In the south, where the rock is limestone, the vegetation is richer, and the climate milder. This area is known as the 'White Peak'.

Today's knowledge of fossil ages comes primarily from radiometric dating, also known as radioactive dating. Radiometric dating relies on the properties of isotopes. These are chemical elements, like carbon or uranium, that are identical except for one key feature -- the number of neutrons in their nucleus.

A species of apes has entered its own Stone Age period and is using tools in a way which would have been familiar to our caveman ancestors. Scientists have discovered the first evidence of a non-human species changing the way it uses instruments to process its food.

Radiometric dating Contrary to this, the absolute dating is the technique, using which the exact age of the artifacts, fossils, or sites are ascertained. The relative dating is the technique what ascertain from age of the artifacts, rocks or even sites while comparing one from the other.
