Response: You are perfectly correct that the species in the London Underground is not the same species as the Cx molestus elsewhere in the world (it was named in 1775 and I think it is more widespread than just Australia, such as the Middle East). And taxonomy has a rule that the first time a name is used in a genus, then it cannot be used for another species also in that genus. So either this species is not newly evolved, as the page you cite implies by equating the two species, or, more likely, this is a case of illicit synonymy - the London researchers did not check if that species name, or epithet, had been previously listed, which is unbelievably sloppy.

There is another possibility, entertained in this technical paper, that the species name has been applied on the basis of purely morphological characters - that is, on the basis of what it looked like. In that case, it might be that several real species have been called molestus because they have similar appearances.

None of this indicates that the Underground species is not a new one evolved from the Cx pipiens species, although it took genetic evidence to show this for sure. But it is bad taxonomy. Thanks for noticing and telling us.

  1. The moon dust argument is an error, based on measurements now over forty years old, and incorrect by several orders of magnitude. In fact, the amount of dust on the moon is perfectly consistent with its age, about 4.5 billion years. See our Moon dust FAQ, and also the creationist article Moon-dust argument no longer useful (offsite) in which Answers in Genesis advise creationists to drop this argument.
  2. Sedimentary deposits from volcanoes are layers of ash, nothing like the vast majority of sedimentary rocks which are usually deposited in water. Sedimentary rocks are notoriously hard to date. Dating is easier for igneous rocks from volcanoes, which are not sedimentary, and for which the speed at which they are deposited is irrelevant to finding when they were deposited. A good discussion on dating and the relevance of volcanic rock is available at Radiometric Dating: A Christian Perspective (offsite).
  3. The second law of thermodynamics is one of the most fundamental laws of physics, and it is certainly not in any conflict with any aspect of evolutionary biology. See Thermodynamics, Evolution and Creationism FAQs. Another good site is The Second Law of Thermodynamics in the Context of the Christian Faith (offsite).
  4. A finally, our understanding of sedimentary rocks is well informed by direct observation of the processes involved. There are a series of comments in the index to creationist claims under CD200: Sedimentation.

Response: From your feedback, it appears you may be quoting someone else. In a school this needs to be handled sensitively; but basically the paragraph you quote is a scattershot of many errors.
  • Our FAQ "Evolution is a Fact and a Theory" helps explain what the term "fact" and "theory" mean in science.
  • Our FAQ "Macroevolution" considers what macroevolution means. But the comments above indicate a rather more subtle confusion. The writer speaks of being made from the ground. This is quite true; but it is not evolution. Our bodies are built up as we grow, and we all grow from a single cell in just a few decades. We ingest food that is taken from other life but in the end the matter of which we are made nearly all comes from plants, and they grow from material found in earth, air and water; and when we die the atoms of our bodies return to be part of that cycle. Evolution is not about the material of which our bodies are made, but about the forms it takes. We inherit the forms of our parent; not the atoms of their bodies.
  • We have found many transitional forms and missing links. See Transitional Vertebrate Fossils FAQ.
  • The largest land animals lived in the past; but the largest animal that ever lived at all is the modern blue whale. The largest trees that ever lived are living today as well. Trees in the age of dinosaurs were smaller.
  • The stuff about global warming is just wrong. Noone proposes to reverse global warming by blocking sunlight with mirrors; and it is not physically possible to have layers of orbiting ice, or a flood from such the falling of such a canopy. See The Vapor Canopy Hypothesis Holds No Water.
  • Animals did not all disappear at the same time. There are mass extinctions that can be identified in the fossil record; but they are not indicated by a lot of animals dying at once. There is no increase in the number of fossils at the extinction events; just a boundary in time after which we no longer find instances of the species that died out at that time. We find fossils over millions of years before the extinction; and fossils continue to be found after the extinction; though missing a proportion of species that died out.

Response: "Evolution" is a phenomenon of biology, and so far as we can tell believes nothing.

But assuming you meant what the current best hypothesis of the origins of the earth was, as used by evolutionary biologists, it is something that astronomers, geologists and physicists tell biologists. And they tell us that the earth formed by the accretion of gases and solids in orbit about the Sun around 4.5 billion years ago, leftover from the solar disk that formed the Sun itself. About 3.85 billion years ago the earth cooled enough for life to form, and we have some evidence that it did almost immediately. And this has nothing whatsoever to do with evolution until life begins.

