Chapter 139

Categorized, there appeared protozoa, echinoderms, mollusks, flatworms, annelids, coelenterates, etc.

The species became increasingly prosperous.

And their body size, the largest, was no bigger than a little finger.

At the same time.

They had a common characteristic: no spine.

Therefore, they were also called invertebrates!

Qin Mu stood on the shore, looking at the ocean where one generation of newcomers replaced the old.

He felt happy.

The massive prosperity of invertebrate organisms...

Meant that vertebrate organisms were not far away!

This would be a qualitative leap!

The 350 millionth year.

Invertebrate organisms had already occupied the entire ocean.

Because food was becoming less and less.

Therefore, they were forced to attack each other, using other species as food.

The battle began.

And weak species were destined to not get food or become someone else's meal.

Evolution, under these circumstances, was forced to happen again.

They began to actively arm their body surfaces.

Making their outer shells increasingly hard.

While protecting themselves, they could also hunt better.

Therefore, more and more crustacean organisms appeared.

They...

Became the new round of hegemons.

The 370 millionth year.

Crustacean organisms became more and more numerous, ruling the ocean.

Similarly.

Internal competition began again.

Other species had all become strong.

They couldn't get food again...

Therefore.

Evolution was forced to happen again.

They no longer strengthened their own shells, but strengthened the interior of their bodies.

A spine was quietly generated!

Possessing a spine, they would gain faster speed, stronger digestive ability, and more terrifying bite force.

Among this type of organism, primitive fish led the wave of the era.

Among them.

Placoderms and acanthodians became the new hegemons of marine life because of their strong defense and attack.

The 360 millionth year.

Qin Mu stood before the endless coastline.

He saw the most spectacular scene since evolution began.

This period.

Was also the period of accumulation for all species on Blue Star.

Because of the combined effect of many factors.

In these 10 million years.

Vertebrate organisms underwent earth-shaking changes.

Categorized, tens of thousands of different vertebrate organisms were born.

They filled every part of the ocean, showing different biological potential.

A portion of them...

Even came directly to the coastline, walking toward the land.

Evolving into amphibious reptiles!

Qin Mu stood beside the coastline.

At every moment, he could see a large number of organisms crawling out of the ocean and entering the land.

Like light and shadow.

"This... perhaps can be equated to the Cambrian explosion of life."

Qin Mu took a deep breath and couldn't help but mutter.

Indeed.

The explosion of species diversity during this period had already exceeded all the periods he had evolved before.

Reptiles appeared, active everywhere on land.

Birds flying in the sky also appeared during this period!

They flapped their wings and flew high, soaring in the sky.

Enjoying the blue sky that belonged to them to the fullest. ===== CHAPTER 141 =====
