Dating refers to the archaeological tool to date artefacts and sites, and to properly construct history. All methods can be classified into two basic categories: Based on a discipline of geology called stratigraphy, rock layers are used to decipher the sequence of historical geological events. Relative techniques can determine the sequence of events but not the precise date of an event, making these methods unreliable. These methods are based on calculating the date of artefacts in a more precise way using different attributes of materials. This method includes carbon dating and thermoluminescence. The first method was based on radioactive elements whose property of decay occurs at a constant rate, known as the half-life of the isotope. Today, many different radioactive elements have been used, but the most famous absolute dating method is radiocarbon dating, which uses the isotope 14C.
The genome of the MA-1 revealed that an Upper Palaeolithic population from this region admixed with ancestors of present-day East Asians, giving rise to the First American gene pool. Niobe Thompson A Danish-led international research team has mapped the hitherto oldest genome of an anatomically modern human: Surprisingly, the genetic material reveals that the boy was European, which means that a European culture reached all the way east to Lake Baikal. In other words, Native Americans have partly European ancestry.
This paints a new picture of Native Americans and at the same time solves a number of puzzles regarding the colonisation of America. The study has just been published in the journal Nature ; however, the results started to leak out about a month ago, after Willerslev spoke about the discovery at a conference in the US.
The bones, dating to the first few centuries AD or earlier, belong to grey whales and North Atlantic right whales – coastal migratory species that are no longer found in European waters.
There’s a surprising new wrinkle in the story of the celebrated Shroud of Turin. A group of Italian researchers have found that the foot-long garment — believed by some to be the burial cloth of Jesus Christ, even though scientific research suggests that’s not the case — contains DNA from plants found all over Earth. Gianni Barcaccia, a plant genetics and genomics professor at the University of Padova in Italy, wrote in a paper co-authored with his colleagues about the DNA results.
Story continues below map. The linen shroud appears to show a double image of a bearded man “who suffered physical trauma in a manner consistent with crucifixion after being beaten, scourged and crowned with thorns,” the researchers wrote. But whether this man was the historic Jesus Christ has been the subject of decades of scrutiny, speculation and controversy over its authenticity and origin.
In , carbon testing performed on the cloth by an international team of researchers, dated shroud fibers back to between and But a study by a retired chemist from Los Alamos National Laboratory dismissed that finding , arguing that the material tested in came from a patch applied to the shroud in medieval times. The study put the age of the shroud at 1, to 3, years.
The finding from a team of Israeli archaeologists and mathematicians counters notions that literacy was rare and isolated before the Jews’ exile to Babylon. It really puts a damper into the liberals who have hounded us that most of [the Old Testament] was developed during the intertestamental period or the Babylonian captivity. That’s just one more nail slammed in the coffin. This finding — combined with previous archaeological discoveries — suggests a widespread “ability to communicate in writing” among all socioeconomic classes in ancient Israel, according to the article.
This article shows that writing was a common practice in Israel prior to the exile and refutes this argument. In fact, Judges 8:

DNA sequencing was conducted on five skeletons from Canaanite Sidon, including this one. Courtesy of Claude Doumet-Serhal. What happened to the Canaanites? The Canaanites were a Semitic-speaking cultural group that lived in Canaan comprising Lebanon, southern Syria, Israel and Transjordan beginning in the second millennium B.
In the Hebrew Bible, the Canaanites are described as inhabitants of Canaan before the arrival of the Israelites e. The researchers sequenced the genomes of five individuals who were buried in the Canaanite city of Sidon in Lebanon around B. The results of their study demonstrated a connection: Other than Israel, no country has as many Biblical sites and associations as Jordan: Travel with us on our journey into the past in our free eBook Exploring Jordan.