On the peppered moth, the example is supposed only to show how a variant can become widespread in a population due to the effects of the environment, in this case bird predation. Follow the link to find out more.

Certainly I get the feeling most of them are quite young. And so we ought to give them some slack - we cna only hope that if they actually do follow up the responses, they will get over their indoctrination.

But some of them are clearly adults, and for them lack of education is harder to overcome. I feel quite sorry for many of them.

Author of: Isochron Dating
Response: There's really not enough information there to know for sure what is going on. There are a few things I noticed:
  • The large total figure (1020g of He) is supposed to be the amount that would accumulate in 4.5x109 years. However, there are also 4.5x109 years for it to leak away. The total quantity over time is not important; it is the rate of production and loss that matters. The total quantity is a red herring that Milton only brings up because it sounds like an impossibly large number. The use of such devices implies that the argument is more polemic than science.
  • Milton is completely out to lunch on his claim that it was believed in the late '60s that there was no solar wind. The solar wind was discovered by Eugene Parker in 1958, after being theorized in the mid '50s. (See this National Geographic story for more detail.)
  • Milton's math doesn't seem to add up. His own numbers are 1020g of He in 4.5x109 years. That equals 103g/sec of He. Dividing by 4 (approximate atomic weight) and multiplying by 6x1023 (Avogadro's number), 103g/sec is 1026atoms/sec. The surface area of the Earth, and therefore the approximate surface area of the upper atmosphere, is about 1019cm2. Dividing the number of atoms/sec by the surface area yields 107atoms/cm2/sec. This rough calculation matches Dalrymple's numbers well, and is a billion times smaller than Milton's claimed 1016atoms/cm2/sec.

    I've debated Mr. Milton in the pages of Fortean Times, and in personal correspondence. I've caught him making several similarly silly statements -- statements that he would have known better than to make, if he had been able to perform some basic mathematics to sanity-check his own claims. There's not enough information in the Milton quote to be sure, but it appears to be the sort of mathematical error I've seen Milton make elsewhere.

  • Milton's claims about the solar wind adding helium to the Earth's atmosphere seem to be mere hand-waving. Helium has been measured to be escaping, directly; see for example: NASA Press Release: Solar wind squeezes some of Earth's atmosphere into space.
  • In the quoted section, there is no comment on Darlymple's second reference, which demonstrates that magnetic reversals would ensure balance between He production and loss. Since at this point even most creationists have owned up to the reality of magnetic reversals, that paper strikes a telling blow against their helium arguments as well.

I find it a little odd that a "prominent creationist" would reference Milton. The few creationists that I know with real science backgrounds do not take Milton seriously, and further would not want to give him credit (by referencing him), for merely uncritically repeating creationist arguments, which is pretty much all he does.

Response: There is a discussion of the issue, by Kevin R. Henke, at this site.

Briefly, Steve Austin collected a sample from the Mount St. Helens lava dome, known to be ten years old then, and sent it to a geochronology lab which tells people very clearly that the methods they use cannot give accurate dates on samples expected to be less than two million years old. In other words, Austin deliberately arranged for the dating to be invalid and then pretended it was someone else's fault.

It is also possible that part of the sample was millions of years old. Lava sometimes includes older rocks ("xenoliths"). Austin's sample includes crystals which may be xenoliths.

Response: So far as I know, and I am Vice President of the recently formed Talk Origins Foundation which we set up to defray the costs of running the Archive, and which at this moment has about $4500 from individual donations, we have received no other funding or support from anyone or any institution.

Compare this with the funding of the Discovery Institute [Also here, here, here, and here], or Answers in Genesis. Discovery has a budget of around 4m/yr, and AIG of $9m/yr. We little guys have around 1/1000th of DI and 1/2000th of AIG (which, it should be noted, makes $2m/yr profit).

From:
Response: John is a bit optimistic about the TalkOrigins Foundation's funding. As of this writing (September 13, 2005), the Foundation has received almost exactly $3,300 in donations, all from individuals. (That puts us even farther behind DI and AiG!)

