In biology the life history of an organism refers to the reproductive cycle of animals and plants.^[1] Some use the term "alternation of generations" when referring to algae, however as there are in many cases, especially the Rhodophyta, three stages the term "alternation" is not appropriate.

In medicine, a life history may refer to a general health assessment or standard medical history. In seeking to identify certain health patterns, the interviewer may conduct a thorough interview. This form of interview can be utilized to find various kinds of sources for effects on the body and general health.

Main article: Life history theory

Life history theory is an analytic method of sociobiology for understanding reproductive behaviors in animals and people.

In sociological and anthropological research, a life history refers to the overall picture of the informant's or interviewee's life. The purpose of the interview is to be able to describe what it is like to be this particular person, that is, the one being interviewed.

The method was first used when interviewing indigenous peoples of the Americas. The subjects were native American leaders. One interviewed them, and the subjects were asked to describe their lives as such, what it was like to be that particular person. The purpose of the interview was to capture a living picture of a disappearing (as such) people/way of life.

Later the method was used to interview criminals and prostitutes in Chicago. The subjects were asked to tell about their lives. The interviewers also looked at social- and police-records, and the society in general in which the subject lived. The result was a report in which one could read about (i) Chicago at that particular time; (ii) how the subject viewed his own life (i.e. `how it was like to be this particular person') and (iii) how society looked upon the subject what the consequence of this was for that particular person -- i.e. `social work'/-help, incarceration etc.

In both cases, the one doing the interview should be careful not to ask "yes or no"-questions, but to get the subject to tell "the story of his or her life", in his or her own words. It is common practice to begin the interview with the subject's early childhood and to proceed chronologically to the present.
