    Following the evidence, this disproves common ancestry

    I'm sure you can point us to at least one peer-reviewed article, written by an expert in a relevant field, and published in a reputable scientific journal, that supports this claim?


    Or is it just wishful thinking by people who don't really know what they're talking about?

    My point was not to claim that God created the world via evolution or even directly. Neither was my issue about whatever evidence you may or may not "believe" in.

    My point is that your claiming to be a theist while claiming God did not create life via evolution presumes limits on your definition of God.

    Making God fit into such definite limitations is an attempt to create an idol. You don't have to build a literal golden calf to make God into a man-made image. You can do so by doctrine, saying that God can do such and such, but God cannot do this or does not do that. Humans who create definitions like "God does not create via evolution" are creating a god for themselves no different than the idolatry Christians claim to detest. How can a mortal have a complete comprehension of what God can and cannot and does not do in reference to creating life?

    Answer me this: If there is a God, why can't God create by means of evolution? Why is the only possibility the one you are stating?

    How do you know that your views of God and how God created life are correct? Even the Governing Body of Jehovah's Witnesses claims that that they are not inspired and have made mistakes and that Christ never promised "perfect" spiritual food "at the proper time." If this is so, how can you guarantee that your view that God did not create the world by evolution is free of imperfections or complete?

    And where does evolution teach there is no God? Charles Darwin was honored by the Church of England with a burial in Westminster Abbey for his achievements in this work. While Darwin was an agnostic, he never taught there was no possibility of God, and mainstream Christianity even embraced his work as offering the scientific answer to how life came to be. The Bishop of Carlisle stated in Darwin's memorial funeral sermon: "It would have been unfortunate if anything had occurred to give weight and currency to the foolish notion which some have diligently propagated, but for which Mr. Darwin was not responsible, that there is a necessary conflict between a knowledge of Nature and a belief in God."

    I find that most people who take sides on this issue have never read Origin of Species or even seen a copy. Have you? Do you know what Darwin actually said? Most who have an opinion have never read Darwin's own notes or his views on how what he discovered applied to theological concepts. Most only know what they do from secondhand sources, or just through blurbs, cited quotes, or watching a television program or two. Suddenly such people believe they have enough information to form an opinion. Some people will even read books on the subject but still never the actual information written by Darwin himself. The issue of evolution is not one about whether there is a God or not, so it does only harm to the religionist who fails to educate themselves on the matter.

    I think TWM is referring to a book called 'Evolution: A theory in crisis' written in 1985 by M.J. Denton. In this book this biochemist (I think) makes the same suggestions as TWM is now doing some 30 years later.

    As usual we see this type of evolutionary critic releasing books for those who most likely share this viewpoint already.

    This critique from talkorigins.org explains why M.J Denton is wrong; there is also a second review of his book linked on that page that makes for good reading to those interested.

    To Finklestien

    ‘… we are not even authorized to consider the exceptional case of Archaeopteryx as a true link. By link, we mean a necessary stage of transition between classes such as reptiles and birds, or between smaller groups. An animal displaying characters belonging to two different groups cannot be treated as a true link as long as the intermediary stages have not been found, and as long as the mechanism of transition remains unknown.’ [Human Destiny] Evolutionist Lecomte du Noüy

    ‘Since Archaeopteryx occupies an isolated position in the fossil record, it is impossible to tell whether the animal gave rise to more advanced fliers …’ [Vertebrate History: Problems in Evolution] evolutionist Barbara Stahl

    ‘The origin of birds is largely a matter of deduction. There is no fossil of the stages through which the remarkable change from reptile to bird was achieved.’ [Biology and Comparative Physiology of Birds] evolutionist W.E. Swinton

    The above has been known for many years and the evolutionist still argues that the Archaeopteryx is a transitional species. But that is not all. A bird which is unquestionably a true bird has been found which dates (by the evolutionists’ own methods) at some 60 million years older than Archaeopteryx. This was announced in Science-News 112:198, Sep. 1977) The find was assessed as above by Dr James Jensen of Brigham Young University. The article also quotes Prof. John Ostrom of Yale:

    ‘… we must now look for the ancestors of flying birds in a period of time much older than that in which Archaeopteryx lived.’

    Further there is nothing in the fossil record before or after Archaeopteryx, but the evolutionist still peddles it as a transitional species.

    You commented earlier about honesty. In all the years I have been discussing worldviews, the most dishonest are the evolutionist. They would lie before admitting to anything. Again I envy your faith, I could never come close to believing in ‘Once upon a time” tales.

    To be fair, considering you are posting ideas that were debunked those 30 odd years ago when they were first asserted, you should be thankful of any attention and not dismissive of it as you are with Simon's contribution.

    Also, you keep alluding that faith is needed to accept evolution. That statement tells me all I need to know about the level of your understanding of the work involved in the natural sciences...

