Elizabeth Liddle- Still Pathetically Overselling AVIDA

Elizabeth Liddle is either very ignorant or very dishonest. She still insists that AVIDA is a good simulation of darwinian/ neo-darwinian evolution. See for yourself. However that claim has been soundly refuted in peer-review:

The effects of low-impact mutations in digital organisms

Chase W. Nelson and John C. Sanford

Theoretical Biology and Medical Modelling, 2011, 8:9 | doi:10.1186/1742-4682-8-9


Background: Avida is a computer program that performs evolution experiments with digital organisms. Previous work has used the program to study the evolutionary origin of complex features, namely logic operations, but has consistently used extremely large mutational fitness effects. The present study uses Avida to better understand the role of low-impact mutations in evolution.


When mutational fitness effects were approximately 0.075 or less, no new logic operations evolved, and those that had previously evolved were lost. When fitness effects were approximately 0.2, only half of the operations evolved, reflecting a threshold for selection breakdown. In contrast, when Avida's default fitness effects were used, all operations routinely evolved to high frequencies and fitness increased by an average of 20 million in only 10,000 generations.


Avidian organisms evolve new logic operations only when mutations producing them are assigned high-impact fitness effects. Furthermore, purifying selection cannot protect operations with low-impact benefits from mutational deterioration. These results suggest that selection breaks down for low-impact mutations below a certain fitness effect, the selection threshold. Experiments using biologically relevant parameter settings show the tendency for increasing genetic load to lead to loss of biological functionality. An understanding of such genetic deterioration is relevant to human disease, and may be applicable to the control of pathogens by use of lethal mutagenesis.

Elizabeth Liddle, proud to be a dishonest ignoramus.

    I'll just delete your sock at TSZ, dipshit.

    LoL! You sure as hell can't actually address any arguments...

    Your Lenski choke was hilarious, Chubs. And you're so easy to spot, because you're simple.

    All you do is choke, cupcake. You are too stupid to actually make a case.

    Hughes, you are a fucking idiot. Population studies kills your speculation not only as to how living systems came to being, but how organismal forms allegedly "transformed" from one to another. The Lenski experiments just proves that you fool.

    Why dont you do something productive and demonstrate something that will actually quantitatively support your conjecture. Asswipe.

    Bprag: "Asswipe."

    Don't lower yourself to Joe's pathetic level. The few discussions that we have had prove that.

    LoL! I respond on the level of comments and people I am responding to. The many discussions that I have had with people like William Spearshake prove that.

    And yes bpragmatic, the "Asswipe" ending was inappropriate given the " you are a fucking idiot" opening. What the fuck is that starting off Henry Rollins and ending with Carly Simon, fuckshit?

    Joe, William and Hughes,

    The name calling on my part was not necessary and could have detracted from the message.

    Sorry about that.
