The evolution of primitive man was the great event of the glacial period, with the mid-mammals, ancestors of Primates and simians, playing a crucial role in the process. [1]
The mid-mammals exhibited improved traits, including disgust reactions, hoarding instincts, and a propensity for constructing elaborate shelters, setting them apart from their ancestors. [2]
Internecine battles nearly destroyed the entire species, but peace prevailed and a lone tribe of less than one hundred individuals resumed a semipeaceful existence. [3] The mid-mammals killed off the dawn mammals in a relentless war, leaving no survivors of the pre-existent ancestral race. [4] For six hundred generations, the mid-mammals terrorized and subdued their corner of creation in a world devoid of great and vicious predators. [5] The sudden appearance of mid-mammals marked a significant evolution during the glacial period, leading to the emergence of primitive man. [6]