    Why? Are you now incapable of processing information? The evolutionist love to point to Cytochrome c as proof of common ancestry because we all have it. But if that is true then the percentage of difference should increase as the evolutionary hierarchy widens. But it does not. For example

    Compare Rhodospirillum rubrum [bacteria] and Eucaryotic organisms. Percentage of difference.

    Horse 64%, Pigeon 64%, Tuna 65%, Silk worm 65%, Wheat 66%, Yeast 69%

    Only a four percent difference between Rhodospirillum rubrum and Horse, and Rhodospirillum rubrum and yeast. The difference between yeast and horse should at least be proportional to what I am physically observing., and I am not. What this points to is that all living creatures appeared on the fossil record at about the same time.

    Your joking right ?


    Using the scientific method in time dating fossils there has to be collaborative support with other considerations like geological dating of rock/soil where the fossil is found.

    Here of some of the well-tested methods of dating used in the study of early humans:

    • Potassium-argon dating, Argon-argon dating, Carbon-14 (or Radiocarbon), and Uranium series. All of these methods measure the amount of radioactive decay of chemical elements; the decay occurs in a consistent manner, like a clock, over long periods of time.
    • Thermo-luminescence, Optically stimulated luminescence, and Electron spin resonance. All of these methods measure the amount of electrons that get absorbed and trapped inside a rock or tooth over time.
    • Paleomagnetism. This method compares the direction of the magnetic particles in layers of sediment to the known worldwide shifts in Earth’s magnetic field, which have well-established dates using other dating methods.
    • Biochronology. Since animal species change over time, the fauna can be arranged from younger to older. At some sites, animal fossils can be dated precisely by one of these other methods. For sites that cannot be readily dated, the animal species found there can be compared to well-dated species from other sites. In this way, sites that do not have radioactive or other materials for dating can be given a reliable age estimate.
    • Molecular clock. This method compares the amount of genetic difference between living organisms and computes an age based on well-tested rates of genetic mutation over time. Since genetic material (like DNA) decays rapidly, the molecular clock method can’t date very old fossils. It’s mainly useful for figuring out how long ago living species or populations shared a common ancestor, based on their DNA.

    Determining the numerical age of rocks and fossils

    Unlike relative dating methods, absolute dating methods provide chronological estimates of the age of certain geological materials associated with fossils, and even direct age measurements of the fossil material itself. To establish the age of a rock or a fossil, researchers use some type of clock to determine the date it was formed. Geologists commonly use radiometric dating methods, based on the natural radioactive decay of certain elements such as potassium and carbon, as reliable clocks to date ancient events. Geologists also use other methods - such as electron spin resonance and thermoluminescence, which assess the effects of radioactivity on the accumulation of electrons in imperfections, or "traps," in the crystal structure of a mineral - to determine the age of the rocks or fossils.

    All elements contain protons and neutrons, located in the atomic nucleus, and electrons that orbit around the nucleus (Figure 5a). In each element, the number of protons is constant while the number of neutrons and electrons can vary. Atoms of the same element but with different number of neutrons are called isotopes of that element. Each isotope is identified by its atomic mass, which is the number of protons plus neutrons. For example, the element carbon has six protons, but can have six, seven, or eight neutrons. Thus, carbon has three isotopes: carbon 12 (12C), carbon 13 (13C), and carbon 14 (14C) (Figure 5a).

    Radioactive isotopes and how they decay through time.
    Figure 5: Radioactive isotopes and how they decay through time.
    (a) Carbon has three isotopes with different numbers of neutrons: carbon 12 (C12, 6 protons + 6 neutrons), carbon 13 (C13, 6 protons + 7 neutrons), and carbon 14 (C14, 6 protons + 8 neutrons). C12 and C13 are stable. The atomic nucleus in C14 is unstable making the isotope radioactive. Because it is unstable, occasionally C14 undergoes radioactive decay to become stable nitrogen (N14). (b) The radioactive atoms (parent isotopes) in any mineral decay over time into stable daughter isotopes. The amount of time it takes for half of the parent isotopes to decay into daughter isotopes is known as the half-life of the radioactive isotope.

    Most isotopes found on Earth are generally stable and do not change. However some isotopes, like 14C, have an unstable nucleus and are radioactive. This means that occasionally the unstable isotope will change its number of protons, neutrons, or both. This change is called radioactive decay. For example, unstable 14C transforms to stable nitrogen (14N). The atomic nucleus that decays is called the parent isotope. The product of the decay is called the daughter isotope. In the example, 14C is the parent and 14N is the daughter.

    Some minerals in rocks and organic matter (e.g., wood, bones, and shells) can contain radioactive isotopes. The abundances of parent and daughter isotopes in a sample can be measured and used to determine their age. This method is known as radiometric dating. Some commonly used dating methods are summarized in Table 1.

