Title: Early%20Humans
1Early Humans
- Ch. 1 Sec. 1 Outline
- World Studies
2Before History
- The time before the written word is called
prehistory. - It is difficult for historians to know what
happened before writing because there wasnt a
conscious effort to save it. - A lot of what we know about prehistory are based
on theories developed by looking at artifacts.
3How we know about prehistory?
- Studying the objects left by humans to determine
how they lived. - Dig in the earth to uncover artifacts like tools,
weapons, art and housing
- Studying human life and culture by studying
fossils (surviving biological remains) in order
to create a picture of their daily lives.
4How do they do it?
- To locate artifacts and fossils, archaeologists
and anthropologist excavate at historical sites
around the world to uncover fossil remains,
buildings, burial grounds, and any other object
that can inform them of life and society of that
time.

Seeds found in ancient toilet
Hand Axe 250,000 years old
Flute 35,000 years old
6If you were an archaeologist or anthropologist
- If you discovered this, what would it tell you?
7How do they date the artifacts?
- Knowing when something is from is vital to
understand history. If you date it incorrectly,
it could have a major impact on history. - RADIOCARBON DATING all living things absorb
radioactive carbon (C-14) from the atmosphere.
When it dies, it slowly loses C-14. By measuring
the amount left in an object, you can determine
its age (up to 50,000 years old) AKA Carbon
Dating
8Dating older objects
- If an object is older than 50,000 years,
scientist can make a relatively precise
measurement using thermo luminescence. In this
technique, scientist measure the soil around a
fossil and measure the amount of light given off
by the electrons trapped. - Used with pottery, stones, gems, etc
9Additional ways to acquire info
- Microscopic and biological analysis of organic
remains, left on items can give scientist even
more information. For example, blood found on a
tool can tell us what type of animals were alive
and provide DNA for humans. Organic remains on a
dinosaur tooth can tell you what the dino ate.
10Early Development
- Hominids were humanlike creatures. They walked
upright and changed slowly over time. They
existed millions of years ago
11Early Hominids
- Lucy - Australopithecus
- The earliest hominid discovered was Lucy.
- About 3.5 million years old
- Small head (small brain cavity)
- No evidence of use of tools
- Homo Habilis Handy Human
- 2.5 to 1.6 million years ago
- May have used tools (handy)
- Homo Erectus Upright Human
- 1.8 million to 100,000 years ago
- Arms and legs in modern human proportion
- Probably the first to leave Africa
12Homo Sapiens
- Around 200,000 years ago, Homo Sapiens, or wise
human roamed the earth - Charateristics of Homo Sapiens
- Larger brain
- Mastered fire
- Two early humans came from Homo Sapiens
- Neanderthals
- German orgins
- Lived between 100,000 and 30,000 B.C.
- Located in Turkey and other European countries
- Made clothes
- Homo Sapiens Sapiens
- wise, wise human
- First to have an anatomy similar to people today
- First appeared in Africa between 150,000 to
200,000 years ago. - Out-of-Africa theory has Homo Sapiens Sapiens
moving to other parts of the world
13How did people get here?
- Out-of-Africa theory about 100,000 years ago,
Homo Sapiens Sapiens left Africa for other parts
of the world. They replaced the previous
populations that are no longer around. AKA
Replacement Theory - Multiregional model development from earlier
hominids to anatomically (physically) modern
humans in different locations in Africa, Asia,
and Europe.
14Homo Sapiens Sapiens replace Neanderthals
- 30,000 B.C., Neanderthals had been replaced by
Homo Sapiens Sapiens (possibly due to conflict). - Homo Sapiens Sapiens begin to move about the
world, populating, and establishing roots for our
existance. - All human beings today belong to the same
subgroup of humans. Whether you are European,
Asian, Austrailian, African, or Aboriginies
(original inhabitants) we all come from the same
orgins.
15The Paleolithic Age
- One of the basic features that distinguishes
humans from other species is the ability to make
tools. - The term Paleolithic Age is used to designate the
early period of human history (approximately
2,500,000 B.C. to 10,000 B.C.) in which humans
used simple stone tools.
