My friends call me Ape Jaw Evan. Click here to read about me and other media myths, frauds, and lies. The Theory of Evolution is not a scientific law or a law of biology. Failure to meet only one challenge proves the law is wrong. This web page will prove that the Theory of Evolution fails many challenges, not simply one. The Theory of Evolution will never become a law of science because it is wrought with errors. This is why it is called a theory, instead of a law. The process of natural selection is not an evolutionary process.
But modern conventional geological science, which is accepted by almost all geologists, is a “hybrid combination” proposing that slow uniformitarian processes produced most features, but fast catastrophic events produced some features, as explained by Mark Isaak and Greg Neyman. Scientific Methods and Logical Evaluations This page begins by asking, Can we use historical science to get reliable information about the history of nature?
Usually, advocates of a young earth say NO.
Left and right, archaeologists are radiocarbon dating objects: fossils, documents, shrouds of Turin. They do it by comparing the ratio of an unstable isotope, carbon, to the normal, stable.
Important We believe any unbiased reader will realize that we were fair with our treatment of the two models in the table above. Yet, although the theory of evolution matches the facts in some cases, evolution is still an unproven theory. By now, you may believe it should be your first choice also. Unlike many others that preceded us, we attempted to find a clear defense of evolution for two reasons: To keep from being accused of bias.
To keep from making claims that someone could refute later. Even though there are a great number of claims in books and on the Internet, we could find no scientific, testable facts that support the theory of evolution.
How dating methods work
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.
Amino acid dating accuracy of carbon dating fossils acid dating has an important attribute with carbon 14 most other dating mechanisms date the rock surrounding fossils, both amino acid and carbon 14 dating methods, date the actual fossil itself.
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. Cyanobacteria as well as extremophile Gammaproteobacteria are thought to be largely responsible for increasing the amount of oxygen in the primeval earth’s atmosphere through their continuing photosynthesis.
Cyanobacteria use water , carbon dioxide and sunlight to create their food. A layer of mucus often forms over mats of cyanobacterial cells. In modern microbial mats, debris from the surrounding habitat can become trapped within the mucus, which can be cemented by the calcium carbonate to grow thin laminations of limestone. These laminations can accrete over time, resulting in the banded pattern common to stromatolites.
The domal morphology of biological stromatolites is the result of the vertical growth necessary for the continued infiltration of sunlight to the organisms for photosynthesis.
Accuracy of Fossils and Dating Methods
The science of studying fossils A palaeontologist at work in the laboratory The search for fossils begins with geological surveys. Some areas are more likely to yield fossils than others, and researchers normally concentrate their efforts on regions that have good, fossil-bearing rock such as the dolomitic limestone of the Cradle of Humankind and the ancient lake beds of East Africa. But a good measure of luck is also needed sometimes, as was the case in many of the Cradle of Humankind sites, which were first explored by miners.
Hundreds of palaeontological sites in South Africa have been exposed by miners. But sadly, many have been destroyed in the mining process.
Acknowledgements Introduction his document discusses the way radiometric dating and stratigraphic principles are used to establish the conventional geological time scale. It is not about the theory behind radiometric dating methods, it is about their application, and it therefore assumes the reader has some familiarity with the technique already refer to “Other Sources” for more information. As an example of how they are used, radiometric dates from geologically simple, fossiliferous Cretaceous rocks in western North America are compared to the geological time scale.
To get to that point, there is also a historical discussion and description of non-radiometric dating methods. A common form of criticism is to cite geologically complicated situations where the application of radiometric dating is very challenging. These are often characterised as the norm, rather than the exception. I thought it would be useful to present an example where the geology is simple, and unsurprisingly, the method does work well, to show the quality of data that would have to be invalidated before a major revision of the geologic time scale could be accepted by conventional scientists.
Geochronologists do not claim that radiometric dating is foolproof no scientific method is , but it does work reliably for most samples. It is these highly consistent and reliable samples, rather than the tricky ones, that have to be falsified for “young Earth” theories to have any scientific plausibility, not to mention the need to falsify huge amounts of evidence from other techniques.
Dating Fossils in the Rocks
Slowly and painstakingly, geologists have assembled this record into the generalized geologic time scale shown in Figure 1. This was done by observing the relative age sequence of rock units in a given area and determining, from stratigraphic relations, which rock units are younger, which are older, and what assemblages of fossils are contained in each unit.