The 2005 second quarter reports on the Foundation can be found on its home page. As the Foundation's secretary-treasurer, I'll be posting its financial and corporate data there.

Response: The day-age hypothesis has been put forward numerous times as support for the biblical account of creation. While it solves the time issue, it does nothing to solve the glaring inconsistencies in astronomy and paleontology. For example, light seems to appear before the sun is created, and birds are created before sea creatures.

It seems impossible to reconcile the biblical account of creation with scientific evidence. It demeans both to make the attempt.

Response: Amusingly, your spreadsheet presents one of the basic facts about life which was crucial for the initial recognition of evolution.

But first, here is what is wrong with your spreadsheet. Population growth does not follow a simple exponential growth rate over long periods of time. You don't need a spreadsheet to see this. If you assume a constant growth rate of half a percent, and start from a world population which is now 6.5 billion, then n years ago you have a population of 6.5*109*1.005-n. This implies 2000 years ago, the world population was about 300,000.

However, this is wrong by a factor of about 1000. Estimates of world population at that time are around about 300 million. The city of Rome alone had much more than 300,000 people within its walls.

Ergo, your numbers are useless and your conclusions meaningless. The assumption of simple uniform population growth is wrong.

On the other hand, your spreadsheet does demonstrate the dramatic consequences of exponential growth, and indeed when resources permit, population growth does tend to be exponential over short periods. Darwin comments upon this in Chapter 3 of Origin:

There is no exception to the rule that every organic being naturally increases at so high a rate, that if not destroyed, the earth would soon be covered by the progeny of a single pair.

The potential for unchecked population growth is vastly greater than what has plainly occurred in history. That is, world population is now 1000 times less than what would have occurred over the last 2000 years under your simplistic assumptions.

There is of necessity a competition for contribution to future generations, and this is the basis of natural selection.

...you quit responding to me after you couldnt explain how plants could live without pollinization for millions of years.

I assume you are referring to plants existing before the evolution of the specific insects that pollinate them? If so you need to consider that not all plants need pollination and not all pollination is done by insects. Some plants really are pollinated by the wind.

I would like to say though you keep saying that there is tons and lots of evidence for intermediates species but you only present a few skulls which could be classified and fully human or fully ape.

That is simply a false statement. We have quite a bit of material on transitions. We are not merely presenting a few skulls. As for a human evolution why don't you answer some questions which we have a hard time getting creationists to answer.

In the following, what are the apes and what are the humans?

Plenty more fossil evidence can be found in our section on human evolution. I in particular would want a response to the Dmanisi fossils. I would then like to know why other creationists disagree with where you draw the line between humans and apes.

And you only gave one example of a bird to a dinosaur which can be classified as fully bird.

Archaeopteryx is classified as a bird only in the sense that Linnean classification requires that any organism is or is not a member of a taxon. Please tell us why you don't think that these fossils should not be considered transitional? As for being being the "only" example, this web site could use additional articles on the other transitions between bird and non-bird. We do have some links and references though.

You know birds found today have tailbones, go ahead look it up, RIGHT NOW!

Guess what, the Archive has it right. Indeed our FAQ has an illustration comparing an Archaeopteryx with a modern bird:


Archaeopteryx and a modern bird

Notice there is quite a bit of difference between the pygostyle of the modern bird and the long tail of the Archaeopteryx as our article notes.

Now why dont you cut the bull and give me the evidence of species changing from one kind to the other because darwin said himself there must be numberless intermediate varieties, where are they? Not in the fossil record!

Your characterization of Darwin's position is strawman and not the real thing. But that notwithstanding why do you think that what Darwin wrote is some kind of holy writ for science? Do you attack science's acceptance of atoms and molecules because Dalton had false beliefs about atoms and molecules? Do you attack optics because Newton had false beliefs about optics?

In the end you bring up Darwin to avoid the issue: there are intermediate fossils -- period.

I already know what your response is going to be, you cant prove the bible, well I know that but you need to admit that evolution is also a religion that fits your lifestyle so you can tuck god into a little box and use him only when you need to.

Do you know the lifestyle of one single person who has ever contributed to this Archive?

