Edgar Henry Schein (March 5, 1928 – January 26, 2023) [1] was a Swiss-born American business theorist and psychologist who was professor at the MIT Sloan School of Management.
Dual inheritance theory (DIT), also known as gene–culture coevolution or biocultural evolution, [1] was developed in the 1960s through early 1980s to explain how human behavior is a product of two different and interacting evolutionary processes: genetic evolution and cultural evolution.
Researchers have developed models for understanding an organization's culture or developed typologies of organizational culture. Edgar Schein developed a model for understanding organizational culture. He identified three levels of organizational culture: (a) artifacts and behaviors, (b) espoused values, and (c) shared basic assumptions.
The notion that organizations have culture that can be identified, categorized, and managed was first introduced by Roger Harrison in 1972 (Cartwright & Cooper, 1992, p. 63). While Schein certainly was influential in spreading the word, he cannot be credited with inventing the term. Cartwright, S., & Cooper, G. L. (1992).
Schein claimed that culture is the most difficult organizational attribute to change, outlasting products, services, founders and leadership and all physical attributes. His model considers culture as an observer , characterized in terms of artifacts, values and underlying assumptions.
Hybrid zones can form from secondary contact. A hybrid zone exists where the ranges of two interbreeding species or diverged intraspecific lineages meet and cross-fertilize. . Hybrid zones can form in situ due to the evolution of a new lineage [1] [page needed] but generally they result from secondary contact of the parental forms after a period of geographic isolation, which allowed their ...

In biology, a subculture is either a new cell culture or a microbiological culture made by transferring some or all cells from a previous culture to fresh growth medium. This action is called subculturing or passaging the cells. Subculturing is used to prolong the lifespan and/or increase the number of cells or microorganisms in the culture. [1]
