"Paleoanthropology, also spelled Palaeoanthropology, also called Human Paleontology, interdisciplinary branch of anthropology concerned with the origins and development of early humans. " [R2]

Human evolution on stampIn other worlds, Paleoanthropology or Palaeoanthropology, is a science about human origin and evolution based on fossils record, primitive (flint, stone) tools, artifact and settlement locations. Paleoanthropology studies the prehistoric ancestors of humankind, referred to in a group as hominids.

Palaeoanthropologists .
They dig for fossils in the field, bringing them to universities, labs or museums where they dissect, study and assemble it.
In the field, discovering physical remains and other fossils follows painstaking procedures similar to those archaeologists use when uncovering cultural remains.
Once remains are discovered, they are usually sent to a laboratory or research center where they are carefully studied, using chemical and physical dating methods, X-Rays, MRIs, and other special tools. Paleoanthropologists are most interested in noting how the finds are similar and how they are different from already established ancestral lines [R3]

Results of their study, allows us to restore human evolution tree and make some reconstruction of prehistoric hominids and humans, as represented on many stamps from around the world.
