It must be said, the average intelligence of the Glizerians seemed to be just a tad higher than that of humans. In specific environmental circumstances, their brains evolved to be more intricate, energy-efficient, and effective.
Almost every individual possessed a keen mathematical sense and a strong capability for visual perception, making them all natural artists.
The brain of a biological entity, just like various models of CPUs and GPUs, although functionally similar, can vary in structure and frequency, resulting in varying levels of performance.
The evolution of biological entities does not have a predefined goal; it is merely for better survival, meaning the birth of intelligence has always been a mere accident. Moreover, evolution is a one-way street; it can be patched up but never started over.
Hence, whoever made fewer mistakes on this one-way street had a slightly better brain.
