SocialismSocialism is a political philosophy and movement encompassing a wide range of economic and social systems which are characterised by social ownership of the means of production, as opposed to private ownership. As a term, it describes the economic, political, and social theories and movements associated with the implementation of such systems. Social ownership can be public, community, collective, cooperative, or employee. While no single definition encapsulates the many types of socialism, social ownership is the one common element, and is considered left-wing.
On the Origin of SpeciesOn the Origin of Species (or, more completely, On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life) is a work of scientific literature by Charles Darwin that is considered to be the foundation of evolutionary biology; it was published on 24 November 1859. Darwin's book introduced the scientific theory that populations evolve over the course of generations through a process of natural selection.
Social democracySocial democracy is a political, social, and economic philosophy within socialism that supports political and economic democracy. As a policy regime, it is described by academics as advocating economic and social interventions to promote social justice within the framework of a liberal-democratic polity and a capitalist-oriented mixed economy. The protocols and norms used to accomplish this involve a commitment to representative and participatory democracy, measures for income redistribution, regulation of the economy in the general interest, and social welfare provisions.
SpeciationSpeciation is the evolutionary process by which populations evolve to become distinct species. The biologist Orator F. Cook coined the term in 1906 for cladogenesis, the splitting of lineages, as opposed to anagenesis, phyletic evolution within lineages. Charles Darwin was the first to describe the role of natural selection in speciation in his 1859 book On the Origin of Species. He also identified sexual selection as a likely mechanism, but found it problematic.
Punctuated equilibriumIn evolutionary biology, punctuated equilibrium (also called punctuated equilibria) is a theory that proposes that once a species appears in the fossil record, the population will become stable, showing little evolutionary change for most of its geological history. This state of little or no morphological change is called stasis. When significant evolutionary change occurs, the theory proposes that it is generally restricted to rare and geologically rapid events of branching speciation called cladogenesis.
ReformismReformism is a political doctrine advocating the reform of an existing system or institution instead of its abolition and replacement via revolution. Within the socialist movement, reformism is the view that gradual changes through existing institutions can eventually lead to fundamental changes in a society's political and economic systems. Reformism as a political tendency and hypothesis of social change grew out of opposition to revolutionary socialism, which contends that revolutionary upheaval is a necessary precondition for the structural changes necessary to transform a capitalist system to a qualitatively different socialist system.
Charles Darwin'Charles Robert Darwin' (ˈdɑrwɪn ; 12 February 1809 – 19 April 1882) was an English naturalist, geologist, and biologist, widely known for his contributions to evolutionary biology. His proposition that all species of life have descended from a common ancestor is now generally accepted and considered a fundamental concept in science. In a joint publication with Alfred Russel Wallace, he introduced his scientific theory that this branching pattern of evolution resulted from a process he called natural selection, in which the struggle for existence has a similar effect to the artificial selection involved in selective breeding.
ExtinctionExtinction is the termination of a taxon by the death of its last member. A taxon may become functionally extinct before the death of its last member if it loses the capacity to reproduce and recover. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence.
Fabian SocietyThe Fabian Society is a British socialist organisation whose purpose is to advance the principles of social democracy and democratic socialism via gradualist and reformist effort in democracies, rather than by revolutionary overthrow. The Fabian Society was also historically related to radicalism, a left-wing liberal tradition. As one of the founding organisations of the Labour Representation Committee in 1900, and as an important influence upon the Labour Party which grew from it, the Fabian Society has had a powerful influence on British politics.
Democratic socialismDemocratic socialism is a left-wing political philosophy that supports political democracy and some form of a socially owned economy, with a particular emphasis on economic democracy, workplace democracy, and workers' self-management within a market socialist economy or an alternative form of a decentralised planned socialist economy. Democratic socialists argue that capitalism is inherently incompatible with the values of freedom, equality, and solidarity and that these ideals can only be achieved through the realisation of a socialist society.
