WEBVTT

99:59:59.999 --> 99:59:59.999
so, we're here in the syner of technology

99:59:59.999 --> 99:59:59.999
and I just wanted to ask a simple question.

99:59:59.999 --> 99:59:59.999
What was the greates technological

99:59:59.999 --> 99:59:59.999
discovery ever made the basis for all

99:59:59.999 --> 99:59:59.999
subsecuent technology,

99:59:59.999 --> 99:59:59.999
and when was it made?

99:59:59.999 --> 99:59:59.999
The gratest technological brakethrough

99:59:59.999 --> 99:59:59.999
of human beings is language.

99:59:59.999 --> 99:59:59.999
invented two million years ago

99:59:59.999 --> 99:59:59.999
in the first and gratest information age

99:59:59.999 --> 99:59:59.999
by Homo erectus: mom and dad.

99:59:59.999 --> 99:59:59.999
Homo erectus was one of the most successful

99:59:59.999 --> 99:59:59.999
crearures who ever walked the earth.

99:59:59.999 --> 99:59:59.999
The lived on this planet for nearly

99:59:59.999 --> 99:59:59.999
two million years.

99:59:59.999 --> 99:59:59.999
We have so far lived on this planet

99:59:59.999 --> 99:59:59.999
for a certain two hundred thousand,

99:59:59.999 --> 99:59:59.999
perhabs as many as five hundred thousand.

99:59:59.999 --> 99:59:59.999
So, we haven't lived the quarter

99:59:59.999 --> 99:59:59.999
of the time that Homo erectus lived

99:59:59.999 --> 99:59:59.999
on this planet.

99:59:59.999 --> 99:59:59.999
Homo erectus was a marvelous creature.

99:59:59.999 --> 99:59:59.999
Had the gratest brain the wolrd

99:59:59.999 --> 99:59:59.999
have ever seen, maybe the universe

99:59:59.999 --> 99:59:59.999
had ever seen.

99:59:59.999 --> 99:59:59.999
The range of size of the Homo erectus brain

99:59:59.999 --> 99:59:59.999
was about 950 CC, 75% of the size

99:59:59.999 --> 99:59:59.999
of an adult Homo sapiens male

99:59:59.999 --> 99:59:59.999
and roughly in the range of many

99:59:59.999 --> 99:59:59.999
Homo sapiens female, and that proofs

99:59:59.999 --> 99:59:59.999
to us that size doesn't matter.

99:59:59.999 --> 99:59:59.999
The Homo erectus brain and body

99:59:59.999 --> 99:59:59.999
were both phenomenal.

99:59:59.999 --> 99:59:59.999
That was the first body Homo erectus

99:59:59.999 --> 99:59:59.999
stood about as tall as we do.

99:59:59.999 --> 99:59:59.999
They were probably aorund 150 pounds

99:59:59.999 --> 99:59:59.999
and they were the first creatures

99:59:59.999 --> 99:59:59.999
in the history of the universe capable of

99:59:59.999 --> 99:59:59.999
persistance hunting or bipedal gate

99:59:59.999 --> 99:59:59.999
enables us to run long distances and

99:59:59.999 --> 99:59:59.999
cool down more efficiently than quadrupeds.

99:59:59.999 --> 99:59:59.999
So, Homo erectus was actually able to

99:59:59.999 --> 99:59:59.999
chase down its prey until the prey

99:59:59.999 --> 99:59:59.999
either died of heat exhaustion or

99:59:59.999 --> 99:59:59.999
Homo erectus beat it to dead with

99:59:59.999 --> 99:59:59.999
a stone axe or club.

99:59:59.999 --> 99:59:59.999
Homo erectus was a marvelous creature,

99:59:59.999 --> 99:59:59.999
and they had many accomplishments.

99:59:59.999 --> 99:59:59.999
Homo erectus made a variety of tools

99:59:59.999 --> 99:59:59.999
starting with the Olduwan tools and,

99:59:59.999 --> 99:59:59.999
they kept these tools and they

99:59:59.999 --> 99:59:59.999
transported these tools and

99:59:59.999 --> 99:59:59.999
they improved these tools, so they had

99:59:59.999 --> 99:59:59.999
an upgrade: Acheulean tools

99:59:59.999 --> 99:59:59.999
and they upgraded this to Levallois tools

99:59:59.999 --> 99:59:59.999
and each tools was better than the one

99:59:59.999 --> 99:59:59.999
before, but they weren't limited

99:59:59.999 --> 99:59:59.999
to stone tools.

99:59:59.999 --> 99:59:59.999
Homo erectus also made spears wooden

99:59:59.999 --> 99:59:59.999
tools we have found hundreds of thousands

99:59:59.999 --> 99:59:59.999
of year old spears, and they made

99:59:59.999 --> 99:59:59.999
two kinds of sprears. They made spears

99:59:59.999 --> 99:59:59.999
for throwing and spreasr for thrusting.

99:59:59.999 --> 99:59:59.999
What does spears for thrusting mean?

99:59:59.999 --> 99:59:59.999
It means you're a 5 ft 8 to 6 ft 1

99:59:59.999 --> 99:59:59.999
Homo erectus male 150 lb

99:59:59.999 --> 99:59:59.999
and you run up and stick that spear

99:59:59.999 --> 99:59:59.999
into a mastodon.

99:59:59.999 --> 99:59:59.999
These were first creatures, they were

99:59:59.999 --> 99:59:59.999
brave creatures and they were

99:59:59.999 --> 99:59:59.999
extremely intelligent creatures.

99:59:59.999 --> 99:59:59.999
So, tools were one of the great

99:59:59.999 --> 99:59:59.999
accomplishments that lets us know

99:59:59.999 --> 99:59:59.999
what kind brain they were developing.

99:59:59.999 --> 99:59:59.999
They also had representations of reality.

99:59:59.999 --> 99:59:59.999
This is a 250,000 year old

99:59:59.999 --> 99:59:59.999
partally naturally form and

99:59:59.999 --> 99:59:59.999
partially artificially form by humans

99:59:59.999 --> 99:59:59.999
by Homo erectus venus. It's called

99:59:59.999 --> 99:59:59.999
the Venus of Berakhat Ram,

99:59:59.999 --> 99:59:59.999
and there's some evidence said

99:59:59.999 --> 99:59:59.999
it was dyed red on certain parts.

99:59:59.999 --> 99:59:59.999
A shell found on the island of a found

99:59:59.999 --> 99:59:59.999
in Java, with engravings on the shell

99:59:59.999 --> 99:59:59.999
by Homo erectus.

99:59:59.999 --> 99:59:59.999
Homo erectus wasn't simply a toolmaker.

99:59:59.999 --> 99:59:59.999
they were both makers.

99:59:59.999 --> 99:59:59.999
They traveled the oceans

99:59:59.999 --> 99:59:59.999
2 million years ago.

99:59:59.999 --> 99:59:59.999
How do we know this?

99:59:59.999 --> 99:59:59.999
Well, the firts island that we find

99:59:59.999 --> 99:59:59.999
evidence, is the island of Flores in

99:59:59.999 --> 99:59:59.999
Indonesia, which would have been about

99:59:59.999 --> 99:59:59.999
a 24 mile boat trip visible from land

99:59:59.999 --> 99:59:59.999
about the size of the English chanel

99:59:59.999 --> 99:59:59.999
exept that Flores was then and now

99:59:59.999 --> 99:59:59.999
surrounded the most treacherous

99:59:59.999 --> 99:59:59.999
and strongest oceans currents

99:59:59.999 --> 99:59:59.999
in the world.

99:59:59.999 --> 99:59:59.999
