1) The subfields of anthropology seem quite diverse in their specific subjects and methods. Why‚ then‚ are they all considered parts of the single discipline of anthropology? What ties them together?

Together‚ all four sub-fields make up the discipline of anthropology. Each sub-field studies humans and

They belong to a species called Australopithecus ramidus (5-4 million years BCE). In Handar Valley Ethiopia‚ a slightly more advanced creature was detected. The material discovered was three million years old including ’Lucy’ a bipedal hominid whose skeleton was found 40% complete. The remains show a picture of a small‚ slender but strong hominid‚ whose pelvis and lower limb bones were no larger than those of apes‚ the teeth still retained signs of ape ancestry. Lucy had similar teeth to modern Homo
