A developmental model of the evolution of the mind, culture, and society was the result, paralleling the evolution of the human species: [23] "Modern savages [sic] became, in effect, living fossils left behind by the march of progress, relics of the Paleolithic still lingering on into the present."
Charismatic species are often used as flagship species in conservation programs, as they are supposed to affect people's feelings more. [2] However, being charismatic does not protect species against extinction; all of the 10 most charismatic species are currently endangered, and only the giant panda shows a demographic growth from an extremely small population.
Cultural evolution is an evolutionary theory of social change. It follows from the definition of culture as "information capable of affecting individuals' behavior that they acquire from other members of their species through teaching, imitation and other forms of social transmission". [1] Cultural evolution is the change of this information ...
The theory of evolution by natural selection has also been adopted as a foundation for various ethical and social systems, such as social Darwinism, an idea that preceded the publication of The Origin of Species, popular in the 19th century, which holds that "the survival of the fittest" (a phrase coined in 1851 by Herbert Spencer, [1] 8 years before Darwin published his theory of evolution ...
Over the following 70 or 80 million years the rate of evolution accelerated by an order of magnitude. [18] Normally rates of evolution are measured by the extinction and origination rate of species, but here we can say that by the end of the Cambrian every phylum, or almost every phylum, existed. The diversity of life began to resemble that of ...

Cooperation among ants is vital, because a solitary ant has an improbable chance of long-term survival and reproduction. However, as part of a group, colonies can thrive for decades. As a consequence, ants are one of the most successful families of species on the planet, accounting for a biomass that rivals that of the human species. [1] [2]
Richard Lenski's classic E. coli long-term evolution experiment is an example of adaptation in a competitive environment, ("improvement in fitness" during "survival of the fittest"). [65] The probability of a beneficial mutation occurring on some member of the lineage to give improved fitness is slowed by the competition.
