Kevin R. McCarthy Blows Another Gasket and Has to Censor Science!
Yup good ole scientopia guest blog- CORRECTION KEVIN WAS DOING ALL THE CENSORING- needs to censor comments that demonstrate their guest bloggers are full of shit.
Case in point- Kevin R. McCarthy thinks that digital organisms fit the requirements of being alive (they don't) and he points to Avida, of all things, to support his claim.
1- Avida "organisms" are far too simple to be considered anything like a biological organism
2- Avida organisms "evolve" via unreasonable parameters:
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.
Yet when I posted this kevin had it deleted- TWICE.
As if I needed more evidence that Kevin R. McCarthy is a low-life, lying loser.
Guess what Kevin? If our confrontation does go to trial I will have a full archive to call on for evidence against you. Thanks...
I just put it here- that seems to be the relevant thread. We will see how long it stays....
