Do we know, from where we are? Let us come to know that we are from the species of “Homo sapiens”.
Human Evolution and Migration
Great Apes are known as the Orangutans, gorillas, chimpanzees, and humans. From these; genetically closest to the human is, the chimpanzee.
“Hominins'' is considered as the human being’s ancestor. Hominins evolution has progressed from Africa, from there they moved to the rest of the world 7 to 5 million years ago. The Skeleton of Skeletons and bones of Australopithecus who is one of the earliest human species had been discovered in many places in The Great Rift Valley of Africa.
It is a series of adjoining geographic trenches which runs close to 6400 kms. The Great Rift Valley runs from the northern part of Syria to Central Mozambique in East Africa. It can be viewed from space.

Our ancestors are classified into different species based on the physical characteristics.
Hominids - refers to human and all the modern and extinct species of Apes.
Hominins: a zoological tribe close relative to our ancestor and their sister species including the present state of the humans known as Homo sapiens, and the extinct members of Homo neanderthalensis, Homo erectus, Homo habilis and various species of Australopithecines. Among this tribe’s list, the only living species is ‘Human’. They have large brains, stand upright, walking with two legs. Few of them were able to communicate with each other and the used Microliths.
Homo habilis: the oldest human ancestor lived in Africa before 26 lakh years. They were also known as “Handy Human” and among the other tribes they were the first one who made stone tools.
Homo erectus/ergaster: 20 lakh years ago this species came into existence. They made the hand axes between 20 and 10 lakh years ago. They started to spread across the continents of Asia and Africa.
Homo sapiens known as the wise man, anatomically ‘Modern Human’, around 3 lakh years ago lived in Africa. Later on around 60 thousand years ago, they moved away from Africa and started to settle down in different parts of the earth.
