The anthropologist is mainly interested in describing the specific characteristics of the human species and its varieties and the ways in which they have established themselves. Disciplines related to Anthropology share as their common denominator the study of the natural history of Man and his various populations, whose origin, differentiation, physical and bio-social evolution they thus consider. These disciplines tend towards a synthesis of knowledge acquired to date regarding the biological history of Man and their fundamental themes include such subjects as the biological and molecular characteristics that differentiate present-day populations and the processes underlying their respective adaptations to environmental conditions, the chronology of the processes underlying human evolution, and the collection, classification and analysis of hominid remains, for the purpose of reconstructing the phylogenesis of the species and understanding the processes and mechanisms that have brought about the biological and cultural evolution of man.
Human Paleonutrition, too, is a discipline that aims to define the type of nutrition of ancient human groups through the study of chemical elements present in bones. It takes into account variations in climate and the environment and the economic choices and subsistence strategies of human groups in the past.
