`` Water Making'' Development Story Water Story Part 11 The Birth of Gaia
Assuming that "Life Planet Earth = Gaia" was confirmed to be one life form
Life forms have a history of birth and upbringing,
There is the last death.
When was "Gaia" born?
In the "Gaia hypothesis"
The first life was born on the earth,
After those lives spread all over the globe
It is said that he was born.
What was it like?
Because the atmosphere of the earth before Gaia was born is governed by the laws of the universe.
As we saw earlier, it is "carbon dioxide 99.0%".
Life forms that can live in such an atmosphere
Incorporating carbon dioxide with the sun as an energy source
It is a bacterial microorganism that excretes oxygen.
While increasing the types of such microorganisms
Oxygen increases as it spreads throughout the globe.
Oxygen is a highly reactive gas
Organisms such as life are oxidized and destroyed = die.
When the proportion of oxygen increases so much that it makes it difficult for the bacterial microbial community that uses carbon dioxide to live.
When it faced the earth's first environmental crisis,
It is said that "Gaia" has awakened.
The earth was born 4.5 billion years ago.
The birth of life was 3.6 billion years ago.
It is believed that Gaia's awakening was 2.5 billion years ago.
The young Gaia who awoke
Accumulating various measures to get out of the crisis,
Maintaining the current atmospheric composition after 1.8 billion years
Comprehensive "homeostasis = homeostasis"
Make it up
It has grown into a "life planet Earth = Gaia".
"Gaia has been a lifetime
Only prokaryotic bacteria
Living as a member
Even now, the life of the earth is
Of the most primitive bacteria
Under strong control "
Born 700 million years ago and evolved explosively
The bodies of various current creatures
As a place where indigenous bacteria live
It means that it holds.
From animals, plants, fish, insects and reptiles
Looking at the survival mechanism of all living things,
By indigenous bacterial populations
You can see that it is being utilized.
Being in each of the intestinal bacteria and cells
Mitochondria, which play an important role
Peripheral bacteria that work on the roots of plants
It is a descendant of an indigenous bacterial group.
"Water" has been around since Gaia was born
There is no doubt that it was on Earth.
Moreover, there is no doubt that it existed before the outbreak of life that preceded Gaia.
That means that if there is no water, the life that precedes it
It means that Gaia was never born.
Then to the water itself
Was it the power to generate life?
I can't seem to say that.
Gaia was born where water already existed,
Knowing and utilizing the properties of water,
The current "homeostasis = homeostasis"
It is thought that it was created.
Water is somehow with other substances
The basic properties are different.
First of all, other substances depend on temperature
It changes into gas, liquid, and solid,
The specific gravity of the individual is always the heaviest.
However, only water is lighter in solid form.
Because ice floats on water.
And the heaviest specific gravity is 4 ℃.
If solid water = ice,
If the specific gravity is the heaviest like other substances,
The water on the surface of the earth sinks from the frozen one and all freezes,
Even if it is warmed by the sun, only the surface will melt.
However, ice is lighter than water, so
The water below does not freeze
Creatures can continue to live in it.
The ice age that has existed many times on the earth
Under the ice of the sea, lakes and rivers
I stayed alive.
It is unlikely that Gaia created such a special property of "water."
Secondly, the amount of heat required for ice to become water = melting point
The amount of heat required for water to evaporate = boiling point,
The water is extraordinarily large.
This property of water
To keep the earth in a constant temperature environment
It is very useful.
Rather, if there was no water with such properties
The temperature environment in which living organisms can continue to live
You won't be able to maintain it.
In that sense, the earth is also a water polo.
Third, water has the power to dissolve things
It's unusually strong.
Intermolecular bonds in any substance = positively charged nuclei
It is made by combining negatively charged electrons.
Water has the power of its intermolecular bonds
It has the power to weaken to one hundredth.
And the molecules that were separated
Disperse in water in the form of ions.
Seawater is born by this power
Water containing various minerals is born,
Both plants and animals use nutrients in the form of aqueous solutions
It can be absorbed.
