Macromolecules and the Origin of Life [PDF]
Origins of Life, 1974 From our knowledge of present day organisms, it is hard to imagine a living assembly, even at its most primitive stage, without macromolecules. In order to look for the macromolecules which possibly participated in the assembly of the primitive organisms, the reaction and formation of polymers in HCN under irradiation of ultraviolet ray of 184.9 nm ...

Angewandte Chemie International Edition in English, 1973
AbstractThe theory of the evolution of the species, which is today widely accepted, requires a starting point. It is postulated that the biological starting point could have emerged only if chemical evolution had preceded it. Experiments are described which show the formation of organic substances from inorganic gases under conditions which prevailed ...

Origins of Life and Evolution of Biospheres, 2005
Sea ice occurs abundantly at the polar caps of the Earth and, probably, of many other planets. Its static and dynamic properties that may be important for prebiotic and early biotic reactions are described. It concentrates substrates and has many features that are important for catalytical actions. We propose that it provided optimal conditions for the

, 2014 Biological evolution begins with the origin of life, but the subject is the perhaps the most interdisciplinary of any in science. Understanding how life began on Earth requires knowledge of the astronomical, geological, and atmospheric settings. However, those settings are in turn dependent on knowing the time period when life arose, which comes from ...

The origin of life is a large and active field of research, and one chapter in this book can hardly do it justice. Yet, if we are to make reasonable inferences about the probability of life on other worlds, we must be able to gauge the possibility that living systems could have arisen (or arrived) there in the first place. And that, in turn, depends on

Hypercycles and the origin of life
Nature, 1979Perhaps the most difficult step to explain in the origin of life is that from the replication of molecules (RNA for example) in the absence of specific proteins, to the appearance of polymerases and other proteins involved in the replication of RNA and themselves coded for by that RNA.

Origins of Life, 1977
Random chemical reactions in the Earth's primitive hydrosphere could have generated no more than 200 bits of information, whereas the first Darwinian organism must have encoded about a million bits, and therefore could not have arisen by chance. This information gap is bridged by separating reproduction from organism, and postulating a reproductive ...

The origin of life at the origin of ageing?
Ageing Research Reviews, 2017At first glance, the ageing of unicellular organisms would appear to be different from the ageing of complex, multicellular organisms. In an attempt to describe the nature of ageing in diverse organisms, the intimate links between the origins of life and ageing are examined.

Since the dawn of human civilization, man has been confronted with the mysteries of his origin and fate, and the nature of life itself. In the earliest accounts of Egyptian, Indian, Asian, and Greek cultures, we find a mixture of de facto acceptance of the continuous creation of life and some mythical description of man’s own origin (Oparin).

The question of the origin of life was probably asked as soon as humans developed self-consciousness. Our ancestors realized very early that plants, animals, and humans, are distinct from non-living entities on Earth such as rocks, water, and air. Where did life come from?
