How does young earth creationism handle the evidence for millions of years in the fossil record

This past week, Buffalo and Watertown, New York, registered their coldest week in recorded weather history. Boston, too, is set to tie its record of seven straight days with temperatures remaining below 20 degrees, reports Weather. Flint, Michigan, set its all-time record-low temperature for December of 18 degrees below zero last Thursday morning. North American cities too numerous to mention have been setting records for daily low temperatures, as the gelid weather wave shows its impressive staying power. For instance, the National Weather Service reported a temperature of minus 15 F in Omaha on Sunday, breaking a record low dating back to So what is going on? During the summer period, mainstream media offer an ongoing stream of reports of how climate change is causing higher temperatures and severe weather, yet when temperatures drop to record lows in wintertime, they write them off as normal cyclical weather phenomena. As a result, more freezing Arctic air is swooping further south, he proposes. In other words, all weather behavior—whether colder or warmer—becomes a confirmation that manmade global warming is real.

How does young earth creationism handle the evidence for millions of years in the fossil record? The trick with interpreting the fossil record is that most paleontologists also subscribe an atheistic version of evolution. They interpret the fossil record in terms of that particular worldview, inspect the interpretation, and note that it confirms the theory, which is more than a little circular.

So, how do we know how old a fossil is? There are two main methods determining a fossils age, relative dating and absolute dating. Relative dating is used to determine a fossils approximate age by comparing it to similar rocks and fossils of known ages. Absolute dating is used to determine a precise age of a fossil by using radiometric dating to measure the decay of isotopes, either within the fossil or more often the rocks associated with it. Relative Dating The majority of the time fossils are dated using relative dating techniques.

Using relative dating the fossil is compared to something for which an age is already known. For example if you have a fossil trilobite and it was found in the Wheeler Formation.

January Fossils provide a record of the history of life. Smith is known as the Father of English Geology. Our understanding of the shape and pattern of the history of life depends on the accuracy of fossils and dating methods. Some critics, particularly religious fundamentalists, argue that neither fossils nor dating can be trusted, and that their interpretations are better.

Other critics, perhaps more familiar with the data, question certain aspects of the quality of the fossil record and of its dating.

Dating the Fossil Record Activity Name Per. You have received nine rock samples from a paleontologist in California. Your job is to arrange the samples in order from oldest to youngest according to their fossil content and to determine their relative ages using the process of relative dating.

Tweet The Eras The layers of the fossil record are divided into three main eras: Paleozoic, Mesozoic, and Cenozoic. These eras are characterized by different kinds of fossils. The Paleozoic era is known for marine life, amphibians, and reptiles. In this layer of the fossil record we find extensive coal beds made up mostly of extinct plants such as giant horsetails, ferns, seedless plants, and club mosses. The Mesozoic era is known for its dinosaurs and many other reptiles.

This era is associated with massive extinctions. In a catastrophic flood model, this era is the end of the flood period, before the continents reemerged out of the waters that covered the earth. The Cenozoic era is known for mammals and birds. Cenozoic plants are similar to the species that exist today. The type of fossil found in the various layers changes as one goes up the geological column, from invertebrates, fish, amphibians, and reptiles, to the mammals and birds in the upper layers.

This order in the fossil record is one of the prime evidences used by scientists to establish evolution as a fact. However, the sequence is not from simple organisms to complex organisms as evolutionists suggest, but rather from marine sessile to free swimming to land dwelling.

It could be likened to a movie recording the history of life across nearly four billion years of geological time. The problem is that only a small fraction of the frames are preserved, and those that have been preserved have often been chronologically scrambled. Viewed in this way, reconstituting the movie seems intractable, and yet science has done so. Frames are still missing, but the intricate, interwoven plots are largely revealed.

The process of descent with modification through natural selection, or evolution , that Darwin published in the mid 19th century became the framework for many scientific disciplines to use fossils to recover the missing frames and their ordering in time.

The fossil record is an incomplete history of life because not everything fossilizes. Explanation: For the fossil record to be a complete reference for past life, we’d need to have a record for every organism that ever lived on the planet.

