Annual Review of Genetics, 1974 The origin of life is in a sense a genetic problem, for, as H. J. Muller pointed out many years ago, the essential attribute that identifies living matter is its capacity to replicate itself and its variants (1). Because this uniquely biological property

The Grayness of the Origin of Life. [PDF]
Life (Basel), 2021 In the search for life beyond Earth, distinguishing the living from the non-living is paramount. However, this distinction is often elusive, as the origin of life is likely a stepwise evolutionary process, not a singular event. Regardless of the favored origin of life model, an inherent “grayness” blurs the theorized threshold defining life.

Origins of Life and Evolution of Biospheres, 2011 A retired west-coast (U.S.A.) business man has surprised the origin of life community by announcing a major prize for origin of life research. The $50,000 award and up to $2,000,000 in potential research funding are offered “…for the best original proposal pertaining to the study of the origin of life on Earth, including an outline of work to be ...

The Universal Evolution and the Origin of LIfe [PDF]
, 2021 The origin of life occupies a very important place in the study of the evolution. Its liminal location between life and non-life poses special challenges to researchers who study this subject. Current approaches in studying the origin and evolution of early life are reductive: they either reduce the domain of non-life to the domain of life or vice ...

Viroids and the Origin of Life. [PDF]
Int J Mol Sci, 2021 Viroids are non-coding circular RNA molecules with rod-like or branched structures. They are often ribozymes, characterized by catalytic RNA. They can perform many basic functions of life and may have played a role in evolution since the beginning of life on Earth. They can cleave, join, replicate, and undergo Darwinian evolution.

Formamide and the origin of life [PDF]
Physics of Life Reviews, 2012 The complexity of life boils down to the definition: "self-sustained chemical system capable of undergoing Darwinian evolution" (Joyce, 1994) [1]. The term "self-sustained" implies a set of chemical reactions capable of harnessing energy from the environment, using it to carry out programmed anabolic and catabolic functions.

Nature, 1904 ALTHOUGH there are good reasons for believing that the life of our world is the product of its own physical conditions, and distinct from the life of other members of the solar system, it is hardly probable that living substance can be produced otherwise than by the same conditions that produced it in the past, and one of these conditions is a vast ...