16Survival
- People survived on hunting and gathering for
their daily food. - Because of this, they had a close relationship
with their environment and understood what
animals to hunt and plants to eat.
- Plants
- Wild Nuts
- Berries
- Fruits
- Wild Grains
- Green Plants
- Animals
- Buffalo
- Horses
- Bison
- Reindeer
- Fish
- Shellfish
17Life in the Paleolithic Age
- Using stone tools allowed for early humans to
survive. - They used hard stones, like flint, to chip away
at another stone, to shape it for use. Hand axes
were the most common. - Early humans also figured out how to attach a
wooden handle to a stone to make it easier to
use. - They also attached poles to spear points, that
placed in fire to make harder, to make weapons
that could kill large animals.
18Improved Technology
- As more and more generations passed, Paleolithic
hunters developed better tools. - The invention of the spear, and later the bow and
arrow, made hunting much easier. - Harpoons and fishhooks, made of bone, increased
the catch of fish. - Sharp tools could be used to cut up plants, dig
roots, and cut branches to build simple
shelters. - They used tools to scrape the hides of animals
for clothing and shelter. - There is evidence that by the end of the
Paleolithic Era, bone needles were used to create
nets, sew hides, and weave baskets.
19Nomads
- Since the humans in the Paleolithic Age were
hunters and gatherers, they had to always find
food (they didnt grow food). They followed the
food (animal migrations and vegetation cycles). - They were nomads (didnt have a set home moved
from place to place to survive).
20Roles of Men and Women in Paleolithic Age
- The main job of both men and women was to find
food. - Women gathered nuts, berries, roots, and grains.
- Women bore and raised the children. Teaching the
children what was edible. - Women trapped small animals and kept the camp
safe. - Men were the hunters, going far distances looking
for game to kill. - It is believed that both men and women held equal
responsibility for survival. - It is likely they made joint decisions.
21Adapting to Survive
- To avoid cold, many Paleolithic humans found
shelter in caves. - Others learned how to make simple structures made
of wood and animal hide. - If wood was scarce, they might use large mammoth
bones as the structure support.
22Fire, Fire, Fire!!!
- The use of fire provided light, heat, and
protection. - Homo Erectus were the first people who learned
how to make fire (500,000 years ago). - Fire was also used to hunt, scaring wild animals
to run towards the hunters. - Fire allowed for food to be cooked. Cooked food
tasted better, lasted longer, and was easier to
chew and digest. - Because of fire, and cooked food, nutrition
improved.
23Fire and Ice!!!
- The ability to make fire became crucial to
survival during the Ice Age. - About 100,000 B.C. started the most recent Ice
Age, ending about 8,000 B.C. - Sheets of thick ice covered large parts of
Europe, Asia, and North America. - Sea levels lowered and people were able to cross
land bridges to other continents.
24Cave Art
- Art is everywhere.
- Paleolithic humans depicted art scenes on cave
walls. They would burn animal fat to see in the
dark caves. - Lascaux, France, Altamira, Spain, southern France
are some of the most famous examples of Cave Art. - Artist painted with their fingers and twigs.
They also blew paint through hollow reeds. - Mixed mineral ores with animal fats to make red,
yellow, and black paint. - Very few humans appear in the cave art, mostly
animals. When humans do appear, they usually
appear as stick figures. - Some believe cave art was to help appease the
gods and help in the hunt. Others think they were
just for pleasure.
25Examples of Cave Art
Southern France
- In 1994, Jean-Marie Chauvet, and his friends,
discovered paintings in a cave - There paintings were nearly twice as old as the
others and more advanced
- Discovered in 1940
- A storm uprooted a tree that revealed a cave
- Children playing nearby discovered the paintings
inside
- A little girl discovered a cave on her
grandfathers farm in 1879 - Evidence that the paintings were done at
different times - Earlier art was crude and the later are more
detailed
