How Good Are Those Young-Earth Arguments?

Periods of the Cenozoic Era Palaeogene about In addition, the Palaeogene and Neogene periods of the Cenozoic era often are lumped together as a subera called the Tertiary. By substituting that name for those of the two periods, it is possible to use a time-honored mnemonic device by which geology students have memorized the names of the 11 Phanerozoic periods: An epoch is the fourth-largest division of geologic time and is, for the most part, the smallest one with which we will be concerned. There are two smaller categories, the age and the chron. Listed here are the epochs of the Cenozoic era from the most distant to the Holocene, in which we are now living. Their names are derived from Greek words whose meanings are provided: Epochs of the Cenozoic Era Paleocene about Moreover, the history of life on Earth is so filled with detail and complexity that it could fill many books, as indeed it has. Owing to that complexity, anything approaching an exhaustive treatment of the subject would burden the reader with so much technical terminology that it would obscure the larger overview of paleontology and the materials of the paleontologist’s work.

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.

The theory of evolution proposes an explanation for how life in general and mankind in particular arose. It holds that that there was a long period in which natural processes gave rise .

Furthermore, if we were the product of a purely random processes then we have good reason to doubt our mental faculties when it comes to knowing the truth. Because our mental faculties would be the result of a random evolutionary process which is aimed, not at producing true beliefs, but at mere survival. But if that were the case then why should we trust the idea that we are the product of purely random factors?

The mental processes leading to this conclusion would not be aimed at producing true beliefs. I think that this line of argument is mistaken for two reasons. First, it seems as though there is a connection between survival and reliable beliefs. Consider three equal-sized groups of a particular species with beliefs: A, B and C.

A have generally reliable beliefs. B and C have generally unreliable beliefs, but B’s beliefs help them survive in their current environment and C’s beliefs do not.

Radiometric dating In , shortly after the discovery of radioactivity , the American chemist Bertram Boltwood suggested that lead is one of the disintegration products of uranium, in which case the older a uranium-bearing mineral the greater should be its proportional part of lead. Analyzing specimens whose relative geologic ages were known, Boltwood found that the ratio of lead to uranium did indeed increase with age.

After estimating the rate of this radioactive change, he calculated that the absolute ages of his specimens ranged from million to 2.

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.

Were Darwin’s Galapagos Finches Evolution? What does happen in a population as the genome reacts to the environment? Darwin looks at the finches on the Galapagos Islands and notices variations in beak size. He thought that the harder seed in the dry time was causing the beaks of the finches to grow stouter from the use of the part. But what was happening was that natural selection or a long term drought in the islands was causing the seed cases to harden.

The heavier beaked finch allele in the genome was favored and the lighter beaked finch allele was not. The heavier beaked finch became more dominant because it passed on the heavy beak alleles.

Environment

During the Pleistocene, mountain glaciers formed on all the continents and vast glaciers, in places as much as several thousand feet thick, spread across North America and Eurasia. In the eastern U. The Cenozoic [Recent Life] Era is divided into two main sub-divisions: Most of the Cenozoic is the Tertiary, from 65 million years ago to 1.

Relative dating is the science of determining the relative order of past events (i.e., the age of an object in comparison to another), without necessarily determining their absolute age, (i.e. estimated age).In geology, rock or superficial deposits, fossils and lithologies can be used to correlate one stratigraphic column with another. Prior to the discovery of radiometric dating in the early.

Would you like to merge this question into it? MERGE already exists as an alternate of this question. Would you like to make it the primary and merge this question into it? MERGE exists and is an alternate of. The first technique is called “relative dating. When one finds layers at an angle, especially at a sharp angle, one can regard the formation as due to shifts in the earth that occurred after the layers were deposited. When one sees that one kind of rock cuts across layers of other kinds of rock, one can regard the intruding rock material as younger.

Rock material enclosed in another kind of rock material can be regarded as older than the enclosing material. Relative dating is basically studying the layers of rock exposed at a site and making common-sense inferences about how the layers could have been formed so as to produce the layering one sees.

How do scientists know the age of fossils?

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.

Scientists determine the ages of once-living things by measuring the amount of carbon in the material. For biological objects older than 50, years, scientists use radioactive dating to determine the age of rocks surrounding where the material was found. By dating rocks, scientists can approximate ages of very old fossils, bones and teeth.

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. The Wheeler Formation has been previously dated to approximately million year old, so we know the trilobite is also about million years old.

