Refuting Creationism - How The Ice Giants Created Complex Life In The Oceans


Glacial grooves stemming from the Wisconsin glaciation at Kelleys Island, Ohio

Giant ice bulldozers: how ancient glaciers helped life evolve - News at Curtin | Curtin University, Perth, Australia

It's generally recognised that complex, multicellular life began in the oceans from colonies of single-celled organisms, but what isn't known is what environmental triggers promoted the evolution of this complexity.

Now researchers from Curtin University, Perth, Australia, in collaboration with the University of Portsmouth and St. Francis Xavier University, Canada, believe they have shown a correlation between this event, or series of events and the melting of vast ice sheets which covered Earth in a period known as snowball Earth. The trigger was not so much the melt-water and rise in sea levels as the minerals this melt-water brought with it. This sudden abundance of minerals was the result of the slow grinding of Earth's surface by giant glaciers as they gouged their way across the planet.

The inner ear of Neanderthals reveals clues about their enigmatic origin

Creationists will confidently tell you that a loss of genetic information is invariably fatal so can play no part in evolution. They believe this because the frauds at the Discovery Institute have misled them into believing that every piece if DNA and therefore every piece of genetic information has a purpose.

And yet researchers have shown that it was a loss of genetic information following a population bottleneck that gave rise to the classic Neanderthals as a distinct species from their pre-Neanderthal ancestors.

This was the conclusion from a study led by Alessandro Urciuoli (Institut Català de Paleontologia Miquel Crusafont, Universitat Autònoma de Barcelona) and Mercedes Conde-Valverde (Cátedra de Otoacústica Evolutiva de HM Hospitales y la Universidad de Alcalá), researchers measured the morphological diversity in the structure of the inner ear responsible for our sense of balance: the semicircular canals.

Malevolent Designer - How Creationism's Divine Malevolence Ensured Its Zika Virus Infects Developing Babies

Stealth virus: Zika virus builds tunnels to covertly infect cells of the placenta | BCM

I've written recently about the lengths creationism's divine malevolence must have gone to to ensure one of its nasty little parasitic pathogens, the zika virus, gets to infect as many of its potential victims as possible. Science has now revealed how it then ensures as many babies being carried by its pregnant victims as possible are infected, by sneaking past the maternal/foetal barrier in the placenta.

Zika, is, of course, the mosquito-borne virus that causes microcephaly and associated mental handicap in babies whose mothers were infected during pregnancy.

To ensure the success of this method of increasing the suffering in the world, the designer had a major problem of its own making to overcome - it had given the human foetus a placenta that included a barrier between its circulation and that of the mother. This barrier is normally sufficient to prevent viruses crossing over into the developing foetus, so clearly, if an many children with microcephaly as possible are born, the designer had to find a way to bypass this barrier.

It produced the ingenious method of creating microtubules (small tunnels) between the mother's cells and the foetus's cells in the placenta and simply passing through them!

Unusually for creationism's divine malevolence, which normally behaves like a mindless evolutionary process and reinvents a novel solution for the same problem encountered by a different species, this is the same sneaky method used by a few other viruses to pass from cell to cell in a sheet of tissue, without going outside and making themselves available for the immune system to detect and respond to.

Refuting Creationism - A Simple Mutation Could Have Given Us the Power of Speech.

The Rockefeller University » A single protein may have helped shape the emergence of spoken language

In the simplistic creationist parody of evolution, intelligently designed to make cult members feel superior to real scientists, the evolution of something like speech in humans must have involved complex, specified, information, that humans alone have that other, lesser, species don't have. Of course, this could only be the result of intelligent design by a supreme intelligence who favours humans, its special creation, who can be whichever your favourite deity is, although it’s not religion because it doesn’t mention God or the Bible. Got it!

The surprising thing is that neither William A. Dembski, nor Michael J. Behe, leading Deception Institute fellows, have written a widely acclaimed (in creationist circles and in selected magazine and newspaper articles emanating from the Deception Institute, for its brilliant conclusive proof of the failure of 'Darwinism') book, detailing the sheer astounding complexity of the genetic basis for human speech, and how this proves we don't share a common ancestor with the African apes.

Perhaps they were aware already of the fact that the genetic basis for human speech involves, no such complexity, but just a single point mutation in a gene we share with the other apes and many other mammals.

