A critic of Evolution thundered recently: “Scientific observations do not support biological evolution! What about the icons of evolution that have been presented in textbooks for almost 50 years? Don’t these icons support biological evolution? Some of these do show microevolution within species. This type of evolution, even if it permanently points in one direction, is not evolution. It is no more evolution than dog breeding.” (What???) “However, if a dog could be bred into a cat, that would be evolution. Even icons like the peppered moths that were only examples of microevolution, used pinned dead moths on black tree trunks that were not a natural resting place for the moths. Hackle’s embryos, ape-to-man drawings, the horse series, etc.”
The above is taken from a site urging the teaching of Creationism as an alternative to Evolution. That these words are incoherent are not the worst of their faults. Unfortunately, these remarks leave the question of evolution validity or falsehood. Not only are they erroneous, they are misconceived.
A fundamentalist reading of the Bible leads to all sorts of nonsense. In the 19th century, there occurs a belief in the spontaneous life. At one time, people maintained that the sun created crocodiles from the mud of the Nile. Mice were supposed to be created out of piles of old soiled rags. Bluebottle flies had their origin in bad meat. Maggots were created in apples, which is why they at last appeared. U.S. fundamentalists believe this as well. They do think that the earth is only 6,000 years old.
Alas, Louisiana, Tennessee and other states, clearly striving to be in the forefront of every backward movement, are increasing funding for the teaching of “Creationism” in schools there, demonstrating their support for this falsehood by thumping their cave man’s clubs or perhaps enacting animal sacrifices. The problem is that the advocates of Creationism are spiritual and mental primitives. They haven’t evolved at all.
The Creationist folks clearly don’t understand that Evolution is not really a controversy anymore. Evolution is no longer a theory because the debate has long ago moved from biology to chemical analysis. The building up of chemical molecules defines our Life’s beginning. What we have learned from scientists since Darwin is that the cycles of life have a chemical form. Scientists had to do much selfless work to learn how to express the cycles of life in a way that linked them to nature as a whole, and this meant studying chemistry. That’s what the Bible believers get wrong.
In other words, scientific knowledge has moved way, way beyond Alfred Russel (sic) Wallace, and Darwin and Mendel. The blood that flows in our veins is millions and millions of years old. The history of the Earth is interesting to the point of fascination, but the man who solved the mystery of life’s earliest origins was the Frenchman Louis Pasteur who proved the chemical basis of all human life back in 1863, when the French Emperor asked him to solve the question of why wine went bad. Pasteur solved this in two years. He discovered that the wine was a “sea of organisms.” He said, “By some it lives, by some it decays.” What was the most startling of his discoveries was that life could exist without oxygen. He found that no free oxygen existed before Life existed.
After Pasteur, it was chemists, not biologists that began to look at amino acids as the building blocks of human life. When anyone of us moves his or her arm, we rely on something called myogiblin which consists of 120 amino acids. The difference in amino acids between a chimpanzee and a human is a small difference. But between a human and a sheep, the difference of amino acids is much greater. Yet the overwhelming conclusion about our life’s origins is that they have their base in chemistry, in molecules that can replicate. Basic molecules form DNA chains, etc. In fact, our life is controlled by four bases of DNA.
The Earth’s Beginnings
It is perhaps chastening to note that by 8 billion years ago, about two thirds of the history of our universe passed, and it had passed before the creation of the Earth which took place around 4.6 billion years ago. It was around 4.6 billion years ago that a mass the size of Mars crashed into the Earth at 25,000 miles per hour. There was a huge amount of dust that circled us, but our gravity held on to it and out of that dust the Moon was formed. I believe that it was the moon that gave us 24 hour days and seasons. (A lot of the above is still being refined and debated, so please be patient with my mistakes.) So we humans were born out of chaos, collisions, ice ages, volcanic eruptions, and the like. No wonder we are so quarrelsome.
Scientists returned to the beginning, asking, what was the surface of the Earth and what was our atmosphere like? From my own fitful reading, I discovered from reading was that the atmosphere of the Earth was originally a mixture of steam, nitrogen, carbon dioxide, ammonia, methane, but no free oxygen. A great step forward occurred in 1952 or thereabouts, thanks to a scientist named Steven Miller, who, with a colleague named Harold Urey, bottled up in a flask what they guessed was the Earth’s original atmosphere. Theirs was an experiment intended to simulate the conditions thought at the time to be present on the early Earth, and the experiment tested for the occurrence of our chemical origins of life. Specifically, the experiment tested Alexander Oparin's and J. B. S. Haldane's hypothesis that conditions on the primitive Earth favored chemical reactions that “synthesized organic compounds from inorganic precursors.” (This language for me is a bit like tramping through a dense thicket in the woods and getting lost, but it is interesting nonetheless.)
