GENERAL KNOWLEDGE

Detailed explanation-1: -Scientists are sure that Homo sapiens first evolved in Africa, and we know that every person alive today can trace their genetic ancestry to there. It has long been thought that we began in one single east or south African population, which eventually spread into Asia and Europe.

Detailed explanation-2: -Modern humans originated in Africa within the past 200, 000 years and evolved from their most likely recent common ancestor, Homo erectus, which means ‘upright man’ in Latin. Homo erectus is an extinct species of human that lived between 1.9 million and 135, 000 years ago.

Detailed explanation-3: -Though it is unclear when some modern humans first left Africa, evidence shows that these modern humans did not leave Africa until between 60, 000 and 90, 000 years ago. Most likely, a change in climate helped to push them out.
