The premier listener email is from Roger, who writes: Thank you, and keep up the good work! According to Christianity, all humans alive today are descended from Adam and Eve. It’s also an easily observable fact that different groups of humans have very distinctive physical features Africans, Asians, Caucasians, etc. In the same way that we wouldn’t expect an African person to give birth to an Asian baby, we also wouldn’t expect a chimpanzee to give birth to a human baby. Instead, just like Africans, Asians, and Caucasians all have a common ancestor, chimpanzees and humans have a common ancestor. So asking why “chimps aren’t still evolving into humans” makes as much sense as asking why “Africans aren’t still evolving into Asians. Many creationists have jumped to this conclusion for the purpose of denouncing evolution as racist.

James Tour is a well-known professor at Rice University, specializing in chemistry, nanoengineering, and computer science. In a video released in late , Tour explained that he has had extensive experience studying the origin of life. I mean, ab initio, I make molecules. I understand how hard it is to make molecules. Is that all right?

And you would just say that, wow, I must be really unusual.

Geologists could confidently match the top of one rock unit to the base of the next time unit using fossils, thus layers could be matched (correlated is the geological term) across broad regions, even continents and placed in relative order from the oldest (Cambrian) to youngest (Quaternary).

General overview The evidence for evolution Darwin and other 19th-century biologists found compelling evidence for biological evolution in the comparative study of living organisms, in their geographic distribution, and in the fossil remains of extinct organisms. The amount of information about evolutionary history stored in the DNA and proteins of living things is virtually unlimited; scientists can reconstruct any detail of the evolutionary history of life by investing sufficient time and laboratory resources.

Darwin, CharlesOverview of Charles Darwin’s life, with a focus on his work involving evolution. The following sections identify the most productive of these sources and illustrate the types of information they have provided. The fossil record Paleontologists have recovered and studied the fossil remains of many thousands of organisms that lived in the past.

This fossil record shows that many kinds of extinct organisms were very different in form from any now living. It also shows successions of organisms through time see faunal succession, law of ; geochronology: Determining the relationships of fossils with rock strata , manifesting their transition from one form to another. When an organism dies, it is usually destroyed by other forms of life and by weathering processes.

On rare occasions some body parts—particularly hard ones such as shells, teeth, or bones—are preserved by being buried in mud or protected in some other way from predators and weather. Eventually, they may become petrified and preserved indefinitely with the rocks in which they are embedded. Methods such as radiometric dating —measuring the amounts of natural radioactive atoms that remain in certain minerals to determine the elapsed time since they were constituted—make it possible to estimate the time period when the rocks, and the fossils associated with them, were formed.

Radiometric dating indicates that Earth was formed about 4. The earliest fossils resemble microorganisms such as bacteria and cyanobacteria blue-green algae ; the oldest of these fossils appear in rocks 3.

The type species, Megalosaurus bucklandii, was established in Later, Megalosaurus was one of three genera on which Richard Owen based his identification of Mesozoic land reptiles, which he named Dinosauria, or “Terrible lizards. The other two founding members of the initial dinosaur grouping were the herbivorous Iguanodon, and the armoured Hylaeosaurus, both discovered by the geologist Gideon Mantell.

Evolution – Rescuing out-of-place Fossils

Generally, there are four main concepts that students struggle with when thinking about radioactive decay: A steady but unpredictable spontaneous process Radioactivity and radioactive decay are spontaneous processes. Students often struggle with this concept; therefore, it should be stressed that it is impossible to know exactly when each of the radioactive elements in a rock will decay.

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.

God places the cherubim, with a flaming sword, to guard the Tree of Life and Eden Gen. There is nothing in the Catechism that makes any teaching concerning original sin dependent on the sudden appearance of two immediately intelligent beings. Might we say that at some point in evolutionary history the mind of a being had the capacity to understand good and evil? Christianity and modern science are not at odds. To speculate otherwise, does no favor to either.

Sep 26,  · Methods such as radiometric dating—measuring the amounts of natural radioactive atoms that remain in certain minerals to determine the elapsed time since they were constituted—make it possible to estimate the time period when the rocks, and the fossils associated with them, were formed.

These are K-Ar data obtained on glauconite, a potassium-bearing clay mineral that forms in some marine sediment. Woodmorappe fails to mention, however, that these data were obtained as part of a controlled experiment to test, on samples of known age, the applicability of the K-Ar method to glauconite and to illite, another clay mineral. He also neglects to mention that most of the 89 K-Ar ages reported in their study agree very well with the expected ages.

Evernden and others 43 found that these clay minerals are extremely susceptible to argon loss when heated even slightly, such as occurs when sedimentary rocks are deeply buried. As a result, glauconite is used for dating only with extreme caution. The ages from the Coast Range batholith in Alaska Table 2 are referenced by Woodmorappe to a report by Lanphere and others Whereas Lanphere and his colleagues referred to these two K-Ar ages of and million years, the ages are actually from another report and were obtained from samples collected at two localities in Canada, not Alaska.

There is nothing wrong with these ages; they are consistent with the known geologic relations and represent the crystallization ages of the Canadian samples. The Liberian example Table 2 is from a report by Dalrymple and others These authors studied dikes of basalt that intruded Precambrian crystalline basement rocks and Mesozoic sedimentary rocks in western Liberia. The dikes cutting the Precambrian basement gave K-Ar ages ranging from to million years Woodmorappe erroneously lists this higher age as million years , whereas those cutting the Mesozoic sedimentary rocks gave K-Ar ages of from to million years.

Woodmorappe does not mention that the experiments in this study were designed such that the anomalous results were evident, the cause of the anomalous results was discovered, and the crystallization ages of the Liberian dikes were unambiguously determined. The Liberian study is, in fact, an excellent example of how geochronologists design experiments so that the results can be checked and verified. The final example listed in Table 2 is a supposed 34 billion-year Rb-Sr isochron age on diabase of the Pahrump Group from Panamint Valley, California, and is referenced to a book by Faure and Powell

Unlike relative dating, absolute dating of fossils involves establishing a discrete age (in years) to the fossils under study. This is generally done via radiometric dating in which the half life of a radioactive isotope is used to calculate how long the substances in the fossil have been decaying.

Relative dating uses observation of. What is Relative Dating? What is the difference between relative age and absolute age? Relative Dating , Fossils, and Radiometric Dating. Radiometric dating is one type of method used in absolute dating. Both relative dating and absolute dating are procedures used to give. The difference between relative dating and absolute dating is that relative.

UFOs and Fringe Science There are around human-made satellites in working order around the Earth, however if the debris of old and damaged satellites are taken into account the number increases dramatically. Ever since the Soviet Union launched the very first artificial satellite into orbit in , various countries around the world have sought to compete and satellites today are used for communication, navigation and exploration. Satellites are often visible passing overhead as the sunlight reflects back towards the Earth.

One of them is impossible to miss, the largest satellite currently in orbit, the International Space Station, at a huge m across. However, these satellites are relatively unexciting in comparison to the mystery surrounding one very old dark satellite… Mysterious unidentified flying satellite from STS Legend has it that in orbit around the Earth is a mysterious, dark object which dates back perhaps 13 years.

I don’t recall any dating methods, besides C, used to date organic material opposed to igneous rocks That could be because other dating methods don’t rely on being able to find organic material. this would account for why Creationists use C as a reference when discussing dating methods of organisms.
