Renaissance Now, let’s look at some specific examples. One type of atom that does not normally react is Neon. See the picture to the left. It already has the correct number of electrons in it’s outside electron layer so Neon does not react. Neon, along with Helium and Argon are known as non-reacting gasses because they do not need to react to be stable. Other types of atoms such as Hydrogen, Carbon, and Oxygen do not have the correct number of electrons to be stable by itself.

At the time that Darwin’s On the Origin of Species was published, the earth was “scientifically” determined to be million years old. By , it was found to be 1. In , science firmly established that the earth was 3. Finally in , it was discovered that the earth is “really” 4. In these early studies the order of sedimentary rocks and structures were used to date geologic time periods and events in a relative way.
The decades-old dogma that the acid-forming quality of animal protein leads to bone loss has been called into question. Below is an approximation of this video’s audio content. To see any graphs, charts, graphics, images, and quotes to which Dr. Greger may be referring, watch the above video. For.
Many such lines of evidence multiplying as at youngearth. On how to date a dinosaur, Real Science Radio’s Bob Enyart interviews Hugh Miller, a member of the international scientific team that presented at the AGU geophysical conference in Singapore, the carbon dating results from five respected laboratories around the world of bones from ten dinosaurs from the Gobi Desert in China, from Europe, Alaska, Texas, and Montana. Yet each of these dinosaurs had plenty of radiocarbon as expected in that virtually every relevant peer-reviewed paper on the topic confirms the presence of endogenous soft tissue in fossils; see DinosaurSoftTissue.
With the scientific breakthroughs and discoveries coming in daily, this is a great time to be alive! An expert on radiocarbon dating, long-time assistant professor at Loma Linda University, Dr. Paul Giem himself, graded the information presented below. You can hear that interview with Dr. He gave the original text available here a grade of A minus.
Carbon 14 doesn’t lie. Yet 14c is everywhere it shouldn’t be. Unless from a secondary source, like contamination or neutron capture described below , anything millions of years old should have NO Carbon A secondary assumption by old-earth scientists proposes that the C in diamonds coal, etc. Theoretical physicist Lawrence Krauss emphasis on the theoretical told RSR that 14c in allegedly million-year-old specimens is an “anomaly.

Amino Acid Dating Introduction. Amino acid dating has an important attribute in common with Carbon 14 dating. While most other dating mechanisms date the rock surrounding fossils, both Amino Acid and Carbon 14 dating methods, date the actual fossil itself.
The “Design Flaw ” Argument Oh, but what about the “design flaws” of the human eye? It is a common argument in favor of evolution that no intelligent designer would design anything with flaws. Evolution on the other hand, being a naturalistic process of trial and error, easily explains the existence of flaws in the natural world.
Although many are convinced by this argument, this argument in and of itself assumes the motives and capabilities of the designer. To say that everything designed should match our individual conceptions of perfection before we can detect design, is clearly misguided. Some might question the design of a Picasso painting, but no one questions the fact that it was designed, even having never met Picasso. A child might build a box car for racing the neighborhood kids in a box car derby.
Or, someone might deliberately alter the design of a previous designer for personal reasons. This alteration itself is designed by a new designer and can be detected as such. Although not “beneficial” to overall function or the intentions of the original designer, the alteration might still be understood to be designed. For example, if someone slices the tires on a car with a razor blade, would it be accurate for someone walking by afterward to automatically assume that an evolutionary process was at work because of the presence of this current supposed design flaw?
While a sliced up tire might not seem logical for a designer of tires to create, the flaw itself does not automatically rule out a designer.
Ornithine and S-adenosylmethionine are precursors of polyamines. Some non-standard amino acids are used as defenses against herbivores in plants. Uses in industry[ edit ] Amino acids are used for a variety of applications in industry, but their main use is as additives to animal feed. This is necessary, since many of the bulk components of these feeds, such as soybeans , either have low levels or lack some of the essential amino acids: These fertilizers are also used to prevent deficiencies from occurring and improving the overall health of the plants.
They include 5-HTP 5-hydroxytryptophan used for experimental treatment of depression,  -DOPA L -dihydroxyphenylalanine for Parkinson’s treatment,  and eflornithine drug that inhibits ornithine decarboxylase and used in the treatment of sleeping sickness.