Using fossils to correlate from area to area, geologists have been able to work out a relative worldwide order of rock formations and to divide the rock record and geologic time into the eras, periods, and epochs shown in Figure 1. The last modification to the geologic time scale of Figure 1 was in the s, before radiometric dating was fully developed, when the Oligocene Epoch was inserted between the Eocene and the Miocene.
Although early stratigraphers could determine the relative order of rock units and fossils, they could only estimate the lengths of time involved by observing the rates of present geologic processes and comparing the rocks produced by those processes with those preserved in the stratigraphic record. With the development of modern radiometric dating methods in the late s and s, it was possible for the first time not only to measure the lengths of the eras, periods, and epochs but also to check the relative order of these geologic time units.
Absolute dating is used to determine a precise age of a rock or fossil through radiometric dating methods. This uses radioactive minerals that occur in rocks and fossils almost like a geological clock.
Vocabulary This diagram shows a selection of rock layers, or stratigraphic columns, from the Koobi Fora geologic formation on the eastern shore of Lake Turkana in Kenya. This area is a ridge of sedimentary rock where researchers have found more than 10, fossils, both human and other hominins, since These fossils aid the scientific investigation of human evolution. Lake Turkana has a geologic history that favored the preservation of fossils.
Scientists suggest that the lake as it appears today has only been around for the past , years. The current environment around Lake Turkana is very dry. Over the course of time, though, the area has seen many changes. The climate of the region was once more humid , which may have been favorable for early humans and hominins to have flourished there. All lakes, rivers, and streams carry sediment such as soil, sand, and volcanic matter. This sediment eventually settles on the bottom of lake beds or deposits at the mouth of rivers in an alluvial fan.
This process of material deposition and erosion as well as the rise and fall in the lake levels due to environmental changes slowly added layers to the geologic record found in the Turkana Basin. Over time the sediment solidified into rock.
Everything Worth Knowing About … Scientific Dating Methods
Indeed, this literature abounds with direct and indirect references to a Deity or Creator, and citations of the Bible are not uncommon for example, 22 , 77 , 90 , 91 , 96 , 97 , 99 , Both of these propositions are disproved by a vast and consistent body of scientific evidence. The ages of the various rock formations, the Earth, the Moon, and meteorites have been measured using radiometric also called isotopic dating techniques — atomic clocks within the rocks themselves that, if properly used, reveal the elapsed time since the rocks formed.
There is overwhelming scientific evidence that the oldest rocks on the Earth are 3.
Older fossils cannot be dated by carbon methods and require radiometric dating. Scientists can use different chemicals for absolute dating: The best-known absolute dating technique is carbon dating, which archaeologists prefer to use.
My picture showed a water tap dripping into the cylinder. It was clearly marked so my audience could see that it held exactly ml of water. The diagram also showed that the water was dripping at a rate of 50 ml per hour. How did you work that out? Every dating method that scientists use works exactly the same way. It involves measuring something that is changing with time. Can you tell me what happened? But can you see what you are doing? You assumed the rate had always been 50 ml per hour and that the cylinder was empty when it started.
Based on those assumptions you calculated the time of 6 hours. Not one of you challenged it.

To Jenkins’ Spoiler-Laden Guide to Isaac Asimov Introduction Though perhaps best known throughout the world for his science fiction, Isaac Asimov was also regarded as one of the great explainers of science. His essays exemplified his skill at making complex subjects understandable, and were written in an unformal style, liberally sprinkled with personal anecdotes that endeared him to a legion of faithful readers.
It was all a labor of love; in particular Asimov often remarked that of all his writing, his essays for The Magazine of Fantasy and Science Fiction were his favorite, despite the fact that he received the lowest word-rate payment for them. From November to February , an essay of his appeared in the magazine every month, without fail. With the advent of Isaac Asimov’s Science Fiction Magazine in , he began a series of editorials that appeared at the beginning of each issue.
Biostratigraphy: One of the first and most basic scientific dating methods is also one of the easiest to understand. Layers of rock build one atop another — find a fossil or artifact in one layer, and you can reasonably assume it’s older than anything above it.