See Article History Fossil record, history of life as documented by fossils , the remains or imprints of the organisms from earlier geological periods preserved in sedimentary rock. In a few cases the original substance of the hard parts of the organism is preserved, but more often the original components have been replaced by minerals deposited from water seeping through the rock. Occasionally the original material is simply removed, while nothing is deposited in its place; in this case, all that remains is a mould of the shape of the plant or animal.

A brief treatment of the fossil record follows. For full treatment, see geochronology. Wilson Department of Geology, The College of Wooster In some places, such as the Grand Canyon in Arizona, it is possible to recognize a great thickness of nearly horizontal strata representing the deposition of sediment on the seafloor over many hundreds of millions of years. It is often observed that each layer in such a sequence contains fossils that are distinct from those of the layers that are above and below it.

In such sequences of layers in different places, the same, or similar, fossil floras or faunas occur in the identical order. By comparison of overlapping sequences it is possible to build up a continuous record of faunas or floras that have progressively more in common with present-day life forms as the top of the sequence is approached. Study of the fossil record has provided important information for at least three different purposes.

The progressive changes observed within an animal group are used to describe the evolution of that group. In general, but not always, successive generations tend to change morphologically in a particular direction e. Fossils also provide the geologist a quick and easy way of assigning an age to the strata in which they occur.

The precision with which this may be done in any particular case depends on the nature and abundance of the fauna:

Importance of Fossils

Gorilla skulls like this one aren’t common in the wild, but Bigfoot bones are unheard of. One find could prove Bigfoot is real once and for all. If not bones and bodies, at the very least there should be evidence of a North American Ape in the fossil record. There are no confirmed Bigfoot bones or fossils, of course, and the skeptics have a point. Biology is a science, and science is based on fact. Without compelling physical evidence no biologist or paleontologist would ever make the claim that Bigfoot does, or did, exist.

The Fossil Record Science Games. The fossil record consists of every fossil ever discovered on Earth. However, it only represents a small fraction of the organisms that have ever lived on our planet. radiocarbon dating, relative age, absolute age, radioactive decay, isotope, stratigraphy, cast.

February Learn how and when to remove this template message The principle of faunal succession, also known as the law of faunal succession, is based on the observation that sedimentary rock strata contain fossilized flora and fauna , and that these fossils succeed each other vertically in a specific, reliable order that can be identified over wide horizontal distances.

A fossilized Neanderthal bone will never be found in the same stratum as a fossilized Megalosaurus , for example, because neanderthals and megalosaurs lived during different geological periods , separated by many millions of years. This allows for strata to be identified and dated by the fossils found within. This principle, which received its name from the English geologist William Smith , is of great importance in determining the relative age of rocks and strata.

Evolution explains the observed faunal and floral succession preserved in rocks. Faunal succession was documented by Smith in England during the first decade of the 19th century, and concurrently in France by Cuvier with the assistance of the mineralogist Alexandre Brongniart. Archaic biological features and organisms are succeeded in the fossil record by more modern versions. For instance, paleontologists investigating the evolution of birds predicted that feathers would first be seen in primitive forms on flightless predecessor organisms such as feathered dinosaurs.

This is precisely what has been discovered in the fossil record: In Cenozoic strata, fossilized tests of foraminifera are often used to determine faunal succession on a refined scale, each biostratigraphic unit biozone being a geological stratum that is defined on the basis of its characteristic fossil taxa.

An outline microfaunal zonal scheme based on both foraminifera and ostracoda was compiled by M.

CREATION / EVOLUTION: The Fossil Record

Everything Worth Knowing About Scientific Dating Methods This dating scene is dead. The good dates are confirmed using at least two different methods, ideally involving multiple independent labs for each method to cross-check results. Sometimes only one method is possible, reducing the confidence researchers have in the results. Methods fall into one of two categories:

Life Science: Dating the Fossil Record ActivityName Per.. You have received nine rock samples from a paleontologist in California. Your job is to arrange the samples in order from oldest to youngest according to their fossil content and to determine their relative ages using the process of relative dating.

Geological Time and the Rock Record The rock record of interest to students of Geology is dominantly the record of sedimentary rocks. Igneous rocks include volcanic rocks, which can and do cover large areas of Earth’s surface. But they do not in general have many fossils in them. Occasionally a lava flow may overwhelm and preserve organisms as fossils, but that is rare. Volcanic ash beds are important in dating other rock layers, however, as we shall see.

