George Montañez: Specified complexity, design, and surprise
Digging further into George Montañez’s new paper at BIO-Complexity, a lay-friendly version: Specified complexity allows us to measure how surprising random outcomes are, in reference to some probabilistic model. But there are other ways of measuring surprise. In Shannon’s celebrated information theory (Shannon 1948), improbability alone can be used to measure the surprise of observing […]
George Montañez: Using specified complexity to rule out Darwinian explanations
A lay-friendly version of Montanez’s paper at B IO-Complexity translates from the math.
Oxytricha trifallax: A Russian doll set of confounding genetic complexity
The eukaryote smashes and rearranges its genome. Our results show that a great diversity of scrambled gene maps are present in the germline genome of O. trifallax. The presence of such highly nested architectures was a surprise and suggests that layers upon layers of MDS and gene translocations constantly alter the genome, while the detection […]
Upright Biped’s summary on information systems in cell based life
UD participant Upright Biped (of Complexity Cafe U/D: Biosemiosis) has commented recently in the what is knowledge thread, replying to frequent objector CR by summarising key aspects of the role of information systems in observed cell based life. His remarks are well worth headlining: __________________ UB, 195: >>We can start by summarizing the core physical […]
Zap! RNA World gets another brief jolt of life
From ScienceDaily: The spark of life, the authors say, was the creation of RNA polymers: the essential components of nucleotides, delivered by meteorites, reaching sufficient concentrations in pond water and bonding together as water levels fell and rose through cycles of precipitation, evaporation and drainage. The combination of wet and dry conditions was necessary for […]
