UCLA researchers: Life got started shortly after planet cooled

Life on Earth likely started 4.1 billion years ago -- much earlier than scientists thought

From Phys.org:

Life on Earth likely started 4.1 billion years ago—much earlier than scientists thought

UCLA geochemists have found evidence that life likely existed on Earth at least 4.1 billion years ago—300 million years earlier than previous research suggested. The discovery indicates that life may have begun shortly after the planet formed 4.54 billion years ago.

“Twenty years ago, this would have been heretical; finding evidence of life 3.8 billion years ago was shocking,” said Mark Harrison, co-author of the research and a professor of geochemistry at UCLA.

“The early Earth certainly wasn’t a hellish, dry, boiling planet; we see absolutely no evidence for that,” Harrison said. “The planet was probably much more like it is today than previously thought.”

Analyzing 10,000 zircons,

The scientists identified 656 zircons containing dark specks that could be revealing and closely analyzed 79 of them with Raman spectroscopy, a technique that shows the molecular and chemical structure of ancient microorganisms in three dimensions. More.

Obviously, if this find holds up—given the information load even “simple life forms require—we can rule out a strict Darwinian explanation. After all, if such an explanation were correct, rocks would be evolving into life all around us. To say nothing of Boltzmann brains. 😉

That said, sometimes these finds fall apart. Consider the case of the Australian chert find: World’s oldest “microfossils” [3.46 bya] are not life forms after all. Researchers working in the abyss of time are working with fragments. So stay tuned.

Does nature just “naturally” produce life?


Can we solve the mystery of the origin of life by creating life in the lab? (It may come to that.)

With Enceladus the toast of the solar system, here’s a wrap-up of the origin-of-life problem

Anyway, significance and abstract:

Evidence for carbon cycling or biologic activity can be derived from carbon isotopes, because a high 12C/13C ratio is characteristic of biogenic carbon due to the large isotopic fractionation associated with enzymatic carbon fixation. The earliest materials measured for carbon isotopes at 3.8 Ga are isotopically light, and thus potentially biogenic. Because Earth’s known rock record extends only to ~4 Ga, earlier periods of history are accessible only through mineral grains deposited in later sediments. We report 12C/13C of graphite preserved in 4.1-Ga zircon. Its complete encasement in crack-free, undisturbed zircon demonstrates that it is not contamination from more recent geologic processes. Its 12C-rich isotopic signature may be evidence for the origin of life on Earth by 4.1 Ga.

Abstract: Evidence of life on Earth is manifestly preserved in the rock record. However, the microfossil record only extends to ~3.5 billion years (Ga), the chemofossil record arguably to ~3.8 Ga, and the rock record to 4.0 Ga. Detrital zircons from Jack Hills, Western Australia range in age up to nearly 4.4 Ga. From a population of over 10,000 Jack Hills zircons, we identified one >3.8-Ga zircon that contains primary graphite inclusions. Here, we report carbon isotopic measurements on these inclusions in a concordant, 4.10 ± 0.01-Ga zircon. We interpret these inclusions as primary due to their enclosure in a crack-free host as shown by transmission X-ray microscopy and their crystal habit. Their d13CPDB of -24 ± 5‰ is consistent with a biogenic origin and may be evidence that a terrestrial biosphere had emerged by 4.1 Ga, or ~300 My earlier than has been previously proposed.

