As early as seven or eight million years ago, during the era when humans were still ancient apes, and before Homo sapiens were born, the DNA sequence of humans had already been perfected and solidified.
Strictly speaking, the human race was actually born at that time.
Even if those "humans" were still covered in hair, walked on all fours, and had no mature language or writing, and the efficiency of information transfer between different individuals was not even as good as dolphins, the objective fact is that humans were born at that time.
The ancient apes did not seem to be a part of an intelligent civilization, but that was the reality.
In the millions of years that followed, both the physical shape and intelligence of humans have changed, but the underlying information in the genes has remained essentially unchanged.