Meanwhile, in Australia, the Bradshaw Paintings c. Northern and Western Europe c. Mesolithic Art , for details. Mesolithic was a short intervening period between the hunter-gatherer culture of the Paleolithic Old Stone Age and the farming culture of the Neolithic New Stone Age , during which the ice retreated to the poles and melted. In ice-free regions, there is a shorter Mesolithic period called Epipaleolithic or else the Neolithic period begins immediately, leading to more sophicated sculpture, open-air rock art and the growth of clay-fired ceramics.
Neolithic art , for details. The Neolithic age witnesses the beginning of civilization in the lands of Sumer, see Mesopotamian art and Mesopotamian sculpture , Egypt and Persia, as well as the Indus Valley civilization in India. Cities like Jericho, Ur are built, requiring all sorts of architecture and forms of public art. Tomb art, exemplified by Egyptian pyramids , becomes highly developed: Pictographs and modern systems of writing appear. Europe experiences a much later Neolithic period, and lags behind artistically.
Instead of fine art, European artists and architects focus on tomb-building using large megaliths adorned with carvings, engravings and other types of megalithic art.

While L -amino acids represent all of the amino acids found in proteins during translation in the ribosome, D -amino acids are found in some proteins produced by enzyme posttranslational modifications after translation and translocation to the endoplasmic reticulum, as in exotic sea-dwelling organisms such as cone snails. In alternative fashion, the S and R designators are used to indicate the absolute stereochemistry.
Amino acids are usually classified by the properties of their side chain into four groups. The side chain can make an amino acid a weak acid or a weak base , and a hydrophile if the side chain is polar or a hydrophobe if it is nonpolar.

To see any graphs, charts, graphics, images, and quotes to which Dr. Greger may be referring, watch the above video. For most of the last century, a prevailing theory within the field of nutrition was that by eating acid-forming foods such as meat , we were, in essence, at risk of peeing our bones down the toilet. Experiments dating back to showed over and over that if you add meat to the diet, you get a big spike in the amount of calcium being lost in the urine.
And so, this made total sense; we had known since that meat was acid-forming within the body. And, how do you buffer acid? What are in antacid pills, anti-acid pills—like Tums? Meat and eggs have a lot of sulphur-containing amino acids two to five times more than grains and beans that are metabolized into sulphuric acid, which the body buffers with calcium. Calcium can buffer acid. And, where is calcium stored in the body?
Racemization occurs when one pure form of an enantiomer is converted into equal proportion of both enantiomers, forming a racemate. When there are both equal numbers of dextrorotating and levorotating molecules, the net optical rotation of a racemate is zero. Physical properties[ edit ] Racemate may have different physical properties from either of the pure enantiomers because of the differential intermolecular interactions see Biological Significance section.

Herbchronology Dating methods in archaeology[ edit ] Same as geologists or paleontologists , archaeologists are also brought to determine the age of ancient materials, but in their case, the areas of their studies are restricted to the history of both ancient and recent humans. Thus, to be considered as archaeological, the remains, objects or artifacts to be dated must be related to human activity.
It is commonly assumed that if the remains or elements to be dated are older than the human species, the disciplines which study them are sciences such geology or paleontology, among some others. Nevertheless, the range of time within archaeological dating can be enormous compared to the average lifespan of a singular human being. As an example Pinnacle Point ‘s caves, in the southern coast of South Africa , provided evidence that marine resources shellfish have been regularly exploited by humans as of , years ago.
It was the case of an 18th-century sloop whose excavation was led in South Carolina United States in Dating material drawn from the archaeological record can be made by a direct study of an artifact , or may be deduced by association with materials found in the context the item is drawn from or inferred by its point of discovery in the sequence relative to datable contexts. Dating is carried out mainly post excavation , but to support good practice, some preliminary dating work called ” spot dating ” is usually run in tandem with excavation.
Dating is very important in archaeology for constructing models of the past, as it relies on the integrity of dateable objects and samples.