I dont have much time to debate with you to busy educating those about the falsehoods of evolution

And not enough time to educate yourself about evolution?

And one more thing. How does the conservation of angular momentum falsify the Big Bang? Maybe you are confusing the origin of the Solar System with the Big Bang? See: Claim CE260.1: Retrograde Planets and the Big Bang.

Response: I don't know if you've noticed, but there are still several hundred millions of Homo sapiens in Africa.

Humans, and the prior species H. erectus, H. heidelbergensis, and H. neanderthalensis, all migrated out of Africa because they got to the departure points where one can walk out of Africa.

The Sahara formed when the wind patterns changed about 5000 years ago.

Response: Yes, I agree with the NABT's statement (mostly; evolution is not entirely unpredictable). "Chance" does not preclude god. There are some passages in the Bible which imply that God acts through chance events, or at least approves of them, such as the casting of lots for the parts of Israel in Joshua 18. Chance is a tricky concept to begin with. It is possible that all "chance" is simply determinism that we don't see.

Likewise, "natural" does not preclude god. In fact, to say that "natural" did preclude a creator would imply, to me, that God is not involved in nature, which would rule out God as a creator of the natural world.

Anthony Flew was temporarily convinced of the improbability of abiogenesis by an ID advocate, which caused him to accept a weak form of deism (that a god set the world in motion and has done nothing else). He later learned more about abiogenesis and admitted the invalidity of the abiogenesis argument, but apparently he remains a deist. He has never been an ID advocate. For the full story, see Antony Flew considers God--Sort of.

Response: The zealousness you see is not for evolution, but for the principles of science in general. My personal view (I suspect, but cannot claim, that others here share it) is that truth is a value worth fighting for, and that assertions backed only by conviction are not truth but hubris. Science supports the search for truth grounded in the real world, which is why I support its principles and, as a consequence, most of its findings. Most creationism opposes the very concept of science; it opposes reality-based truth in favor of conviction-based assertion, which is why I oppose that sort of creationism. You can call the support of real truth a religion if you want; to me, it is just one ideal.

I think you are mistaken about people being "zealous in their fervor to maintain the integrity and claims of evolution," too. Evolution as Darwin originally proposed it has not been maintained; it has undergone several significant changes, such as the recognition and integration of genetics, symbiotic origins of organisms, and horizontal transfer. Biologists are quite willing to find faults with evolution, as long as there is evidence for those faults. What they fervently maintain is the need for evidence.

Response: This has been covered directly in two of the TalkOrigin FAQs. The false claim made by some professional creationists that "red blood cells still visable under a microscope" had been discovered is debunked in Dino-blood and the Young Earth. More recently, researchers lead by Prof. Mary Schweitzer reported that some soft tissues could be recovered from deep within the bone of a T. rex femur. Professional creationists misunderstood, or simply misrepresented this discovery. Their false claims are debunked in Dino Blood Redux.

I hope Andrew, that you will realize that professional creationists are very unreliable sources for science.

Response: "Law" used to mean a general claim that applied without exception to all of a particular domain. For example, Newton's law of action and reaction applies to all physical objects (but not, for instance, to information, which is an imponerable). A law was also something that had a mathematical formulation.

But sometime around the end of the 19thC, scientists stopped formulating "laws" and started to formulate "rules", "models", and so on. These are still generalisations, but they do not always occur. For example, there is a rule that G pairs with C and A with T in molecular genetics, but sometimes they don't.

Late in the 19thC also, some people referred to the law of evolution. It usually meant that biological things would evolve, which is to say, not stay static. This is not a law on the scale of Newton's laws, but overall it holds pretty well. Some mathematical rules (misleadingly called theorems sometimes) of evolution have been developed in increasingly sophisticated formulations too, but we don't usually call them laws.

A law, or indeed any generalisation, explains the observed phenomena by connecting them to initial conditions. To the extent that the generalisation does this, the phenomenon is explained. Evolutionary biology explains many things - the diversity of living things and their distributions and nested similarities; why organisms in similar environments have similar forms even though they aren't closely related, and so on. These phenomena are explained by a rule that commonly descended organisms share features of their ancestors, and that similar environments cause similar adaptations. But these aren't laws so much as generalisations.

