Cooling of the Earth in the Archaean

Chapter 8 Cooling of the Earth in the Archaean 8.1 Introduction There is still considerable controversy overthe mantle temperature during the Archaean (approx. 3.5-2.7 Gyr B.P.).

The Archaean

The Archaean time followed the Hadean. The earth continued to cool. The crust got thicker. Volcanoes continued to erupt, but not as much. The earth had land, water, and a sky filled with an atmosphere.

Archaean-Proterozoic boundary (Veizer 1983), consistent with a major increase in the concentration of 87Rb in the upper crust in late Archaean-early Proterozoic time.

All organisms can be divided among the three domains of life ...

These archaean histone proteins can form both homodimers and heterodimers but eucaryote histone proteins can form only hetereodimers of H2A and H2B, and H3 and H4 core histone protein.

Evolution of the metabolic pathways in the Archaean

2 Abstract Research for evolution has many angles. Gene analysis, amino acid comparisation are some examples. In this paper, I will look at it from the metabolic point of view.

The Isua belt of 3.8-3.7 Ga metavolcanic and metased-imentary rocks, is located 150 km north-east of Nuuk, within the Archaean gneiss complex of West Greenland.

The realms of Archaean life

"B eginnings; are apt to be shadowy" wrote Rachel Carson 1. So it is with the early record of life. In the past few years, plenty of clues have emerged, both from geological studies and inferences drawn from the molecular biology of modern organisms.
