2. Ancient African Climate

c. 18,000 BCE to c. 8,000 BCE
• This was a dry period for Africa,
which grew drier over time through
the Younger Dryas period (aka. The
Big Freeze, roughly 10,300 to 9,000
BCE). This was a swiftly developing
ice age that led to very arid
conditions-drier than the even the
map portrays.
• Humans were hunter-gatherers
3. Ancient African Climate

c. 7,500 BCE to c. 3,000 BCE
• A wet period, known as the
Neolithic Subpluvial or Holocene
Wet Phase followed.
• Deserts, including the Sahara,
became grasslands that supported
more humans than it did before or
than it does now.
• The Neolithic or agricultural
revolution occurred.
4. Ancient African Climate
c. 7,500 BCE to c. 3,500 BCE
• This wet period led to a migrations
of people due to more hospitable
conditions.
• As people migrated, they spread
their culture, languages, and
practices (including agriculture).
• The migrations, as represented on
the map, reflect the dispersal of
language we see represented in
modern Africa.

5. Modern African Climate

After c. 3,500 BCE
• The wet period came to an end, and
the climate came to resemble what
it does now.
• The Sahara gradually became a
desert again and the peoples is
supported migrated again to its
edges or perished.
• The development of agriculture
continued and allowed for
settlements that led to cities,
kingdoms, and empires.
6. Climate and Language
• Just as scientist believe humans can
tie their origins to Africa, linguists
believe language originated in Sub-
Saharan Africa.
• The theory is that as humans
spread, language spread and
evolved.
• As changes in climate caused the
people of Africa to migrate,
language spread.

7. Language
• Four language families have been
identified:
1. Afroasiatic
2. Nilo-Saharan
3. Khoisan
4. Niger-Korddofanian/Niger-
Congo
• The language families can be traced
from the Late Stone Age
• The language families were heavily
influenced by the migrations, both
of the African people and outsiders,
as represented by the map.

8. Language
The language families are associated with subsidence methods of the cultures
who spoke them. The methods of subsidence were in part dictated or
encouraged by the climate of the area they inhabited during the wet period.
Afro-Asiatic
Pastoralists and
agropastoralists
Nilo-Saharan
pastoralists
Khoisan
Hunters and gatherers
Niger-Korddofanian/
Niger-Congo
Agriculturalists

• One major unifying characteristic of the group is how the languages is how
numbers are used
