The results of this study suggest that the mere presence of another person in a social situation can inhibit an individual; however, although the individual in charge of completing the experimental task was socially inhibited by the presence of another person in the laboratory, there were no significant links between their social inhibition ...
Another example of allelopathy is seen in Leucaena leucocephala, known as the miracle tree. This plant contains toxic amino acids that inhibit other plants’ growth but not its own species growth. Different crops react differently to these allelochemicals, so wheat yield decreases, while rice increases in the presence of L. leucocephala .
Sociobiology investigates social behaviors such as mating patterns, territorial fights, pack hunting, and the hive society of social insects. It argues that just as selection pressure led to animals evolving useful ways of interacting with the natural environment , so also it led to the genetic evolution of advantageous social behavior.
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]
Also called functionalism. The Darwinian view that many or most physiological and behavioral traits of organisms are adaptations that have evolved for specific functions or for specific reasons (as opposed to being byproducts of the evolution of other traits, consequences of biological constraints, or the result of random variation). adaptive radiation The simultaneous or near-simultaneous ...
Permissive society, a liberalization of social norms in a society. Permissive software license, a free-software license. Permissive cell or permissive host, a cell which allows a virus to circumvent its defenses and replicate. Permissive mood, a grammatical mood found in some languages. Permissive, a 1970 British exploitation drama film.
Epigenetic mechanisms. In biology, epigenetics is the study of heritable traits, or a stable change of cell function, that happen without changes to the DNA sequence. [1] The Greek prefix epi-(ἐπι-"over, outside of, around") in epigenetics implies features that are "on top of" or "in addition to" the traditional (DNA sequence based) genetic mechanism of inheritance.

Whereas sociocultural development traces processes that tend to increase the complexity of a society or culture, sociocultural evolution also considers process that can lead to decreases in complexity (degeneration) or that can produce variation or proliferation without any seemingly significant changes in complexity (cladogenesis).
