This program is brought to you by the Ogawa Seiki, a company that is familiar with the world's OS engines.
In 1911, the first small engine was released in Japan and it was exported to the United States. In 1913, the engine was developed.
In the next few years, the company has been looking at the small engines and is walking on this road. The OS engine is already leading the world of small engines.
The first small engine was developed in Japan and it was exported to the United States.
Today, I would like to talk about the history of the Earth, starting with fossils. Today's speaker is Professor Hiroya Goto, a professor at the Department of Education at Kobe University.
Today, we have a lot of fossils in this room. There are fossils, and it is very romantic to see the animals and plants that have been seen for hundreds of millions of years.
We don't really know how old they are, but we would like to compare the history of the Earth with these fossils.
Let's say that the first zero is now. Let's say that the red one, the one that says 100, was 10 billion years ago. And then 20 billion years ago, 30 billion years ago.
Let's do it like this. Then, how old is the birth of the Earth?
The birth of the Earth is 4.5 billion years ago.
So, what was the first creature that was born after the birth of the Earth?
This is a fossil from South Africa, and it is about 3.5 billion years old.
And then there are a lot of fossils, but the most representative is the fossil of the three-headed
How long ago was this discovered?
This is about 600 million years ago.
This fossil is about 600 million years old.
How old is the human race?
For example, if we go with this, it will be 10 million years.
Then, even if we go from the top of the fossil, we can find fossils that are about 1 millimeter long.
Is it 1 millimeter?
But, it's a little more, and it's a human race, and this is about 0.7 millimeters.
I'd like you to show me the fossils.
The most popular fossil is the three-headed.
There are a lot of them.
The three-headed was very popular at the time.
So, the ones that lived in a very good environment became very large.
And the ones that didn't are relatively small.
Or, the three-headed evolved gradually.
The ones that were made later on were generally larger.
There's this one, too.
There's a lot of them.
Where did you find this one?
This one is from the UK.
And?
This one is also from the UK.
The smaller one?
I'd like you to see the Japanese fossil, but unfortunately, there are very few three-headed fossils in Japan.
Have there ever been?
Yes, there have been.
So, the three-headed was all over the world?
That's right.
So, it's been wiped out, or it's been wiped out.
What does this mean?
This is a research that's important to do.
I've collected fossils and made them into a book.
I thought, what kind of woman is this?
That's right.
The purpose of the research is to see how these organisms were born and evolved.
Another important thing is to see how we, living now, can survive.
The fossils tell us a lot about that.
How many millimeters was the three-headed one?
The three-headed one is about five centimeters.
Five centimeters is a lot.
That's right. It's a lot.
Five or three hundred million years?
Yes, five or six hundred million years.
The first one that came out was about six hundred million years ago.
Compared to the three-headed, the human race is still like a child.
That's right. They're like big seniors.
Why did the three-headed one fall?
There are many questions about this.
One is that I've been a very bad person.
My body gets bigger and bigger.
And I can't close my eyes unless I'm in a place like this.
That's how it changes.
The other thing is that when more and more organisms come out,
animals come out of their nests.
What is that?
That's one of the ancestors of the three-headed one.
Three-headed?
Yes.
They're very scary.
They have poison.
They still have poison.
Yes, they still have poison.
The situation has changed, but some of them are still alive.
Of course, this was in the sea at the time.
In the sea?
Yes.
Let me show you a little bit of that.
For example, this is the one aiming for the three-headed one.
This is the one that's been lured.
That's right.
Can you see it?
It looks like it.
Can you see it?
How is it?
This is the one.
This is the one that was lured by the three-headed one.
There's another thing that's very hard to find in fossils.
This is a fossil called a right-angled stone.
It's a line of octopus and squid.
It looks like a squid with a long head.
That's right.
It looks like it was caught by the three-headed one with this long arm and ate it.
So when these things come out, the three-headed one suddenly falls.
I see.
It suddenly falls.
So when you say human, what does it mean to be a human
and what does it mean to be a human?
It means that you're a human.