Rather than proof of human exceptionalism, our ability to speak turns out to be evidence for common ancestry.

The mutation was discovered by researchers from The Rockefeller University and is a simple substitution of the amino acid isoleucine for valine, in the protein NOVA1 which resulted from the substitution of guanine (G) in the first position in the codon for isoleucine for adenine (A). So, the simplest of all mutations - a single point substitution of one nucleotide for another in a gene, may have enabled humans to speak.

Malevolent Designer News - How a Fungus Makes Its Host Destroy Its Own Brain

Fungus ‘hacks’ natural immune system causing neurodegeneration in fruit flies - University of Birmingham

If we are to believe creationists, their god created insects such as fruit flies, Colorado beetles, etc., and then set about devising ways to kill them with, amongst other pathogens, fungi that infect them and destroy them from inside.

One of the problems this supposedly intelligent designer had to overcome was the immune system it had given the insects in order to protect them from the pathogens it was designing to kill them.

According to an open access paper just published in PLOS Biology by a team led by Professor Alicia Hidalgo from School of Biosciences, The University of Birmingham, one species of parasitic fungus, Beauveria bassiana, cleverly turns its host's immune system against its host, making it destroy its own brain. Although this fungus does not affect mammals, so poses no threat to humans, the team warns that it is possible that another fungus could use a similar technique against mammals, including humans.

Creationism in Crisis - Scientists Are Questioning Human Evolution - But Not In The Way Creationists Had Hoped



A new model upends the decades-old “hard steps” theory that intelligent life was an incredibly improbable event and suggests that maybe it wasn't all that hard or improbable. The team of researchers said the new interpretation of humanity’s origin increases the probability of intelligent life elsewhere in the universe.

Does planetary evolution favor human-like life? Study ups odds we’re not alone | Penn State University

An interdisciplinary team of astrophysicists and geoscientists has questioned the evolution of a human-like intelligent species. But the question is not about whether, as creationists have been predicting for 50 plus years, but just how easy or difficult was it? That we evolved was never in any doubt.

The relevance of the easy/difficult question is that it affects our calculation of the probability of similar intelligent life evolving on other planets. If each step in its evolution was hard (the 'hard step' model), then we may be alone in the Universe; if easy, then the Universe could be teeming with life.

Malevolent Designer News - How Cancer is Cleverly Designed to Trick Our Immune System


Mitochondrial transfer and metabolic reprogramming of the tumor microenvironment aid cancer immune evasion.
How Cancer Cells Trick the Immune System by Altering Mitochondria - Okayama University

There is an ongoing arms race between medical science and cancer - and guess whose side creationism's intelligent designer appears to be on.

Yep, it's the same intelligent designer who designed cancers in the first place by creating an error-prone DNA replication mechanism that goes wrong, as does the error-correction mechanism it designed to try to rectify its faulty design with an added layer of complexity. And one of the results of it going wrong is cancer.

One of the more hopeful treatments for cancer was a tailor-made immunotherapy in which specific antibodies to the cancer cells were used to attack the cancer and treat it like a parasitic pathogen, by training the immune system to recognise the cancer and attack and destroy it.

But, true to form, creationism's divine malevolence has hit back by designing a response by cancer cells to attack by cells of the immune system.

We can be sure this is the work of creationism's intelligent designer because William A Dembski, the Discovery Institute's flunky and pseudoscientist in residence, tells us that any genetic sequence that produces a function must have been given 'specified information' in the form of the DNA that codes for that specific protein because, so he claims, specified information is too complex to have evolved.

Creationism Refuted - The Real Universe Shows Us The Bible's Authors Just Make Stuff Up -


Close-up of the Einstein ring around galaxy NGC 6505
ESA - Euclid discovers a stunning Einstein ring

No matter how much you insist that words meant something different in those days, or the description is a poetic allegory or a metaphor the meaning of which is beyond us, the early verses of the Bible clearly and unambiguously describe a universe consisting of a small flat planet with a dome over it with the sun, moon and stars stuck to the underside of the dome.

This, of course, is a childlike description of what the authors saw as they looked up into the sky and saw what looked like a dome, and Earth was more or less flat, give or take a few low hills, so that is what, in their child-like naivety, they described:
How the Bible's authors saw the Universe.
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.

