Universities Definitions of stages of growth in childhood come from many sources. Theorists such as Jean Piaget, Lev Vygotsky, Lawrence Kohlberg, and Erik Erikson have provided ways to understand development, and recent research has provided important information regarding the nature of development. In addition, stages of childhood are defined culturally by the social institutions, customs, and laws that make up a society.
Millions of years ago, we were apes, living ape lives in Africa.
So how did we get from that to this? What set us on the path to humanity? The questions are huge. But at last, there are answers. More than 6, years ago we took that first step to separate from the apes.
We see the launching of the career that ultimately led to Homo sapiens. And 3, years ago, we see the roots of our big brain begin to take hold in a tiny creature, more like a chimp than a human. The frontier of human evolution is really being brought to this razor-sharp edge.
And we now know that for millions of years, many different human-like species lived together on the planet, until one day there was only us: Homo sapiens, the most complex, adaptable animal on Earth.

Millions of years ago, on the plains of Africa, a momentous event took place. Apes that had walked on four legs stood up and walked on two.
Eventually, this change in posture would be followed by a change in their brains. Somehow, over time, they would become us. And the fossilized bones of a child from three and a half million years ago hint to us about the beginnings of human thought. We, Homo sapiens, are the first, ever, to be alone.
So what powered our evolution? Why did we become human? Scientists are scouring the most remote parts of Africa for clues. The search for answers begins here, in the Afar, northeastern Ethiopia. Millions of years of history are brought to the surface in layers of exposed rock.
The fossil bones of animals like antelopes, elephants and pigs are abundant. But the fossils of our ancestors are extremely rare. Then, in a stroke of luck, Zeray makes the find of a lifetime, a find that illuminates our origins in a unique way. On that afternoon, we decided to survey this hillside, and the first thing that we spotted was a cheekbone of the face.
It was a face so tiny, it had to be a baby. But not a baby chimp, he could tell that from its shape.
