2. The Day the Universe
Changed
Humans are constantly
seeking answers to the never
ending list of questions they
have. With every answer they
find, another question forms.
With every new answer or
discovery, their perception of
life and the universe change.
For example, Galileo’s
discovery that the Earth
revolves around the sun and
not nice versa completely
altered the way people
viewed the universe.
3. The Day the Universe
Changed
Humans put so much
stock in their beliefs
that they will fight to
the death to defend
them.
History is riddled with
examples of this. Even
to this day we
continue to fight for
our beliefs.
4. The Journey of Man
Everyone in the world is related to each other.
The San tribe is the oldest tribe in the world.
Some of the ancestors of the San tribe eventually left
Africa to journey out to the rest of the world.
Humans went from Africa to Australia to India to China
then on to the rest of the world.
Humans physical features began to change based on
the environment they settled in.
When they went to Europe their skin became light in color
because it was not as hot and it did not need to produce so
much melanin.
5. The Journey of Man
Spencer Wells tracked
the journey of man
through a genetic
marker only found in
the blood of men.
Spencer Wells found
the specific genetic
marker in men through
out Europe, Russia,
North America, South
America, etc.
6. Catastrophe!
During the fifth century there was a catastrophic
event that led to dramatic climate change.
Through a large number of research done, scientists
have deduced that the cause of the climate change
was an enormous volcanic eruption.
The volcano that is the most likely culprit is
Krakatoa which lies between the islands of Java and
Sumatra.
7. Catastrophe!
The three main
scientific methods used
to deduce the source of
the climate change
were tree ring dating,
studying ice cores from
the polar ice caps, and
carbon dating.
8. Catastrophe!
This catastrophic event snowballed into a very devastating time
for human kind. The eruption threw a dense veil of dust, ash or
acid into the atmosphere which blanketed out most of the sun.
This caused temperatures to drop which in turn led to failure in
agriculture.
The failure in agriculture led to starvation and social unrest.
The cold temperatures also allowed the rat population to grow
and in turn allowed the bacteria of the plague to spread.
The initial event caused a domino effect and the sum of all of
the resulting events played a hand in devastating and/or
ending many civilizations through out the world.
9. Guns, Germs, & Steel
Diamond theorizes that Europeans did not thrive
above all others because of superior intelligence or
genetics but because of better opportunities.
The plants and animals in their environment were
much better suited for survival.
They had access to barley, two kinds of wheat, and
flax for textiles.
They also had access to sheep, goats, and cattle for
meat, leather, glue, and wool.
10. Guns, Germs, & Steel
Their grains were much easier to
keep for longer periods of time
which led to food surpluses,
which led to population growth.
Their population growth led to
larger work forces.
Because of the larger work forces,
there were more people to branch
out from farming and hunting to
other occupations such as
crafting and scribing.
These new occupations resulted
in an accelerated economy and
more technological advances
Their advantages in technology
allowed them to defeat other
civilizations with very little effort.
11. Guns, Germs, & Steel
Living in such close proximity to each other and their
domesticated animals caused diseases to spread through
out Europe.
Over time Europeans developed immunities to these
diseases so that they no longer posed as much of a threat.
When Europeans traveled they brought these bacteria and
pathogens with them to places that did not have their
immunities.
These European diseases decimated man indigenous
populations leaving them vulnerable to occupation from the
Europeans.
