Introduction - History of India
1. Introduction to History of India
1.1 The Earth
The oldest rocks which have been found so far (on the Earth) date to about 3.8 to 3.9 billion years ago (by several radiometric dating methods). Some of these rocks are sedimentary, and include minerals which are themselves as old as 4.1 to 4.2 billion years. Rocks of this age are relatively rare, however rocks that are at least 3.5 billion years in age have been found on North America, Greenland, Australia, Africa, and Asia.
1.2 The first Upright Ape
An analysis of six-million-year-old bones from an early human ancestor at lived in what is now Kenya suggests that the species was the earliest known hominine (humans and their ancestors), to walk.
"This provides really solid evidence that these fossils actually belong to an upright-walking early human ancestor," said study lead author Brian Richmond, a biological anthropologist at George Washington University in Washington, D.C.
1.3 Lucy
Lucy was found by Donald Johanson and Tom Gray on the 30th of November, 1974, at the site of Hadar in Ethiopia. After many hours of excavation, screening, and sorting, several hundred fragments of bone had been recovered, representing 40% of a single hominid skeleton.

1.4 India & Human Living
Isolated remains of Homo erectus in Hathnora in the Narmada Valley in Central India indicate that India might have been inhabited somewhere between 200,000 to 500,000 years ago. Recent finds in Tamil Nadu (at c. 75,000 years ago, before and after the explosion of the Toba volcano) indicate the presence of the first anatomically modern humans in the area.
