In the 2.85 million year of the Protozoan Period, some animals were at a disadvantage in the process of marine evolution.
One is to find a new living environment, and the other is under Tian Dao's interference.
Then, following plant life, they also gradually evolved organs for landing on land and surviving.
The life in the primordial world completed the evolutionary process of life on Earth that took billions of years in just over two million years.
Of course, the evolution of life is not all smooth sailing.
Just like the disasters that caused the previous two mass extinctions of life.
During these millions of years, life on the primordial Continent has encountered several major crises and disasters.
Some of these disasters were caused by people allowing their own actions to happen naturally.
For example, countless huge meteorites with diameters of tens of thousands of kilometers fall from the sky, causing all kinds of horrific disasters across an entire sea area.
World-destroying tsunamis, volcanic eruptions, continental plate shifts, earthquakes...
Thus, a small-scale extinction of life similar to the extinction of the dinosaurs on Earth occurred;
Another example is the periodic changes in natural climate, with large and small ice ages coming one after another, freezing everything;
Or perhaps cosmic ray bursts pass through mountains, seas and continents from time to time, wiping out countless lives in an area, and so on.
There are also mass extinctions of life caused by Tian Dao's interference.
For example, some fungi or viruses can undergo huge mutations and become super viruses with the slightest interference from the Heavenly Dao system.
However, other life forms did not have time to evolve corresponding antibodies, resulting in an unprecedented plague that quickly swept across the entire mountain and sea continent ecosystem.
As a result, during that period, the Primordial Continent was littered with corpses, and rotten corpses piled up like mountains.
But life is tenacious after all.
After most of the life forms died, the remaining ones eventually evolved corresponding antibodies and successfully survived the era of plague ravaged by the super virus.
And it left fragments of memory deep in the blood genes to warn future generations.
Allow future generations to evolve and respond faster when the next world plague comes!
And after every mass extinction of life, the life that survives the disaster will reproduce again.
In just tens of thousands of years, the primordial Continent will usher in a new era of prosperity for life.
Then, after tens of thousands or hundreds of thousands of years of evolution, new disasters and catastrophes will come.
It's like a great cycle of life!
Or... like the process of sowing in spring and harvesting in autumn!
And every reincarnation of life brings a huge origin of the world to the world of mountains and seas!
