Discovery of
Early Humans
in Africa
History - the story of mankind is divided into two time periods:

The historical period is further
sub-divided into periods:

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

our ancestors.

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, . . .

and pottery.

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.

They lived in the
humid forests of
eastern and
southern Africa.

Australopithecines were probably
nomads who fed on fruits, leaves,
and nuts, as well as fish caught in
streams and meat scavenged from
animals killed by predators.

Earth experienced four long periods of
cold climate known as Ice Ages where
glaciers spread out and covered large
portions of the earth.
Culture
the way of life of a given people at
a given time; it includes . . .
• knowledge
• language
• behavior, diet (laws and dress)
• religious beliefs
• achievements in art and music
Technology is
the skill and
knowledge
used by people
to make tools
and do work.

The period in history before the
advent of writing when people first
learned to fashion tools out of stone
is known as the Stone Age.

Homo Habilis (“human of ability”) are
probably the oldest hominids known to
manufacture tools.

food gatherers,
Homo Erectus
(“human who
walks upright”)
eventually
learned how to
hunt animals.
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.

The Appearance of Homo Sapiens
Neanderthals
were probably
the first Homo
sapiens.
[Image source:

Neanderthals
had brains
that were
slightly larger
than those of
modern
human
beings.
[Image source: http://www10.geocities.com/Athens/6293/hominid.html]
Neanderthals had stocky bodies
with thick bones and very muscular
necks and shoulders.

Tool Use
• The most significant tool
developed were the sickle and
the plow. Both contributed to
the agricultural revolution and
allowed the growth of
civilization.
Other developments
Grinding stone,
ceramic
(pottery/ fired
clay), loom,
wheel,
metallurgy,
Domestication
of animals.