So Miller bottled up nitrogen, water, methane, ammonia, water, carbon dioxide, and other reducing gases. The mixture turned pink within a day. For days he and Urey subjected their flask to heat, to ultra-violet light, loud noises, trying to simulate the chaotic fury of the Earth’s original atmosphere. This went on for some time, maybe weeks. Suddenly as Miller and Urey looked on, they saw that the pink liquid had suddenly darkened. Their experiment had produced basic amino acids, rudimental protein. The experiment was seen “as the classic experiment of the origin of life.(*)
A Wikipedia entry notes, “After Miller's death in 2007, scientists examining sealed vials preserved from the original experiments were able to show that there were actually well over 20 different amino acids produced in Miller's original experiments. That is considerably more than what Miller originally reported, and more than the 20 that naturally occur in life. Moreover, some evidence suggests that Earth's original atmosphere might have had a different composition from the gas used in the Miller–Urey experiment. There is abundant evidence of major volcanic eruptions 4 billion years ago, which would have released carbon dioxide (CO2), nitrogen (N2), hydrogen sulfide (H2S), and sulfur dioxide (SO2) into the atmosphere. Experiments using these gases in addition to the ones in the original Miller–Urey experiment have produced more diverse molecules.[8]
There was another man of genius, Leslie Orgel, who also worked with Miller. There is hardly anything about him on his Wikipedia site, but somewhere I had squirreled notes on him back in the 1980s. Orgel was a Brit, breathtakingly brilliant, and he used ice as a research tool to discover more about the basic elements of air. Freezing things was a way of concentrating them. He froze ammonia, hydrogen cyanide, methane, and some other elements of the atmosphere. He produced amino acids, but he produced something else too something much more important. He produced one of the four constituents of the genetic alphabet, which directs all life. He had in fact discovered adenine, one of the four bases of DNA. He ended by forming organic molecules, a big advance of our understanding.
I did find note of other achievements of his. “During the 1970s, Orgel suggested reconsidering the panspermia hypothesis, according to which the earliest forms of life on earth did not originate here, but arrived from outer space with meteorites.
His name is popularly known because of Orgel's rules, credited to him, particularly Orgel's Second Rule: "Evolution is cleverer than you are."
I am slowly realizing that the ability to analyze a batch of facts requires a certain kind of reasoning. It requires the talent of absorbing an abstraction. To be astute means we have to be a good observer. J.S. Mill once said “The observer is not he who merely sees the thing which is before his eye, but he who sees that parts the thing is composed of.” Someone like me, sees a fact or make an observation, but I don’t realize its particularity. I get only a very general and inadequate view, a hazy gist of the thing. I don’t detect similarities to other observations. But the scientist breaks up the observation and notices the particular attributes of it. He suddenly sees what the rest of us don’t – that the observation has properties which the original, basic observation didn’t have.
I really think that the dedication, the colossal capacity for focused effort, the self-effacing patience, the subordination of the appetite for glory in the service of solid achievement, the building of the powers of analysis in order to define a problem by breaking it down into its simplest elements, then testing a combination of them under different circumstances so something substantial can be proved -- that is and was – nothing short of a miracle to me. And I cannot imagine that God could not help but feeling affection and admiration for the intelligence in the creatures He created.
In the end, science is a test of temperament and mind that underlies a culture. Creationism fails that test.
(*) UPDATED KNOWLEDGE “Originally it was thought that the primitive secondary atmosphere contained mostly ammonia and methane. However, it is likely that most of the atmospheric carbon was CO2 with perhaps some CO and the nitrogen mostly N2. In practice gas mixtures containing CO, CO2, N2, etc. give much the same products as those containing CH4 and NH3 so long as there is no O2. The hydrogen atoms come mostly from water vapor. In fact, in order to generate aromatic amino acids under primitive earth conditions it is necessary to use less hydrogen-rich gaseous mixtures. Most of the natural amino acids, hydroxyacids, purines, pyrimidines, and sugars have been made in variants of the Miller experiment.[citation needed]
More recent results may question these conclusions. The University of Waterloo and University of Colorado conducted simulations in 2005 that indicated that the early atmosphere of Earth could have contained up to 40 percent hydrogen—implying a much more hospitable environment for the formation of prebiotic organic molecules. The escape of hydrogen from Earth's atmosphere into space may have occurred at only one percent of the rate previously believed based on revised estimates of the upper atmosphere's temperature.[23] One of the authors, Owen Toon notes: "In this new scenario, organics can be produced efficiently in the early atmosphere, leading us back to the organic-rich soup-in-the-ocean concept... I think this study makes the experiments by Miller and others relevant again." Outgassing calculations using a chondritic model for the early earth complement the Waterloo/Colorado results in re-establishing the importance of the Miller–Urey experiment.[24]”

