Evolution by Natural Selection
The first published expression of the theory of evolution by natural selection was printed July 1, 1858, in the Journal of the Linnaean Society of London in the form of two essays: one by Charles Darwin and one by Alfred Russel Wallace. These two essays, along with Darwin's preliminary Sketch of 1842 and his Essay of 1844 (neither of which were published until 1909), and a foreword by Sir Gavin...
متن کاملNatural selection in chemical evolution.
We propose that chemical evolution can take place by natural selection if a geophysical process is capable of heterotrophic formation of liposomes that grow at some base rate, divide by external agitation, and are subject to stochastic chemical avalanches, in the absence of nucleotides or any monomers capable of modular heredity. We model this process using a simple hill-climbing algorithm, and...
متن کاملReply to Lee: Spatial sorting, assortative mating, and natural selection
Lee (1) suggests that spatial sorting will be important only under limited circumstances, that it may often affect traits also subject to natural selection, and that it will enhance the effectiveness of selection by increasing phenotypic variance via positive assortative mating. These points build on the arguments advanced in our original paper, and we broadly agree with him. First, Lee (1) sug...
متن کاملNatural Selection and Thermodynamics of Biological Evolution
The author of this article proposes that the representation of Charles Darwin and Alfred Wallace’s theory on “variation and selection” in the living world is a reflection of the action of hierarchical thermodynamics. Hierarchical thermodynamics is based on the law of temporal hierarchies and on the principle of substance stability. This principle enables the transmission of thermodynamic inform...
متن کاملNatural Selection and Cultural Selection in the Evolution of Communication
Computational simulations of natural selection for communicative success show that natural selection alone is capable of evolving optimal communication systems. Simulations of the interactions between natural selection and learning show that the biases of learners, when placed in the framework of iterated cultural transmission of communication systems, result in cultural selection of communicat...