Genesis 1.6-10

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.

Genesis 1.14-18
Now, as we learn more about the Universe as we develop increasingly sophisticated scientific instruments for examining it, we discover just how childishly naïve the Bible's authors were and so show to anyone interested in truth that the Bible could not possibly have been written or inspired by the creator god described in it, unless that god wanted to mislead us so that it would take humanity another three thousand years or more to discover its lies - and what would have been the point of that?

Mind you, the same creator god could have told us about germs, atoms or electricity or how to make a steam engine or a motor car, but either chose not to or didn't know about those things, because the people who invented it didn't know about those things either. What 'science' there is in the Bible is no better than the primitive understanding of Bronze Age pastoralists.

Abiogenesis News - Closing Another of Creationism's God-Shaped Gaps - Still No God Found


How life’s building blocks took shape on early Earth: the limits of membraneless polyester protocell formation – ELSI|EARTH-LIFE SCIENCE INSTITUTE

Creationism’ ever-shrinking little god that sits in the abiogenesis gap, just got smaller with the news that researchers led by PhD student Mahendran Sithamparam of the Space Science Center (ANGKASA), Institute of Climate Change, National University of Malaysia, working at the Earth-Life Science Institute (ELSI) in the Institute of Science, Tokyo, Japan, have shown how primitive protocells could have formed under a wide range of realistic probiotic Earth conditions. The research team included scientists from Taiwan and China.

The research showed that membraneless protocells could have formed by polymerization of alpha-hydroxy acids (αHAs) to form polyester microdroplets, not to be confused with the modern plastic polyester. These polymers were polymers of esters - simple organic compounds which are chemically similar to the monomers that make modern polyester fibres.

Unintelligent Design - How Creationism's Heath-Robinson Designer Muddles Through But Still Messes Up.

Spliceosome: How Cells Avoid Errors When Manufacturing mRNA

Q. How can you tell when something is designed by a supreme intelligence with the inerrant ability of foresight?

A. It works perfectly, without errors and does exactly what it was intended to do, nothing more and nothing less.

Q. How can you tell when something is 'designed' by a natural, utilitarian process like evolution by natural selection?

A. It works most of the time, even if not very efficiently, is over-complex and so prone to errors and doesn't anticipate change. It also frequently requires additional layers of complexity to compensate for its errors and inefficiency.

Sadly for intelligent design advocates, structures and processes found in nature are almost never perfect and free from errors and, when examined closely, are seen to be error-prone, suboptimal and requiring additional complexity to compensate for the errors and inefficiencies. And these error-correction mechanisms are themselves error-prone and prone to failure.

One such mechanism, the details of which have just been worked out by researchers at the Heidelberg University Biochemistry Center (BZH) in collaboration with colleagues from the Australian National University, is the system of spliceosomes found in eukaryote cells, that correct the errors in messenger RNA (mRNA) before they are transcribed into functional proteins.

The reason these large nuclear proteins are required is because the DNA the mRNA is transcribed from is contains 'introns' - small sequences that are not part of the gene being coded for. Imagine a computer database of words, which, when a retrieved, inserts random letters in the middle of the word.

Refuting Creationism - 183-Million-Year-Old Fossilised Soft Tissue - Stand By For Creationist Lies


Soft tissue from a 183 Million-Year-Old Jurassic Plesiosaur analysed | Lund University

Some palaeontology finds must seem like a god-send to creationist cult leaders looking for something to misrepresent to their dupes, but it has been a few years since Dr. Mary Higby Schweitzer's team reported finding 'soft' tissue in a fossilised dinosaur bone.

Creationists routinely misrepresent this discovery, particularly the discovery of soft-tissue structures in fossilised dinosaur bones. Schweitzer and her team found microscopic structures resembling blood vessels, cells, and proteins in well-preserved fossils, which creationists have seized upon as supposed evidence that dinosaurs lived only a few thousand years ago, rather than tens of millions. However, their claims are based on a fundamental misunderstanding—or deliberate misrepresentation—of both the science and Schweitzer’s own conclusions.