Sedimentary rocks are laid down and accumulated on the surface of the earth under normal temperatures and pressures. The particles that make up the sediments – clays, silts, sand, pebbles, and boulders, are formed from pre-existing rocks by weathering and are then transported by various agents of erosion until they are finally deposited in a permanent resting place. Molded then by further sedimentary layers deposited on top of them, sediments are compressed, so that any water that lies between the grains is squeezed out in dewatering, often leaving behind any minerals it contained in solution to form cements that bind the sediments together.

Eventually the squeezing and cementation allows one to say that a rock has formed from the original sediment. The process is called lithification. If in the process, organisms or traces of organisms have been buried along with the sedimentary particles, then those organisms may survive well enough to be exposed, recognized, and collected as fossils. We will return to the process of fossilization. We need to be able to place any fossils we find in the context of the rocks we find them in. The evidence allows us to do two different interpretations.

Human Fossils

Fossil Record The cyanobacteria have an extensive fossil record. The oldest known fossils, in fact, are cyanobacteria from Archaean rocks of western Australia, dated 3. This may be somewhat surprising, since the oldest rocks are only a little older: Cyanobacteria are among the easiest microfossils to recognize.

A fossil record is a collection of fossils that document the history of life on Earth. Paleontologists use the location of fossils to preform relative dating to learn about the history of life and.

Such time determinations are made and the record of past geologic events is deciphered by studying the distribution and succession of rock strata, as well as the character of the fossil organisms preserved within the strata. Grand Canyon wall cutaway diagram showing the ages of the rock layers. According to a long-standing principle of the geosciences, that of superposition, the oldest layer within a sequence of strata is at the base and the layers are progressively younger with ascending order.

The relative ages of the rock strata deduced in this manner can be corroborated and at times refined by the examination of the fossil forms present. The tracing and matching of the fossil content of separate rock outcrops i. Fossils help geologists establish the ages of layers of rock. In this diagram, sections A and B represent rock layers miles km apart. Their ages can be established by comparing the fossils in each layer.

Radiometric dating has provided not only a means of numerically quantifying geologic time but also a tool for determining the age of various rocks that predate the appearance of life-forms. Preserved in these rocks is the complex record of the many transgressions and regressions of the sea, as well as the fossil remains or other indications of now extinct organisms and the petrified sands and gravels of ancient beaches, sand dunes, and rivers.

Statue of seated man said to be Herodotus; in the Louvre, Paris. Xenophanes of Colophon ? These early observations and interpretations represent the unstated origins of what was later to become a basic principle of uniformitarianism , the root of any attempt at linking the past as preserved in the rock record to the present.

Radiometric Dating and the Geological Time Scale

In this article I will examine an issue that is sometimes thought to be a problem for the theory of evolution: Please note that the previous article is a prerequisite for understanding properly the present one. For example, even when we have every reason to suspect that species A of a kind of squirrels evolved into species B of a different kind of squirrels, we cannot find a smooth transition of fossils from A to B, but a rather abrupt appearance of B at some point in time.

How the gaps are explained by evolution Some people who are typically not biologists think that the gaps in the fossil record present a problem to the theory of evolution, because they do not show a gradual and smooth change of one species changing into another. Also, Georges Cuvier had supported the theory of catastrophism, a consequence of which concluded that species appear relatively suddenly after catastrophic geological events.

We would like to show you a description here but the site won’t allow us.

These formations may have resulted from carcass burial in an anoxic environment with minimal bacteria, thus slowing decomposition. Stromatolites Lower Proterozoic Stromatolites from Bolivia , South America Stromatolites are layered accretionary structures formed in shallow water by the trapping, binding and cementation of sedimentary grains by biofilms of microorganisms , especially cyanobacteria. While older, Archean fossil remains are presumed to be colonies of cyanobacteria , younger that is, Proterozoic fossils may be primordial forms of the eukaryote chlorophytes that is, green algae.

One genus of stromatolite very common in the geologic record is Collenia. The earliest stromatolite of confirmed microbial origin dates to 2. The most widely supported explanation is that stromatolite builders fell victims to grazing creatures the Cambrian substrate revolution , implying that sufficiently complex organisms were common over 1 billion years ago. Factors such as the chemistry of the environment may have been responsible for changes.
