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 ...
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.
Population ecology is a sub-field of ecology that deals with the dynamics of species populations and how these populations interact with the environment. [15] It is the study of how the population sizes of species living together in groups change over time and space, and was one of the first aspects of ecology to be studied and modelled mathematically.
Evolutionary biology is the subfield of biology that studies the evolutionary processes (natural selection, common descent, speciation) that produced the diversity of life on Earth. It is also defined as the study of the history of life forms on Earth. Evolution holds that all species are related and gradually change over generations. [1]
Punctuated equilibrium is a refinement to evolutionary theory. It describes patterns of descent taking place in "fits and starts" separated by long periods of stability. Eldredge went on to develop a hierarchical vision of evolutionary and ecological systems. Around this time, he became focused on the rapid destruction of many of the world's ...
Ecological genetics is the study of genetics in natural populations. It combines ecology, evolution, and genetics to understand the processes behind adaptation. [ 1 ] It is virtually synonymous with the field of molecular ecology .
