The evolution of the Egyptian tribe's bodies is actively controlled, continuously self-reflected on through trial and error.
This kind of evolution is very quick, so much so that the next generation would appear completely different in physical appearance compared to the previous one—the two would not even seem to be of the same race.
However, the drawback of this rapid evolution is that the Egyptian tribe has an upper limit.
Throughout countless years, no matter how their organic bodies evolved, their cerebral core had never changed. It could only be combined into a parallel computing large-core structure after death, and it could only change in quantity, not quality.
From the perspective of 21st-century human science, the Egyptian tribe would be classified as bionic robots.
But in the 31st century of the Ninth Timeline, humans had witnessed countless other civilizations in the universe, which radically changed their understanding of living beings and intelligent lifeforms.
