When It Comes to Explanations for the Origin of Life, Genesis Has the Quality; So, Science Comes At You With Quantity

Genesis 1
In the beginning God created the heavens and the earth.

“The origins of life on Earth bristle with puzzle and paradox. Which came first, the proteins of living cells or the genetic information that makes them? How could the metabolism of living things get started without an enclosing membrane to keep all the necessary chemicals together? But if life started inside a cell membrane, how did the necessary nutrients get in?

The questions may seem moot, since life did start somehow.” New Glimpses of Life’s Puzzling Origins…NYT June 15 2009 Article

Revolutionary New Theory For Origins Of Life On Earth

ScienceDaily (Dec. 4, 2002) — “A totally new and highly controversial theory on the origin of life on earth, is set to cause a storm in the science world and has implications for the existence of life on other planets. Research* by Professor William Martin of the University of Dusseldorf and Dr Michael Russell of the Scottish Environmental Research Centre in Glasgow, claims that living systems originated from inorganic incubators – small compartments in iron sulphide rocks. The new theory radically departs from existing perceptions of how life developed and it will be published in Philosophical Transactions B, a learned journal produced by the Royal Society”…Article Source

“According to a new study, scientists found that life on earth went from single cells to blue whales and giant sequoias in 3.5 billion years in two distinct bursts. The study was published in the Proceedings of the National Academy of Sciences. This theory is against the preconceived notion of life slowly evolved from simple to complex multicelled organism. The analysis of the fossils showed that the study of the two sized jumps were from bacteria to eukaryotic cells and from unicellular to multicellular organism.” Article

“Mineral cells might have incubated first living things.John Whitfield

Life on Earth may have begun in rocks on the ocean floor. More than 4 billion years ago, tiny cavities in minerals may have served as the first cells, two biologists are proposing. Other researchers argue that the idea leaves many questions unanswered.

The key to the new theory is iron sulphide. Hot springs deposit a honeycomb of this mineral on the ocean floor, with pockets a few hundredths of a millimetre across. This would have been the ideal place for life to get going, say William Martin, of Heinrich-Heine University in Dusseldorf, Germany, and Michael Russell of the Scottish Universities Environmental Research Centre in Glasgow, UK.

“There are lots of theories [of the origin of life] but ours is the first to start with the cell,” says Martin. Most scientists assume that self-replicating molecules or proteins came first. NatureNews Article

Methane-Belching Bugs Inspire a New Theory of the Origin of Life on Earth

Two laboratories at Penn State set out to show how an obscure undersea microbe metabolizes carbon monoxide into methane and vinegar. What they found was not merely a previously unknown biochemical process–their discovery also became the inspiration for a fundamental new theory of the origin of life on Earth, reconciling a long-contentious pair of prevailing theories. This new, “thermodynamic” theory of evolution improves upon both previous theories by proposing a central role for energy conservation during early evolution, based on a simple three-step biochemical mechanism.

New theory fills in the gap before Darwin
By Tim Friend, USA TODAY

“Forget what you learned in biology about the origin of life: that it began with a single mother of all cells and became increasingly complex. It was a simplistic notion anyway.

A new theory by leading evolutionary microbiologist Carl Woese, which may revolutionize notions on the origin of life, suggests that life really began with at least three primitive cell-like structures engaged in a promiscuous gene-swapping free-for-all more than 3 billion years ago.” USA Today Article
