A very different kind of Darwinian demon emerged in 2001 with the publication of a paper by Olof Leimar [2]. This one resembles Maxwell’s demon in that it creates nonrandom fitness-enhancing mutations. Normally, mutations are random, and almost all of them are fitness-reducing. Of course,...
图1其实已经把逻辑展示地很清楚了。第一,每个物种都要增长;第二,每个种群都要受外界调控;第三,不同物种本身有差异;第四,因此造成不同物种受调控后增长率不一样,才冒出了 「适合度(fitness)」 这个概念;第五,因此,物竞天择,适者生存;第六,但现实中往往有多个调控因子,此时往往物种能共存,为啥呢?第七,因为...
Explain how Evolution and Natural Selection are different and give an example of natural selection. Can genetic drift increase mean fitness? Explain what the mechanisms of evolution are: 1.) natural selection 2.) non-random mating 3.) mutation 4.) genetic drift 5.) and migration (gene flow)...
as what Darwinians call "fitness signals" -- that is to say, displays that are performances like the peacock's tail, except that, unlike hair and feathers, the hand axes are consciously cleverly crafted. Competently made hand axes indicated desirable personal qualities -- intelligen...
senile substrates of consciousness i.e. archaicHomo sapiens. Our posthuman descendants are more likely to create fellow "smart angels" instead. The triumph of the Reproductive Revolution will have reshaped the post-Darwinian fitness landscape beyond all recognition. Hence my (tentative) prediction that...
The more interesting implications of such an evolutionary philosophy appear to have gotten lost somewhere in the shuffle, however; the same individuals seem equally prone to insist that neo-Darwinian theory must be applied via models in which cultural transmission and evolutionary fitness are treated ...
Evolution, like reinforcement learning, necessarily channels all information about the environment through a one-dimensional bottleneck. It is this scalar-valued function, the fitness function, that must contain all task-related information if the architecture itself is meant to be of general purpose. ...
摘要: Classifier systems (Holland, 1986) have a distinct Darwinian flavor, and in this respect contrast sharply with most other learning systems. In this paper we bring out various aspects of the contrast, and provide an example of classifier system learning which illustrates its quasi-Darwinian ...
Synthetic gene drives can now be designed to "sculpt" evolution. Researchers can take a gene that has a fitness-cost for the individual, for example male sterility, and move ("drive") it through a population in defiance of the usual constraints of Mendelian inheritance. Gene drives achieve ...
