The origin of life occurred only once on Earth.8.

In attempting to answer a question about the nature of the world, a scientist will form a hypothesis (or a guess) regarding the question's answer. Experiments, data gathering and study will then help the scientist to reach a conclusion.

The third, and most common hypothesis in the scientific community, is that life began approximately 3.5 billion years ago as the result of a complex sequence of chemical reactions that took place spontaneously in Earth's atmosphere.

Second, they wished to set out their model of the origin of life.

There are at least three types of hypotheses which attempt to explain the origin of life on Earth.

Every old objection raised by Thaxton, Bradley, and Olsen is recycled by Rana and Ross — from the idea that the second law of thermodynamics prohibits life to the claim that there is no explanation for chiral biomolecules, there is nothing new.

The origin-of-life model offered by Rana and Ross fails on two grounds.

Efforts are under way to find, as well as to theoretically predict, the minimal complexity of a living organism, and these results will also inform origin-of-life research.

One of the frustrations reviewing a book one finds fault with is suppressing the desire to mention all its errors, or worse attempting to correct them.

Is this "proof" of a supernatural origin of life?

Life originated in and persisted through the hostile conditions of early Earth.3.

Second, they have offered a caricature of origin-of-life research in their so-called "naturalistic predictions." The greatest difference of course is that science never appeals to divine intervention to do the heavy lifting.

Do we know how life originated on earth?

The scientific conception of life has always entailed complexity, and Rana and Ross's argument cannot be evaluated without some anchor to make it meaningful.

What is the autotrophic hypothesis of the origin of life?

All this before the end of chapter 1.

More importantly, the "RTB Model" predictions offered by Rana and Ross are not and cannot be differentiated from the predictions of modern origin-of-life research when they are testable at all.

Answer to What is the autotrophic hypothesis of the origin of life?

The creationists' current favorite scientists to quote-mine on the origin of life are Robert Shapiro (a creationist's favorite since his 1986 book), Peter Ward (paydirt from the 2000 book co-written with Donald Brownlee), and Hubert Yockey (possibly the mother lode, with half a dozen citations).

Haldane view of the origin of life

The situation was not improved when I reached the "predictions" Rana and Ross claimed are the logical scientific consequences of origin-of-life research.

The heterotrophic origin of life proposed by A

In their chapter, "Information and the Origin of Life" (p 173-210), Bradley and Thaxton introduce the notion that "design detection" was similar to archaeology, the search for extraterrestrial intelligence (SETI) particularly as depicted in Carl Sagan's fiction, and forensic investigations.

in his view the origin of life on earth

This does considerable violence to actual origin-of-life research and theory, which offer specific hypotheses about how such biomolecules formed and outlines cumulative sequences, rather than proposing life simply "condenses".

The third claim, that a rich chemistry existed under early earth conditions, is harmless enough until Rana and Ross piggyback the false assertions of their fourth prediction: The claims that modern origin-of-life researchers imagine a "placid" early environment for "long periods of time" and that such an environment would be favorable for the origin of life are unfounded.
