Washington, September 23 (ANI): An international body of earth scientists has formally agreed to move the boundary dates for the prehistoric Quaternary age by 800,000 years.
The decision has been made by the International Commission on Stratigraphy (ICS), the authority for geological science which has acted to end decades of controversy by formally declaring when the Quaternary Period, which covers both the ice age and moment early man first started to use tools, began.
In the 18th Century, the earth's history was split into four ...
