been, and are being, evolved."

    I demand accuracy.

    Mendel worked it all out, Darwin was exposed to it AND

    Omg. I'll repeat it:

    Stalin. Mao.

    I don't know about Mao, but Stalin had no problem with evolution. In
    1959 (100 years after The Origin; 150 years after Darwin's birth) I was
    at the same school as Darwin, many years after him. The Academy of
    Sciences of the USSR sent the school a commemorative medal. (Don't
    bother to tell me that Stalin had died by then: I know.) Interest in
    Darwinism was at low ebb in England in 1959, and the anniversaries
    passed almost unnoticed.

    They banned evolution. They saw is as Capitalist
    propaganda -- justification for everything from racism into
    classism and onto economic exploitation. So they banned
    evolution. And what they put in it's place was Darwin's ideas,
    what Darwin believed it.

    Insofar as there is any sense at all in what you say, you're probably
    confusing Darwin with Mendel.

    Yes, you're right, Darwin was a raging idiot who had no clue
    what he meant, much less what he was talking about. That was
    already established.

    Darwin was an idiot. And he certainly never invented or
    discovered evolution. Evolution was already quite old
    by the time that Darwin sabotaged science with his
    inability to grasp it. No, sorry, evolution was always
    part of "Common Descent," and if you do the Google

    science, as opposed to the British aristocracy
    glorifying itself -- was HOLDING BACK science in
    the English speaking world for 20 years by becoming
    the face of Naturalism and throwing aside Mendel.

    Yes, it took that long -- 20 years -- for some Brit
    with a stick up his ass to pretend that he made
    Mendel's discoveries...

    This is important. It's not a small error. When someone
    spews an oxymoron like "Darwinian Evolution" it's not
    because they're so meticulous in their work. No. It's
    because they are hitting buckets. They're communicating.
    They are invoking things that the layman will recognize
    as familiar. They are, as the saying goes, "Putting
    lipstick on a pig."

    "I said DARWINIAN evolution! That's cus I is edu ma

    your efforts to learn and grow. It's not an unreasonable
    request, demanding publications that are accurate.

    Darwin didn't know about genes, but then his book was published before
    Mendel, so you can't really blame him for that. As for rejecting
    evolution, well the last line in 'The Origin of Species' is:

    ", from so simple a beginning endless forms most beautiful and most
    wonderful have been, and are being, evolved."

    I demand accuracy.


    JTEM has for many years trolled many newsgroups. Whether he is a

    Only "Almost"? You're too kind.

    If all Erik said was just to say it is rubbish, you would have raised

    I wasn't talking about Erik in particular, there were two other replies.

    However, even if he had, that shouldn't stop you
    from posting something more substantial.

    Well I did, but I wasn't going to spend all day on it.

    For example, you could have
    pointed out that just about any mechanism for passing on traits would
    still lead to evolution. The fact that Darwin's speculations about
    that mechanism are wrong doesn't inform that his actual theory of the
    origin of species by means of natural selection remains valid.

    It's not a metaphor.

    It's a misquote, or rather a misattribution.

    Misquote of whom? Darwin uses the phrase in the 1872 edition (it is even
    a chapter title) although he attributes it to Herbert Spencer. Darwin
    says "But the expression often used by Mr. Herbert Spencer, of the
    Survival of the Fittest, is more accurate, and is sometimes equally

    Darwin's original phrase was Natural Selection - an analogy with

    which is genetic drift.)

    find Spencer's Survival of the Fittest more comprehensible. The issue
    perhaps is that fittest has shades of meaning - Survival of the Best
    Adapted would seem to closer to how Darwin understood it. See Selection
    in Relation to Sex.

    I'm not sure what literary classification to place Survival of the
    Fittest in. It's not obviously an analogy like Natural Selection. It's
    not a definition. (Lawyer Daggett's complaint may be that you were

    The phrase "survival of the fittest" has always seemed suspect to
    me. We hear it repeated to justify capitalism. But there isn't any >>>>>> requirement to be 'fit' as far as I can see. There is only a
    requirement (for genes) to survive. For example the camel which
    sits on the calf of its rival and crushes it to death, or the
    chimpanzee which kills and eats the infant offspring of its
    rivals. In what way is it 'fit'? A biologist would define it as
    merely fit to survive, but then the phrase becomes redundant as
    survival of the survivor. And we see the same results in captialism >>>>>> with corporations swallowing up rivals rather than competing with
    them.

    You want to argue against a metaphor by considering it literally.
    It's not a metaphor.

    Darwin's original phrase was Natural Selection - an analogy with
    Artificial Selection. The phenomenon is differential reproductive
    success causally correlated with hereditary traits. (As opposite to
    differential reproductive success not correlated with hereditary
    traits, which is genetic drift.)

    As I understand, Darwin was frustrated that people failed to
    understand the concept of Natural Selection, and hoped that perhaps
    people would find Spencer's Survival of the Fittest more
    comprehensible. The issue perhaps is that fittest has shades of
    meaning - Survival of the Best Adapted would seem to closer to how
    Darwin understood it. See Selection in Relation to Sex.

    I'm not sure what literary classification to place Survival of the
    Fittest in. It's not obviously an analogy like Natural Selection. It's
    not a definition. (Lawyer Daggett's complaint may be that you were
    treating it as a definition.) Perhaps it's a catchphrase or a sound
    bite. One could certainly make a case for it being a metaphor -
    survival of the fittest for persistence of adaptive traits. (Now I
    wonder how contemporaries interpreted the trait - modern understanding
    has been modified by the rhetoric of Creationists and Social
    Tennysonists (often the same people).

    I think it is only an analogy if you take it in the general meaning of
    the word fit, as in fit as a fiddle or fit and healthy, but in the
    biological sense it merely means able to survive, and that is quite
    precise. But when it is used to justify economic policy it is used in
    the more general sense in an attempt to link the two idea of natural
    selection and free market competition. So we are led to believe it will
    lead to lean and efficient, like a cheetah, but it doesn't necessarily.

    The subject of "biological fitness" has a distinguished(?) history, and misconceptions abound.  Here's a reference (with many included
    references) to the subject.  Not an easy read: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2753274/


    Chapter 10 of Dawkin's The Extended Phenotype is entitled "An Agony in
    Five Fits" and discusses the lack of uniformity in concepts of fitness.
    Perhaps it might be more accessible*. (Though, if memory serves me, I
    thought it was the weakest chapter in the book.)

    (Apparently Dawkins was not a great fan of the term.)

    * The Extended Phenotype was written for biologists rather than
    laypeople, but I found it quite readable.
