Anthropologists and sociologists often assume that human beings have natural social tendencies but that particular human social behaviours have non-genetic causes and dynamics (i.e. people learn them in a social environment and through social interaction).
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] Cultural evolution is the change of this information ...
Human interactions with microbes include both practical and symbolic uses of microbes, and negative interactions in the form of human, domestic animal, and crop diseases. Practical use of microbes began in ancient times with fermentation in food processing ; bread , beer and wine have been produced by yeasts from the dawn of civilisation, such ...
Bioculture is the combination of biological and cultural factors that affect human behavior. [1] It is an area of study bounded by the medical sciences, social sciences, landscape ecology, cultural anthropology, biotechnology, disability studies, the humanities, and the economic and global environment.
Microorganisms, or microbes, span all three domains of life – bacteria, archaea, and many unicellular eukaryotes including some fungi and protists.Typically defined as unicellular life forms that can only be observed with a microscope, microorganisms were the first cellular life forms, and were critical for creating the conditions for the evolution of more complex multicellular forms.
The term "sociocultural system" embraces three concepts: society, culture, and system. A society is a number of interdependent organisms of the same species. A culture is the learned behaviors that are shared by the members of a society, together with the material products of such behaviors.
Furthermore, the term culture is more generally used informally to refer to "selectively growing" a specific kind of microorganism in the lab. It is often essential to isolate a pure culture of microorganisms. A pure (or axenic) culture is a population of cells or multicellular organisms growing in the absence of other species or types.
Microbial food cultures are live bacteria, yeasts or moulds used in food production. Microbial food cultures carry out the fermentation process in foodstuffs. Used by humans since the Neolithic period (around 10 000 years BC) [1] fermentation helps to preserve perishable foods and to improve their nutritional and organoleptic qualities (in this case, taste, sight, smell, touch).