TTG, Interesting. The NDE experience I mentioned was a number of years ago. As a result I too developed an interest in practical use of altered states of awareness. I too find remote viewing and that sort of thing to be valid and achievable (though I'm certainly no adept). Thanks for sharing.

Optimax, I am certainly not condemning all science. I am just commenting that science is often not science, but faith/belief.
Obviously the scientific method, objectively applied, is a very powerful way of understanding and manipulating the physical realm.
Posted by: no one | 21 April 2014 at 08:13 PM
at no one- I agree with you about the Big Bang theory and about the 13.8 billion years since it happened. For example, if Einstein's theories are correct (here Babak may add his thoughts) - than the time counting in our solar system time units must be wrong, for the simple reason that the expansion of the universe in the first few seconds or hours was happening at the speed of light and therefore any counting of time was impossible, there was no reference system from which to observe the whole spectacle!So, the time since it cannot be extrapolated backward, because the time stood almost still due to the speed of the expansion.
I am totally confused.. and still happy to be alive..:)

I understand that. Some people like to preach instead of discuss no matter the system of thought. People that think they know everything because they are good at something are the worst.
This post has rekindled my interest in biology, something I haven't study since college, and then not deeply. Just bought "DNA: The Secrets of Life" by James D. Watson.
Thank you, Richard.

I was interested in astral projection at one time. Never did have a successful and intentional launch. Decided it was best to stay were I'm at. Have been interested in herbal medicine. A distant relative of mine during the end of the 18th century was known for his apple cider vinegar cures--Dr. Josiah Bartlett.

TTG,
"Fruit flies have been fully speciated (no successful interbreeding) in the lab after 25 generations (fruit fly generations, that is.) "
My understanding is that whether or not such speciation has actually been observed is still an open question (see link for example).
http://www.evolutionnews.org/2012/01/uncooperative_f055311.html
"The Galapagos Finches speciated over millions of years. "
But, millions of year later, they're still finches.
"Given the 98% similarity in human - chimpanzee DNA, it probably doesn’t take that many mutations. It just has to be the right mutations or combination of mutations."
We also have 50% DNA similarity to a banana. Our genetics are so similar to the African Clawed Frog that the frog is being used to study human diseases, like cancer, and potential cures. The point being that a valid alternative perspective on genetic similarities is simply that DNA is the building block of carbon based organic life forms so a) all life forms contain DNA b)the more similar the life form, the more similar the particular DNA blocks used to build it.
It doesn't necessary follow that because the blocks are similar, one life form must have evolved out of the other (or both from a common ancestor). I understand that once you've tossed out God, this seems like a temptingly reasonable answer to "where did we all come from". Unfortunately, it also causes a necessary fallback to some very comic book-esque unprovable positions; lighting bolts striking primordial ooze, big bangs, etc.
Then you have the problem of what is awareness/consciousness and how does something immaterial arise amidst the material. OTOH if consciousness is primary, then what is to say that there isn't some thought behind speciation as opposed to random mutation theory?

