New Findings Confirm Darwin's Theory — Evolution Not Random

ScienceDaily is reporting a team of biologists has demonstrated that evolution is a deterministic process, rather than a random selection as some competing theories suggested. "When the researchers measured changes in 40 defined characteristics of the nematodes' sexual organs (including cell division patterns and the formation of specific cells), they found that most were uniform in direction, with the main mechanism for the development favoring a natural selection of successful traits, the researchers said."

  1. Wait... what's different here? by eepok · · Score: 4, Informative

    Hmm... I don't understand...

    From what I picked up in bio, it was known to work as such:

    Assume Mutation
    (1) If mutation not hindrance, animal likely to live and likely makes babies.
    (2) If mutation is boon, animal more likely to live and more likely makes babies.
    (3) If mutation is hindrance, animal less likely to live and less likely to make babies

    From there, you consider whether or not the mutation is recessive/dominant which determines if the babies get the mutation (then referred to as a trait).

    Repeat many many times and you get a separation of a special line.

    The proper combination of factors being: mutation = beneficial, mutation dominant, mutated animals screw like proverbial rabbits.

    How is this different from the new findings?

      So there seems to be some sort of mechanism that selects beneficial mutations BEFORE procreation or death kicks in
      You never see stuff like people with 2 alleles for sickle cell disease, because they don't make it to birth. Likewise, very bad mutations are selected against at a very early stage. However, mutations are random, there's no way for a cell to control where some cromosome will change.

    The theory of evolution includes the theory of the selection of advantageous traits, plus methods for the acquisition of new traits, like mutation.

    You are correct in describing facts and theories, but "evolution" can refer to both. This article explains it well I think - Evolution is a Fact and a Theory.

    Creationism and Evolution are not mutually exclusive.

    Yes they are, at least for the standard dictionary definition of creationism:

    creationism:
    1. the doctrine that matter and all things were created, substantially as they now exist, by an omnipotent Creator, and not gradually evolved or developed.
    2. the doctrine that the true story of the creation of the universe is as it is recounted in the Bible, esp. in the first chapter of Genesis.

    Keep in mind, "Creationism" != "Religious faith". There are plenty of people who believe in God and who accept the scientific theory of evolution. But they are not creationists.

    If you think that science deals in facts, you're mistaken. Science is more a process of coming up with explanations for the observations that we have. For example, we see something, we come up with a theory and then set out to "prove" the theory correct. Unfortunately, we find historically, that the scientific proof of things is almost always flawed, as it was with newtonian physics, but is frequently good enough to get by. There is a fundamental misunderstanding here. Science never proves that a theory is "correct" -- theories never become facts -- science instead proves that a theory has useful predictive power. Newton's laws of motion remain "proven" on this basis: the engineering calculations needed to put a man on the moon, for example, were done with deliberate disregard for relativity, for Newton's laws had just as much useful predictive power after Einstein as before.

    A hypothesis doesn't get called a theory until it has demonstrated substantial predictive power, and so is almost never found to be "incorrect" later. Instead conditions are discovered under which the old theory doesn't make useful predictions, and the new theory is "more general", or accurate to more decimal places, etc.

    Just to be clear, so we don't assume any misconceptions here about Einstein and religion:

    I believe in Spinoza's God, Who reveals Himself in the lawful harmony of the world, not in a God Who concerns Himself with the fate and the doings of mankind. -- Einstein

    It was, of course, a lie what you read about my religious convictions, a lie which is being systematically repeated. I do not believe in a personal God and I have never denied this but have expressed it clearly. If something is in me which can be called religious then it is the unbounded admiration for the structure of the world so far as our science can reveal it. -- Einstein

    ID is about HOW Evolution Occurs. It occurs Intelligently. ID says Evolution's theory that it is entirely nature's luck is incorrect. No, "Intelligent Design" is a way of claiming the development of the species is/was directed by God without invoking the 'G' word. It still ascribes the development to an external intelligence which designed the system from scratch. Organisms self-selecting beneficial genes is not what they're talking about when they say "Intelligent Design".

    I don't know why you posted AC, but I couldn't accept your Albert Einstein assertion on faith... even if you had signed your post.

    But the sources for relevant Wikipedia articles are credible primary sources. (Brian, Dennis (1996), Einstein: A Life, New York: John Wiley & Sons, p. 127, ISBN 0-471-11459-6) To save you some time, I've added some line breaks but retained the context.

    In 1929, Boston's Cardinal O'Connell branded Einstein's theory of relativity as "befogged speculation producing universal doubt about God and His Creation," and as implying "the ghastly apparition of atheism." In alarm, New York's Rabbi Herbert S. Goldstein asked Einstein by telegram: "Do you believe in God? Stop. Answer paid 50 words." In his response, for which Einstein needed but twenty-five (German) words, he stated his beliefs succinctly:

    "I believe in Spinoza's God, Who reveals Himself in the lawful harmony of the world, not in a God Who concerns Himself with the fate and the doings of mankind."

    The rabbi cited this as evidence that Einstein was not an atheist, and further declared that "Einstein's theory, if carried to its logical conclusion, would bring to mankind a scientific formula for monotheism." Einstein wisely remained silent on that point.
    Now for the second quote:

    "It was, of course, a lie what you read about my religious convictions, a lie which is being systematically repeated. I do not believe in a personal God and I have never denied this but have expressed it clearly. If something is in me which can be called religious then it is the unbounded admiration for the structure of the world so far as our science can reveal it."

  10. What the article is REALLY about by hung_himself · · Score: 3, Informative

    Wow, this is a triple convergence of a bad and confusing title, summary and article (which is a summary of the actual journal article) which is unusual even for slashdot.

    This really isn't about Darwinian evolution which involves random mutations and selection of the favorable ones. However, there are some characteristics which are neither advantageous or disadvantageous. There is a debate about how many characteristics are "neutral". For example, did large noses appear because they are advantageous (for warming air perhaps) or because they just worked out that way by chance. So the original paper asked this question about worm vulvas and found that nearly all the characteristics that they looked at did NOT arrive by chance but were selected for (i.e. were advantageous in some way).

    It is important to note both possible results would be consistent with Darwinian evolution. The only questions being addressed are the mechanism (does evolution go through mostly neutral phenotypes before a favorable phenotype is selected) and the extent that characteristics are neutral. For worm vulvas, it appears that the vulvas that form are biased towards the most favorable ones.
