The historical period is further sub-divided into periods: Circa 5,500 years ago Pre-history Before Christ History 0 Anno Domini Anno Domini means “In the year of the Lord” Hominid • member of the group that includes human beings and earlier humanlike creatures Anthropologists study primitive cultures in an effort to understand I’ll call you our ancestors. the poop Eaters. The discipline of Anthropology can be divided into two fields: Physical Compare bones and other fossil remains looking for changes in such features as the brain and posture. Cultural Study artifacts and cultural characteristics of humans and their ancestors. Paleontologists are scientists who study fossil remains. Archaeologists are scientists who study earlier peoples and cultures. Artifacts are objects made or used by humans, such as tools, . . . ornaments, Source: Biblical Archaeology Review, January/February 2000, p. 19. and pottery. Source: Biblical Archaeology Review, January/February 2000, p. 35. Archaeologists often dig into midden piles to learn about past cultures. Distinctive designs identify which canned beverages the tab opened. Tab quantities indicate the popularity of each beverage. The brief time in which each tab design was manufactured helps date samples. Radiocarbon Dating • a modern scientific method for telling the age of once-living material by measuring the amount of radioactive carbon remaining in it Japanese paleontologist Gen Suwa found one of the oldest hominid teeth at a site near Aramis, Ethiopia, in 1972. Suwa and Tim D. White of the University of California eventually unearthed the remains of 17 individuals believed to have lived 4.4 million years ago. Lucy was the most nearly complete skeleton of any erectwalking pre-human found. This find has recently been called into question by new scholarship. It may not be (pre)human. As scientist unearth more clues, newer evidence may require them to reinterpret older evidence. Many scientists believe that Australopithecus (“southern ape”) was the first prehuman hominid.

Paleolithic Mesolithic Neolithic Old Stone Age Middle Stone Age New Stone Age Homo Habilis (“human of ability”) are probably the oldest hominids known to manufacture tools.

Distribution of Homo erectus remains. Scientists disagree on when prehistoric peoples left Africa and moved to other parts of the world. Language made it possible to trace the migration of people.