Far from supporting a young Earth, Schweitzer’s findings actually highlight the remarkable durability of biological molecules under specific conditions. Her research suggests that iron particles from haemoglobin help preserve proteins by acting as a natural fixative, similar to formaldehyde. This explains how soft-tissue structures can persist for millions of years without requiring the fossils to be "recent," as creationists falsely claim. Despite Schweitzer’s repeated clarifications that her discoveries do not challenge the vast timescales of evolutionary history, creationists continue to misquote her work to fit their pre-existing religious narratives.

This distortion is part of a broader pattern in which creationists cherry-pick scientific findings, strip them of context, and twist them to manufacture doubt about evolutionary theory. Rather than engaging with the scientific explanations provided by Schweitzer and other researchers, they rely on misleading rhetoric to persuade those unfamiliar with the complexities of molecular preservation. In doing so, they not only misrepresent the science but also the integrity of the scientists behind it. Some creationists even claim the tissue was carbon dated to just a few thousand years old. This is a lie since no such dating was performed because carbon dating is only accurate on specimens less than about 50,000 years old and is never used to date fossils because the original carbon from the living animal is lost in the mineralisation process.

And now we have something else for the frauds to fool their dupes with and win new ignorant simpletons into the creationist cult.

It comes in the form of a report by researchers at Lund University in Sweden which concerns 'soft' tissue found in a fossilised plesiosaur. However, and this is something that creationists will ignore in their eagerness to misrepresent the find - the fossilised tissue is fossilised hard parts of skin, such as scales. There is no question of the fossils being soft tissue. Creationists will also dismiss the fact that the fossil is 183 million years old and will claim the presence of soft tissue 'proves' the dating method is flawed because it must only be a few thousand years old.

Unintelligent Design - An Arms Betwen The Sexes!


Male flies' better vision called the females' bluff | University of Gothenburg
When dance flies mate, females make themselves more attractive by swallowing air and laying their hairy legs along their bodies to look like they are full of eggs. New research shows that the males have developed better eyesight, probably to detect the deception.
As I showed in my books, The unintelligent Designer: Refuting the Intelligent Design Hoax and Unintelligently Designed Arms Races: How Nature Refutes Intelligent Design, the natural arms races that are ubiquitous in nature make no sense as the work of an intelligence. It is simply not an intelligent act to have an ultimately pointless arm race with yourself.

Arms races happen because one side doesn't know the other side's next move but falling behind could be ultimately fatal. Both sides have no option but to use the 'Red Queen strategy' of running ever faster just to stand still. It makes as much sense as playing poker with yourself. As the act of an intelligence, it would mean the designer sees the solution to yesterdays' problem as today's problem to be solved. It probably tells us a great more than they might wish us to know that creationists think this is a sign of supreme intelligence.
The latest such arms race to be revealed by science makes even less sense from an intelligent design perspective if that's possible. This one is an arms race between the sexes in an order of insects known as dance flies and is the result of the two different strategies the males and females use to ensure they get the best mate and so produce the fittest offspring.

Dance flies are (mostly) predatory flies that kill and eat other insects. To attracts a female, males perform a dance with other males in a flying display. The females attract a male by showing him her abdomen in full of eggs and she is ready to be inseminated. The male then pursues the female and presents her with a dead insect as food. She then allows him to mate with her. They will then go off and repeat the mating rituals so both will mate with multiple partners. The female then lays her fertilised eggs in damp soil where they hatch and live as larvae and pupa until ready to hatch and repeat the cycle.

It is in the females reproductive interest to attract the fittest males and she does this by flying in front of him to display a large body full of eggs, while the male concentrates his efforts of pursuing the female most likely to produce a large batch of eggs, and presenting her with a nutritious meal in return for mating with her.

Malevolent Design - How Sudan Virus is Cleverly Designed to Kill 50% of Its Victims

New Study Reveals How Sudan Virus Binds to Human Cells | Midwest Antiviral Drug Discovery (AViDD) Center

It's shaping up to be a thrilling month for devotees of creationism's divine malevolence as science finds out just how brilliantly its nasty little parasites are designed to make us sick and increase the suffering in the world, although quite why any normal person would worship a hate-filled sadistic psychopath is even more of a mystery than the mechanism by which it designs and creates organisms.

