    Elizabeth Palermo September 15, 2015An artist's depiction of the dual meteor strike. (Don Dixon/Erik Sturkell/University of Gothenburg) It's not altogether uncommon to hear about double rainbows, but what about a double meteor strike? It's a rare event, but researchers in Sweden recently found evidence that two meteors smacked into Earth at the same time, about 458 million years ago. Researchers from the University of Gothenburg uncovered two craters in the county of Jämtland in central Sweden. The meteors that formed the craters landed just a few miles from each other at the same moment, according to Erik Sturkell, a professor...
  • Early Earth Was Purple, Study Suggests (Go Vikes!)

    The earliest life on Earth might have been just as purple as it is green today, a scientist claims. Ancient microbes might have used a molecule other than chlorophyll to harness the Sun’s rays, one that gave the organisms a violet hue. Chlorophyll, the main photosynthetic pigment of plants, absorbs mainly blue and red wavelengths from the Sun and reflects green ones, and it is this reflected light that gives plants their leafy color. This fact puzzles some biologists because the sun transmits most of its energy in the green part of the visible spectrum. “Why would chlorophyll have this...

    Ancient_antarctic_microbes_2_2 The unusual properties of frozen water may have been the ticket that made life possible. Over the decades, several notable scientists have began to suspect that life on Earth did not evolve in a warm primordial soup, but in ice—at temperatures that few living things can now tolerate. The very laws of chemistry may have actually favored ice, says Jeffrey Bada, at the Scripps Institution of Oceanography in La Jolla, California. “We’ve been arguing for a long time,” he says, “that cold conditions make much more sense, chemically, than warm conditions.” If Bada and others are correct, it would...

    "Isn't life wonderful?" sang Alma Cogan and Les Howard in their almost forgotten 1953 hit. That same year, Stanley L. Miller raised the hopes of understanding the origin of life when on 15 May, Science published his paper on the synthesis of amino acids under conditions that simulated primitive Earth's atmosphere (1). Miller had applied an electric discharge to a mixture of CH4, NH3, H2O, and H2--believed at the time to be the atmospheric composition of early Earth. Surprisingly, the products were not a random mixture of organic molecules, but rather a relatively small number of biochemically significant compounds such...

    Washington, Oct 06: A meteorite, which crashed into Australia 40 years ago, is telling researchers new things about how life may have started on Earth, and how that almost universal protein left-handedness came to be. For more than 150 years, scientists have known that the most basic building blocks of life - chains of amino acid molecules and the proteins they form - almost always have the unusual characteristic of being overwhelmingly “left-handed.” The molecules, of course, have no hands, but they are almost all asymmetrical in a way that parallels left-handedness. This observation, first made in the 1800s by...

    Full title: Ancient bubbles in Australian rocks show early Earth's air weighed less than half today's atmosphere Air bubbles trapped in 2.7 billion-year-old Australian rock suggest the Earth's atmosphere weighed less than half of today and was much thinner than previously thought. Researchers analysed the size of air bubbles that formed at the top and bottom of lava flows along the Beasley River in Western Australia's Pilbara region almost three billion years ago and used the data to calculate the atmospheric pressure at the time. The results suggest that the air at the time exerted at most half the pressure...

    A new University of Colorado at Boulder study indicates Earth in its infancy probably had substantial quantities of hydrogen in its atmosphere, a surprising finding that may alter the way many scientists think about how life began on the planet. Published in the April 7 issue of Science Express, the online edition of Science Magazine, the study concludes traditional models estimating hydrogen escape from Earth's atmosphere several billions of years ago are flawed. The new study indicates up to 40 percent of the early atmosphere was hydrogen, implying a more favorable climate for the production of pre-biotic organic compounds like...

In 1953, Stanley L. Miller, then a graduate student of Harold C. Urey at the University of Chicago, put ammonia, methane and hydrogen — the gases believed to be in early Earth’s atmosphere — along with water in a sealed flask and applied electrical sparks to simulate the effects of lightning. A week later, amino acids, the building blocks of proteins, were generated out of the simple molecules. Enshrined in...

    The question about the origin of oceans on Earth is one of the most important questions with respect to the formation of our planet and the origin of life. The most popular theory is that water was brought by impacts of comets and asteroids. Data from the Rosetta Orbiter Spectrometer for Ion and Neutral Analysis (ROSINA) instrument aboard the European Space Agency’s Rosetta spacecraft indicate that terrestrial water did not come from comets like 67P/Churyumov-Gerasimenko.