Tyler:
I used to be in the science education business, but not any more, so pardon me for not bothering to explain basic principles of biology to you.
The most important thing I did learn from teaching was that there's no point in presenting knowledge until the student is ready to listen, and with all due respect, I doubt that's the case here. Your noise-to-signal ratio is way too high to permit the kind of listening that leads to understanding.
My advice to you for answering your questions is a suggestion that our host here at SST regularly employs: go look it up! I'm sure Wikipedia has lots of information on the topics you're so concerned about. So look them up!
And you've taken the right tack here: I suggested that if you wanted to disagree with what I wrote, then engage me in a technical debate on my assertions. You chose not to, and frankly, that's the right choice for you.
Posted by: Cieran | 22 April 2014 at 06:10 PM
Not a theory: an observable. The production of heavier elements from lighter ones is a well-established principle of physics, and it's readily apparent from examining the spectra of stars, including supernova.
We happen to know a lot about the curve of binding energy (in large part thanks to the cold war arms race and its need for more advanced nuclear science understanding), and there's no substantial problems with the scientific idealizations of this particular topic.
If you're interested in where the missing pieces of science might be found, then good for you for having some skepticism, but you won't find many holes in this particular venue of science. It's well-understood, and equally well-validated by observation.
Posted by: Cieran | 22 April 2014 at 06:19 PM
WRC:
The term science generally refers to the process (the scientific method) and the product (those idealizations that we refer to as theories).
So while the method is important (essential, in fact), the products are equally important, as they are the discoveries of reproducible phenomena that we utilize to produce useful objects, e.g., technologies.
It's easy to figure out from context whether process or product is being referred to, so there's no need to limit the definition as you suggest.

TTG:
Thanks for your well-considered answer here. The point you make of time scales is especially relevant for questions of biology in general, and evolution in particular. It makes the notion of scientific proof much more complex and difficult than in most other fields of science.
The age of the earth is about 5 billion years, but recorded human history is about 5 thousand years, so we've been modern enough to record our presence here only for about one-millionth of the history of the planet. And if we consider the history of science (less than 500 years), then we've been studying the world around us for less than one-ten-millionth of its duration. And therein lies a big part of the problem.
Anyone who has studied even the rudiments of information theory will appreciate that it's hard to observe secular (i.e., slow) natural phenomena without an appropriately-lengthy span of observation. And we simply don't have that much experience for complex organisms like ourselves, so we look instead to faster-living organisms (e.g., fruit flies) and even to organisms that are barely alive (e.g., viruses).
And the fossil record doesn't help us much, because it's not like the processes of geology help to preserve the fossil record: quite the opposite is true. So nature is doing something of a strip-tease with us, tantalizing observers by uncovering bits and pieces of evidence, while hinting of fundamental processes that are too slow for us to readily observe.
Sometimes we get lucky. My favorite example is for those folks here who don't think the Big Bang ever happened. I guess it's not widely known that Penzias and Wilson discovered (and were awarded the Nobel Prize in Physics in 1978 for discovering) the cosmic background radiation that is the Doppler-shifted signal from the origin of the universe.
In other words, one can see the Big Bang, or at least, one can image it in the microwave region where motion has red-shifted it to. So there's no question of its existence: it's an observable, not a mere theory. We can't see what preceded the Big Bang, but those questions may not even lie in the intellectual venues that can be determined by science. Science deals with reproducible phenomena, and "the creation of the known universe" is clearly a once-in-a-universe-lifetime not-particularly-reproducible affair.
Evolutionary science has not yet been so lucky as cosmology to get a multi-billion-year-old stroke of luck validating its predictiveness, but there are plenty of other forms of validation available, e.g., molecular biology. Apparently those forms of evidence aren't enough for some folks to be comfortable with the scientific idealizations, but old ideas die hard, both within the domain of science and outside of that intellectual realm.
As always, thanks for your comments here.

Cieran, What I here you saying is that you can't answer the questions, then you trot out some credentials to back up your condescension and dismissal. The assumption that someone who questions your beliefs hasn't been educating properly is classic because, why, after all, everyone just knows.....
And seriously, Wikipedia? That's a source recommended by a science educator?
Incidentally, have you, as an educator, ever read Rupert Sheldrake's theory of morphic resonance? http://www.sheldrake.org/
Sheldrake has serious creds as a PhD biology researcher and an educator (Cambridge I think it is). He too pokes a lot of holes in the standard evolution theory. Some are the same holes as presented by people on this thread. Sheldrake's theory fills those holes nicely and has one foot squarely in intelligent design and the other in biological processes.
Ever heard of him? Go ahead, look it up.