"If the results are correct, life is about 4.1 billion years old. That means “instant soup” only took about 300 million years. You know what they say, a watched pot never boils!"
Lol! You evodelusionists are amazing! A few months ago, when I told one other like you that there's evidence that bacteria existed more than 4 billion Darwin years ago, he couldn't tell me "you don't understand evolution" fast enough, that and rambling about how the inferred ages of the microbes were wrong. It was quite the experience! I wonder what tune he'll be singing now, hmm. As for ... life is about 4.1 billion years old. That means “instant soup” only took about 300 million years, says who? This says:
"The Earth formed under so much heat and pressure that it formed as a molten planet. For nearly the first billion years of formation (4.5 to 3.8 billion years ago) — called the Hadean Period (or hellish period) — Earth was bombarded continuously by the remnants of the dust and debris — like asteroids, meteors and comets — until it formed into a solid sphere, pulled into orbit around the sun and began to cool down. As Earth began to take solid form, it had no free oxygen in its atmosphere. It was so hot that the water droplets in its atmosphere could not settle to form surface water or ice. Its first atmosphere was also so poisonous, comprised of helium and hydrogen, that nothing would have been able to survive. ... About 4.1 billion years ago, the Earth’s surface — or crust — began to cool and stabilize, creating the solid surface with its rocky terrain. Clouds formed as the Earth began to cool, producing enormous volumes of rainwater that formed the oceans. For the next 1.3 billion years (3.8 to 2.5 billion years ago), the Archean Period, first life began to appear and the world’s landmasses began to form. Earth’s initial life forms were bacteria, which could survive in the highly toxic atmosphere that existed during this time."
Which might seem all nice and good for the typical Darwinist (missing the "began to cool" not "had already cooled. Anyways, according to this:
"The oldest known iron ores were deposited in the Precambrian period and are up to four billion years old (the Earth itself is estimated to be about 4.6 billion years old). At this very early stage in geological history, there was little or no oxygen in the atmosphere. So the very oldest banded iron formations cannot be the result of O2-dependent oxidation. In 1993, bacteria were discovered which do not need oxygen but can oxidize Fe(II) by using energy from light (anoxygenic phototrophic iron-oxidizing bacteria). ... This research not only provides the first clear evidence that microorganisms were directly involved in the deposition of Earth’s oldest iron formations; it also indicates that large populations of oxygen-producing cyanobacteria were at work in the shallow areas of the ancient oceans, while deeper water still reached by the light (the photic zone) tended to be populated by anoxyenic or micro-aerophilic iron-oxidizing bacteria which formed the iron deposits."
Which shows that you have life flourishing at >4.1 billion Darwin years ago, making me wonder whether anyone has stopped by to check on the health of the (mythical) first-cell. When did it spontaneously generate? How long did it take to "evolve" into whatever "evolved" into ... "evolved" into these newly discovered microbes ( assuming they did exist) and iron oxidizing bacteria??? :-/ Are you sure <300 million years (which puts it within the time where the water would be more steam than water) is enough for the poison in the soup bowl to vanish,and the spontaneously generated molecules to spontaneously form the mythical first-cell (without, of course, the help of natural selection as prebiotic NS is contradictory) for no reason whatsoever? The story is starting to look more really absurd. Kidding! It was never not absurd, it always comes down to "older/faster/younger/slower than previously thought". I bet this is all because "you don't understand evolution", right? :D Vy
And this beyond space and time, 'non-local', quantum entanglement/information is now found in every DNA and protein molecule:
Classical and Quantum Information in DNA – Elisabeth Rieper – video (Longitudinal Quantum Information along the entire length of DNA discussed at the 19:30 minute mark; at 24:00 minute mark Dr Rieper remarks that practically the whole DNA molecule can be viewed as quantum information with classical information embedded within it) https://youtu.be/2nqHOnVTxJE?t=1176 Classical and Quantum Information Channels in Protein Chain - Dj. Koruga, A. Tomi?, Z. Ratkaj, L. Matija - 2006 Abstract: Investigation of the properties of peptide plane in protein chain from both classical and quantum approach is presented. We calculated interatomic force constants for peptide plane and hydrogen bonds between peptide planes in protein chain. On the basis of force constants, displacements of each atom in peptide plane, and time of action we found that the value of the peptide plane action is close to the Planck constant. This indicates that peptide plane from the energy viewpoint possesses synergetic classical/quantum properties. Consideration of peptide planes in protein chain from information viewpoint also shows that protein chain possesses classical and quantum properties. So, it appears that protein chain behaves as a triple dual system: (1) structural - amino acids and peptide planes, (2) energy - classical and quantum state, and (3) information - classical and quantum coding. Based on experimental facts of protein chain, we proposed from the structure-energy-information viewpoint its synergetic code system. http://www.scientific.net/MSF.518.491 Quantum coherent-like state observed in a biological protein for the first time - October 13, 2015 Excerpt: If you take certain atoms and make them almost as cold as they possibly can be, the atoms will fuse into a collective low-energy quantum state called a Bose-Einstein condensate. In 1968 physicist Herbert Fröhlich predicted that a similar process at a much higher temperature could concentrate all of the vibrational energy in a biological protein into its lowest-frequency vibrational mode. Now scientists in Sweden and Germany have the first experimental evidence of such so-called Fröhlich condensation (in proteins).,,, The real-world support for Fröhlich's theory (for proteins) took so long to obtain because of the technical challenges of the experiment, Katona said. http://phys.org/news/2015-10-quantum-coherent-like-state-biological-protein.html
To say that quantum non-locality being found on such a massive scale in molecular biology is merely a 'minor' problem for Darwinism, as I have been doing in this post, is a gross understatement on my part. The fact of the matter is that, as far as empirical science is concerned, neo-Darwinism, as far as it is reliant on materialistic/naturalistic, i.e. atheistic, assumptions, is unquestionably falsified as a theory of science. Whereas the Theist is doing quite well as far as the scientific evidence is concerned since the Theist has, in fact, posited a beyond space and time cause for life all along. Verse and Music:
John 1:1-4 In the beginning was the Word, and the Word was with God, and the Word was God. He was in the beginning with God. All things were made through Him, and without Him nothing was made that was made. In Him was life, and the life was the light of men.