    Evidence is mounting that the time-weathered red planet was once a warm and water-rich world. And a Mars awash with water gives rise to that globe possibly being fit for habitation in its past – and perhaps a distant dwelling for life today. As sensor-laden orbiters circle the planet, NASA’s twin Mars rovers -- Spirit and Opportunity -- have been tooling about and carrying out exhaustive ground studies for nearly a year. The Opportunity robot at Meridiani Planum, for instance, has found telltale signs that water came and went repeatedly within that stretch of Martian real estate. While that intermittent...

    Scientists have long assumed that life originated in the sea. If life did spring from salt water, that could explain why all organisms use salt. But Paul Knauth, an astrobiologist with Arizona State University, says while we always assume that life came from the ocean, this theory has never been proven. He suggests we need to consider the possibility that life originated in fresh water.The next time you reach for that bag of salty chips, think for a moment about salt and life. Humans need a certain amount of salt; it is necessary for the delivery of nutrients, the transmission...

    Given the reality of the dark spots, which soon became known as "atmospheric holes" because of their appearance in the images, there is only one explanation which has endured over all these years to present. That is, the holes are due to the shadowing of the atmospheric light by an object above the atmosphere. This object simply cannot be a stony or iron meteor because the holes are very large, tens of miles in diameter. A rock of this size would provide a disastrous impact on the Earth's surface. As it turns out, water vapor is very good at absorbing...

According to the conventional hypothesis, the earliest living cells emerged as a result of chemical evolution on our planet billions of years ago in a process called abiogenesis. The alternative possibility--that living cells or their precursors arrived from space--strikes many people as science fiction. Developments over the past decade, however, have given new credibility to the idea that Earth's biosphere could have arisen from an extraterrestrial seed. Planetary scientists have learned that early in its history our solar system could have included many worlds with liquid water,...

A study using the Herschel space telescope aimed to measure the quantity of deuterium, a rare type of hydrogen, present in the comet's water. The comet had just half the amount of deuterium seen in comets. The result, published in Nature, hints at the idea that much of the Earth's water could have initially came from cometary impacts. Just a few million years after its formation, the early Earth was rocky and dry; something must have brought the water that covers...

    Scientists have long believed that comets and, or a type of very primitive meteorite called carbonaceous chondrites were the sources of early Earth's volatile elements -- which include hydrogen, nitrogen, and carbon -- and possibly organic material, too. Understanding where these volatiles came from is crucial for determining the origins of both water and life on the planet. New research led by Carnegie's Conel Alexander focuses on frozen water that was distributed throughout much of the early Solar System, but probably not in the materials that aggregated to initially form Earth...

    While Charles Darwin’s On the Origin of Species has been described as “a grand narrative—a story of origins that would change the world”,1 ironically his book very pointedly avoided the question of the origin of life itself. This ought not be surprising. Darwin’s theory of the origin of species “by means of natural selection”2 presupposes self-reproduction, so can’t explain the origin of self-reproduction. Unfortunately, many proponents of evolution seem unaware of that. They don’t acknowledge that natural selection requires pre-existing life.

    (See all these news nuggets and more by clicking the excerpt link below): 1. BBC News: “Darwin Teaching ‘Divides Opinion’” Darwinism is a controversial topic, and many believe creation should be taught in the classroom. But why is that news? 2. ScienceDaily: “Junk DNA Mechanism that Prevents Two Species from Reproducing Discovered” Has the U.S. government finally supported creationist research? Alas, no, but the results of a National Institutes of Health study fit squarely within the young-earth creation framework. 3. PhysOrg: “Charles Darwin Really Did Have Advanced Ideas about the Origin of Life” Charles Darwin was convinced that life’s origin...

    Many people make a distinction between the origin of life and the evolution of life. In this view, biological evolution refers to the gradual development of the diversity of living things from a common ancestor, while the ultimate origin of life is a separate question. This is a legitimate point, but evolution is about much more than just biology. The evolutionary worldview is that all of physical existence, both living and non-living, arose through purely natural processes. With this broad definition of evolution, abiogenesis--the spontaneous appearance of life from non-living matter--is a necessity. If life did arise on earth by...

