Marshall The straits failed and flooded the Mediterranean A miembro de la familia to me wrote the following in response to a post I had made on a long running thread on his Facebook page. See, that one makes a lot of sense and is believable in some way. But there there is the submerged cities in the Mediterranean that sort of lend one to think the Straits failed and the atlantic flooded the then arid Med area. See, there are actual scientific things that provide reasonable and logical explanations for certain things. It points out the problem with naturalists trying hard to come with something that might be possible, without considering the probability of it actually being able to occur. Yeah, that makes the most sense. It is the most logical story, explains completely all the other civilizations not existing at all, anywhere on the planet, how liquid water totally disappeared and why no other person anywhere had a boat.


Panel 3 in Maltravieso Cave showing 3 hand stencils centre right, centre top and top left. One has been dated to at least 66, years ago and must have been Collado Scientists have found the first major evidence that Neanderthals, rather than modern humans, created the world’s oldest known cave paintings – suggesting they may have had an artistic sense similar to our own.

A new study led by the University of Southampton and the Max Planck Institute for Evolutionary Anthropology shows that paintings in three caves in Spain were created more than 64, years ago – 20, years before modern humans arrived in Europe. This means that the Palaeolithic Ice Age cave art – including pictures of animals, dots and geometric signs – must have been made by Neanderthals, a ‘sister’ species to Homo sapiens, and Europe’s sole human inhabitants at the time.

It also indicates that they thought symbolically, like modern humans.

According to the Greenville Police Department September activity report, there was one felony incident, one misdemeanor, two people arrested on warrants, and officers issued eight traffic citations.

La Tene Celtic culture, sculpture Types The majority of prehistoric cave paintings were figurative and 99 percent of these were of animals. At first, Stone Age artists painted predator animals lions, rhinoceroses, sabre-toothed felines, bears almost as often as game animals like bison and reindeer, but from the Solutrean era onwards imagery was dominated by game animals. Pictures of humans were an exceptionally rare occurrence, and were usually highly stylized and far less naturalistic than the animal figures.

Abstract imagery signs, symbols and other geometric markings was also common, and actually comprises the oldest type of Paleolithic art found in caves of the Late Stone Age, as shown by recent dating results on paintings at El Castillo and Altamira. In addition to figure painting and abstract imagery, prehistoric caves are also heavily decorated with painted hand stencils rock art , most of which – according to recent research by Dean Snow of Pennsylvania State University – were made by females, but men and children were also involved.

Cave Painting in Three Stages Typically a polychrome cave painting was created in three basic stages, which might vary significantly according to the experience and cultural maturity of the artist, the nature and contours of the rock surface, the strength and type of light, and the raw materials available. Take a picture of a bison, for instance. First, the outline and basic features of the animal are drawn on the cave wall, either by scoring the surface of the rock with a sharpened stone, or by applying a black outline using charcoal or manganese.

Feb 22,  · To determine the age of the paintings, the researchers used a technique known as uranium-thorium dating that measures the age of calcitic crusts that form on the walls of caves.

Uranium-Thorium dating is based on the detection by mass spectrometry of both the parent U and daughter Th products of decay, through the emission of an alpha particle. The decay of Uranium to Thorium is part of the much longer decay series begining in U and ending in Pb. With time, Thorium accumulates in the sample through radiometric decay. The method assumes that the sample does not exchange Th or U with the environment i.

The method is used for samples that can retain Uranium and Thorium, such as carbonate sediments, bones and teeth. Ages between and , years have been reported. Journal of Quaternary Science

• radiometric dating (which uses the concept of radioactive decay) is the most common method of absolute dating Thorium Lead Uranium Lead Uranium Lead Carbon 14 Nitrogen Each radioactive isotope has its own unique half-life.

See Article History Alternative Title: The important characteristic of common lead is that it contains no significant proportion of radiogenic lead accumulated since the time that the mineral or rock phase was formed. Of the four isotopes of lead, two are formed from the uranium isotopes and one is formed from the thorium isotope; only lead is not known to have any long-lived radioactive progenitor.

