Composition of the human body not in an essential biological role. The average adult human body contains approximately atoms and contains at least detectable traces of 60 chemical elements. About 29 of these elements are thought to play an active positive role in life and health in humans. The relative amounts of each element vary by individual, mainly due to differences in the proportion of fat, muscle and bone in their body. Persons with more fat will have a higher proportion of carbon and a lower proportion of most other elements (the proportion of hydrogen will be about the same). The numbers in the table
European Society for the study of Human Evolution Max Planck Institute for Evolutionary Anthropology. The main goals of the society are to stimulate and facilitate communication and scientific collaboration between researchers and scientists involved in the study of human evolution, primarily through the organization of conferences, which are held annually in the second half of September. ESHE is dedicated to supporting activities which encourage new and innovative research in the field of human evolution, and is in particular supports the research of young scientists. Each year, ESHE hosts an annual meeting to showcase interdisciplinary research on human evolution from around the world. These meetings are held in the