Scientists can use certain types of fossils referred to as index fossils to assist in relative dating via correlation. Index fossils are fossils that are known to only occur within a very specific age range. Typically commonly occurring fossils that had a widespread geographic distribution such as brachiopods, trilobites, and ammonites work best as index fossils. If the fossil you are trying to date occurs alongside one of these index fossils, then the fossil you are dating must fall into the age range of the index fossil.

Radiometric Dating and the Geological Time Scale

Remote-controlled turtles can do your bidding, from… um … swimming in shallow waters? While most of the current methods cause involuntary behavior in animals by electronically stimulating the corresponding brain area or muscle, we show that, in turtles, it is also possible to control certain types of behavior, such as movement trajectory, by evoking an appropriate voluntary instinctive behavior.

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.

In reference to the sermon held in the city of Buenos Aires on May 16, , when he was still Cardinal Distinguished Mr. Allow us to turn to your person to clarify a few points made by you regarding Gnosis. You say that we need, before anything, an evangelizing Church. Unquestionably the work of evangelization is very laudable, but you must first of all know that the Catholics are not the only evangelizers of our troubled world, there are also evangelizers of other religious currents that have been very much detested by the Church over which you preside.

And in this work we include not only to provide a doctrinaire message to the people, but also to feed the hungry, give drink to the thirsty, clothe the naked, teach the ignorant, etc. Do you, respectable Mr. Thus it is in the sacred religions of the East such as the Hinduism, which shows us Shiva representation of the Holy Spirit as the husband of Shakti, a virgin that symbolizes the eternal divine feminine. In Christianity this Holy Spirit was symbolized, as we all know, by a white dove.

Remind yourself that all true religions, including the ancient theologies, were grounded on a holy Trimurti. Exercise the memory, Mr. God in Hebrew Elohim is translated as Gods and Goddesses.

Does Evolution Contradict Genesis?

Shop Now Scientists use a technique called radiometric dating to estimate the ages of rocks, fossils, and the earth. Many people have been led to believe that radiometric dating methods have proved the earth to be billions of years old. With our focus on one particular form of radiometric dating—carbon dating—we will see that carbon dating strongly supports a young earth.

Young-earth “proof” # The Sahara desert is expanding; it can only be a few thousand years old. The present Sahara Desert really is only a few thousand years old. About 7 or 8 thousand years ago the area underwent a pronounced wet phase and portions of it were habitable parkland where cattle could be grazed (The Times Atlas of World History, ).

The Sahara desert is expanding; it can only be a few thousand years old. The present Sahara Desert really is only a few thousand years old. About 7 or 8 thousand years ago the area underwent a pronounced wet phase and portions of it were habitable parkland where cattle could be grazed The Times Atlas of World History, More than 10, years ago, during the last glaciation, lakes and streams were present in the Sahara, and elephants, giraffes, and other animals roamed the grasslands and forests which covered much of the region.

Not long ago radar was used to discover a fossil river which once flowed across the Sahara; the river bed is now buried beneath the desert sands. By the way, what does any of this have to do with the age of the earth? Given the rate of salt influx to the oceans, they should be much saltier than they are if the earth were billions of years old. Hovind is assuming that salt cannot be removed from the oceans. The more sophisticated creationists, such as Melvin Cook, know better than to make that assumption.

How Is Radioactive Dating Used to Date Fossils?

The Potassium Argon Reaction Ar 40 is used for several reasons. First of all, Argon is inert. It does not chemically react with other elements at all. So Argon does not attach itself to the rock or any minerals in the rock.

How radiometric dating works in general: Radioactive elements decay gradually into other elements. The original element is called the parent, and the result of the decay process is called the daughter element.

Potential of abundant, environmentally harmless energy technology , which already exists My strategy for manifesting that energy event for humanity’s and the planet’s benefit. I w as born in In that same year, I had my cultural and mystical awakenings. During my second year of college, I had my first existential crisis and a paranormal event changed my studies from science to business.

I s till held my energy dreams, however, and in , eight years after that first paranormal event, I had a second one that suddenly caused me to move up the coast from Los Angeles to Seattle, where I landed in the middle of what is arguably the greatest attempt yet made to bring alternative energy to the American marketplace. That effort was killed by the local electric industry , which saw our technology as a threat to its revenues and profits, and my wild ride began. The owner of the Seattle business left the state to rebuild his effort.