Primordial lead is thought to have been formed by stellar nuclear reactions, released to space by supernovae explosions, and incorporated within the dust cloud that constituted the primordial solar system; the troilite iron sulfide phase of iron meteorites contains lead that approximates the primordial composition. The lead incorporated within the Earth has been evolving continuously from primordial lead and from the radioactive decay of uranium and thorium isotopes.

Thus, the lead isotopic composition of any mineral or rock depends upon its age and the environment from which it was formed; that is, it would depend upon the ratio of uranium plus thorium to lead in the parent material. The Earth can be assumed to be a very large sample containing lead evolving from primordial lead by radiogenic increments. If modern lead, for example, from marine sediments or modern basalts has the composition of lead in the Earth and if the lead in the troilite phase of iron meteorites has the composition of primordial lead, then a simple model yields about 4.

This age is in good agreement with the age of the meteorites and the age of the Moon as determined independently. Learn More in these related Britannica articles:

Uranium-Lead dating

Like its predecessor the Pleistocene, the Holocene epoch is a geological period, and its name derives from the Greek words “holos”, whole or entire and “kainos”, new , meaning “entirely recent”. It is divided into 4 overlapping periods: Prehistoric Culture The longest phase of Stone Age culture – known as the Paleolithic period – is a hunter-gatherer culture which is usually divided into three parts: After this comes a transitional phase called the Mesolithic period sometimes known as epipaleolithic , ending with the spread of agriculture, followed by the Neolithic period the New Stone Age which witnessed the establishment of permanent settlements.

Feb 22, 2: A red hand stencil. A series of lines that look like a ladder. A collection of red dots. These images, painted in ocher on the walls of three separate caves in Spain, are the oldest-known examples of cave art ever found. And new research suggests that all three were created not by humans, but by our ancient cousins the Neanderthals. In a paper published Thursday in Science , an international team of archaeologists shows that each of the three paintings was executed at least 64, years ago — more than 20, years before the first modern humans arrived in Europe.

The ladder shape, composed of red horizontal and vertical lines, dates to older than 64, years and must have been made by Neanderthals. Saura, Breuil et al. For most of the last century, researchers have argued that our Neanderthal cousins were intellectually inferior to their modern human contemporaries — incapable of symbolic thought and possibly devoid of language. This, in turn, was used to explain why the Neanderthals disappeared from Eurasia about 40, years ago, not long after modern humans arrived there.

Uranium Thorium

The four isotopes are uranium , uranium , lead , and lead The process of dating finds the two ratios between uranium and lead ; and uranium and lead The radiometric dater then uses the half-life of all four isotopes to find an age range the rock should be in.

We found, by means of uranium/thorium dating of fossil corals, that sea level during the penultimate deglaciation had risen to ~85 meters below the present sea level by , years ago, and that it fluctuated on a millennial time scale during deglaciation.

What makes us human? A lot of people would argue it is the ability of our species to engage in complex behavior such as using language, creating art, and being moral. However, evidence for such behavior by other human species is far more contentious. One of them is at least 66, years old and was made by Neanderthals. Dating cave art Unfortunately, we have a poor understanding of the origins of cave art, primarily due to difficulties in accurately dating it.

Even when it is—such as when a charcoal-based pigment has been used—it suffers from issues of contamination, which can lead to inaccurate dates. It is also a destructive technique, as the sample of pigment has to be taken from the art itself. Tiny speleothem formations are often found on top of cave paintings, making it possible to use this technique to constrain the age of cave art without impacting on the art itself. A new era We used uranium-thorium dating to investigate cave art from three previously discovered sites in Spain.

They show for the first time that Neanderthals did produce cave art, and that it was not a one-off event. It was created in caves across the full breadth of Spain, and at Ardales it occurred at multiple times over at least an 18, year period. Excitingly, the types of paintings produced red lines, dots, and hand stencils are also found in caves elsewhere in Europe, so it would not be surprising if some of these were made by Neanderthals, too.

On the right, a drawing made by an archaeologist in shows animals and other symbols that are difficult to see on the cave wall.

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: These methods — some of which are still used today — provide only an approximate spot within a previously established sequence: Think of it as ordering rather than dating.

One of the first and most basic scientific dating methods is also one of the easiest to understand.