You accuse Cieran of trotting out his credentials, in which reality he went much deeper than that, and then say Sheldrake should be believed because of his "serious creds." Are you being ironic. I read a little of Sheldrake from your link and he is what we use to call a new ager. I no longer waste my time on such nonsense. My ex was into that but I realized that modern medicine is more efficacious than crystals waived over a body. That was many years ago.

'Members of the scientific community who have looked at morphic resonance have characterised Sheldrake's claims as being pseudoscientific. Critics cite a lack of evidence for morphic resonance and an inconsistency of the idea with data from genetics and embryology, and also express concern that popular attention from Sheldrake's books and public appearances undermines the public's understanding of science.[a] Despite the negative reception Sheldrake's ideas have received from the scientific community, they have found support in the New Age movement,[26] such as from New Age guru Deepak Chopra.[27][28] Sheldrake argues science should incorporate alternative medicine, psychic phenomena, and a greater focus on holistic thinking.[29]'
'Morphic resonance is rejected by numerous critics on multiple grounds, and has been labelled pseudoscience and magical thinking. These grounds include the lack of evidence for the hypothesis and the inconsistency of the hypothesis with established scientific theories. Morphic resonance is also seen as lacking scientific credibility for being overly vague and unfalsifiable. Further, Sheldrake's experimental methods have been criticised for being poorly designed and subject to experimenter bias, and his analyses of results have also drawn criticism.[b]'
'Sheldrake questions conservation of energy; he calls it a "standard scientific dogma",[29]:337 says that perpetual motion devices and inedia should be investigated as possible phenomena,[29]:72–73 and has stated that "the evidence for energy conservation in living organisms is weak".[29]:83 He argues in favour of alternative medicine and psychic phenomena, saying that their recognition as being legitimate is impeded by a "scientific priesthood" with an "authoritarian mentality".[29]:327 Citing his earlier "psychic staring effect" experiments and other reasons, he stated that minds are not confined to brains and remarks that "liberating minds from confinement in heads is like being released from prison".[29]:229 He suggests that DNA is insufficient to explain inheritance, and that inheritance of form and behaviour is mediated through morphic resonance.[29]:157–186 He also promotes morphic resonance in broader fashion as an explanation for other phenomena such as memory.[29]:187–211'

Sheldrake provided an answer. Cieran said "lol Wikipedia".
You're really conflating the two? Like I said earlier, as with global warming alarmists you can't question evolution without its cultists jumping around the question at hand.
Posted by: Tyler | 23 April 2014 at 08:05 PM
Because science is less about answering questions and more about "proving my voodoo right - at any costs".
There's big money to be made inventing new reasons for things like the 'achievement gap'. Not so much for pointing out the reality staring us in the face.
Posted by: Tyler | 23 April 2014 at 08:07 PM
Not even close, Tyler. In fact, posters like "no one" should be careful of what they ask for, because they might just get it.
Like Optimax and GCP, I did take the opportunity to review Mr no one's "serious creds" authority, and Dr. Sheldrake is nothing more than yet-another new age huckster. He does have a Ph.D. (1967 in biochemistry) but on a quick examination of his web pages, it looks like he hasn't published anything scientific in decades.
And it seems that he managed to disappear from his technical field right around the time that it got really interesting, so he's contributed nothing I can find in his pseudo-CV to all the recent real-world science advancement of biochemistry topics like computational simulation of protein folding. He's missed all the excitement in his field while writing deep tomes with titles like "Dogs That Know When Their Owners Are Coming Home" instead.
If this guy Sheldrake is the kind of figure that you and no one think is an expert, then heaven help you on the topic of science, because nothing Sheldrake is doing is remotely scientific. Scientific theories are by definition predictive and verifiable, and Sheldrake's work is neither.
What I find downright hilarious about the whole thing is that "no one" raises Sheldrake up as some kind of expert on what's missing from Darwinian evolution. But Sheldrake's assertions on pseudoscientific pap like "morphic resonance" are so chock-full of technical holes that Darwin's work looks rock-solid perfect in comparison.
Ahhh, the irony...
