Small Gods - More Magnificance Of The Real Universe Revealed,


The Running Chicken Nebula comprises several clouds, the most prominent of which are labelled in this vast image from the VLT Survey Telescope (VST), hosted at ESO’s Paranal site. The bright star labelled Lambda Centauri is actually much closer to us than the nebula itself, and can be seen with the naked eye. The clouds shown in wispy pink plumes are full of gas and dust, illuminated by the young and hot stars within them. Overall, this image spans an area in the sky of about 25 full Moons, one of which is shown to scale for reference.

Astronomers using the European Southern Observatory in Chile have revealed in unprecedented detail, the so-called, 'Running Chicken' nebula, named not after creationists when asked a direct question, but because some people think it resembles a running chicken. The photographs were taken using the Very Large Telescope (VLT) as a series of images capturing different wavelengths of light, then carefully stitched together to form this detailed composite image.

The Running Chicken Nebula actually comprises several regions, all of which we can see in this vast image that spans an area in the sky of about 25 full Moons [1]. The brightest region within the nebula is called IC 2948, where some people see the chicken’s head and others its rear end. The wispy pastel contours are ethereal plumes of gas and dust. Towards the centre of the image, marked by the bright, vertical, almost pillar-like, structure, is IC 2944. The brightest twinkle in this particular region is Lambda Centauri, a star visible to the naked eye that is much closer to us than the nebula itself.

There are, however, many young stars within IC 2948 and IC 2944 themselves — and while they might be bright, they’re most certainly not merry. As they spit out vast amounts of radiation, they carve up their environment much like, well, a chicken. Some regions of the nebula, known as Bok globules, can withstand the fierce bombardment from the ultraviolet radiation pervading this region. If you zoom in to the image, you might see them: small, dark, and dense pockets of dust and gas dotted across the nebula.

Other regions pictured here include, to the upper right, Gum 39 and 40, and to the lower right, Gum 41. Aside from nebulae, there are countless orange, white and blue stars, like fireworks in the sky. Overall in this image, there are more wonders than can be described — zoom in and pan across, and you’ll have a feast for the eyes.

This image is a large mosaic comprising hundreds of separate frames carefully stitched together. The individual images were taken through filters that let through light of different colours, which were then combined into the final result presented here. The observations were conducted with the wide-field camera OmegaCAM on the VST, a telescope owned by the National Institute for Astrophysics in Italy (INAF) and hosted by ESO at its Paranal site in Chile’s Atacama Desert that is ideally suited for mapping the southern sky in visible light. The data that went into making this mosaic were taken as part of the VST Photometric Hα Survey of the Southern Galactic Plane and Bulge (VPHAS+), a project aimed at better understanding the life cycle of stars.

Contrast this small fraction of the visible universe (it occupies an area of the night sky about the size of 25 full moons) with the laughably naïve description of the Universe in Genesis 1: 6-18:
And God said, Let there be a firmament in the midst of the waters, and let it divide the waters from the waters. And God made the firmament, and divided the waters which were under the firmament from the waters which were above the firmament: and it was so. And God called the firmament Heaven. And the evening and the morning were the second day.

And God said, Let the waters under the heaven be gathered together unto one place, and let the dry land appear: and it was so. And God called the dry land Earth; and the gathering together of the waters called he Seas: and God saw that it was good. And God said, Let the earth bring forth grass, the herb yielding seed, and the fruit tree yielding fruit after his kind, whose seed is in itself, upon the earth: and it was so. And the earth brought forth grass, and herb yielding seed after his kind, and the tree yielding fruit, whose seed was in itself, after his kind: and God saw that it was good. And the evening and the morning were the third day.

And God said, Let there be lights in the firmament of the heaven to divide the day from the night; and let them be for signs, and for seasons, and for days, and years: And let them be for lights in the firmament of the heaven to give light upon the earth: and it was so. And God made two great lights; the greater light to rule the day, and the lesser light to rule the night: he made the stars also. And God set them in the firmament of the heaven to give light upon the earth. And to rule over the day and over the night, and to divide the light from the darkness: and God saw that it was good. And the evening and the morning were the fourth day.

Malevolent Designer News - How Does Killing Millions of Seabirds Punish Humans For Adam's & Eve's 'Sin'?