Saturday 15 April On a bright but bitterly cold January afternoon earlier this year, I found myself on a small island in the Black Sea, just off Sozopol on the east coast of Bulgaria. Sveti Ivan has long been a destination for travellers: But I was there to speak to an old Bulgarian archaeologist about the most important find of his career.
In , Kasimir Popkonstantinov discovered what he believes are the bones of one of the most famous of all saints: I was interested in what DNA analysis could tell us about these bones, and other ones.
I would like to briefly review the history of DNA in archaeology and ask of DNA from brain material from a neutral bog dating from the Archaeology and DNA. C.J.C. Reuvenslezing—
Alamy Ancient bones found around the Strait of Gibraltar suggest that the Romans might have had a thriving whaling industry, researchers have claimed. The bones, dating to the first few centuries AD or earlier, belong to grey whales and North Atlantic right whales — coastal migratory species that are no longer found in European waters. Researchers say this not only suggests these whales might have been common around the entrance to the Mediterranean in Roman times, but that Romans might have hunted them.
They add that Romans would not have had the technology to hunt whale species found in the region today – sperm or fin whales which live further out at sea – meaning evidence of whaling might not have been something archaeologists and historians were looking out for. The right whale was once widespread in the North Atlantic, with breeding grounds off the northern coast of Spain and north west Africa, but was hunted by Medieval Basque whalers among others, and are now only found in the Western North Atlantic.
Grey whales disappeared from the North Atlantic some time in the 18th century, and are now only found in the Pacific. While there are a handful of historical reports of right whales cropping up in the Mediterranean, the only reliable grey whale sighting in the region was in and is thought to have been a misguided individual that turned up from the Pacific. Writing in the journal Proceedings of the Royal Society B , Rodrigues and a team of archaeologists and ecologists, describe how they set out to unpick the issue by examining 10 bones — thought to be from whales — collected during recent archaeological digs or housed in museum collections.
Unfortunately, while many Palaeolithic sites contain large numbers of bones, the majority of these lack the diagnostic features necessary for traditional morphological identification. As a result the recovery of Pleistocene-age human remains is extremely rare. To circumvent this problem we have applied a method of collagen fingerprinting to more than fragmented bones from the site of Denisova Cave, Russia, in order to facilitate the discovery of human remains.
As a result of our analysis a single hominin bone Denisova 11 was identified, supported through in-depth peptide sequencing analysis, and found to carry mitochondrial DNA of the Neandertal type. Here we demonstrate the huge potential collagen fingerprinting has for identifying hominin remains in highly fragmentary archaeological assemblages, improving the resources available for wider studies into human evolution.
Denisova Cave is a key site for our understanding of the north Asian Palaeolithic record.

This has caused quite an uproar, in both genetic genealogy and Native American research communities, and has been resoundingly discredited by geneticists. Curiosity and a desire to confirm a family story Desire to recover lost heritage Desire to identify or join a tribe Desire to obtain services provided to eligible tribal members, such as educational benefits Desire to obtain benefits provided to eligible tribal members, such as a share of casino profits Questions about DNA testing to reveal Native ancestry are the most common questions I receive and my Native DNA articles are the most visited on my website and blog.
Both Y and mitochondrial DNA have scientifically identified and confirmed haplogroups found only in Native Americans, as discussed in this article. However, if the Native ancestor does not descend from the direct paternal or direct matrilineal lines, the only DNA test left is an autosomal test which tests all of your ancestral lines, but which can only reliably identify ancestral heritage for the past 5 or 6 generations in any of those lines due to recombination of DNA with the other parent in each generation.
Autosomal tests provide you with percentage estimates of your ethnicity although they can vary widely between companies for various reasons. All three of these tests are available from Family Tree DNA as part of their normal product offering. Recently, one, Accu-Metrics out of Canada has been highly criticized in the media for informing a woman that she was related to or descended from the extinct Beothuk tribe based on a match to a partial, damaged, mitochondrial sample from skeletal remains, now in housed in Scotland.
When you look at some of these sites, they spend a lot of time convincing you about the qualifications of the lab they use, but the real problem is not with the laboratory, but their interpretation of what those results mean to their clients — e. In fact, we have people in the American Indian Project and various Native haplogroup projects who match each other with either Native Y or mitochondrial results who are tribally enrolled or descended from tribes from very different parts of the Americas, as far distant as Canada and South America.
An HVR1 level only match between two people could be from thousands to tens of thousands of years ago. There are individuals living in Europe and Asia, as well as the Americans who fall into various subgroups of haplogroup C and X, which are impossible to differentiate without testing beyond the HVR1 region. A match at the HVR1 level which only indicates C or X, without subgroups, could be from a very ancient common ancestor, back in Asia and does not necessarily indicate Native American heritage without additional testing.
However, with the development of the Polymerase Chain Reaction PCR in the late s, the field began to progress rapidly. Multiple primer, nested PCR strategy was used to overcome those shortcomings. Soon a series of incredible findings had been published, claiming authentic DNA could be extracted from specimens that were millions of years old, into the realms of what Lindahl b has labelled Antediluvian DNA.
Insects such as stingless bees,  termites,  and wood gnats,  as well as plant  and bacterial  sequences were extracted from Dominican amber dating to the Oligocene epoch. Still older sources of Lebanese amber-encased weevils , dating to within the Cretaceous epoch, reportedly also yielded authentic DNA. Several sediment-preserved plant remains dating to the Miocene were successfully investigated.
Should archaeologists really fear and loathe geneticists? Until this year, it may not have seemed apparent that every archaeological site will have ancient DNA techniques applied to it before long. Ewen Callaway in Nature has a long feature article focusing on the tension between archaeologists and ancient DNA specialists as they try to understand the past with their different approaches: The article has a number of recent examples, mainly big studies of ancient DNA that were published in Nature with results pointing to major population replacements or migrations that had been unexpected by archaeologists.
Genetic information from ancient populations has settled some year-old or even year-old debates in archaeology. For example, we now know that the Indo-European languages did not spread into Europe and India along with the Neolithic revolution and introduction of farming from Anatolia. Instead those languages spread later, from an early Bronze Age origin on the steppe. We now know that the introduction of Bell Beaker pottery across much of Europe was in some places a result of people changing their material culture to adopt the new pottery style, and in other places including England the result of new people invading and almost completely replacing the resident farmers.
Print this page How it works Certain chemical elements have more than one type of atom. Different atoms of the same element are called isotopes. Carbon has three main isotopes.
The ancient DNA comes from the teeth of 19 people, including 10 Minoans from Crete dating to B.C.E. to BCE, four Mycenaeans from the archaeological site at Mycenae and other cemeteries.
The Spore Conundrum Sporormiella is a fungus that grows on animal dung as part of its life cycle. A decline of Sporor A decline of Sporormiella reproductive spores in stratified Late Glacial pond sediments in Ohio, northern Indiana, and New York has been interpreted as a signal of regional extinction of megafauna due to human predation between 14, and 13, cal BP.
However, this interpretation is undermined by two salient evidential problems. First, numerous skeletons of mastodonts and mammoths in these areas date between 12, and 10, rcybp 14, e12, cal BP. Megaherbivores were thriving and expanding their range into recently deglaciated areas when the fungal spore evidence implies that they were instead functionally extinct. Second, the archaeological record of human activity in these areas prior to 13, cal BP is sparse to nonexistent.
Paul Berry After building the product for Huffington Post, and owning the product and engineering groups at AOL after we were acquired, it was clear to me there was a huge gap between what the current CMS offering gave the world and what the world needed. Five years later we are at scale, moving the needle and doing to WordPress what Airbnb did to Craigslist.

