Human Origins in Africa

1. Setting the Stage: Who are we?a. No written history to studyb. Important: The story is not completec. Evolution vs. Creationism- We will not take a side but

simply look at what has been found.

Human Origins in Africa

2. Scientists Search for Human Originsa. Prehistory: Time before written history, roughly

5,000 years agoi. For thousands of years people have recorded information about

their beliefs, activities, and important events using varying forms of written language

ii. Without written records, scientists face many challenges

Human Origins in Africa

b. Scientific Cluesi. Scientists work like detectives uses excavated sitesii. Artifacts: human-made objects such as tool and

jewelry are examined and studiediii. Anthropologists study culture or a people’s unique way of

lifeiv. Paleontologists study fossils or evidence of early life

preserved in rocksv. From these clues anthropologists attempt to recreate a

picture of early human’s cultural behavior

Let’s test this idea

3. The Old Stone Age Beginsa. The invention of tools, mastery over fire and development

of language are believed to have occurred during the Stone Age which has two parts:

i. Paleolithic Age: Old Stone Age roughly 2.5 million B.C. to 8000 B.C.

ii. Neolithic Age: New Stone Age roughly 8000 B.C. to 3000 B.C.

iii. People learned to polish stone tools, make pottery, grow crops and raise animals in New Stone Age

4. Homo habilis, Homo erectus, Neanderthals, Cro-Magnons, and Homo sapiens

a. Timeline on p.8-9b. Developed technology or ways of applying knowledge, tools,

and inventions to meet their needsc. Evolutionists: Missing link?d. Creationists discard this theory

5. New Findings Add to Knowledgea. Fossils, Tools, and Cave Paintingsb. Toumai Skull

i. 7 million year old skull found in northern Chadii. Similar to chimpanzeeiii. Is the skull human or ape? Needs further study

AD actually stands for the Latin phrase "anno domini" which means "in the year of our Lord." The B.C. / A.D. dating system is not taught in the Bible. It actually was not fully implemented and accepted until several centuries after Jesus' death
