EvolutionIn biology, evolution is the change in heritable characteristics of biological populations over successive generations. Evolution occurs when evolutionary processes such as natural selection (including sexual selection) and genetic drift act on genetic variation, resulting in certain characteristics becoming more or less common within a population over successive generations. The process of evolution has given rise to biodiversity at every level of biological organisation.
Group decision-makingGroup decision-making (also known as collaborative decision-making or collective decision-making) is a situation faced when individuals collectively make a choice from the alternatives before them. The decision is then no longer attributable to any single individual who is a member of the group. This is because all the individuals and social group processes such as social influence contribute to the outcome. The decisions made by groups are often different from those made by individuals.
Generalized Riemann hypothesisThe Riemann hypothesis is one of the most important conjectures in mathematics. It is a statement about the zeros of the Riemann zeta function. Various geometrical and arithmetical objects can be described by so-called global L-functions, which are formally similar to the Riemann zeta-function. One can then ask the same question about the zeros of these L-functions, yielding various generalizations of the Riemann hypothesis. Many mathematicians believe these generalizations of the Riemann hypothesis to be true.
Animal Behaviour (journal)Animal Behaviour is a double-blind peer-reviewed scientific journal established in 1953 as The British Journal of Animal Behaviour, before obtaining its current title in 1958. It is published monthly by Elsevier for the Association for the Study of Animal Behaviour in collaboration with the Animal Behavior Society. It covers all aspects of ethology, including behavioural ecology, evolution of behaviour, sociobiology, ethology, behavioural physiology, population biology, and navigation and migration.
Estate agentAn estate agent is a person or business that arranges the selling, renting, or managing of properties and other buildings. An agent that specialises in renting is often called a letting or management agent. Estate agents are mainly engaged in the marketing of property available for sale, and a solicitor or licensed conveyancer is used to prepare the legal documents. In Scotland, however, many solicitors also act as estate agents, a practice that is rare in England and Wales.
Direct actionDirect action is a term for economic and political behavior in which participants use agency—for example economic or physical power—to achieve their goals. The aim of direct action is to either obstruct a certain practices (such as a government's laws or actions) or to solve perceived problems (such as social inequality). Direct action may include activities, often nonviolent but possibly violent, targeting people, groups, institutions, actions, or property that its participants deem offensive.
First-past-the-post votingFirst-past-the-post voting (FPTP or FPP) is an electoral system wherein voters cast a vote for a single candidate, and the candidate with the most votes wins the election. Analogous systems for multi-winner contests are known as plurality block voting or "block voting" systems; both FPTP and block voting are "plurality" systems in that the winner needs only a plurality (the greatest number) of the votes and not an absolute majority (greater than half).
Timeline of the evolutionary history of lifeThe timeline of the evolutionary history of life represents the current scientific theory outlining the major events during the development of life on planet Earth. Dates in this article are consensus estimates based on scientific evidence, mainly fossils. In biology, evolution is any change across successive generations in the heritable characteristics of biological populations. Evolutionary processes give rise to diversity at every level of biological organization, from kingdoms to species, and individual organisms and molecules, such as DNA and proteins.
