The book is all about the living beings. All living beings, including
humans have originated and
evolved from the Last Universal Common Ancestor: LUCA that was possible
as a result of
spontaneous step-by-step chemical origin in about 3.750 billion years
ago from the elements
consisting of life body, such as nitrogen bases (adenine, thyamine,
cytosine, guanine, and uracil, which are made up off the elements - C,
H, O, N) and ribose sugar.
This life originated in the sediments of the palaeo floodplains at the
palaeo mouths of fresh water flows/rivers on the Hadean surface in the
Archaean Eon. This was a global phenomenon. The life on the rocky planet
like our Earth was possible because of existence of fresh water bodies
over minerals, metals, and clay deposits, which rested on Hadean surface
and active geological processes and active environments.
The book also makes an attempt to explain as to how do the simple
elements, like C, H, O, N, S,
and P first change to simple chemistry - H 2 O, NH 3 followed by CH 4
HCN, and monomers -
monosaccharides, amino acids, glycerol's/fatty acids, nucleotides, and
polymers - carbohydrates, proteins, lipids, and nucleic acids. There was
not much development for about 3210 million years (from 3750 million
years to 540 million years) and suddenly changed/jumped to complex life
forms in about 541 million years ago. Here the life originated and
evolved without head and heart from 3750 million years ago to 522
million years ago, i.e., for about 3228 million years. The head was
originated and evolved in about 521million years ago.
However, consciousness emerged along with bonding of carbon with
hydrogen and other elements which were finally converted into
nucleosides having nitrogenous base and ribose sugar. The gravity and
gravitational force intertwined with electromagnetic force were the
reason there were bonding of carbon and hydrogen and other elements to
originate and evolve LUCA, which stayed away from thermodynamic
equilibrium.
