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 ]
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 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 ...
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.
Ecological, evolutionary, developmental biology compares these subgenres of biology. Interaction between organisms and the environment is very important. Climate change intensely alters these interactions and is cause for concern in regard to the overall well-being of our ecological landscape.
Modern evolutionary theory defines fitness not by how long an organism lives, but by how successful it is at reproducing. If an organism lives half as long as others of its species, but has twice as many offspring surviving to adulthood, its genes become more common in the adult population of the next generation.
Professor of biology Jerry Coyne sums up biological evolution succinctly: [3]. Life on Earth evolved gradually beginning with one primitive species – perhaps a self-replicating molecule – that lived more than 3.5 billion years ago; it then branched out over time, throwing off many new and diverse species; and the mechanism for most (but not all) of evolutionary change is natural selection.
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 .
