Anthropology, Physical
Natural History
A former branch of knowledge embracing the study, description, and classification of natural objects (as animals, plants, and minerals) and thus including the modern sciences of zoology, botany, and mineralogy insofar as they existed at that time. In the 17th, 18th, and 19th centuries it was much used for the generalized pursuit of certain areas of science. (Webster, 3d ed; from Dr. James H. Cassedy, NLM History of Medicine Division)
History, Medieval
The period of history from the year 500 through 1450 of the common era.
Romania
I'm sorry for any confusion, but "Romania" is a country located in southeastern Europe, not a medical term. It is not possible to provide a medical definition for it.
Neanderthals
Archaeology
The scientific study of past societies through artifacts, fossils, etc.
Africa
I'm afraid there seems to be a misunderstanding - "Africa" is not a medical term and does not have a medical definition. Africa is the world's second-largest and second-most populous continent, consisting of 54 countries with diverse cultures, peoples, languages, and landscapes. If you have any questions related to medical topics or definitions, I would be happy to help answer those for you!

Retrospective Studies
Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.
Family Health
Case-Control Studies
Studies which start with the identification of persons with a disease of interest and a control (comparison, referent) group without the disease. The relationship of an attribute to the disease is examined by comparing diseased and non-diseased persons with regard to the frequency or levels of the attribute in each group.
Prospective Studies
Follow-Up Studies
Prevalence
Haplotypes
Cohort Studies
Studies in which subsets of a defined population are identified. These groups may or may not be exposed to factors hypothesized to influence the probability of the occurrence of a particular disease or other outcome. Cohorts are defined populations which, as a whole, are followed in an attempt to determine distinguishing subgroup characteristics.

Phylogeography

Age Factors
Age as a constituent element or influence contributing to the production of a result. It may be applicable to the cause or the effect of a circumstance. It is used with human or animal concepts but should be differentiated from AGING, a physiological process, and TIME FACTORS which refers only to the passage of time.
Reproductive History
An important aggregate factor in epidemiological studies of women's health. The concept usually includes the number and timing of pregnancies and their outcomes, the incidence of breast feeding, and may include age of menarche and menopause, regularity of menstruation, fertility, gynecological or obstetric problems, or contraceptive usage.