The latest is the details of how the Sudan virus (a variant of Ebola with a 50% 'success' rate in terms of deaths of its victims) has an improved method of binding to our cells to gain entry and start the killing process. Like Ebola, it binds to receptors on the cell surface, but because it has just 4 different amino acids in its coat proteins, it binds much more efficiently - a factor which probably contributes to its high kill rate.

Malevolent Design - More Brilliance from Creationism's Divine Malevolence

Hijacking of plasmin by dengue virus for infection - NUS Faculty of Science | NUS Faculty of Science

If you're a creationists who follows the latest science (if there is such a thing), you must be bursting with admiration for the ingenuity of your beloved intelligent designer for the way its brilliance at making us sick and spreading more suffering in the world is being revealed by science.

In the last few days, I've reported on how HIV, the virus that causes AIDS, is designed to hijack our cell's metabolic processes to ensure its own survival, and how the zika virus that cause the serious birth defect, microcephaly, in children if their mothers become infected during pregnancy, is brilliantly designed to make our skin produce more of the scent that attracts mosquitoes, so ensuring it is spread as widely as possible.

Now we have a superb example of this skill in malevolent design revealed by researchers from the National University of Singapore (NUS) who have discovered how the dengue virus is designed to make sure as many people as possible are infected by it. And this is breath-taking in its ingenuity. It is spread by the divine malevolence's favourite insect vector - the mosquito.

Refuting Creationism - How Bonobos Help Us Find Something When They Know We Don't Know Where It Is

Don't know something? Apes can tell | Hub

The thing about Creationists is that, whilst they can't make testable predictions and their claims are non-falsifiable, they nevertheless make claims, based not on what the evidence shows, but on what they would like to be true to be as important as they like to imagine they are.

For example, they claim that there are certain features of humans that distinguish us from all the other species (ignoring that all species have unique features, which is what makes them distinct species). Most of these claims will be about our intelligence, social interactions and ethics and our artistic and aesthetic abilities.

Curiously, because they reject the idea that our ability to empathise is the basis of our social ethics, preferring to claim they get their morals from their god because that makes them feel superior to people with a different religion or none, they nevertheless will assert that compassion is one of those uniquely human characteristics that sets us apart from the other animals, so is evidence of our special creation by a magic creator who created everything just for us.

But like so many of their claims, this one turns out to be not only not unique to humans but evidence of common ancestry with the other apes - in this case bonobos, our closest relative. Bonobos have the ability to realise when there is something we don't know and to understand when we need to be educated - something that psychologists beleved was a uniquely human ability.

Unintelligent Design - Sex Determination in Octopuses - For 480 Million Years

Octopuses have some of the oldest known sex chromosomes | OregonNews

Although few of them will know enough to understand why, the genetic basis for sex determination in different organisms is a problem for intelligent design advocates because it illustrates a few embarrassing things which can't be explained as the design of an intelligent designer.

Firstly, there are several ways in which gender is determines, rather than the single method a single intelligent designer of all living things would have settled for (see the AI information panel). Secondly, the actual basis is consistent within major clades such as mammals, birds and orders of insects such as Hymenoptera (Bees, wasps and ants), and thirdly, because the methods are unstable over evolutionary time, since the sex chromosomes are unpaired in the heterozygous gender, so the unpaired chromosome tends to acquire mutations, which are not corrected by cross over during meiosis, and the non-sex-determining genes tend to be conserved on the chromosome which is paired in the homozygous gender.

In mammals, this means that the Y-chromosome tends to degenerate; in some species of rodents, which have a short generation time and large litters, so evolution can progress faster than in most other mammals, the Y-chromosome has disappeared, to be replaced by an alternative sex-determining system. No intelligent designer worthy of the name would design a process that degenerates and need to be replaced every few million years.

Malevolent Design - How Zika Is Designed to Spread Maximum Suffering.

Zika uses human skin as ‘mosquito magnet’ to spread virus further | LSTM

January was something of a joyous month for devotees of creationism's divine malevolence. Following closely behind the news of how it brilliantly designed HIV to use our cells defences against us so making it better at infecting and killing us, we have news of another breathtakingly brilliant design of a nasty little pathogen - the zika virus that causes microcephaly in children if their mothers become infected during pregnancy.

