Not Synced
so, we're here in the syner of technology
-
Not Synced
and I just wanted to ask a simple question.
-
Not Synced
What was the greates technological
-
Not Synced
discovery ever made the basis for all
-
Not Synced
subsecuent technology,
-
Not Synced
and when was it made?
-
Not Synced
The gratest technological brakethrough
-
Not Synced
of human beings is language.
-
Not Synced
invented two million years ago
-
Not Synced
in the first and gratest information age
-
Not Synced
by Homo erectus: mom and dad.
-
Not Synced
Homo erectus was one of the most successful
-
Not Synced
crearures who ever walked the earth.
-
Not Synced
The lived on this planet for nearly
-
Not Synced
two million years.
-
Not Synced
We have so far lived on this planet
-
Not Synced
for a certain two hundred thousand,
-
Not Synced
perhabs as many as five hundred thousand.
-
Not Synced
So, we haven't lived the quarter
-
Not Synced
of the time that Homo erectus lived
-
Not Synced
on this planet.
-
Not Synced
Homo erectus was a marvelous creature.
-
Not Synced
Had the gratest brain the wolrd
-
Not Synced
have ever seen, maybe the universe
-
Not Synced
had ever seen.
-
Not Synced
The range of size of the Homo erectus brain
-
Not Synced
was about 950 CC, 75% of the size
-
Not Synced
of an adult Homo sapiens male
-
Not Synced
and roughly in the range of many
-
Not Synced
Homo sapiens female, and that proofs
-
Not Synced
to us that size doesn't matter.
-
Not Synced
The Homo erectus brain and body
-
Not Synced
were both phenomenal.
-
Not Synced
That was the first body Homo erectus
-
Not Synced
stood about as tall as we do.
-
Not Synced
They were probably aorund 150 pounds
-
Not Synced
and they were the first creatures
-
Not Synced
in the history of the universe capable of
-
Not Synced
persistance hunting or bipedal gate
-
Not Synced
enables us to run long distances and
-
Not Synced
cool down more efficiently than quadrupeds.
-
Not Synced
So, Homo erectus was actually able to
-
Not Synced
chase down its prey until the prey
-
Not Synced
either died of heat exhaustion or
-
Not Synced
Homo erectus beat it to dead with
-
Not Synced
a stone axe or club.
-
Not Synced
Homo erectus was a marvelous creature,
-
Not Synced
and they had many accomplishments.
-
Not Synced
Homo erectus made a variety of tools
-
Not Synced
starting with the Olduwan tools and,
-
Not Synced
they kept these tools and they
-
Not Synced
transported these tools and
-
Not Synced
they improved these tools, so they had
-
Not Synced
an upgrade: Acheulean tools
-
Not Synced
and they upgraded this to Levallois tools
-
Not Synced
and each tools was better than the one
-
Not Synced
before, but they weren't limited
-
Not Synced
to stone tools.
-
Not Synced
Homo erectus also made spears wooden
-
Not Synced
tools we have found hundreds of thousands
-
Not Synced
of year old spears, and they made
-
Not Synced
two kinds of sprears. They made spears
-
Not Synced
for throwing and spreasr for thrusting.
-
Not Synced
What does spears for thrusting mean?
-
Not Synced
It means you're a 5 ft 8 to 6 ft 1
-
Not Synced
Homo erectus male 150 lb
-
Not Synced
and you run up and stick that spear
-
Not Synced
into a mastodon.
-
Not Synced
These were first creatures, they were
-
Not Synced
brave creatures and they were
-
Not Synced
extremely intelligent creatures.
-
Not Synced
So, tools were one of the great
-
Not Synced
accomplishments that lets us know
-
Not Synced
what kind brain they were developing.
-
Not Synced
They also had representations of reality.
-
Not Synced
This is a 250,000 year old
-
Not Synced
partally naturally form and
-
Not Synced
partially artificially form by humans
-
Not Synced
by Homo erectus venus. It's called
-
Not Synced
the Venus of Berakhat Ram,
-
Not Synced
and there's some evidence said
-
Not Synced
it was dyed red on certain parts.
-
Not Synced
A shell found on the island of a found
-
Not Synced
in Java, with engravings on the shell
-
Not Synced
by Homo erectus.
-
Not Synced
Homo erectus wasn't simply a toolmaker.
-
Not Synced
they were both makers.
-
Not Synced
They traveled the oceans
-
Not Synced
2 million years ago.
-
Not Synced
How do we know this?
-
Not Synced
Well, the firts island that we find
-
Not Synced
evidence, is the island of Flores in
-
Not Synced
Indonesia, which would have been about
-
Not Synced
a 24 mile boat trip visible from land
-
Not Synced
about the size of the English chanel
-
Not Synced
exept that Flores was then and now
-
Not Synced
surrounded the most treacherous
-
Not Synced
and strongest oceans currents
-
Not Synced
in the world.