Emperor penguins and southern elephant seals on South Georgia.
Both species at risk from avian flu.
Avian influenza has killed millions of seabirds around the world: Antarctica could be next

Avian flu is currently devastating flocks of seabirds, wiping out breeding colonies and even spreading to mammalian species such as sea lions and the southern elephant seal, the mass deaths of which are believed to have been caused by the H5N1 strain of the influenza virus.

Creationists claim that pathological parasites like the influenza viruses are the result of Adam's & Eve's sin which their beloved god inflicted on the world without prior warning in a tyrannical act of mass punishment for an arbitrary 'wrong', designated as such without any logical reason and applied to a couple of people who weren't equipped to know right from wrong and who hadn't been made aware of the real consequences.

But how killing millions of seabirds, elephant seals and other species punishes mankind or why the entire creation is being punished for a human 'crime' is never explained, leaving creationists to perform the most contorted mental gymnastics and denial of basic logic to simultaneously ascribe this to their putative designer god and make excuses to absolve it of blame for its criminal behaviour, for fear it'll come after then for not loving it enough.

Enough of the childish superstition and now for the real-world science:

Malevolent Designer News - How Creationism's Favourite Sadist Designed Ebola to Sneak Past Our Defences


Scientists discover new method Ebola virus uses to infect cells - Texas Biomed

Ebola virus.
Creationism's favourite malevolence is nothing if not sneaky in the way it designs its pathogens to make us sick and die by getting around the immune system it repeatedly designed to protect us from the pathogens it designed to make us sic and die.

For example, as researchers from the Texas Biomedical Research Institute (Texas Biomed) have discovered, the nasty little ebola virus uses a sneaky back-door approach to pass from cell to cell in a way which keeps it hidden from our immune system. Instead, it usurps the system our cells use to pass substances like proteins, nutrients and RNA from one cell to another via a network of nanotubes.

Creationism In Crisis - How We Have Evolved To Understand What Other Primates Are Saying

One of the things that creationist frauds hate is the evidence of common descent in the form of redundant structures that now serve little or no function, but which were present in an ancient ancestor. Their problem with them is that they are evidence of common ancestry and make no sense as the work of an intelligent designer. What rational designer includes details and complications that have no function?

For example, humans and many herbivores such as rhinoceroses still have the enzymes for digesting the chitin exoskeleton of insects and other arthropods, even though they never eat them. However, the ancestral stem mammal was an insectivore, but there has been no selection pressure to remove the mechanism for digesting them as the herbivores evolved, so this retention is like a fossil, showing evidence of common ancestry.

Another example is the tendency for the hairs on our neck (and back, arms and shoulders if we have any hair there) to stand up when we are startled as an automatic part of the fight or flight response and a remnant of when making yourself look bigger was a benefit to a hairy ape suddenly surprised by a potential predator.

Now scientists at the University of Geneva, Switzerland, have discovered another largely redundant ability that only makes sense as something retained from an ancient primate ancestor which is present in modern primates where it still has a useful function, and in humans where its function is redundant for all practical purposes; humans subconsciously recognise the vocalisations of other primates.

This is just another in the list of redundant structures that are evidence of evolution and common ancestry:

Unintelligent Design - How Creationism's Intelligent [Sic] Designer Stupidly Competes With Itself In An Arms Race.


Oral Herpes simplex
How the Immune System Fights to Keep Herpes at Bay | Harvard Medical School

Throughout the Cold War, starting soon after World War II and continuing through most of the second half of the 20th Century, the world's great powers, led by America on one side and Russia on the other, competed in a wasteful arms race where one side tried to outdo the other by building more powerful bombs and better delivery systems while also building better defences capable of preventing successful attack by the other. Money and resources that went into this ultimately pointless arms race could have been used for better, more peaceful projects like better world health care, better education or ending poverty and famine, yet neither side could afford to do the sensible thing because neither side trusted the other to abandon the race and compete with peace instead.

Although we can understand the pressures and insecurities that caused these wasteful arms races, we can also see the ultimate futility of it all and how the costs escalate with every turn of the spiral.

