	The Evolution of Life
		The Earth's age of final formation as a planet is estimated at around 4600 million years.
		This used to be called the "Hadean Period" from 4600 - 3800 million years ago, but has recently (in 2004) been renamed Eoarchean.
		During this period the heavier molten iron sank to the middle of the newly forming Earth, to become the core.

	Palaeos Hadean: The Hadean Eon
		The Hadean has no place in the ICS system followed in the rest of Palaeos.
		The ICS lumps everything earlier than 3600 Mya into the Eoarchean Era of the Archean Eon.
		During Hadean time, the Earth and Solar System formed by coagulation and gravitational contraction from a large cloud of gas and dust around the sun, called an accretion disc.
