Prehistoric history

This book deals with those distant eras that preceded the known ancient historical civilizations, beginning with the universe and the emergence of life on Earth, presenting natural fluctuations and the emergence of man, his instincts, and his material and mental production. Since this topic requires investigation and comprehension that these pages fall short of, it is praiseworthy for the author that he collected its principles, coordinated its chapters, and summarized its details, making it easy for those who seek to gain more knowledge.
