“Shortly after the evolution of Homo Sapiens, the climatic conditions are very hard so that humans almost became extinct at the time,” said Professor Curtis Marean, a professor of prehistory from Arizona State University.
Experts suspect, not many humans who survive in this period. Allegations that the population is now only come from a little man who can survive based on the amount of genetic diversity in modern humans, relatively at least compared to other species.
Some researchers even claim there was a time when humans lived just a few hundred people remaining. Nevertheless, many people who doubt this theory because it is not supported by scientific evidence is quite strong.
