Evolution, Selfishness and Cooperation
It is argued that replicators evolving through natural selection on the basis of fitness are intrinsically selfish. Though the synergy resulting from cooperation is generally advantageous, selfish or subsystem optimization precludes the reaching of a globally optimal cooperative arrangement. This predicament is exemplified by the "Prisoner's dilemma". Different proposals to explain the evolutio...
متن کاملEvolution of Cooperation: Does Selfishness Restraint Lie within?
Traditional models of how cooperative strategies succeed in evolution have largely focused on social interactions among individuals and selection acting at kin and group levels. A recent study at the genetic level suggests that cooperation may also be promoted by the evolution of gene-trait relationships that limit the range of possible cheating mechanisms that can evolve.
متن کاملEvolution and selfishness
(This paper is not a paper; in other words, not even a draft. It is a compilation of different themes I have been thinking of during the last months. Being a compilation, the different "chapters" are not coherent. When I made changes in some chapters, these changes would have entailed that I change the content in other chapters too. But I have not had the time to do so. There are therefore all ...
متن کاملSelfishness, Cooperation and Topology Dynamics in Networks
We study the dynamics of a network of agents (players) under two models settings. In the first model, players (agents) extend heterogeneous cooperation levels to their partners and in the second, perfectly rational and selfish agents engage in an iterated Snowdrift Game and the evolution of the system suggests that cooperation emerges and prevails even when no external rules or norms for punish...
متن کاملMolecular Evolution of piggyBac Superfamily: From Selfishness to Domestication
The piggyBac transposable element was originally isolated from the cabbage looper moth, Trichoplusia ni, in the 1980s. Despite its early discovery and specificity compared to the other Class II elements, the diversity and evolution of this superfamily have been only partially analyzed. Two main types of elements can be distinguished: the piggyBac-like elements (PBLE) with terminal inverted repe...
