Origins of Life - Cambridge - The majority view is that life began with replicating molecules, the precursors of modern genes. The minority belief is that random populations of molecules evolved metabolic activities before exact replication existed. Dyson analyzes both of these theories with reference to recent important discoveries by geologists and chemists. His main aim is to stimulate experiments that could help to decide which theory is correct. This second edition covers the enormous advances that have been made in ...

Origin of life - Simple English Wikipedia, the free ... - The origin of life on Earth is a scientific problem which is not yet solved. There are many ideas, but few clear facts. Most experts agree that all life today evolved by common descent from a single primitive lifeform. It is not known how this early life form evolved, but scientists think it was a natural process which happened about 3,900 million years ago. This is in accord with the philosophy of naturalism: only natural causes are admitted. It is not known if metabolism came first or genetics

Re-conceptualizing the origins of life | Philosophical ... - The origin of life is widely regarded as one of the most important open problems in science. It is also notorious for being one of the most difficult. It is now almost 100 years since scientific efforts to solve the problem began in earnest, with the work of Oparin and Haldane . Both proposed that organic material, subjected to suitable primitive environmental conditions, could begin to increase in complexity, eventually giving rise to living cells. It was not until about 30 years ...

Origins of Life Initiative - The Origins of Life Initiative supports multi-disciplinary research aimed at revealing if life is abundant in the Universe. We seek to understand how the initial conditions on planets, including our own Earth and planets around other stars, dictated the origins of life and its subsequent evolution.

The Origin of Life | American Scientist - The essential legacy of the Primordial Soup was twofold: It simplified the notion of the origin of life to a single pivotal event, and then it proposed that that event—the step that occurred after the molecules were made—was a result of chance. In the standard language, life is to be seen, in the end, as a "frozen accident."

Overview | Origins of Life Initiative - The Origins of Life Initiative is a community of Harvard faculty, senior researchers, postdoctoral fellows, graduate students and undergraduates fascinated by the challenge of answering this question.

Origin of Life - an overview | ScienceDirect Topics - The origin of life is a long-standing and controversial subject concerned with how the first known single-cell organisms called prokaryotes probably originated in the Archean period (4-2.5 BYA) and about 3.8 BYA in the oceans when chemical composition of the ocean and the atmosphere was very different from what it is today (see Dostal et al., 2009).

Origin Of Life - - Origin of Life - Spontaneous Generation For millennia, the Origin of Life was thought to be the result of Abiogenesis (also known as "Spontaneous Generation"). The doctrine of Spontaneous Generation holds that organic life could and does arise from inorganic matter. As late as the 17th century, there were recipes to "create" life. Take sweaty rags, wrap them around wheat, and set them in an ...

Origins of building blocks of life: A review - ScienceDirect - Over time, philosophers and scientists have proposed many different theories for the origin of life. The best-known theory is the "Prebiotic soup" theory hypothesized by Oparin in 1924 (Oparin, 1957). In this theory, organic compounds were created in a reductive atmosphere from the action of sunlight and lightning.

Evolution 101: From Soup to Cells - the Origin of Life - The origin of life might seem like the ultimate cold case: no one was there to observe it and much of the relevant evidence has been lost in the intervening 3.5 billion years or so. Nonetheless, many separate lines of evidence do shed light on this event, and as biologists continue to investigate these data, they are slowly piecing together a picture of how life originated. Major lines of ...

Origin of life - - Origin-of-life researchers have battled with this problem and all sorts of potential solutions have been suggested but the problem remains unsolved. 14 Even getting 99% purity, which would require some totally artificial, unlikely mechanism for 'nature' to create, doesn't cut it. Life needs 100% pure left-handed amino acids. The reason for this is that placing a right-handed amino acid ...

Life - The origin of life | Britannica - The origin of life is a result of a supernatural event—that is, one irretrievably beyond the descriptive powers of physics, chemistry, and other science. Life, particularly simple forms, spontaneously and readily arises from nonliving matter in short periods of time, today as in the past.

Abiogenesis - Wikipedia - In evolutionary biology, abiogenesis, or informally the origin of life, is the natural process by which life has arisen from non-living matter, such as simple organic compounds. While the details of this process are still unknown, the prevailing scientific hypothesis is that the transition from non-living to living entities was not a single event, but an evolutionary process of increasing complexity that involved molecular self-replication, self-assembly, autocatalysis, and the emergence of cell
