The examination of these fossils reveals the morphological and anatomical similarities that are used as a basis of confirming evolution of human beings (Steckley, 2011). Physical anthropologists do proper examination of ancient humans such as anthropoids because they are considered closest to human beings and are mostly linked to evolution.The physical anthropologist selects resources, including the notebook, guides for identifying fossils and textbooks of paleontology. The second step is collecting of fossils from geologic formation from where the anthropologist can access. The anthropologist should select fossils from known or unquestionable sources since they are reliable. These fossils are considered reliable because the environmental contexts from which they originate from are known (Steckley, 2011). The anthropologist should examine the selected fossils carefully using lenses and take notes. The third step involves using field guides to investigate taxonomic identification and scientific classification of the fossils, including their kingdom, phylum, class, order, family, genus and species. The anthropologist then labels the sketches using the guides and textbooks. The anthropologist studies the geologic map of the area where the fossil is found in order to determine the formation and geologic period for the geologic deposit. The anthologist then studies the paleaolecology and paleaoenvironment in which the organism of the fossil lived (Steckley, 2011). The final stage of studying the fossil involves summarizing the fossil’s analysis based on observations and research.The source above deals with the study of jawbones in identifying the evolutionary processes. The book has presents the process of evolution beginning from four billion years, although only a few photographs of jawbones are available for viewing (Duranti, 2010). The introduction of the book defines physical anthropology within the purview of evolution and presents diagrammatic representations of the bones and their changes over varied historical periods. Modern anthropologists, who could be interested in studying physical anthropology, specifically using jawbones as a basis for their study, will find the book useful to them. The selected source, therefore, is important for studying physical anthropology because it defines the terms comprehensively and displays clear diagrammatic presentations.Linguistic anthropology deals with the study of language and its changes over time.