    The rate of decay for many radioactive isotopes has been measured and does not change over time. Thus, each radioactive isotope has been decaying at the same rate since it was formed, ticking along regularly like a clock. For example, when potassium is incorporated into a mineral that forms when lava cools, there is no argon from previous decay (argon, a gas, escapes into the atmosphere while the lava is still molten). When that mineral forms and the rock cools enough that argon can no longer escape, the "radiometric clock" starts. Over time, the radioactive isotope of potassium decays slowly into stable argon, which accumulates in the mineral.

    The amount of time that it takes for half of the parent isotope to decay into daughter isotopes is called the half-life of an isotope (Figure 5b). When the quantities of the parent and daughter isotopes are equal, one half-life has occurred. If the half life of an isotope is known, the abundance of the parent and daughter isotopes can be measured and the amount of time that has elapsed since the "radiometric clock" started can be calculated.

    For example, if the measured abundance of 14C and 14N in a bone are equal, one half-life has passed and the bone is 5,730 years old (an amount equal to the half-life of 14C). If there is three times less 14C than 14N in the bone, two half lives have passed and the sample is 11,460 years old. However, if the bone is 70,000 years or older the amount of 14C left in the bone will be too small to measure accurately. Thus, radiocarbon dating is only useful for measuring things that were formed in the relatively recent geologic past. Luckily, there are methods, such as the commonly used potassium-argon (K-Ar) method, that allows dating of materials that are beyond the limit of radiocarbon dating (Table 1).

    Table 1. Comparison of commonly used dating methods.

    Radiation, which is a byproduct of radioactive decay, causes electrons to dislodge from their normal position in atoms and become trapped in imperfections in the crystal structure of the material. Dating methods like thermoluminescence, optical stimulating luminescence and electron spin resonance, measure the accumulation of electrons in these imperfections, or "traps," in the crystal structure of the material. If the amount of radiation to which an object is exposed remains constant, the amount of electrons trapped in the imperfections in the crystal structure of the material will be proportional to the age of the material. These methods are applicable to materials that are up to about 100,000 years old. However, once rocks or fossils become much older than that, all of the "traps" in the crystal structures become full and no more electrons can accumulate, even if they are dislodged.

    Using paleomagnetism to date rocks and fossils

    The Earth is like a gigantic magnet. It has a magnetic north and south pole and its magnetic field is everywhere (Figure 6a). Just as the magnetic needle in a compass will point toward magnetic north, small magnetic minerals that occur naturally in rocks point toward magnetic north, approximately parallel to the Earth's magnetic field. Because of this, magnetic minerals in rocks are excellent recorders of the orientation, or polarity, of the Earth's magnetic field.

    The earth’s magnetic field can be measured to determine the polarity of a rock sample.
    Figure 6: The earth’s magnetic field can be measured to determine the polarity of a rock sample.
    (a) The earth is surrounded by a magnetic field generated by the magnetism in the core of the earth. Small magnetic grains in rocks will orient themselves to be parallel to the direction of the magnetic field pointing towards the north pole. (b) The geomagnetic polarity time scale shows how the polarity of the earth’s magnetic field has changed through time. Black bands indicate times of normal polarity and white bands indicate times of reversed polarity.

    Through geologic time, the polarity of the Earth's magnetic field has switched, causing reversals in polarity. The Earth's magnetic field is generated by electrical currents that are produced by convection in the Earth's core. During magnetic reversals, there are probably changes in convection in the Earth's core leading to changes in the magnetic field. The Earth's magnetic field has reversed many times during its history. When the magnetic north pole is close to the geographic north pole (as it is today), it is called normal polarity. Reversed polarity is when the magnetic "north" is near the geographic south pole. Using radiometric dates and measurements of the ancient magnetic polarity in volcanic and sedimentary rocks (termed paleomagnetism), geologists have been able to determine precisely when magnetic reversals occurred in the past. Combined observations of this type have led to the development of the geomagnetic polarity time scale (GPTS) (Figure 6b). The GPTS is divided into periods of normal polarity and reversed polarity.

    Geologists can measure the paleomagnetism of rocks at a site to reveal its record of ancient magnetic reversals. Every reversal looks the same in the rock record, so other lines of evidence are needed to correlate the site to the GPTS. Information such as index fossils or radiometric dates can be used to correlate a particular paleomagnetic reversal to a known reversal in the GPTS. Once one reversal has been related to the GPTS, the numerical age of the entire sequence can be determined.

    Summary

    Using a variety of methods, geologists are able to determine the age of geological materials to answer the question: "how old is this fossil?" Relative dating methods are used to describe a sequence of events. These methods use the principles of stratigraphy to place events recorded in rocks from oldest to youngest. Absolute dating methods determine how much time has passed since rocks formed by measuring the radioactive decay of isotopes or the effects of radiation on the crystal structure of minerals. Paleomagnetism measures the ancient orientation of the Earth's magnetic field to help determine the age of rocks.
