A
What was a major effect of the closing of the Mediterranean Sea?
It created a large dry salt desert and lowered global temperatures.
Describe the role of tectonic activity in evolution.
It created isolated environments, leading to speciation.
The closing of the Mediterranean Sea created a large __________.
dry salt desert
__________ isolation often led to smaller genetic pools and faster speciation in early human populations.
Geographic
The term “Broad Spectrum Revolution” refers to a period when humans:
A) Developed agriculture and settled in villages.
B) Created specialized hunting tools for large animals.
C) Began diversifying their diet to include small game and plants.
D) Started using fire to cook meat.
C
Mix and match
Pleistocene Epoch - Period of rapid climate shifts and glacial cycles
Out of Africa Hypothesis - Suggests a single origin point for all modern humans
H. sapiens - Known for increased brain size due to protein-rich diets
Broad Spectrum Revolution - Introduced dietary diversity, including small game and plants
Tectonic Activity - Created fragmented landscapes that encouraged speciation
What does the Out of Africa Hypothesis propose about the origins of modern humans?
The Out of Africa Hypothesis proposes that all modern humans originated from a single population in Africa.
It suggests that Homo sapiens evolved in Africa around 200,000 years ago and then migrated to other continents, replacing other hominid populations.
How is the Out of Africa Hypothesis supported?
This theory is supported by genetic evidence, particularly mitochondrial DNA, which points to a common African ancestor known as “mitochondrial Eve.”
