In turn, animals provide much of the meat eaten by the human population, whether farmed or hunted, and until the arrival of mechanised transport, terrestrial mammals provided a large part of the power used for work and transport. A variety of living things serve as models in biological research, such as in genetics, and in drug testing.
Human uses of animals include both practical uses, such as the production of food and clothing, and symbolic uses, such as in art, literature, mythology, and religion. All of these are elements of culture, broadly understood. Animals used in these ways include fish, crustaceans, insects, molluscs, mammals and birds.

All living things contain two types of large molecule, proteins and nucleic acids, the latter usually both DNA and RNA: these carry the information needed by each species, including the instructions to make each type of protein. The proteins, in turn, serve as the machinery which carries out the many chemical processes of life.
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 ...
Three medical symbols involving snakes, still used today, are the Bowl of Hygieia symbolizing pharmacy, and the Caduceus and Rod of Asclepius, symbols of medicine. [29] The ouroboros is a widely used symbol, claimed to be related to alchemy. It is depicted as a coiled snake eating its own tail, representing the cycle of life, death and rebirth.
Different societies divide the living world up in different ways. Ethnobiologists attempt to record the words used in particular cultures for living things, from the most specific terms (analogous to species names in Linnean biology) to more general terms (such as 'tree' and even more generally 'plant'). They also try to understand the overall ...
Living technology is the field of technology that derives its functionality and usefulness from the properties that make natural organisms alive (see life).It may be seen as a technological subfield of both artificial life and complex systems and is relevant beyond biotechnology to nanotechnology, information technology, artificial intelligence, environmental technology and socioeconomic ...