As to your second question, yes, there are some simple books and resources on evolution. SAT II Biology for Dummies looks useful. And Pharyngula has given a useful list of introductory books too.

As to your third question, that is more complex than you might realise. Some people cannot allow their most deeply held beliefs to be challeneged for sociological or psychological reasons, even if they are capable of working it through. There is a personal and social cost to revising one's beliefs that many are unwilling to pay. It may help to realise that religion provides more than a belief system, but also a social support network, and if you must believe silly things to get access to those supports, then many unconsciously choose to do just that. My two cents' worth only.

Response: I'm not sure that I understand your question.

If all you are saying is that to predict evolution or explain what has evolved we have to be here, then, well, yes. But would the things we sought to explain or predict have evolved if we did not seek to do this? Assuming our actions are not the direct cause of that evolution, then yes, they would have. The world does not depend on our ability to observe it.

But if you are suggesting that our being able to identify the "target" of a particular case of evolution is what makes that evolution possible, then I have to disagree most vehemently. That confuses knowledge of a thing with causation of a thing.

Humans evolved due to some series of evolutionary processes. We seek now to explain and understand those processes, so far as we can. Whether or not we can do this is entirely distinct from the processes themselves.

Response: The laws of physics do not determine how the universe works. Rather, our observations of how the universe works determine what we call laws of physics. Conditions at the very origin of the universe were certainly very different from how they are now, so the first law of thermodynamics, nor any other law, can be confidently applied there. Furthermore, it is possible for the universe to form from nothing without violating conservation of energy; see CF101 and the further reading suggested therein.

We do have observations of things progressing from disorder to order, so we know for an absolute fact that your interpretation of the second law of thermondynamics is invalid. The TalkOrigins archive has several articles on the subject.

Author of: Creationist Arguments: Homo erectus
Response: Meganthropus is still a mystery, as far as I know - there's no consensus as to what it is.

Whether erectus, ergaster, and georgicus are 1, 2, or 3 species is subjective, and different scientists have different opinions. It's not a big issue however; all of these specimens are fairly similar and it wouldn't cause a major rethinking of human evolution whatever is eventually decided.

Creationists do sometimes say that Homo erectus is simply part of Homo sapiens, which is a highly variable species, and Wolpoff is often claimed as support for that view, since he is the most prominent person to have called for the sinking of Homo erectus as a separate species. Wolpoff, however, is not saying that erectus is just part of the range of variation of sapiens (as creationists would like to think). He believes, as all other paleoanthropologists do, that sapiens evolved from erectus. Where he differs is that he (and some others) believe that sapiens evolved from the entire erectus population, whereas most scientists think that sapiens evolved, in an act of speciation, from a small erectus population. Wolpoff believes erectus should be classified as sapiens because there is no boundary between them and there was no act of speciation. Whether he's right or wrong, his opinion should be of no comfort to creationists. He believes that erectus is outside the anatomical range of sapiens, he doesn't believe erectus is a racial variant of sapiens, he does believe that sapiens evolved from erectus.

Response: I doubt it. The flood myths are diverse enough that they almost certainly do not have a single origin. Several of them describe the flood in terms that are good descriptions of other natural causes of floods. The Makah flood, for example, is likely inspired by a tsunami. The Mangaia Islands flood could be an exaggerated account of a hurricane storm surge. Several other myths refer explicitly to rain-swollen rivers, another common cause of floods. It is possible that some of the flood stories from the American northwest were inspired by the megafloods which went through there, but there is no way to tell now whether they were inspired by that or by smaller but much more common floods.

Response: The short version response to the Cambrian explosion, at CC300, is still pretty long. Creationists gloss over are a lot of factors that contribute to the "explosion," including
  • exaggerating the brevity of the "explosion" (it lasted 5 million years or more);
  • exaggerating how much of life was involved (it involved about a third of animal phyla and no plants, fungi, or microbes);
  • ignoring the great amount of evolution, including transitional fossils, which is observed before and after the Cambrain explosion;
  • ignoring factors such as climate change, ecological change, and the evolution of Hox genes, which can contribute to the "explosion."
