This document summarizes the evolution of man from early primate ancestors like Propliopithecus through different hominin species like Homo erectus, Neanderthals, and Cro-Magnon man. Key transitional species discussed include Australopithecus, which had characteristics of both apes and humans, and Homo erectus, considered the first true humans. Neanderthals were an advanced primitive species that lived in Europe and West Asia until around 25,000 years ago, while Cro-Magnon man was a extinct modern human that originated around 3 million years ago.
