Bab 10: Chapter 65 Cambrian, life exploded! 【Seven more】
Green, began to spread on land.
under the acceleration of time.
Qin Mu witnessed it from birth, to growth, and then to prosperity.
Just for an instant...
These mosses, gymnosperms, and angiosperms covered the land.
After 250 million years of evolution on this dead planet, a large number of plants finally appeared!
"Original has been consumed by half..."
Qin Mu raised his head.
He glanced at the source that was burning violently in space.
One source can accelerate the world for 500 million years.
According to the current situation.
There are 250 million years left.
According to systematic deduction, it should be enough to evolve intelligent creatures.
Take a deep breath.
Qin Mu continued to observe.
...
Year 260 million.
Plant species are becoming more and more diverse, and tens of thousands of varieties have evolved freely.
and.
Their size, from being short at the beginning, became more and more tall.
to absorb enough sunlight.
They struggle to grow.
In this process, flowers and trees are also generated.
The entire land, from the green at the beginning, has become a colorful color.
Year 270 million.
because of the abundance of plants.

All life-threatening gases in the atmosphere are purified.
The climate environment has also become more and more suitable for life to survive.
It can be said that the emergence of plants made a great contribution to the emergence of living organisms later.
300 millionth year.
The ocean full of blue-green algae finally experienced a mass extinction because of the eutrophication of seawater!
Algae, mass death.
The ocean has become a forbidden zone for plants.
but...
This is also a huge opportunity.
The death of algae itself provides rich nutrients to the ocean.
thereby making...
Single-celled organisms have evolved again!
A brand new, tiny arthropod has appeared!
It roams freely in the ocean, multiplying wildly.
Because there are no natural enemies and sufficient food...
The speed at which it reproduces is astonishing.
This type of arthropod soon became the new overlord of the ocean.
Year 320 million.
Arthropods still haven't eaten up the rich nutrients left by the algae's demise.
Based on the legacy of their predecessors, they continue to evolve.
Divided into categories, there are protozoa, echinoderms, mollusks, flat animals, annelids, coelenterates and so on.
Species are prospering.
And their body size, the largest, is no more than the size of a little finger.
at the same time.
They have one thing in common, they don't have a spine.
Therefore, it is also called an invertebrate!
Qin Mu stood on the coast, watching the ocean where a new generation replaces the old.
A happy look.

The massive flourishing of invertebrates...
It means that the spine creature is not far away!
This will be a qualitative leap!
...
Year 350 million.
Invertebrates have taken over the entire ocean.
Because food is getting less and less.
So they are forced to attack each other and feed on other species.
The battle begins.
And weak species are destined to eat no food, or become someone else's plate.
Evolution, in this case, is forced to happen again.
They began to actively arm their body surface.
Make your shell harder and harder.
While protecting yourself, you can also hunt better.
So more and more crustaceans appeared.
they...
Become a new round of hegemony.
Year 370 million.
Crustaceans are growing in abundance and dominating the oceans.
same.
The involution starts again.
Other species are stronger.
They can't eat anymore...
so.
Evolution is forced to arise again.
Instead of strengthening their own outer shell, they strengthen the inside of the body.
The spine is quietly generated!
With a spine, they will gain faster speed, better digestion, and a more terrifying bite.

Among such creatures, primitive fish led the tide of the times.
in.
Due to their powerful defenses and attacks, placodes and spiny fish have become the new overlords of marine life.
Year 360 million.
Qin Mu stood in front of the endless coastline.
I saw the most spectacular scene in the evolution for so long.
this time.
It is also a period of accumulation and growth of all species on the Blue Star.
due to the combined effect of many factors.
during these millions of years.
Spinal creatures have undergone tremendous changes.
Divided into categories, tens of thousands of different vertebrate creatures were born.
They populate the oceans and exhibit different biological potentials.
Part of it...
It even came directly to the coastline and walked towards the land.
Evolved into an amphibious reptile!
Qin Mu is standing next to the coastline.
At every moment, a large number of creatures can be seen crawling out of the ocean and into the land.
Like light and shadow.
"This... may be equivalent to the explosion of life in the Cambrian period."
Qin Mu took a deep breath and couldn't help muttering.
indeed.
The explosion of species diversity in this period has surpassed all previous periods of his evolution.
Reptiles appeared and were active on land.
Birds flying in the air also appeared in this period!
They fly high and soar in the sky.
Enjoy the blue sky that belongs to them. *