As briefly pointed out in post 2, although the origin of photosynthesis so early on earth is certainly not a 'minor' problem for naturalists:
Scientists unlock some key secrets of photosynthesis - July 2, 2012 Excerpt: "The photosynthetic system,, is nature's most elaborate nanoscale biological machine," said Lakshmi. "It converts light energy at unrivaled efficiency of more than 95 percent compared to 10 to 15 percent in the current man-made solar technologies.,, "Photosystem II is the engine of life," Lakshmi said. "It performs one of the most energetically demanding reactions known to mankind, splitting water, with remarkable ease and efficiency.",,, "Water is a very stable molecule and it takes four photons of light to split water," she said. "This is a challenge for chemists and physicists around the world (to imitate) as the four-photon reaction has very stringent requirements." http://phys.org/news/2012-07-scientists-key-secrets-photosynthesis.html Femtosecond snapshots of photosynthetic water oxidation - July 9, 2014 Excerpt: researchers with the Lawrence Berkeley National Laboratory (Berkeley Lab) and the SLAC National Accelerator Laboratory. Working at SLAC's Linac Coherent Light Source (LCLS), the world's most powerful x-ray laser, the researchers were able to take detailed "snapshots" of the four photon-step cycle for water oxidation in photosystem II, a large protein complex in green plants. Photosystem II is the only known biological system able to harness sunlight for the oxidation of water into molecular oxygen.,,, "Knowing how this happens is important for understanding the design principles used in natural photosynthesis," Yachandra says. http://www.sciencedaily.com/releases/2014/07/140709140254.htm Enzymes and protein complexes needed in photosynthesis – with graphs http://elshamah.heavenforum.org/t1637-enzymes-and-protein-complexes-needed-in-photosynthesis#2527 Evolutionary biology: Out of thin air John F. Allen & William Martin: Excerpt: The measure of the problem is here: “Oxygenetic photosynthesis involves about 100 proteins that are highly ordered within the photosynthetic membranes of the cell.” http://www.nature.com/nature/journal/v445/n7128/full/445610a.html
Although the origin of photosynthesis so early on earth is certainly not a 'minor' problem for naturalists/materialists, I would like to point out another 'minor' problem for naturalists. Recently it has been found that photosynthesis uses quantum coherence in order to achieve such amazing energy efficiency as is displayed in photosynthesis:
Uncovering Quantum Secret in Photosynthesis - June 20, 2013 Excerpt: Photosynthetic organisms, such as plants and some bacteria, have mastered this process: In less than a couple of trillionths of a second, 95 percent of the sunlight they absorb is whisked away to drive the metabolic reactions that provide them with energy. The efficiency of photovoltaic cells currently on the market is around 20 percent.,,, Van Hulst and his group have evaluated the energy transport pathways of separate individual but chemically identical, antenna proteins, and have shown that each protein uses a distinct pathway. The most surprising discovery was that the transport paths within single proteins can vary over time due to changes in the environmental conditions, apparently adapting for optimal efficiency. "These results show that coherence, a genuine quantum effect of superposition of states, is responsible for maintaining high levels of transport efficiency in biological systems, even while they adapt their energy transport pathways due to environmental influences" says van Hulst. http://www.sciencedaily.com/releases/2013/06/130620142932.htm
The problem that quantum coherence presents for naturalists/materialists is that coherence is a 'non-local' effect:
Coherence and nonlocality Usually quantum nonlocality is discussed in terms of correlated multiparticle systems such as those discussed by John Bell in his famous 1964 theorem and then later clarified by GHZ, David Mermin and others. But more striking and significant is the qualitative nonlocal phenomena associated with coherent states,,,, In fact, theoretically these two kinds of nonlocality have precisely the same basis: the unmeasured singlet state uncovered by EPR is a coherent 'pure state' despite its spacial extension, and when the parts are realized in a measurement (a la Bell) this coherence is harvested or cashed in. Whereas the "EPR" connections are ephemeral and fragile, some forms of nonlocal coherence are robust. http://www.nonlocal.com/hbar/nonlocalcoherence.html
The 'minor' problem that quantum non-locality presents to materialistic explanations is that one cannot appeal to a within space-time materialistic cause in order to explain the effect of quantum non-locality, but one is forced to appeal to a beyond space and time cause in order to explain quantum non-locality.
Looking beyond space and time to cope with quantum theory – 29 October 2012 Excerpt: “Our result gives weight to the idea that quantum correlations somehow arise from outside spacetime, in the sense that no story in space and time can describe them,” http://www.quantumlah.org/highlight/121029_hidden_influences.php
Moreover, the 'minor', non-local, problem for materialists/naturalists goes much deeper than merely photosynthesis. In fact, it is now found that quantum non-locality is in every DNA and protein molecule. In learning this, first it is important to learn that ‘non-local’, beyond space and time, quantum entanglement (A. Aspect, A. Zeilinger, etc..) can be used as a ‘quantum information channel’,,,
Quantum Entanglement and Information Quantum entanglement is a physical resource, like energy, associated with the peculiar nonclassical correlations that are possible between separated quantum systems. Entanglement can be measured, transformed, and purified. A pair of quantum systems in an entangled state can be used as a quantum information channel to perform computational and cryptographic tasks that are impossible for classical systems. The general study of the information-processing capabilities of quantum systems is the subject of quantum information theory. http://plato.stanford.edu/entries/qt-entangle/
Zachriel, "That means “instant soup” only took about 300 million years." Hmmm, a week ago it was 600 million years. The time available has been cut in half. However, we still have to fit the cooling of the "just formed earth", presumably an unimaginably hot place, into the mix. Not many millennia left. Don't worry, your theory is in good hands. Denial is a powerful force. bFast
Who was "watching the pot" Zachriel? And 300 million (probably less than that) is undeniable fast per scientific consensus - "instant soup" is a better description sorry, ppolish
ppolish: So instead of “primordial soup” we have “instant soup” The Earth's crust formed about 4.4 billion years ago, shortly followed by an atmosphere and oceans. If the results are correct, life is about 4.1 billion years old. That means "instant soup" only took about 300 million years. You know what they say, a watched pot never boils! Zachriel
So instead of "primordial soup" we have "instant soup", Yes, science has a lot of "rethinking" to do. ppolish

