Creationist Geologic Time Scale: Should the scientific community continue to fight rear-guard skirmishes with creationists, or insist that “young-earthers” defend their model in toto? Introduction This manuscript proposes a new approach for science’s battle against the rising influence in America of pseudo-science and the Creationist movement. The framework of Creationist Bible-based earth history, focusing on Genesis and the Noachian flood, can be assembled into a single geologic time scale Figure 1 , enlarged by addition of many geologic facts, difficult for Creationists to explain. Figure 1 is an abbreviated version of the time scale outlined in the following paragraph which was redrawn and published by the American Scientist. Some of the items are so absurd that all but the most dedicated fundamentalists will see the overall picture as scientific nonsense, even bordering on humor, a most rare commodity in Creationist literature.

The assumption that the geologic column is a base from which to calibrate the C dates is not wise. With a half-life of only years, carbon dating has nothing to do with dating the geological ages! Whether by sloppiness or gross ignorance, Dr. Hovind is confusing the carbon “clock” with other radiometric “clocks.

Being ancient, the C content has long since decayed away and that makes it useful in “zeroing” laboratory instruments. It’s just one of the tricks that have been used to make the work a little more precise.

acquired trait: A phenotypic characteristic, acquired during growth and development, that is not genetically based and therefore cannot be passed on to the next generation (for example, the large.

Consider also the most popular explanation offered for the photo right , that a concretion formed around an s-era hammer as minerals precipitated out of the surrounding limestone. From Adam until Real Science Radio , in only generations! Another paper, in the American Journal of Physical Anthropology Eugenie Scott ‘s own field on High mitochondrial mutation rates , shows that one mitochondrial DNA mutation occurs every other generation, which, as creationists point out , indicates that mtEve would have lived about generations ago.

That’s not so old! As our List of Not So Old Things this web page reveals, by a kneejerk reaction evolutionary scientists assign ages of tens or hundreds of thousands of years or at least just long enough to contradict Moses’ chronology in Genesis. However, with closer study, routinely, more and more old ages get revised downward to fit the world’s growing scientific knowledge. Consistent with this observation, the May issue of National Geographic quotes the U.

Forest Service’s scientist at Mount St. Helens, Peter Frenzen, describing the canyon on the north side of the volcano. But this was cut in less than a decade. Helens, the volcanic mount, is only about 4, years old! Secular scientists default to knee-jerk, older-than-Bible-age dates. Rather than having been genetically isolated from other fish for 13, years which would make this small school of fish older than the Earth itself , according to a paper in the journal Nature, actual measurements of mutation rates indicate that the genetic diversity of these Pupfish could have been generated in about years, give or take a few.

Previously, seven sedimentary layers in Wisconsin had been described as taking a million years to form.

Cities like Omaha, home to the Henry Doorly Zoo deemed one of the best in the nation , are historical and cultural centers. Here are the best Nebraska places to visit. Omaha Omaha is a lively city that is constantly reimagining itself. From the downtown Old Market area with its quaint shops and weekly farmers market to the modern s-curve Bob Kerrey Pedestrian Bridge, there is always something to see and do.

Grand Island boasts a wide range of activities and attractions as well as seasonal events throughout the year. Visitors can enjoy everything from splashing around at the Island Oasis Water Park to looking into the past at the Stuhr Museum of the Prairie Pioneer.

A study of biology includes the study of the chemical basis of living organisms, DNA. Other related sciences include microbiology and organic chemistry. The word science comes from a Latin word scientica, which means knowledge, or information. Science is a process of systematically gathering detailed information and gaining exact knowledge. We do not know all the “life” information secrets but we are learning more every day.

The three biological life cycle s, are; Zygotic meiosis, Sporic meiosis, and Gametic meiosis, Amoeba – one basic life form. Amoebas and there are many different kinds feed by phagocytosis the engulfing and ingesting of foreign particles or waste matter by phagocytes –they flow around their prey usually a smaller cell and engulf it. Organism that eat other organisms are usually called “consumers”.

Walter Brown’s “Hydroplate” Flood Model Doesn’t Hold Water

Volatile-Rich Planet Loading the player MESSENGER measurements have revealed that Mercury is surprisingly abundant in volatile elements that evaporate at moderately high temperatures, ruling out many of the models for its formation and early history that had been proposed before the mission. Because potassium is much more volatile than thorium, the ratio of the abundances of these two elements is a sensitive measure of thermal processes that fractionate elements by volatility.

