Petteri Mussalo,Virpi Hotti,Hanna Mussaloygen have been studied intensively and extensively, but the other essential elements have been rather neglected in the studies of chemical and biological evolution. This article attempts to assess the significance of inorganic chemistry in chemical and biological evolutionary processes on the earth.

The signature of environments is written in sediments in the form of specific “biological marker” componen

Shahrokh Nikou,Malin Brännback,Gunilla Widénils occur in rocks dated at ∿ 3300 – 3200 m.y. Evidence relating to possible biogenic markers in rocks reliably dated at 3800 – 3750 m.y. is more difficult to evaluate. Much scope remains for future work.

It is an awesome reflection that the carbon in our bodies is the very carbon which was generated during the birth of a star. There is a perceptible continuum through the billions of years which can be revealed by the study of chemistry. Studies

These include:.The relationship of recent measurements relevant to light element nucleosynthesis in the big bang and the question of the expanding universe is discussed, as is the possibility of forming super-heavy elements during supernova explosions.