This news is that it turns our skin into a living 'magnet' to attract the vector that spreads it - mosquitos - so ensuring it gets transmitted to as many victims as possible. It does it by altering a gene and protein expression in dermal fibroblasts, causing the skin to produce odours that are attractive to mosquitoes. In effect, calling them to come and feed.

Before creationists start bleating unscientific and biologically non-sensical nonsense about 'genetic entropy' and devolution allowed by 'sin' I should point out that no mutation that conveys a benefit on an organism can be regarded as 'devolutionary'. It is classic evolution by natural selection. And, as per William Dembski's gibberish about 'specified complexity', any complex DNA or RNA sequence that codes for a specific function must be regarded as 'specified complexity', using his argument, so must have been specified by a magic designer, according to his misuse of statistics and probability. Or perhaps a creationist could explain why such a highly specific function of converting a human gene to make special mosquito-attracting scents, is not an example of Dembski's 'specified complexity'.

So, how was this, in creationist terms, intelligently designed virus, discovered to have this touch of brilliance in its design? That was the result if a new study by an international team led by Liverpool School of Tropical Medicine. Their findings are published, open access, in Communications Biology.

Refuting Creationism - Humans Have Been Selectively Breeding Sheep Since 1000 Years Before 'Creation Week'

Ancient DNA history of sheep and humans - News & Events | Trinity College Dublin

Domesticated animals are an embarrassment for creationists who believe that their god created all the animals for the convenience of mankind, because just about every domesticated animal (or plant for that matter) has been highly modified by selective breeding to make it suitable for whatever purpose it was domesticated for.

An intelligent god could have made them fit for purpose in the first place, if it had really created them for mankind's convenience. This shows that either the creation myth is wrong, or the creator god lacked the foresight to know what humans would be using the animals for. So, we've had to modify them, in some cases. almost beyond recognition as the descendants of their wild ancestors, to make them fit for purpose.

And it gets worse when we discover that the domestication process began long before the same creation myth says all the animals were created in the same week as humans.

Sheep, for example, according to a study by an international and interdisciplinary team of researchers led by geneticists from Trinity College Dublin, and zooarchaeologists from Ludwig Maximilian University Munich and the Bavarian State Collections of Natural History (SNSB) were first domesticated over 11,000 years ago. An analysis of their genome also reflects patterns of migration in the human population, with whom sheep have been intertwined for over 11,000 years.

Unintelligent Design - Vestigial 'Fossil' Ear Muscles Still Try to Function


Muscles of the ear

‘A neural fossil’: human ears try to move when listening, scientists say | Biology | The Guardian

In my book, The Body Of Evidence: How the Human Body Refutes Intelligent Design I list very many examples of the sort of design only a fool would produce - examples of sub-optimal compromises in structures and processes that could have been less error-prone and more efficient in terms of resource use or function.

These also included vestigial structures and system that still exist, sometime causing problems such as appendicitis when the functionless appendix becomes infected, and the wasted metabolism in making all the tiny hairs on your body stand up in cold weather using the tiny arrector pili muscles and the autonomic nerves that supply them.

Now we have another example, involving the superior and posterior auricular muscles that once moved the ears in a remote simian ancestor, but now only serve as party tricks for the few of us that can wiggle our ears.

Refuting Creationism - How Horseshoe Crabs Have Evolved And Diversified


Indo-Pacific Horseshoe Crab, Tachypleus tridentatus

Preserving Asian horseshoe crab populations through targeted conservation strategies

In creationist mythology, horseshoe crabs have remained unchanged for 400 million years, so they prove there is no such thing as evolution and Earth is only 6-0,000 years old. Apart from the typical lack of joined-up thinking in that non sequitur, there are a couple of fallacy at work here.

Firstly, evolution does not necessarily involve major changes in the phenotype because it happens at the genetic level, so the genome is where we need to look to find evidence of it (or lack of it); secondly there is no requirement for a species that is already adapted to its environment to change unless its environment changes in a way that requires adaptation. This might include increased predation, depletion of food resource, major changes in temperature or oxygenation, increased competition from another species, etc.

With their child-like understanding of evolution, creationists assume a species must change into something else for evolution to happen.

In fact, as a team a research team led by Associate Professor Frank Rheindt from the Department of Biological Sciences at the National University of Singapore (NUS) Faculty of Science have now shown, there are four different species of horseshoe crab which have all diversified from a common ancestor.
