MINIMAL RULES. "We demonstrate that for a catalytic network to accumulate adaptations it needs to be compartmentalized, the platonic reaction network must have multiple attractors, and some of these attractors must be selectable. The larger the number of attractors, the smaller the chance of convergence." https://lnkd.in/euzMX5X View in LinkedIn

CHEMICAL UNITS OF EVOLUTION. "It should come as no surprise, our finding that independent viable autocatalytic cores embedded in a large molecular network can be considered as units of evolution, since the basic ingredients of differential growth rates and division times among potentially competing entities are fulfilled." https://lnkd.in/euzMX5X View in LinkedIn

COMPARTMENTAL GROWTH. "The viable cores could be considered the units that replicate and, once transmitted to the offspring compartments after the parental compartment splits (reproduces), they give raise to the same periphery; that is; there is a clear matching between a viable core ('genotype') and the periphery ('phenotype')." https://lnkd.in/euzMX5X View in LinkedIn

CHEMICAL INHERITANCE. "Thus, our autocatalytic networks are capable of stably transmitting information across generations." https://lnkd.in/euzMX5X View in LinkedIn

"A CHEMICAL BESTIARY is similar to concepts of in silico evolution. This was an artificial selection experiment." https://lnkd.in/euzMX5X View in LinkedIn

SONG OF DARWIN. "The more I study nature, the more I become impressed […] that the contrivances and beautiful adaptations [acquired through natural selection] transcend in an incomparable degree [those] which the most fertile imagination of the most imaginative man could suggest with unlimited time at his disposal." http://www.sciencedirect.com/science/article/pii/S0960982214003881 View in LinkedIn

FRAGMENT FROM NATURE considers the evolution of the stuff that life is made of, namely carbon, hydrogen, nitrogen, oxygen, phosphorus and sulfur, also called the biogenic elements, the primary elements of life. Where did these elements come from, and how were they made? View in LinkedIn

HITCHHIKER’S LAMENT. “The first ten million years were the " "worst," said Marvin, "and the second ten million years, they were " "the worst too. The third ten million years I didn't enjoy at all. " "After that I went into a bit of a decline." https://en.m.wikiquote.org/wiki/The_Hitchhiker%27s_Guide_to_the_Galaxy View in LinkedIn

EVOLUTION OF STARS. “The idea that stars change as they age and that" "these changes in turn alter their local environment and the chemical" "makeup of their parent galaxy — an idea that has developed only within" "the past fifty years — stands in the same relation to astronomy as the" "Darwinian revolution does to biology. It is a conceptual breakthrough that" "makes possible the modern understanding of the origin, evolution, and " "fate of the universe.” https://lnkd.in/d5GTUVD View in LinkedIn

STUNNING REALIZATION. “All the carbon required for life to exist is synthesized in stars.” (Professor Sir Fred Hoyle, brilliant deceased chair of the Institute of Astronomy at Cambridge University, whose members included Stephen Hawking). https://lnkd.in/d84mun4 View in LinkedIn