    Church Report ^ | October 23, 2009 | Stephen Myer, Ph.D.
    Following on the heels of his last bestseller, The God Delusion, Darwinian biologist and atheist Richard Dawkins has scored another publishing triumph. The No. 5 bestseller in the country, according to the New York Times, is Dawkins’s The Great Show on Earth: The Evidence for Evolution. You might think his success would give him the courage to face critics of his ideas in open debate. But you would be wrong. As one of the architects of the theory of intelligent design, I have formally challenged Dawkins to debate our contrasting views of evolution before the public, but his representatives have...

    Was our oldest ancestor a proton-powered rock? --snip-- The picture painted by Russell and Martin is striking indeed. The last common ancestor of all life was not a free-living cell at all, but a porous rock riddled with bubbly iron-sulphur membranes that catalysed primordial biochemical reactions...

    Discovery Institute ^ | October 6, 2009
    Seattle – Richard Dawkins, the world’s leading public spokesman for Darwinian evolution and an advocate of the “new atheism,” has refused to debate Dr. Stephen C. Meyer, a prominent advocate of intelligent design and the author of the acclaimed Signature in the Cell: DNA and the Evidence for Intelligent Design. “Richard Dawkins claims that the appearance of design in biology is an illusion and claims to have refuted the case for intelligent design,” says Dr. Meyer who received his Ph.D. in the philosophy of science from the University of Cambridge in England. “But Dawkins assiduously avoids addressing the key evidence...

    Despite “decades of persistent failure to create life by the ‘spark in the soup’ method,”[1] evolutionary biochemists are still trying to find an exclusively naturalistic explanation for how the first cell developed. Many possible chemical precursors to life have been systematically ruled out by rigorous experiments. What they have found is that the molecules necessary for life are found exclusively within cells that are already living. One explanation proposed by evolutionists...

    Chapter 12: Life Requires a Source of Information by Dr. Werner Gitt May 14, 2009 The common factor present in all living organisms, from bacteria to man, is the information contained in all their cells. It has been discovered that nowhere else can a higher statistical packing density of information (see appendix A1.2.3) be found. The information present in living systems falls in the category of “operational information” as discussed in chapter 7. This information is exactly tuned in to the infinitude of life processes and situations, and its origin can be ascribed to creative constructional information (chapter 7). The...
  • Evolutionary origin of life even more difficult

    Journal of Creation ^ | Michael J. Oard
    Evolutionary origin of life even more difficult Michael J. Oard Both evolutionists and creationists concede that the naturalistic origin of life is extremely difficult to fathom. Our understanding of life has come a long way since Stanley Miller’s simplistic exploration in 1953, which used the wrong chemicals and achieved only simple amino acids. Using what is believed to be a more realistic primitive atmosphere, little if any amino acids have been formed.[1] Since Miller’s experiment, DNA has been discovered and all the myriad machine-like components of the cell have shown the extreme complexity of even the ‘simplest’ looking life. Back...

    Ancient Oxygen-Rich Rocks Confound Evolutionary Timescale by Brian Thomas, M.S.* Many origin of life researchers have for decades argued that the early earth must have had a “reducing” atmosphere, meaning that it had very little oxygen. This argument has no direct evidence to support it other than the knowledge that oxygen destroys the delicate molecules that comprise cells today. If the first living cells evolved, they would have needed an atmosphere with little or no oxygen. But new research supports the idea that the earth’s surface was always oxygenated...

    AiG ^ | March 19, 2009 | Dr. Werner Gitt
    In the Beginning was Information: The Five Levels of the Information Concept ...Because of the philosophical bias, both information and life itself are regarded as purely material phenomena in the evolutionary view. The origin and the nature of life is reduced to physical-chemical causes. In the words of Jean B. de Lamarck (1744–1829), “Life is merely a physical phenomenon. All manifestations of life are based on mechanical, physical, and chemical causes, being properties of organic matter” (Philosophie Zoologique, Paris, 1809, Vol. 1, p. 104 f). The German evolutionist Manfred Eigen expressed a similar view [E2, p. 149]: “The logic of...

    ...Embarrassed Darwinists The next for consideration is Jonathan Wells and his Icons of Evolution. A stinging critique of ten familiar textbook evidences for evolution, Wells’ book provoked shrill cries of dismay from Darwinists, including Jerry Coyne and Eugenie Scott. Wells’ reply is highlighted as a rhetorically powerful rebuttal in which he catches his critics in scientific carelessness and in the debate tactic of ‘shifting the goalposts’. An example is the issue of embryonic homology—the Darwinian claim that embryos in various vertebrates look alike at various stages of development, and that this indicates common ancestry. Wells pointed out the extensive dissimilarities...