But how much more stupid would it have been if both 'sides' had the same people running them - if both America and Russia had the same political and military leaders? In other words, if the arms race was being run by one side alone, for no better reason than that the leaders had amnesia and didn't know why they built a bigger bomb or a better defence system yesterday and woke up today faced with a threat they had designed yesterday and needed to spend today designing ways to cope with these new threats?

One might be tempted to call into question the sanity of these leaders and wonder about their fitness to lead. What on Earth had allowed them to behave so stupidly? And for what reason? It certainly would have had nothing to do with the health and welfare or safety of the populations of Russia or America, or indeed the rest of the world, so could not be excused as some sort of well-intentioned altruism. An OCD or sheer malevolence, maybe, but not benevolence.

And yet creationists worship what they believe is a supernatural entity who behaves exactly like the amnesiac maniac I've just described. The natural world it reputedly designed, according to creationists, is full of example of these pointless and wasteful arms races for no ultimate long-term benefit to either 'side'.

Creationism in Crisis - The Periodic Greening Of The Sahara In That Vast Expanse of 'Pre-Creation' History.


Tassili N’Ajjer plateau, Algeria.
A once fertile savannah with lakes and rivers.
The Sahara Desert used to be a green savannah – new research explains why

Having visited the Sahara Desert in April about 10 years ago, I can assure readers that it is not the hot, dry place of repute but can be cold and wet, at least in the Tunisian part. It was so cold with a fine drizzle, that, shivering in a t-shirt, I offered to buy the thick, hooded duffle coat a local troglodyte guide was wearing, but he quoted me 5000 dinars (about £400) with a knowing twinkle in his eye. I elected to shiver until I got back on the coach and the driver turned the heating on. Yes, there are troglodytes in Tunisia!

There have been times in the past when rain in the Sahara was not just freak weather in Spring to annoy tourists, but the norm in much of the year, so much so that the Sahara was mixed savannah and scrub with lakes and rivers, especially the western part.

Readers may recall how I mentioned the periodic greening of the Sahara in my article about the evolution of rock doves and feral pigeons. Briefly, a species of dove resident in West Africa crossed the Sahara during one such period when there was forest, grassland and water in place of sand. Then when the Sahara became desert the two populations diverged and the one which had made it as far as the Middle East hybridized with a resident related dove. This hybrid quickly became the normal form of the rock dove north and east of the Sahara and diversified further into several subspecies, one of which was domesticated and selectively bred to produce lots of different varieties. Some of these eventually reverted to a feral existence and became the ubiquitous town pigeon with a very different lifestyle and habitat to the original rock dove.

This process of African species moving into and across the Sahara during these periods of greening, and then becoming isolated from the African population, is known as the Saharah Pump and accounts for some of the sub-Saharan African species having a closely related counterpart in North Africa and Eurasia.

And this process has been going on since about 8 million years before creationists think Earth was created and may account for the migration of humans out of Africa some 40-50,000 years ago. More recently, however, there was certainly a population of humans living in a green and fertile Sahara up to at least 11,000 years ago (i.e., at least 1,000 years before 'Creation Week'. We know this because they left a record in rock carvings at Tassili N’Ajjer plateau in present-day Algeria, which show us some of the animals that lived there too.

These periods of greening have occurred approximately every 21,000 years and now two geoscientists from Helsinki University, Finland together with colleagues at Birmingham and Bristol universities, UK., have developed a climate model that explains how the climate changed so regularly and so radically. They have published their findings, open access, in Nature Communications. One of them, Edward Armstrong of Helsinki University, has also written an article about their research in The Conversation.

Creationism in Crisis - The Woolly Dogs Of The American Coast Salish People Predate 'Creation Week'


Researchers, Coast Salish People Analyze 160-Year-Old Indigenous Dog Pelt in the Smithsonian’s Collection | Smithsonian Institution

During that long period of Earth's 'pre-Creation Week' history, before anyone told the people of Siberia that they should wait to be created then wiped out in a genocidal flood before forgetting all about it and only then going to live elsewhere, they migrated to North America, taking their domestic dogs with them.

This is the sort of nonsense that creationism requires you to believe in order to reconcile the scientific evidence with the creation myths of a bunch of Bronze Age Canaanite farmers who thought Earth was small, flat and had a dome over it to keep the water above the sky out. Obviously, these people had almost certainly never heard of Siberia or North America or realised that there were other people living there and were as ignorant of most of Earth's long history as they were of cosmology, biology and geology.

