Ecological-evolutionary theory (EET) is a sociological theory of sociocultural evolution that attempts to explain the origin and changes of society and culture. [ 1 ] [ 2 ] Key elements focus on the importance of natural environment and technological change . [ 3 ]
In subsequent publications (Power and Privilege, 1966; [14] Human Societies, 1970; [15] and Ecological-Evolutionary Theory, 2006 [16]), Lenski built on the foundations of evolutionary theory laid in the 18th century by A.R.J. Turgot, Adam Ferguson, John Millar, and Thomas Malthus, and in the 19th and 20th centuries by Charles Darwin, Lewis ...
The main subfields of evolutionary ecology are life history evolution, sociobiology (the evolution of social behavior), the evolution of interspecific interactions (e.g. cooperation, predator–prey interactions, parasitism, mutualism) and the evolution of biodiversity and of ecological communities. Evolutionary ecology mostly considers two ...
In r/K selection theory, selective pressures are hypothesised to drive evolution in one of two generalized directions: r - or K-selection. [2] These terms, r and K, are drawn from standard ecological formula as illustrated in the simplified Verhulst model of population dynamics: [9]
Natural selection is the differential survival and reproduction of individuals due to differences in phenotype.It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations.
Darwin's theory of evolution is based on key facts and the inferences drawn from them, which biologist Ernst Mayr summarised as follows: [6] Every species is fertile enough that if all offspring survived to reproduce, the population would grow (fact). Despite periodic fluctuations, populations remain roughly the same size (fact).
Ecological evolutionary developmental biology [c] integrates research from developmental biology and ecology to examine their relationship with evolutionary theory. [78] Researchers study concepts and mechanisms such as developmental plasticity, epigenetic inheritance, genetic assimilation, niche construction and symbiosis. [79] [80]
Human behavioral ecology (HBE) or human evolutionary ecology applies the principles of evolutionary theory and optimization to the study of human behavioral and cultural diversity. HBE examines the adaptive design of traits , behaviors , and life histories of humans in an ecological context.
