Anthropologists study human development and culture. Paleoanthropologist Anthropologists study human development and culture. Paleoanthropologists specialize in studying the earliest hominids. The prefix paleo means ancient.

First Discovery of Hominid 1974 – Donald Johnson discovered a partial skeleton in Africa. Johnson found a piece of a skull, a jawbone, a rib, and leg bones. After careful analysis, Johnson concluded that the bones belonged to a female hominid who lived more that 3 MILLION years ago. Johnson called her Lucy.

Aus-tra-lo-pi -the-cus Af-ar-en-sis An African anthropologist called the earliest known group of hominids aus-tra-lo-pi-the-cus which means southern ape. The second part of the name refers to the Afar Triangle – the part of Africa where Lucy was found. Scientists learned about early hominids by studying Lucy. After assembling her bones, scientists discovered that Lucy was short compared to most humans .

Lucy Approximately three feet tall Had a mix of ape like and human features Long arms Hands and feet were similar to modern humans Large head Forehead and jaw stuck out from head

Check For Understanding What were some characteristics of Lucy?

Other remains similar to Lucy were found in Afar Triangle. Lucy and Her Relatives Other remains similar to Lucy were found in Afar Triangle. Scientists guess that Lucy’s lived in Africa about 3 to 4 million years ago.

How Are Hominids Like Lucy Related to Later Hominids and Humans Today? Anthropologists often disagree about the answer to this question. One reason – there are very few clues available Bones as old as Lucy’s are difficult to find Scientists do agree that Lucy and her relatives are the very early forms of humans.

Discoveries About Lucy After studying Lucy’s skeleton, scientists discovered that she was biped. The prefix bi means two. Biped means she walked on two feet. This was an advantage for Lucy and her relatives. With their hands free: They were able to gather and carry food more easily. They were also better able to defend themselves and their children.

Check For Understanding What does the prefix bi mean? What does biped mean? What were two advantages of Lucy and her relatives having their hands free?

How Are Early Hominids Different From Modern Humans? Lucy’s brain was one-third the size of ours. Scientists have found no tools from Lucy’s time. They also do not believe that these early hominids were able to talk.

Agenda Review of Previous Lesson 10 minutes Australopithecus Afarensis Direct Instruction 20 minutes Handy Man Share Out/Reflection 5 minutes Wrap Up 5 minutes

Homo Habilis: Handy Man Homo Habilis is the second group of hominids. They were discovered in Africa by Louis and Mary Leakey. Handy Man lived approximately 1.5 to 2 million years ago. Like Lucy the Homo Habilis had both ape like and human like features. They walked on two feet. But they were taller than Lucy. Their features were more human like Their brains were twice the size of Lucy’s.

Homo Habilis: Handy Man Scientists found bones of more than one Homo Habilis together. This suggests that the Handy Man hominids lived in groups. Living with others would have helped them survive. They could work together and protect themselves against animal attacks. They could also collect food over larger areas of land.

Handy Man: Toolmaker Had a larger brain. Were more advanced than the Australopithecus Afarensis. Tools were found with this hominid group. Ability to make tools allowed the Handy Man group to live better and longer than hominids like Lucy.

Handy Man: Toolmaker Discussion What type of planning did this hominid group have to engage in, in order to create the tools they needed? How do scientists believe the Handy Man hominid group used these tools?

Agenda Review of Previous Lesson - Handy Man vs Australopithecus Afarensis 10 minutes Direct Instruction - Upright Man – Neanderthal - Homo Sapiens Sapiens - Early Modern Humans 30 minutes Group Activity – Determine which scientists are needed address the issue discussed in the prompt 20 minutes Assessment Chapter 2 30 minutes Review of Assessment 15 minutes Wrap Up 5 minutes

Homo Erectus: Upright Man This group had been around longer than the Australopithecus Afarensis and Homo Hablis. This hominid group was discovered in 1891 in Java, Asia. The Upright Man has been around longer than any other hominid group. Scientists believe they were the first hominid group to migrate out of Africa. They were taller and thinner than earlier hominids. The face of the Upright Man was more like modern humans.

Homo Erectus: Upright Man Had larger brains than the Handy Man. They were also toolmakers who made more complex tools. Greatest advantage of this group is that they had the ability to use fire. It is unclear as whether they were hunters. Scientists believed that they were nomadic and built shelters where they traveled. Scientists also believed that the Upright Man’s ability to use fire and build shelter allowed them to live longer and travel further than earlier hominid groups.

What did scientists infer about the Upright Man’s ability to use fire? Discussion What did scientists infer about the Upright Man’s ability to use fire? How did this ability enhance their lives?

Homo Sapiens Neanderthalensis: Neanderthals Discovered in 1856 in Germany. Lived after the Upright Man. They lived in Africa, the Near East, Europe, and parts of Asia. Walked upright Were shorter and stockier than modern humans. Stronger than other hominid groups. Had large brains. They used their intelligence to become more skilled toolmakers.

Homo Sapiens Neanderthalensis: Neanderthals Scientists believed that this hominid group were also able to better survive because they worked together. Scientists also inferred: That they were they first hominid group to hunt in an organized group. Had a sense of community

Discussion What evidence did the scientists use to support the thought that the Neanderthals had a sense of community?

Homo Sapiens Sapiens: Early Modern Humans Most scientists believe that this group originated from Africa. They were discovered in 1879. They migrated to Europe, Asia, Australia, North America, and South America. They survived because of their ability to create better tools, shelter, and clothing.

How did these tools enhance their lives? Discussion How were the Homo Sapiens Sapiens more skilled in their tool making abilities than the Neanderthals? How did these tools enhance their lives?

Early Modern Humans: The First Artists Recorded their lives through art. They also made musical instruments. Some images may have been animals they hunted as well as mythical creatures they imagined.

Why did the early modern humans create art? Discussion Why did the early modern humans create art? How did the early modern humans ability to express feelings through art contribute to their development?