Moreover, entire 'microbial ecosystems' are now found to go back at least 3.5 billion years
3.5 billion-year-old ecosystem found - November 12, 2013 Excerpt: "Mound-like deposits created by ancient bacteria, called stromatolites, and microfossils of bacteria have previously been discovered in this region. However, a phenomenon called microbially induced sedimentary structures, or MISS, had not previously been seen in rocks of this great age." MISS were created by microbial mats as the microbial communities responded to changes in physical sediment dynamics, Professor Wacey said. "A common example would be the binding together of sediment grains by microbes to prevent their erosion by water currents," he said. "The significance of MISS is that they not only demonstrate the presence of life, but also the presence of whole microbial ecosystems that could co-ordinate with one another to respond to changes in their environment.",,, The team described the various MISS from the ancient coastal flats preserved in the Dresser Formation and found close similarities in both form and preservation style to MISS in younger rocks. http://www.sciencealert.com.au/news/20131211-25003.html Geobiologist Noffke Reports Signs of Life that Are 3.48 Billion Years Old - 11/11/13 Excerpt: the mats woven of tiny microbes we see today covering tidal flats were also present as life was beginning on Earth. The mats, which are colonies of cyanobacteria, can cause unusual textures and formations in the sand beneath them. Noffke has identified 17 main groups of such textures caused by present-day microbial mats, and has found corresponding structures in geological formations dating back through the ages. http://www.odu.edu/about/odu-publications/insideodu/2013/11/11/topstory1 Microbial Mat Ecology – Image on page 92 (third page down) http://www.dsls.usra.edu/biologycourse/workbook/Unit2.2.pdf
,,,Please note, that if even one type of bacteria group did not exist in this complex cycle of biogeochemical interdependence, that was illustrated on the third page of the preceding site, then all of the different bacteria would soon die out. This essential biogeochemical interdependence, of the most primitive different types of bacteria that we have evidence of on ancient earth, makes the origin of life ‘problem’ for neo-Darwinists that much worse. For now not only do neo-Darwinists have to explain how the ‘miracle of life’ happened once with the origin of photosynthetic bacteria, but they must now also explain how all these different types bacteria, that photosynthetic bacteria are dependent on, in this irreducibly complex biogeochemical web, miraculously arose just in time to supply the necessary nutrients, in their biogeochemical link in the chain, for photosynthetic bacteria to continue to survive. As well, though not clearly illustrated in the illustration on the preceding site, please note that a long term tectonic cycle, of the turnover the Earth’s crustal rocks, must also be fine-tuned to a certain degree with the bacteria and thus plays an important ‘foundational’ role in the overall ecology of the biogeochemical system that must be accounted for as well. This following study gives strong indication that the long term tectonic cycle of the entire earth and early bacterial life indeed worked in conjunction with each other:
Ancient Earth Crust Stored in Deep Mantle - Apr. 24, 2013 Excerpt: New research,, demonstrates that oceanic volcanic rocks contain samples of recycled crust dating back to the Archean era 2.5 billion years ago.,, This indicates that the sulfur comes from a deep mantle reservoir containing crustal material subducted before the Great Oxidation Event and preserved for over half the age of Earth.

