Theoretical , , and science popularizer, Paul Davies, has imagined a "quantum recipe" for the origin of life:

Problems with the Natural Chemical "Origin of Life" …

The Elementary Forms of the Religious Life (1912)

The enigma is the origin of so unlikely an organization of these atoms andmolecules.
The same book is also called the Lamb’s Book of Life because it contains the names of those who have been redeemed by the blood of the Lord Jesus (Revelation 13:8; 21:27).

How can you be sure your name is written in the Book of Life?

The RNA World and other origin-of-life theories. by Brig Klyce

Another kind of life, entirely different from ours, is conceivable, yes.
It becomes clear at this point that one illegitimate role of the investigatoris that of providing a portion of the configurational entropy work, i.e.,the "selecting" work portion of the total -T Scwork.

It is sometimes argued that the type of amino acid that is present in aprotein is critical only at certain positions---active sites---along thechain, but not at every position.

 

The Origin of Life - Abiogenesis by Chemical Evolution?

Davies seems to worry most about the issue of complexity of quantum life:
Evolution does not change any single individual. Instead, it changes the inherited means of growth and development that typify a population (a group of individuals of the same species living in a particular habitat). Parents pass adaptive genetic changes to their offspring, and ultimately these changes become common throughout a population. As a result, the offspring inherit those genetic characteristics that enhance their chances of survival and ability to give birth, which may work well until the environment changes. Over time, genetic change can alter a species' overall way of life, such as what it eats, how it grows, and where it can live. Human evolution took place as new genetic variations in early ancestor populations favored new abilities to adapt to environmental change and so altered the human way of life.

[6-page philosophical and historical analysis of definition of life written for Prof.
In a context, in order to discuss, much less discover, the origin of life, we must first answer the question, "What is ?" We can pose that question more coherently by asking, "What essential processes underpin the activity of living?" Knowing the fundamental universal physico-chemical processes that underpin the activity of living systems gives us a starting point for making observations, generating hypotheses, and performing experiments in the search for life’s origin — for those processes somehow must have given rise to the earliest cells, the basic building blocks and working units of all living things on Earth. We must discover the characteristics of the earliest cells from which all current living things descended.

The Origin of Life Flashcards | Quizlet

Looking back over the geologic history of the Earth, scientists have found that the early atmosphere formed first, then the oceans formed, then life came along and finally oxygen was added to the atmosphere. Here we will briefly discuss the formation of each. For a more extensive discussion of the extensive history of the Earth, consider taking an Earth Science course on the subject!

Origin of life - encyclopedia article - Citizendium

Humans are . Physical and genetic similarities show that the modern human , Homo sapiens, has a very close relationship to another group of primate species, the apes. Humans and the great apes (large apes) of Africa -- chimpanzees (including bonobos, or so-called “pygmy chimpanzees”) and gorillas -- share a common ancestor that lived between 8 and 6 million years ago. Humans first evolved in Africa, and much of human evolution occurred on that continent. The fossils of early humans who lived between 6 and 2 million years ago come entirely from Africa.

Scientists do not know the origin of life on ..

Human evolution is the lengthy process of change by which people originated from apelike ancestors. Scientific evidence shows that the physical and behavioral traits shared by all people originated from apelike ancestors and evolved over a period of approximately six million years.