For Mercury, as seen in the first graph, this ratio is similar to that for other terrestrial planets at greater distances from the Sun but significantly higher than that for the Moon, which lost potassium during the giant impact that led to its formation. Relatively high abundances of other volatile elements, including sulfur right side of the animation , sodium, and chlorine, provide further evidence that Mercury is volatile-rich.

Examines the last two decades’ advances in analyzing and understanding the formation of natural diamonds, and their relation to the earth’s formation.

This has changed over the past few decades because of the dramatic advances in digital imaging technologies and computer power. One of the best examples of this was the computer artistry of Ray Downing, whose digital re-creation of Jesus based on the Shroud was documented in “The Real Face of Jesus” program that appeared on the History Channel. In the past few years, digital artists around the world have been able to render their own interpretations of how Jesus may have appeared based on the Shroud and these show up from time to time on the internet.

However, throughout all those years, not one artist has attempted to create an interpretation of what Mary, Mother of Jesus looked like based on the Shroud image. Until now, that is. In July of my good friends Bill and Belenna Lauto directed me to the website of digital artist Dean Packwood in Taupo, New Zealand and shared his beautiful, photorealistic rendition of Mary, Mother of Jesus with me.

Dean chose the Shroud of Turin image as the structural basis for his truly beautiful, completely digital artwork and I wanted to share it with you. So I sent Dean a request for permission to include his painting here on our website and he graciously agreed to share it with us. What is most exciting to watch is the time-lapse video 3:

Isochron Dating By Chris Stassen The article is well illustrated and well written. There is an introduction to the generic problem of radiometric dating, but this article concentrates on one well established method called the “isochron method”.

Genesis Evolution is a fact and a theory. One is observed today in the lab and in the natural environment. The other is more of a philosophical if not religious viewpoint. Changes do occur within the kinds of animals, and this is not evolution but instead adaptive variation. What is not observed is the divergence from a common ancestor that, for example, created the chimps and the humans.

That common ancestor is supposedly ape-like, but the alleged divergence was not, nor can it ever be, observed, tested, or validated. The past happened in the past; you cannot watch it happen now. All we can see today is chimps, apes, baboons, and the other primate-type species being related to the primate kind; humans have their variations race, etc.

All experiments have only shown the variation with kinds. It has not shown the ape-like ancestor diverging into chimps and humans. Nor do experiments show a water-dwelling creature become amphibious and then become land-dwelling. These things are supposed to have happened in the unobserved past. If it is not observable and testable, it is not science.

A phenotypic characteristic, acquired during growth and development, that is not genetically based and therefore cannot be passed on to the next generation for example, the large muscles of a weightlifter. Any heritable characteristic of an organism that improves its ability to survive and reproduce in its environment. Also used to describe the process of genetic change within a population, as influenced by natural selection.

An ice core is a core sample that is typically removed from an ice sheet or a high mountain the ice forms from the incremental buildup of annual layers of snow, lower layers are older than upper, and an ice core contains ice formed over a range of years.

There are lots of ways to guesstimate ages, and geologists knew the earth was old a long time ago and I might add that they were mostly Christian creationist geologists. But they didn’t know how old. Radiometric dating actually allows the measurement of absolute ages, and so it is deadly to the argument that the earth cannot be more than 10, years old. Radiometric methods measure the time elapsed since the particular radiometric clock was reset.

Radiocarbon dating, which is probably best known in the general public, works only on things that were once alive and are now dead. It measures the time elapsed since death, but is limited in scale to no more than about 50, years ago. Generally applied to igneous rocks those of volcanic origin , they measure the time since the molten rock solidified. If that happens to be longer than 10, years, then the idea of a young-Earth is called into question. If that happens to be billions of years, then the young-Earth is in big trouble.

As of January, , The oldest rocks found on earth are 4. This is reported in the paper Priscoan 4. Williams; Contributions to Mineralogy and Petrology 1: The previous record was 3. The putative age of the Earth, about 4, , , years is based on the radiometrically measured age of meteorites, and is also about , , years older than the oldest rocks.