Dr. Ross points out that the extremely long amount of time it took to prepare a suitable place for humans to exist in this universe, for the relatively short period of time that we can exist on this planet, is actually a point of evidence that argues strongly for Theism:
Anthropic Principle: A Precise Plan for Humanity By Hugh Ross Excerpt: Brandon Carter, the British mathematician who coined the term “anthropic principle” (1974), noted the strange inequity of a universe that spends about 15 billion years “preparing” for the existence of a creature that has the potential to survive no more than 10 million years (optimistically).,, Carter and (later) astrophysicists John Barrow and Frank Tipler demonstrated that the inequality exists for virtually any conceivable intelligent species under any conceivable life-support conditions. Roughly 15 billion years represents a minimum preparation time for advanced life: 11 billion toward formation of a stable planetary system, one with the right chemical and physical conditions for primitive life, and four billion more years toward preparation of a planet within that system, one richly layered with the biodeposits necessary for civilized intelligent life. Even this long time and convergence of “just right” conditions reflect miraculous efficiency. Moreover the physical and biological conditions necessary to support an intelligent civilized species do not last indefinitely. They are subject to continuous change: the Sun continues to brighten, Earth’s rotation period lengthens, Earth’s plate tectonic activity declines, and Earth’s atmospheric composition varies. In just 10 million years or less, Earth will lose its ability to sustain human life. In fact, this estimate of the human habitability time window may be grossly optimistic. In all likelihood, a nearby supernova eruption, a climatic perturbation, a social or environmental upheaval, or the genetic accumulation of negative mutations will doom the species to extinction sometime sooner than twenty thousand years from now. http://christiangodblog.blogspot.com/2006_12_01_archive.html
Isaiah 45:18-19 For thus says the Lord, who created the heavens, who is God, who formed the earth and made it, who established it, who did not create it in vain, who formed it to be inhabited: “I am the Lord, and there is no other. I have not spoken in secret, in a dark place of the earth; I did not say to the seed of Jacob, ‘seek me in vain’; I, the Lord speak righteousness, I declare things that are right.”

Although this finding pushes the OOL back even earlier than thought, making what was already a bad situation even worse for naturalists, the extremely early origin of life on earth was already confirmed by several different lines of evidence other than the discredited 3.46 bya chert microfossils.

These deposits display an enrichment of the carbon-12 isotope. Other chemical signatures from these formations that have been interpreted as biological remnants include uranium/thorium fractionation and banded iron formations. Recently, a team from Australia argued that the dolomite in these formations also reflects biological activity, specifically that of sulfate-reducing bacteria. http://www.reasons.org/when-did-life-first-appear-earth "We get that evidence from looking at carbon 12 to carbon 13 analysis. And it tells us that in Earth's oldest (sedimentary) rock, which dates at 3.80 billion years ago, we find an abundance for the carbon signature of living systems. Namely, that life prefers carbon 12. And so if you see a higher ratio of carbon 12 to carbon 13 that means that carbon has been processed by life. And it is that kind of evidence that tells us that life has been abundant on earth as far back as 3.80 billion years ago (when water was first present on earth).,,, And that same carbon 12 to carbon 13 analysis tells us that planet earth, over it entire 4.5662 billion year history has never had prebiotics. Prebiotics would have a higher ratio of carbon 13 to carbon 12. All the carbonaceous material, we see in the entire geological record of the earth, has the signature of being post-biotic not pre-biotic. Which means planet earth never had a primordial soup.