One of the things the Bronze Age Canaanites would never have guessed was that some of the domestic dogs the Siberians took with them had genes for a dense wooly fur that could be woven into blankets and other fabrics, but now a team of researchers from the Smithsonian’s National Museum of Natural History have carried out a detailed DNA analysis of the pelt of the last known example of this breed of dog (a dog known as Mutton). Mutton died in 1859 and his pelt was sent to the Smithsonian Institute where it remained until it was rediscovered in the early 2000's.

The analysis has shown that the line diverged from the other dogs about 5,000 years ago (i.e., before creationist superstition says all life on Earth was exterminated in a genocidal flood when their 'all-loving' god flew into a rage because its creation wasn't working as intended).

They have shown that its closes genetic relationship is with the pre-colonial dogs from Newfoundland and British Columbia. The Indigenous Coast Salish communities in the Pacific Northwest (in Washington state and British Columbia) for millennia held these wooly dogs in high esteem, regarding them almost as family members and often keeping them in pens or on islands to prevent them interbreeding with other dogs, to maintain the quality of their wool. This isolation prevented the ingress of genes from other dogs and even from the dogs later colonists brought with them. The genes recovered from Mutton's pelt show that 85% of his genes were from pre-colonial dogs.

The Smithsonian researchers have, with the assistance of Coast Salish Elders, Knowledge Keepers and Master Weavers, now traced the place of the woolly dogs in Coastal Salish culture and the reasons for its decline. Their findings are published in Science and tell a sorry tale of colonial destruction of a people and their culture. Instead of, as has been suggested, the arrival of machinery and woven blankets made the wooly dogs expendable, the truth is that, due to disease and colonial policies of cultural genocide, displacement and forced assimilation, it likely became increasingly difficult or forbidden for Coast Salish communities to maintain their woolly dogs and a 1000 years or more of careful selective breeding was wiped out within a couple of generations.

Investigating the origins of life | CNRS News

Although it's nothing to do with evolution, which is the science of how living organisms respond to environmental pressures and diversify over time, abiogenesis is a favourite of creationists because they imagine, without being able to define 'life', that it must involve some magical, God-given quality that turns 'non-life' into 'life'. But then when did facts bother creationists?

So it must be disconcerting to those of them who are still in touch with reality, that 28 French scientific organisations, involving over 100 scientists, have formed a partnership (Programme et Équipement Prioritaire de Recherche - PEPR) led by the Centre National de la Recherche Scientifique (French National Center for Scientific Research - CNRS) to research into the origins of life, not only on Earth but on other planets. The project is already being known as 'Origins'.

Malevolent Design - How A Chicken Virus Got More Deadly - Malice Or Evolution?


Ancient DNA reveals how a chicken virus evolved to become more deadly | University of Oxford

Marek's Disease Virus (MDV) is a serious infection in chickens that costs th4e poultry industry over $1 billion annually. Now an international group of virologists and archaeologists led by researchers from Oxford University, Ludwig-Maximilians-Universitat, Munich, Germany, have discovered how it has evolved over time to become more virulent and deadly, or, as creationists insist, has been intelligently redesigned.

The team reached this conclusion from an analysis of the virus in modern and ancient chickens going back over the past 1000 years. The ancient samples were obtained from DNA extracted from chicken bones recovered from 140 archaeological sites in Europe and the Near East. This analysis showed that MDV was widespread in European chickens for at least 1000 year before being first described in 1907.

Creationism in Crisis - How Early Humans Caused A Decline In Megafauna Numbers Thousands Of Years Before 'Creation Week'


Peré Davids deer, Elaphurus davidianus. Now extinct in the wild.
People, not the climate, caused the decline of the giant mammals

About 90,000 years before creationist superstition says the Universe was created, humans, who had been evolving in Africa, began to expand their range into Eurasia and eventually into Austronesia and the Americas.

About 500,000 years later most large species show a sudden decline in their numbers, and now researchers led by Professor Jens-Christian Svenning, head of the Danish National Research Foundation's Center for Ecological Dynamics in a Novel Biosphere (ECONOVO) at Aarhus University, believe they have shown that this was due to human predation and habitat destruction.