There are over 87 million instances of WordPress alone in the world, and each security upgrade, feature update, and every other single thing has to be updated for each site individually. By contrast, RebelMouse is a social, centralized platform built to keep up with the speed of the tech giants.

Megiddo is the jewel in the crown of biblical archaeology. Strategically perched above the most important land route in the ancient Near East, the city dominated international traffic for over 6, years — from ca. As civilizations came and went, succeeding settlements at ancient Megiddo were built on the ruins of their predecessors, creating a multi-layered archaeological legacy that abounds in unparalleled treasures that include monumental temples, lavish palaces, mighty fortifications, and remarkably-engineered water systems.

The Ancient One is closely related to at least one of the five tribes that originally fought to rebury him on spiritual grounds. Boyd says that the Colville people, who provided two dozen DNA samples for comparison with Kennewick Man, are now discussing whether to reclaim the skeleton under U. Army Corps of Engineers, which currently has legal custody of Kennewick Man, is also studying whether to return the nearly complete skeleton—which was found eroding from the shore of the Columbia River in Kennewick, Washington, in —to the tribes.
For years there was no way to scientifically resolve the question, in part because tribes were able to claim many of the bones and rebury them, in accordance with their cultural practices, without genetic or other studies.

It is here were Peruvian archaeologist, Julio Tello, made an amazing discovery in — a massive and elaborate graveyard containing tombs filled with the remains of individuals with the largest elongated skulls found anywhere in the world. In total, Tello found more than of these elongated skulls, which are believed to date back around 3, years. A DNA analysis has now been conducted on one of the skulls and expert Brien Foerster has released preliminary information regarding these enigmatic skulls.
It is well-known that most cases of skull elongation are the result of cranial deformation, head flattening, or head binding, in which the skull is intentionally deformed by applying force over a long period of time. It is usually achieved by binding the head between two pieces of wood, or binding in cloth.
However, while cranial deformation changes the shape of the skull, it does not alter its volume, weight, or other features that are characteristic of a regular human skull.
