EVOLUTION OF INFORMATION. “How did information first gain causal purchase over certain complex systems that we now call living organisms?” http://rsif.royalsocietypublishing.org/content/10/79/20120869 View in LinkedIn

TRANSITION OF STATES. “We therefore identify the transition from non-life to life with a fundamental shift in the causal structure of the system, specifically a transition to a state in which algorithmic information gains direct, context-dependent, causal efficacy over matter.” http://rsif.royalsocietypublishing.org/content/10/79/20120869 View in LinkedIn

FRAGMENT FROM NATURE continues from last weekend on the theme of biological information. Most scientists today see this information as key to all life processes. How did biological information evolve? Did the transition from non-life to life come first? These are some of the interesting problems to figure out. View in LinkedIn

FRESH GENES. "Greater niche differentiation between progenitor and neopolyploid increases the proximity and opportunity to mate with other neopolyploids, a key factor in polyploid establishment." https://lnkd.in/eee56_B View in LinkedIn

TRIVIAL VERSUS NON-TRIVIAL REPLICATORS. “Although von Neumann automata are self-replicators, their mode of replication is non-trivial in a fundamental, logical sense, and should be distinguished from trivial replicators such as crystals, viruses, computer viruses, non-enzymatic template replicators, lipid composomes and Penrose blocks.” http://rsif.royalsocietypublishing.org/content/10/79/20120869 View in LinkedIn

A BETTER LIFE. "An evolutionary advantage may accrue to allopolyploids from higher rates of population establishment and persistence. This may occur because genome doubling, especially when two divergent genomes are present, provides an immediate vehicle for transcending parental niches." https://lnkd.in/eee56_B View in LinkedIn

HARDWARE AND SOFTWARE. “An explanation of life's origin is fundamentally incomplete in the absence of an account of how the unique causal role played by information in living systems first emerged. In other words, we need to explain the origin of both the hardware and software aspects of life, or the job is only half finished.” http://rsif.royalsocietypublishing.org/content/10/79/20120869 View in LinkedIn

FITNESS ADVANTAGE. "Although we found that autopolyploids and allopolyploids occurred near parity in nature, allopolyploids likely have a significant evolutionary advantage. Autopolyploid plants were probably produced in higher numbers than allopolyploid plants throughout contemporary species’ ranges and over the course of deep time. The differential might have been five-fold or 20-fold." https://lnkd.in/eee56_B View in LinkedIn

ALLOPOLYPLOID. "Definition of allopolyploid: a polyploid individual or strain having a chromosome set composed of two or more chromosome sets derived more or less complete from different species." https://lnkd.in/e-MaEau View in LinkedIn
