ENHANCED GENE HUNTING. "Neutrality enables the organism to better sample the pool of available mutations by being able to discover beneficial mutants without constantly being penalized by the already high frequency of deleterious mutations. Beneficial mutations are hard to come by in a single try, but can become more likely if interspersed by a series of neutral ones. In essence, neutral mutations allow organisms to buy more time in their quest for discovering survivability-enhancing traits." https://lnkd.in/dGC6A7c View in LinkedIn

MOSTLY HARMLESS. "It is clear that the emergence of an evolvable threat could be potentially disastrous. On the other hand, it is entirely possible that evolution will in most cases lead to harmless forms of a threat, as is often observed in biology." Cold comfort for the small percentage of disastrous threats. https://lnkd.in/dGC6A7c View in LinkedIn

PREREQUISITES OF COMPLEXITY. "Finally, the number of variants (mutants) with non-zero fitness (sometimes called the neutral fraction of mutants) should be sizable. It has been shown that ideally between 10%-40% of all mutations experienced by a population need to be neutral to ensure evolvability. (Note that the fraction of mutants of biological proteins is also in that range.)" https://lnkd.in/dGC6A7c View in LinkedIn

PREREQUISITES OF COMPLEXITY IN ARTIFICIAL LIFE. "First and foremost are of course the three conditions for Darwinian evolution themselves: replication, variation and selection. Of those, replication and selection are naturally present, and we argued above that variation can occur via a variety of mechanisms. However, in order for sufficient variation to be present so that selection can act efficiently, population sizes should be large." https://lnkd.in/dGC6A7c View in LinkedIn

"COMPLEX FUNCTIONALITY can evolve from much simpler functions in Artificial Life platforms, over the course of a few days, and complex adaptations have been seen to emerge after tens to tens of thousands of generations, easily within range of weeks of malware evolution." Aeons of evolutionary time which are necessary in biological systems are not required in digital ecosystems. https://lnkd.in/dGC6A7c 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." https://lnkd.in/eykUy37 View in LinkedIn

FRAGMENT FROM NATURE deals with the extraordinary asymmetry issues of flatfish. These are the most asymmetric vertebrates that have ever lived. This lifestyle imposes enormous developmental challenges on their bodies, because they arose from symmetrical vertically oriented fishes and had to torque their bodies to an asymmetric horizontal venue, by moving eyes and organs in their early adulthood. Such Herculean efforts stand out, at the very least, as somewhat bizarre. View in LinkedIn