They reached this conclusion from an analysis of the genomes of 139 species. This involved crunching the data from 3 billion or so data points to build evolutionary trees of the mutations in the genomes. The bigger the population, the more mutations there will be in the species genome, so this data shows the population changes over time.

Their work is published, open access, in Nature and is explained in a news release from Aarhus University:

Creationism in Crisis - Human Intelligence Is Not So Much A Matter of Quantity But Of Quality


Human intelligence: how cognitive circuitry, rather than brain size, drove its evolution

Researchers have shown that human intelligence does not depend primarily on the size of our brain - there are animals with bigger brains (elephants, orcas) - but on the cognitive circuitry.

The team, led by Valentin Riedl of the Department of Neuroradiology at Klinikum rechts der Isar, TUM School of Medicine and Health, Technical University of Munich, Munich, Germany, have published their findings, open access, in the journal Science Advances. It is explained in an article in The Conversation by two Cambridge University professors who were not involved in the research.

Unintelligent Design - Why Some Women Experience Morning Sickness during Pregnancy.


Why seven in ten women experience pregnancy sickness

'Morning sickness, which is common in the earlier stages of pregnancy, and which, in its more severe form, hyperemesis gravidarum, can be seriously debilitating and may even require admission to hospital and iv fluids to prevent life-threatening dehydration, is now known to be caused by a protein hormone, known as GDF15, produced by the foetal part of the placenta.

This discovery, published yesterday in Nature, by a team from Cambridge University, UK, led by Professor Sir Stephen O’Rahilly, and including researchers in Scotland, the USA and Sri Lanka, points to a potential way to prevent pregnancy sickness by exposing mothers to GDF15 ahead of pregnancy to build up their resilience.

Creationism in Crisis - The Evolution of the Mammalian Eye From A Common Origin Over 400 Million Years Before 'Creation Week'.


Human eye showing the iris and pupil
Cell types in the eye have ancient evolutionary origins | Berkeley

Despite the claims of creationists frauds who cite Charles Darwin, whom they falsely claim admitted the structure of the eye couldn't be explained, the evolution of the mammalian eye from a simple patch of light-sensitive cells is well known to biological science.

Darwin, of course, was setting out the problem before explaining the solution in a typical literary technique of his time. The paragraph that creationists often try to get away with citing is:

To suppose that the eye with all its inimitable contrivances for adjusting the focus to different distances, for admitting different amounts of light, and for the correction of spherical and chromatic aberration, could have been formed by natural selection, seems, I freely confess, absurd in the highest degree.

'Origin of Species', page 100

What they always fail to cite is the very next paragraph:

Yet reason tells me, that if numerous gradations from a perfect and complex eye to one very imperfect and simple, each grade being useful to its possessor, can be shown to exist; if further, the eye does vary ever so slightly, and the variations be inherited, which is certainly the case; and if any variation or modification in the organ be ever useful to an animal under changing conditions of life, then the difficulty of believing that a perfect and complex eye could be formed by natural selection, though insuperable by our imagination, can hardly be considered real.

Creationism in Crisis - How Wrong The Bible's Authors Were! Why Would Anyone Believe Anything Else They Wrote?


The Universe as described in Genesis 1: 6-10
NASA’s Webb Stuns With New High-Definition Look at Exploded Star - NASA

The description of the Universe in the Bible is so naïve and radically different to the real universe, it beggars belief that there are grown adults who think the Bible is the inerrant word of a creator god.

There is nothing about the authors' description of it which can be described as allegorical or metaphorical, without the most contorted of mental gymnastics. It is not metaphorical or allegorical; it is quite simply wrong; spectacularly and conspicuously, with no shadow of a doubt, wrong!

What we now know are hundreds of billions of galaxies, each with maybe half a trillion stars, many with planetary systems, the authors of the Bible thought were little lights stuck to the underside of a dome over a flat Earth, that can be shaken loose and will fall down to Earth where they can be trampled on by a goat! (Daniel 8:10).

They described this flat Earth with a dome over it as standing on pillars and the fixed and immobile center of the Universe, round which a small sun orbits. They described the sky above the dome as being made of water. Their universe ran on magic.
